A pale oak crib with rounded corners and vertical slats standing on a cream textured rug in a daylit nursery. A matching oak dresser with a round mirror and a vase of pampas grass sits behind it, sheer linen curtains hang at the window, and a grey upholstered glider with a folded cream throw and a stack of board books sits to the left. — Illustrative photo: a slatted wooden crib in a daylit nursery.

Baby Gear Safety, Decoded from the Source

Last updated: July 30, 2026

Crib Lab explains baby-gear safety by citing the actual standard behind it — CPSC regulations (16 CFR), NHTSA guidance, FMVSS 213, ASTM specifications, JPMA certification, and AAP published recommendations — not marketing copy. Every safety claim on this site links to its regulator or standards-body source. We do not give medical, sleep-training, or improvised safety advice, and we never recommend secondhand car seats or cribs.

"Meets safety standards" on a box tells you almost nothing without the standard's number and what it actually tests. A crib slat gap has a hard federal limit — 2 3/8 inches, set by 16 CFR Part 1219. A car seat's LATCH lower anchors have a combined-weight cutoff (65 lb). FMVSS 213 is the crash-test standard every car seat must pass — but it doesn't tell you when to switch from rear-facing. Start with Buying Baby Gear on Amazon The Baby Gear Safety Numbers, our full cited reference table, or pick a gear category below.

Always follow your product's manual and current CPSC/NHTSA guidance — this site summarizes published standards and is not a substitute for them.

Shop by the standard, not by the star rating

We don't name specific models. Certification is granted to a configuration, and a listing can change what it ships without changing its title — so a "best crib" pick can quietly stop being the thing that was reviewed. What doesn't change is the standard each class has to meet. Read the guide first, then search the category with those numbers in hand.
