Crib Mattresses Safety Standard Direct Final Rule

Content

ACTION:

Direct final rule.

SUMMARY:

In 2022, the U.S. Consumer Product Safety Commission (CPSC) published a consumer product safety standard for crib mattresses
under section 104 of the Consumer Product Safety Improvement Act of 2008 (CPSIA). The standard incorporated by reference ASTM
F2933-21, Standard Consumer Safety Specification for Crib Mattresses, with modifications to make the standard more stringent. The CPSIA sets forth a process for updating mandatory standards for
durable infant or toddler products that are based on a voluntary standard, when a voluntary standards organization revises
the standard. Consistent with the CPSIA update process, this direct final rule updates the mandatory standard for crib mattresses
to incorporate by reference ASTM's 2025 version of the voluntary standard, while maintaining certain modifications.

DATES:

The rule is effective on May 3, 2026, unless the Commission receives a significant adverse comment by March 16, 2026. If the
Commission receives such a comment, it will publish a document in the
Federal Register
, withdrawing this direct final rule before its effective date. The incorporation by reference of certain material listed
in this rule is approved by the Director of the Federal Register as of May 3, 2026.

SUPPLEMENTARY INFORMATION:

I. Background

A. Statutory Authority

Section 104(b)(1) of the CPSIA requires the Commission to assess the effectiveness of voluntary standards for durable infant
or toddler products and adopt mandatory standards for these products. 15 U.S.C. 2056a(b)(1). The mandatory standard must be
“substantially the same as” the voluntary standard, or it may be “more stringent than” the voluntary standard, if the Commission
determines that more stringent requirements would further reduce the risk of injury associated with the product. Id.

Section 104(b)(4)(B) of the CPSIA specifies the process for updating the Commission's rules when a voluntary standards organization
revises a standard that the Commission incorporated by reference under section 104(b)(1). First, the voluntary standards organization
must notify the Commission of the revision. Once the Commission receives this notification, the Commission may reject or accept
the revised standard. The Commission may reject the revised standard by notifying the voluntary standards organization, within
90 days of receiving notice of the revision, that it has determined that the revised standard does not improve the safety
of the consumer product and that it is retaining the existing standard. If the Commission does not take this action to reject
the revised standard, the revised voluntary standard will be considered a consumer product safety standard issued under section
9 of the Consumer Product Safety Act (15 U.S.C. 2058), effective 180 days after the Commission received notification of the
revision or on a later date specified by the Commission in the
Federal Register
. 15 U.S.C. 2056a(b)(4)(B).

B. Safety Standard for Crib Mattresses

Under section 104(b)(1) of the CPSIA, the Commission adopted a mandatory rule for crib mattresses, codified in 16 CFR part
1241, “Safety Standard for Crib Mattresses.” The rule incorporated by reference ASTM F2933-21, Standard Consumer Safety Specification for Crib Mattresses, with modifications to make the standard more stringent. 87 FR 8640 (Feb. 15, 2022). (1) The modifications to ASTM F2933-21 addressed:

(1) suffocation hazards associated with crib mattresses, due to overly soft mattresses, by adding a test for mattress firmness
based on sections 6 and 8 of AS/NZS 8811.1:2013—Methods of testing infant products—Method 1: Sleep Surfaces—Test (AS/NZS 8811.1);

(2) entrapment hazards associated with full-size crib mattresses, due to poor mattress fit from compression by sheets, by
measuring for corner gaps after installing a shrunken (by washing twice) cotton sheet;

(3) entrapment hazards associated with after-market, non-full-size crib mattresses, due to lack of dimensional requirements
for rectangular-shaped products, by extending dimension and other requirements for after-market non-rectangular non-full-size
crib mattresses to all after-market non-full-size crib mattresses;

(4) laceration hazards associated with coils and springs breaking and poking through mattresses, by adding a cyclic impact
test for mattresses that use coils and springs;

(5) the risks of sudden infant death syndrome (SIDS) and suffocation related to infant positioning, soft bedding, and gap
entrapment, by improving the labeling and instructional literature requirements to communicate risks better to consumers,
and to clarify requirements for manufacturers and test labs; and

(6) the replacement of references to ASTM standards with references to the corresponding CPSC regulation which incorporates
that standard by reference, to maintain consistency with CPSC regulations.

Since CPSC promulgated a final rule for crib mattresses in February 2022, staff continued to work with the ASTM F15.66 Crib
Mattresses Subcommittee to address differences between the voluntary standard and the final rule. On October 1, 2025, ASTM
approved and in October 2025, published a new version of the voluntary standard for crib mattresses, ASTM F2933-25. The revised
voluntary standard includes performance requirements and test methods, as well as requirements for warning labels and instructions,
to address hazards to infants. On November 4, 2025, ASTM notified CPSC of the newest revision to ASTM F2933. On December 3,
2025, the Commission provided notice in the
Federal Register
of the availability of the revised standard and sought comment on the effect of the revisions on the safety standard for crib
mattresses. 90 FR 55701. CPSC received four comments.

Two comments were duplicative and out of scope. An anonymous commenter stated their support for CPSC to approve and support
the revised voluntary standard. Another anonymous commenter expressed appreciation for CPSC's review of the voluntary standard.
The commenter acknowledged that some revisions improve safety, however, the commenter emphasized the importance of confirming
that the revisions reduce risks such as suffocation and entrapment in gaps. The commenter concluded by expressing support
for ASTM F2933-25 as long as CPSC determines that it improves safety compared to the existing mandatory standard.

CPSC acknowledges support for the revised voluntary standard and agrees with the importance of confirming that the revisions
to ASTM F2933-25 reduce risks such as suffocation and entrapment in gaps or otherwise improve the safety of crib mattresses.
CPSC's assessment of ASTM F2933-25 is described below.

Based on staff's review of ASTM F2933-25 and the public comments received, the Commission will allow the revised voluntary
standard to become a mandatory standard, with some retained

  modifications. Specifically, three modifications that address hazardous corner gaps, entrapment hazards for rigid-sided rectangular
  after-market products (*i.e.,* non-full-size cribs), and references to requirements in ASTM standards, as required by other CPSC regulations, will be maintained
  in 16 CFR part 1241. Specifically, ASTM F406-24, *Standard Consumer Safety Specification for Non-Full-Size Baby Cribs/Play Yards* (codified at 16 CFR part 1220 for non-full-size baby cribs and at 16 CFR part 1221 for play yards) include performance requirements
  and test methods, as well as requirements for warning labels and instructions, to address hazards to children from non-full-size
  baby cribs and play yards. ASTM F2194-25, *Standard Consumer Safety Specification for Bassinets and Cradles* (codified at 16 CFR part 1218) include performance requirements and test methods, as well as requirements for warning labels
  and instructions, to address hazards to children from bassinets and cradles. ASTM F2933-25 does not address these hazards
  or include references to the relevant CPSC regulations.

Accordingly, by operation of law under section 104(b)(4)(B) of the CPSIA, ASTM F2933-25 will become a mandatory consumer product
safety standard for crib mattresses, with some retained modifications, on May 3, 2026. 15 U.S.C. 2056a(b)(4)(B). This direct
final rule updates 16 CFR part 1241 to incorporate by reference the revised voluntary standard, ASTM F2933-25, and retains
modifications that maintain testing requirements for corner gaps, requirements for rectangular after-market non-full-size
crib mattresses, and references to CPSC regulations.

II. Revisions to ASTM F2933

ASTM F2933-25 includes several additions and revisions to ASTM F2933-21, including new definitions, new performance requirements
and test methods, clarifications to existing requirements, as well as editorial revisions that do not alter substantive requirements
in the standard or impact safety. The Commission considers the revisions in ASTM F2933-25 to be an improvement to the safety
of crib mattresses because the revised standard includes clarifications to the scope of the voluntary standard and enhancements
to the performance and testing requirements to improve testing repeatability and reproducibility.

A. Scope and Definitions

ASTM F2933-25 clarifies in section 1.1 that after-market mattresses for certain bassinet accessories of play yards are in
scope of the voluntary standard. ASTM F2933-21 included performance requirements for after-market play yard mattresses that
are interchangeably used as a play yard mattress and as a bassinet mattress/pad, but the scope did not specify that such mattresses
were addressed in the standard. The change to explicitly identify such mattresses for bassinet accessories of play yards as
being in scope improves safety by helping users of the standard understand which products are subject to its requirements.

Additionally, in section 3, ASTM F2933-25 adds definitions for “conspicuous” and for “sleep surface” that align with terms
that were added as a modification to ASTM F2933-21 in CPSC's mandatory safety standard for crib mattresses. As a result, the
change does not reduce safety, and these terms will be removed from the modifications in 16 CFR part 1241.

B. Calibration and Standardization

ASTM F2933-21 required that products be placed in a room with an ambient temperature of 73 °F ± 9 °F for at least 8 hours
prior to and during testing. ASTM F2933-25 adds a new requirement that the relative humidity shall be between 20 percent and
70 percent prior to and during testing.

The revisions to the voluntary standard in ASTM F2933-25 also lengthen the pre-conditioning from at least 8 hours, required
in ASTM F2933-21, to at least 24 hours or the duration specified in the manufacturer's instructions, whichever is longer,
for the mattress to fully inflate or recover to the intended size before testing.

These changes improve safety by reducing the chance of underinflated crib mattresses being tested and meeting the requirements,
when such mattresses would otherwise fail to meet the requirements when fully inflated or recovered.

C. Performance and Testing Requirements

1. Mattress Firmness

ASTM F2933-25 adds a firmness requirement and test method based on the modification in CPSC's mandatory safety standard for
crib mattresses with the following differences:

• The test fixture must use a bullseye level or two linear levels, instead of only one linear level. This helps ensure the test fixture is as flat as possible when determining whether a product meets the firmness requirement.
• A specification was added to require the combined weight of the bottom disk and the lower collar of the test fixture to be not less than 95 percent of the total weight, instead of specifying only the weight of the bottom disk and the total weight. This improves the precision of the test fixture.
• Specifications for the design and use of a rigid bar were added to achieve more consistent test results by flattening non-hazardous wrinkles or bulges in fabric in the test area.
• The test setup includes a clarification that the requirement to test mattresses sold independent of a product on a flat, rigid, horizontal support only applies to full-size crib mattresses, and not to after-market mattresses for play yards and non-full-size cribs. This helps ensure that crib mattresses are placed on the appropriate surface for testing.
• A step was added to flatten the test area before the fixture is placed. This helps to remove small amounts of loose fabric from the test area and improves testing repeatability and reproducibility. • The outer 0.5 inches of the mattress were removed from the possible test area. This section is excluded from testing because many modern mattress designs are difficult to test repeatably close to the outer edge, and because the area does not accommodate more than half of a newborn's accessible face: the 0.5 inches accounts for a 3-inch bizygomatic diameter newborn head size, (2) half of which is 1.5 inches, minus a 1 inch allowable gap between the mattress and crib. Therefore, this change improves testing repeatability and reproducibility without reducing safety.

In addition to these changes, the firmness test method was also rewritten with the intent of being more easily readable and
understandable and includes several other minor clarifications. Overall, the new firmness test is more repeatable and reproducible,
and therefore is an improvement in the safety of crib mattresses. As a result, the modification related to the firmness test
requirement is being removed from 16 CFR part 1241. Instead, crib mattresses will be subject to the firmness test requirements
included in ASTM F2933-25, incorporated by reference in 16 CFR part 1241.

2. Coil Springs

ASTM F2933-25 adds a requirement and test method for mattresses with coil springs to reduce the risk of lacerations caused
by coil springs poking out of the mattress. This change is consistent with

  a modification made in the mandatory safety standard for crib mattresses, with one exception. ASTM F2933-25 allows repeating
  the test on a mattress which has previously been tested with the coil spring test. Repeating the test on a single mattress
  is more likely to cause a product to fail; therefore, because this is a more stringent test, it is an improvement to safety.
  As a result of this revision, the modification that added a requirement and test method for mattresses with coil springs will
  be removed from 16 CFR part 1241. Instead, crib mattresses will be subject to the coil spring test requirements included in
  ASTM F2933-25, incorporated by reference in 16 CFR part 1241.

3. Other Changes

ASTM F2933-25 removes section 5.1 from ASTM F2933-21, which required products to meet all other applicable mandatory statutes
and regulations. This section was not necessary in the voluntary standard because compliance with all applicable mandatory
statutes and regulations remains obligatory for all products; therefore, this change does not impact safety. Modifications
to section 5 of ASTM F2933-25 have been renumbered in 16 CFR part 1241 to account for this change. In section 5.8.1.2, ASTM
F2933-25 replaces the word “pad” with “mattress” when referring to requirements in ASTM F2194, Consumer Safety Specification for Bassinets and Cradles. This change is a terminology update and does not impact the safety of any requirements in ASTM F2933. 16 CFR part 1241 is
also revised to reflect this change when referencing ASTM F2194 and 16 CFR part 1218, Safety Standard for Bassinets and Cradles. (3)

D. Warnings and Instructions

The warnings and instructions for ASTM F2933-25 have been updated to substantially align with modifications in the mandatory
standard for crib mattresses, with some minor deviations that are not expected to reduce safety. This includes minor changes
in wording or formatting that do not change the overall meaning, such as the following:

• In section 7.2, the word “mattress” is used in place of “product.”
• In section 7.5, the phrase “unless otherwise specified” is omitted from the phrase, “Each mattress shall have warning statements to address the following, at a minimum, unless otherwise specified.”
• In section 7.7, “shall include” is used instead of “shall have.” The revised voluntary standard also provides visual examples of warning labels exhibiting stated requirements in section 7 (FIG. 9, FIG. 10, and FIG. 11). These figures are similar to those included in the modifications.

Accordingly, these revisions to the warnings and instructions do not reduce safety. As a result, CPSC's modifications to the
marking and labeling and instructional literature requirements in 16 CFR part 1241 will be removed. Instead, crib mattresses
will be subject to the warning and instruction requirements included in ASTM F2933-25, incorporated by reference in 16 CFR
part 1241.

E. Other Revisions

ASTM F2933-25 also includes several minor additions and revisions that are editorial in nature, such as updates to section
and figure numbers to reflect revised and new sections and figures and an updated Rationale section. (4) These revisions do not impact safety because they do not alter any substantive requirements in the standard.

F. Modifications to the Standard

ASTM F2933-25 does not address the following modifications in the mandatory safety standard for crib mattresses:

• The addition of a mattress compression test to further reduce the risk of injury associated with corner gap entrapment from compression of the mattress by a fitted sheet.

• Extended dimension and other requirements for after-market non-rectangular non-full-size crib mattresses to all after-market
  non-full-size crib mattresses.
  • A reference to requirements in either 16 CFR part 1220, Safety Standard for Non-Full-Size Baby Cribs, or 16 CFR part 1221,
  Safety Standard for Play Yards, as appropriate, to ensure consistency with other mandatory requirements in addition to referring
  to requirements in ASTM F406, Consumer Safety Specification for Non-Full-Size Baby Cribs/Play Yards.

• A reference to requirements in 16 CFR part 1218, Safety Standard for Bassinets and Cradles, to ensure consistency with other
  mandatory requirements in addition to referring to requirements in ASTM F2194.
  This direct final rule maintains these requirements as modifications to ASTM F2933-25, as excluding these requirements would
  be a reduction in safety.

III. Incorporation by Reference

Section 1241.2 of the direct final rule incorporates by reference ASTM F2933-25. The Office of the Federal Register (OFR)
has regulations regarding incorporation by reference. 1 CFR part 51. Under these regulations, agencies must discuss, in the
preamble to a final rule, ways in which the material the agency incorporates by reference is reasonably available to interested
parties, and how interested parties can obtain the material. In addition, the preamble to the final rule must summarize the
material. 1 CFR 51.5(b).

In accordance with the OFR regulations, section I. and II. of this preamble summarizes the major provisions of ASTM F2933-25
that the Commission incorporates by reference into 16 CFR part 1241. The standard is reasonably available to interested parties
in several ways. Until the direct final rule takes effect, a read-only copies of ASTM F2933-25 and ASTM F2194-25 are available
for viewing on ASTM's website at: https://www.astm.org/CPSC.htm. On February 21, 2026, a read-only copy of ASTM F2194-25 will be available for viewing on the ASTM website at: https://www.astm.org/READINGLIBRARY/. Once the rule takes effect, a read-only copy of ASTM F2933-25 will also be available for viewing on the ASTM website at: https://www.astm.org/READINGLIBRARY/. ASTM F406-24 is already available for viewing at this location. Additionally, interested parties can purchase all referenced
ASTM standards from ASTM International, 100 Barr Harbor Drive, P.O. Box C700, West Conshohocken, PA 19428-2959 USA; phone:
(610) 832-9585; www.astm.org. Finally, interested parties can schedule an appointment to inspect a copy of the standard at CPSC's Office of the Secretary,
U.S. Consumer Product Safety Commission, 4330 East-West Highway, Bethesda, MD 20814, telephone: (301) 504-7479; email: cpsc-os@cpsc.gov.

IV. Certification

Section 14(a) of the Consumer Product Safety Act (CPSA; 15 U.S.C. 2051-2089) requires manufacturers, including importers,
of products subject to a consumer product safety rule under the CPSA, or to a similar rule, ban, standard, or regulation under
any other act enforced by the Commission, to certify that the products comply with all applicable CPSC requirements. 15 U.S.C.
2063(a). Such certification must

  be based on a test of each product, or on a reasonable testing program, or, for children's products, on tests of a sufficient
  number of samples by a third party conformity assessment body accredited by CPSC to test according to the applicable requirements.
  As noted, standards issued under section 104(b)(1)(B) of the CPSIA are “consumer product safety standards.” Thus, they are
  subject to the testing and certification requirements of section 14 of the CPSA.

Because crib mattresses are children's products, a CPSC-accepted third party conformity assessment body must test samples
of the products. Products subject to part 1218 also must comply with all other applicable CPSC requirements, such as the lead
content requirements in section 101 of the CPSIA; (5) the phthalates prohibitions in section 108 of the CPSIA (6) and 16 CFR part 1307; the tracking label requirements in section 14(a)(5) of the CPSA; (7) and the consumer registration form requirements in section 104(d) of the CPSIA. (8) ASTM F2933-25 does not make any changes that would impact any of these existing requirements.

V. Notice of Requirements

In accordance with section 14(a)(3)(B)(iv) of the CPSA, the Commission previously published a notice of requirements (NOR)
for accreditation of third party conformity assessment bodies (third party labs) for testing crib mattresses, and codified
the requirement at 16 CFR 1112.15(b)(50). 87 FR 8640 (Feb. 15, 2022). The NOR provided the criteria and process for CPSC to
accept accreditation of third party conformity assessment bodies for testing crib mattresses to 16 CFR part 1241. The NORs
for all mandatory standards for durable infant or toddler products are listed in the Commission's rule, “Requirements Pertaining
to Third Party Conformity Assessment Bodies,” codified in 16 CFR part 1112.

ASTM F2933-25 includes one new test fixture, a “rigid bar,” and adds specifications to the firmness test fixture currently
used in 16 CFR part 1241. The rigid bar can be easily machined, and its use is simply integrated into the firmness test protocol.
The added specifications to the firmness test fixture could cause test laboratories to modify or remake existing test fixtures
to ensure they remain within specification, but the fixture's use is based on the existing test protocol. Accordingly, the
revisions do not significantly change the way that third party conformity assessment bodies test these products for compliance
with the safety standard for crib mattresses. Laboratories will begin testing to the new standard when ASTM F2933-25 goes
into effect, and the existing accreditations that the Commission has accepted for testing to this standard will cover testing
to the revised standard. Therefore, the Commission considers the existing CPSC-accepted laboratories for testing to ASTM F2933-21
to be capable of testing to ASTM F2933-25 as well. Accordingly, the existing NOR for this standard will remain in place, and
CPSC-accepted third party conformity assessment bodies are expected to update the scope of the testing laboratories' accreditations
to reflect the revised standard in the normal course of renewing their accreditations.

VI. Direct Final Rule Process

On December 3, 2025, the Commission provided notice in the
Federal Register
of the revision to the standard and requested comment on whether the revision improves the safety of crib mattresses covered
by the standard. 90 FR 55701. CPSC received four comments. Now, the Commission is issuing this rule as a direct final rule.
Although the Administrative Procedure Act (APA; 5 U.S.C. 551-559) generally requires agencies to provide notice of a rule
and an opportunity for interested parties to comment on it, section 553 of the APA provides an exception when the agency “for
good cause finds” that notice and comment are “impracticable, unnecessary, or contrary to the public interest.” Id. 553(b)(B). The Commission concludes that when it updates a reference to an ASTM standard that the Commission incorporated
by reference under section 104(b) of the CPSIA, notice and comment are not necessary.

The purpose of this direct final rule is to update the reference in the Code of Federal Regulations (CFR) so that it reflects
the version of the standard that takes effect by operation of law. This rule updates the reference in the CFR, but under the
terms of the CPSIA, ASTM F2933-25 would take effect as the new CPSC standard for crib mattresses in the absence of any action
by the Commission. Thus, public comments would not lead to substantive changes to the standard or to the effect of the revised
standard as a consumer product safety rule under section 104(b) of the CPSIA. Under these circumstances, notice and comment
are unnecessary.

In Recommendation 2024-6, the Administrative Conference of the United States (ACUS) endorses direct final rulemaking as an
appropriate procedure to expedite rules that are unlikely to elicit any significant adverse comments. See 89 FR 106406 (Dec. 30, 2024). ACUS recommends that agencies use the direct final rule process when they act under the “unnecessary”
prong of the good cause exemption in 5 U.S.C. 553(b)(B). 89 FR 106406, 106409. ACUS also explains that notice and comment
may be “unnecessary” when the agency lacks discretion regarding the substance of the rule. Id. at 106408. As noted, this rule updates a reference in the CFR to reflect a change that occurs by operation of law. Consistent
with the ACUS recommendation, the Commission is publishing this rule as a direct final rule, because CPSC does not expect
any significant adverse comments.

Unless CPSC receives a significant adverse comment within 30 days of this notification, the rule will become effective on
May 3, 2026. In accordance with ACUS's recommendation, the Commission considers a significant adverse comment to be one where
the commenter explains why the rule would be inappropriate, “including challenges to the rule's underlying premise or approach,”
or where the commenter explains why the rule would be ineffective or unacceptable without change. Id. at 106409. As noted,
this rule updates a reference in the CFR to reflect a change that occurs by statute.

If the Commission receives a significant adverse comment, the Commission will withdraw this direct final rule. Depending on
the comment and other circumstances, the Commission may then incorporate the adverse comment into a subsequent direct final
rule or publish a notice of proposed rulemaking, providing an opportunity for public comment.

VII. Regulatory Flexibility Act

The Regulatory Flexibility Act (RFA; 5 U.S.C. 601-612) generally requires agencies to review proposed and final rules for
their potential economic impact on small entities, including small businesses, and prepare regulatory flexibility analyses.
5 U.S.C. 603, 604. The RFA applies to any rule that is subject to notice and comment procedures under section 553 of the APA. Id. As discussed in section VI. of this preamble, the Commission has determined notice and comment are unnecessary for this rule.
Therefore, the RFA does not apply. CPSC also notes the limited nature of this document, which updates the incorporation by
reference to reflect the mandatory CPSC standard that takes effect under section 104 of the CPSIA by operation of law.

VIII. Paperwork Reduction Act

The current mandatory standard for crib mattresses includes requirements for marking, labeling, and instructional literature
that constitute a “collection of information,” as defined in the Paperwork Reduction Act (PRA; 44 U.S.C. 3501-3521). The Commission
took the steps required by the PRA for information collections when it promulgated 16 CFR part 1241, and the marking, labeling,
and instructional literature for crib mattresses are currently approved under OMB Control Number 3041-0159. The revision does
not affect the information collection requirements or approval related to the standard.

IX. Environmental Considerations

The Commission's regulations provide for a categorical exclusion from any requirement to prepare an environmental assessment
or an environmental impact statement where they “have little or no potential for affecting the human environment.” 16 CFR
1021.5(c)(2). This rule falls within the categorical exclusion, so no environmental assessment or environmental impact statement
is required.

X. Preemption

Section 26(a) of the CPSA provides that where a consumer product safety standard is in effect and applies to a product, no
state or political subdivision of a state may either establish or continue in effect a requirement dealing with the same risk
of injury unless the state requirement is identical to the Federal standard. 15 U.S.C. 2075(a). Section 26(c) of the CPSA
also provides that states or political subdivisions of states may apply to CPSC for an exemption from this preemption under
certain circumstances. Section 104(b) of the CPSIA deems rules issued under that provision “consumer product safety standards.”
Therefore, once a rule issued under section 104 of the CPSIA takes effect, it will preempt in accordance with section 26(a)
of the CPSA.

XI. Effective Date

Under the procedure set forth in section 104(b)(4)(B) of the CPSIA, when a voluntary standards organization revises a standard
that the Commission adopted as a mandatory standard, the revision becomes the CPSC standard 180 days after notification to
the Commission, unless the Commission determines that the revision does not improve the safety of the product, or the Commission
sets a later date in the
Federal Register
. 15 U.S.C. 2056a(b)(4)(B). The Commission is taking neither of those actions with respect to the revised standard for crib
mattresses. Therefore, ASTM F2933-25 automatically will take effect as the new mandatory standard, with some retained modifications,
for crib mattresses on May 3, 2026, 180 days after the Commission received notice of the revision. As a direct final rule,
unless the Commission receives a significant adverse comment within 30 days of this notice, the rule will become effective
on May 3, 2026, and will apply to products manufactured after the rule's effective date.

XII. Congressional Review Act and Executive Order 12866

Pursuant to the Congressional Review Act (CRA) and Executive Order (E.O.) 12866, the Office of Management and Budget's Office
of Information and Regulatory Affairs has determined that this rule does not qualify as a “major rule,” as defined in 5 U.S.C.
804(2), and is not a significant regulatory action as defined under section 2(f) of E.O. 12866. To comply with the CRA, CPSC
will submit the required information to each House of Congress and the Comptroller General.

List of Subjects in 16 CFR Part 1241

This paragraph applies only to a play yard mattress that is interchangeably used as a play yard mattress and as a bassinet
mattress/pad. (See 16 CFR part 1218 for the Safety Standard for Bassinets and Cradles.)

(4) Renumber section 6.2.2 of ASTM F2933-25 to section 6.2.3.

5/8
in. ±
1/8
in. (727 mm ± 3.2 mm) from Wall D, as shown in Fig. 12. The mattress shall not be moved during measurement. This shall be
the corner gap measurement.
