Baby crib regulations in the United States are set by the Consumer Product Safety Commission and cover how a crib is built, what it can be made of, how it must be tested, and what cannot be sold alongside it. The core rules sit in 16 CFR Parts 1219 and 1220, with related standards for play yards and crib mattresses, and a 2022 statute that bans padded crib bumpers and inclined infant sleepers outright. Any crib sold, leased, donated through commerce, or provided in a hotel or daycare has to meet the current standard.
The Rules That Apply to a Crib
The Consumer Product Safety Improvement Act of 2008 gave the CPSC authority to write mandatory safety standards for durable infant products.1U.S. Consumer Product Safety Commission. The Consumer Product Safety Improvement Act Before that law, crib standards were voluntary. The mandatory rules the CPSC issued took effect in 2011 and remain the baseline today.2eCFR. 16 CFR 1219.1 – Scope, Compliance Dates, and Definitions
Two regulations do most of the work. 16 CFR Part 1219 covers full-size baby cribs, and 16 CFR Part 1220 covers non-full-size cribs. Each incorporates a detailed ASTM engineering standard with additional CPSC modifications; full-size cribs, for example, must meet ASTM F1169-19.3eCFR. 16 CFR 1219.2 Play yards fall under 16 CFR Part 1221, and crib mattresses have their own standard at 16 CFR Part 1241.
How a Compliant Crib Has to Be Built
No Drop Sides
Traditional drop-side cribs, whose movable rail slid down to make lifting a baby easier, are banned. The hardware holding those rails was prone to breaking or loosening, and a detached rail could create a gap where an infant became trapped.4U.S. Consumer Product Safety Commission. CPSC Approves Strong New Crib Safety Standards To Ensure a Safe Sleep for Babies and Toddlers All four sides of a compliant crib are permanently fixed.
Slat Spacing
The gap between slats, spindles, or rods can be no more than 2⅜ inches, a measurement chosen to prevent an infant’s head from passing through. Under 20 pounds of direct pressure, that gap cannot open wider than 2½ inches.5eCFR. 16 CFR Part 1219 – Safety Standard for Full-Size Baby Cribs
Rail Height
The top of the side rail must be at least 26 inches above the mattress support at its lowest setting. When the mattress support is raised to its highest position, the rail still needs to sit at least 9 inches above it. Both measurements matter, because most cribs let you lower the support as your child grows.
Mattress Fit
A full-size crib’s interior is tightly specified: 28 inches wide and 52⅜ inches long, each with only ⅝ inch of tolerance. A standard full-size crib mattress is built to fit with almost no room to spare. If you can slide more than two fingers between the mattress and the crib side, the mattress is too small for that crib and needs to be replaced.
Corner Posts
Corner posts sit essentially flush with the top of the side or end panel. Anything taller creates a snag hazard for clothing that can lead to strangulation. The one exception is a corner post tall enough to serve as a canopy support, which follows its own height rules.
Chemical Limits on Materials
Three separate limits govern what a crib can be made of:
- Any surface coating containing 0.009 percent or more lead by weight (90 parts per million) is a banned hazardous substance.6U.S. Consumer Product Safety Commission. Lead in Paint
- Any accessible component containing more than 100 parts per million of total lead is also banned. That covers metal hardware, plastic parts, and anything a child could touch or mouth.7CPSC.gov. Total Lead Content
- Children’s products cannot contain more than 0.1 percent of several specific phthalates, including DEHP, DBP, BBP, DINP, and DIBP.8eCFR. 16 CFR 1308.1 – Prohibited Children’s Toys and Child Care Articles
Hardware itself has to survive rigorous use-and-abuse testing meant to simulate years of normal wear, and must include anti-loosening features so that screws and fasteners do not back out over time.
Products That Can No Longer Be Sold
The Safe Sleep for Babies Act, signed into law on May 16, 2022, made two categories of products illegal to sell, manufacture, or import, regardless of when they were made.9U.S. Consumer Product Safety Commission. Safe Sleep for Babies Act Business Guidance
Crib bumpers are covered, including padded bumpers, vinyl bumper guards (supported or unsupported), and vertical slat covers. Non-padded mesh liners are not part of the ban. Inclined sleepers are also covered: any product with a sleep surface angled more than 10 degrees, designed for infants up to one year old. Rockers, gliders, and swings that recline beyond 10 degrees are not sleep products at all, even for supervised naps. If you still own either type of product, do not use it, sell it, or give it away.
Federal safe-sleep guidance is that a fitted sheet is the only thing that belongs on a crib mattress.10U.S. Consumer Product Safety Commission. Safe Sleep – Cribs and Infant Products No pillows, blankets, weighted swaddles, stuffed animals, or sleep positioners.
Play Yards and Crib Mattresses
A play yard sold as a sleep space has to meet 16 CFR Part 1221, which incorporates ASTM F406-24 and covers folding mechanisms, locking hardware, mesh side panels, and the floor pad.11eCFR. 16 CFR Part 1221 – Safety Standard for Play Yards Use only the mattress pad that came with the play yard, or an aftermarket pad the manufacturer specifically lists for that model. Anything else can leave gaps.
Crib mattresses have their own standard under 16 CFR Part 1241, which includes a firmness test aimed at reducing the risk of suffocation on a surface that conforms to a baby’s face.12eCFR. 16 CFR Part 1241 – Safety Standard for Crib Mattresses
How to Tell If a Specific Crib Complies
Every crib sold in the U.S. has to be tested by a CPSC-accepted independent laboratory and come with a Children’s Product Certificate. The CPC must identify the product, list every safety rule it was tested against, give the manufacturer’s name and contact information, and record the date and location of manufacturing and testing.13U.S. Consumer Product Safety Commission. Children’s Product Certificate
A permanent tracking label also has to be affixed to the crib itself. It shows the manufacturer or importer, the production date and location, and a batch or run identifier that ties the crib back to its source.14U.S. Consumer Product Safety Commission. Tracking Label Requirements That label is what makes recalls workable. Without it, there is no way to tell whether a specific crib belongs to a recalled batch.
Before using a crib you already own, look up the tracking-label information in the CPSC recall database at cpsc.gov/Recalls, which lets you filter by the Cribs category.15U.S. Consumer Product Safety Commission. Recalls and Product Safety Warnings A recall notice will describe the hazard and lay out the remedy, usually a refund, replacement, or free repair kit.16U.S. Consumer Product Safety Commission. How to Conduct a Recall
Secondhand Cribs, Daycares, and Hotels
Any business that sells, rents, or provides a crib for use has to make sure it meets the current federal standard. That includes thrift stores, consignment shops, hotels, daycare centers, and family childcare homes.2eCFR. 16 CFR 1219.1 – Scope, Compliance Dates, and Definitions The CPSC’s guidance to resellers is direct: destroy any crib manufactured before June 28, 2011, rather than resell it, unless there is written proof the specific crib meets the current standard. For cribs made after that date, fully assemble the crib and confirm all parts and hardware are present before offering it.17U.S. Consumer Product Safety Commission. Full-Size Baby Cribs – Business Guidance FAQ
Private sales between individuals are not covered by the federal prohibition, but the CPSC advises against using older or antique cribs at all. Many pre-2011 cribs fail modern slat-strength, hardware-durability, and structural requirements even when they look fine. If you are throwing out a non-compliant crib, take it apart first so nobody else can pick it up and use it.
Reporting a Problem
If a crib seems unsafe or a child has been injured, report it through SaferProducts.gov. These reports become public and feed the CPSC’s decisions about when to investigate and whether to open a recall. The more specific the report, the more useful it is: include the tracking-label details, the model, and what happened.
