Key Features

CertiPUR‑US® Foam Core: Independently tested foam meets strict content, emissions, and durability standards, delivering consistent crib‑safe firmness without ozone depleters, PBDEs, mercury, lead, or formaldehyde.
Breathable, VOC‑Free Interior: Engineered with breathable covers and VOC‑free polyester components to encourage air circulation and a fresher sleep space, supporting comfortable temperatures through naps and overnight sleep.
Chemical‑Free Cotton Cover: Soft, natural cotton cover is free from harmful chemical treatments for a cleaner surface next to baby’s skin, helping create a healthier nursery with simple, quiet comfort.
Quiet, Noiseless Design: A stable foam core and fabric layers eliminate crinkle noises, so movements stay hushed and overnight changes won’t startle light sleepers or wake siblings.
