Crib Mattresses: Head-to-Head Comparisons
America's most-shopped cribs, compared honestly. Conversion stages, materials and certifications come from each manufacturer's own product pages — never retailer listings — every model carries a dated CPSC recall check, and every page keeps AAP-aligned safe-sleep context front and center.

Safety notes
- Buy new, or check recalls first. Crib mattresses sold legally in the US must meet federal flammability standards 16 CFR Part 1632 (cigarette smolder) and 16 CFR Part 1633 (open flame). Buy from a current retailer, cross-check any second-hand mattress against the CPSC recall list, and confirm a snug fit — no gaps wider than two fingers at the edges.
- Fixed sides only. All cribs we compare are fixed-side designs. Never modify a crib or improvise missing parts.
- Mattress fit matters. Use a firm, flat mattress that fits with no more than two fingers of gap at the edges — all cribs compared here take a standard full-size crib mattress (52″ × 28″ interior).
- Keep the sleep surface bare. Per AAP guidance: firm flat surface, nothing soft or loose in the crib, room-share without bed-share, and move your child out once they're about 35 inches tall or can climb.
- register your mattress for recall notices. Manufacturer registration is how recall notices reach you — it takes two minutes with the card in the box.
- Certifications, honestly framed. GREENGUARD Gold means a product was tested for low chemical emissions; it's an air-quality standard, not a crash or injury rating — no crib is officially "safer" than another that meets the same federal rule.
