Crib Safety Standards: What Current Rules Cover

By Graham Fisher

Crib safety standards in the United States changed dramatically in 2011, and understanding what those rules cover helps parents and caregivers choose a sleep space with confidence. The U.S. Consumer Product Safety Commission (CPSC) updated federal crib rules for the first time in nearly 30 years, targeting the hazards that had led to millions of recalls and dozens of infant deaths. Whether you are buying a new crib, inspecting a hand-me-down, or checking the crib at a child care facility, knowing the current requirements is the first step toward a safer nursery.

What the Federal Crib Safety Standards Cover

According to a CPSC news release from December 2010, the agency voted unanimously to approve new mandatory standards for full-size and non-full-size baby cribs. The rules took effect in June 2011 and apply to any crib manufactured, sold, or leased in the United States. The CPSC’s cribs standards page states that the new requirements were designed to stop the manufacture and sale of traditional drop-side cribs, make mattress supports stronger, make crib hardware more durable, and make safety checks more rigorous.

The CPSC news release notes that the agency had recalled more than 11 million dangerous cribs since 2007. Detaching drop-side rails were associated with at least 32 infant suffocation and strangulation deaths since 2000, and additional deaths occurred because of faulty or defective hardware. The new standards adopted the current ASTM International voluntary standards with additional technical modifications, the CPSC explains. Child care facilities, such as family child care homes and infant Head Start centers, and places of public accommodation like hotels and motels, were required to have compliant cribs within 24 months after the rule was published.

Because the standards cover both full-size and non-full-size cribs, any crib you buy new today should meet these federal requirements. If you are considering a convertible crib or a mini crib, the same mandatory rules apply. The CPSC’s crib information center offers additional details on the standards and safe sleep environments.

How to Check Any Crib for Safety

Nemours KidsHealth provides a practical checklist for parents inspecting a crib, whether it is brand new, a hand-me-down, or one used at daycare or a relative’s home. The guidance starts with a simple rule: make sure the crib was made after 2011 so that it meets the most current safety requirements. Next, measure the distance between slats. KidsHealth says the slats should be no more than 2-3/8 inches (6 centimeters) apart and should not be cracked, loose, splintered, or missing.

Look at the headboard and footboard. There should be no decorative cutouts where a baby could become caught, and no sharp or jagged edges. The sides must not drop. All screws should be present and none should be sticking out. Tightly attached corner posts should be no more than 1/16 inch (1.5 millimeters) high, according to KidsHealth’s crib safety article. In a separate guide on choosing safe baby products, KidsHealth adds that if corner posts are present, they must be either flush with the top of the headboard and footboard or very tall, over 16 inches (41 centimeters). Anything in between is a potential strangulation hazard.

Inside the crib, the mattress matters. KidsHealth advises using the firmest mattress you can find and checking it yourself by pushing firmly on the center and all sides; it should hold firm and spring back quickly. The mattress must fit snugly against the crib sides with no large gaps. If your child can stand, the mattress should be in its lowest position. The crib sheet should fit the mattress snugly, and you should never use an adult sheet.

For used cribs, KidsHealth recommends extra caution. Avoid cribs older than 10 years because they may not meet the most recent safety standards. There may be too much space between slats or decorative cutouts that can trap a baby’s head. A crib made before 1978 could have a finish that contains lead. Always check that all hardware is present and that slats and parts are in good condition. Only use manufacturer-provided parts if repairs are needed, and make sure you have the manual to assemble the crib properly.

Safe Sleep Inside the Crib: Bare Is Best

Once the crib itself meets the standards, what you put inside it is just as important. The CPSC’s “Bare Is Best” guidance states that parents should always place baby on their back to sleep and use a crib that meets current CPSC standards. Keep pillows, quilts, comforters, and cushions out of the crib, bassinet, or play yard. Use a firm, tight-fitting mattress. Positioning devices are unnecessary and can be deadly. For warmth, dress baby in footed pajamas.

The CPSC notes that nearly half of the infant crib deaths and two-thirds of bassinet deaths reported to the agency each year are suffocations from a baby being placed on top of pillows and thick quilts or because of overcrowding in the sleep environment. KidsHealth echoes this with its “bare bed is best” advice: no bumper pads, soft bedding, or soft toys such as blankets, fluffy comforters, pillows, or plush toys. Remove bibs and necklaces before putting your baby in the crib, and do not hang toys by strings. Mobiles should be taken down when your baby starts pushing up on hands and knees, or by age 5 months, whichever comes first.

Also check the area around the crib. KidsHealth warns that no cords from drapes or window shades should be anywhere near the crib or within the baby’s reach. For more on keeping cords away from sleep spaces, see our article on baby monitor placement and cord safety.

Crib Safety Rules at a Glance

These rules apply to full-size cribs, non-full-size cribs, and mini cribs. If you are furnishing a nursery, also consider securing furniture to the wall; our guide to furniture anchors and tip-over prevention explains how to reduce that risk.

Frequently asked questions

Do all cribs sold today meet the current safety standards?

According to the CPSC, cribs manufactured, sold, or leased in the United States since June 2011 must comply with the new federal standards. Any new crib you purchase from a retailer should meet those requirements. If you are unsure, check the CPSC website for recalls and verify the manufacture date.

Can I use a hand-me-down crib?

KidsHealth advises checking that the crib was made after 2011, has no drop-side rail, and has slats no more than 2-3/8 inches apart with no decorative cutouts. All hardware should be present and in good condition. Avoid cribs older than 10 years and those made before 1978, which may contain lead paint. Only use manufacturer-provided parts for any repairs, and make sure you have the assembly manual.

What should I put in the crib with my baby?

The CPSC says bare is best. Place your baby on their back on a firm, tight-fitting mattress with a snug crib sheet. Do not add pillows, quilts, comforters, cushions, bumpers, or soft toys. For warmth, dress your baby in footed pajamas. If you have questions about safe sleep practices, ask your pediatrician.
