Overview
This is Naturepedic's 2-stage organic crib mattress, made with a GOTS certified organic cotton cover and a lightweight wave-support core that keeps the whole mattress under 11 lbs for easier sheet changes.
The organic cotton cover is finished with a sugarcane-derived waterproof coating instead of vinyl, so it can be wiped clean without introducing phthalates. It ships compressed and needs time to fully expand, and buyers describe it as noticeably firmer than typical crib mattresses, which lines up with the pediatric firm-sleep guidance it's built around.
- Standard size 27 1/4 in x 51 5/8 in x 6 in
- GOTS, UL, and Greenguard certified
- Weighs about 11 lbs
- Sugarcane-derived waterproof coating
Who it's for
Parents prioritizing an organic, low-emission mattress for a newborn's crib, especially those switching from a softer mattress and willing to let a toddler adjust to the firmer feel. Less suited to anyone expecting a plush toddler mattress.
Pros and cons
- GOTS certified organic cotton cover
- Lightweight core, under 11 lbs, for easier sheet changes
- Waterproof coating without vinyl or phthalates
- Lifetime warranty backed replacements
Performance notes
The 2-stage design keeps support flat and firm for infant sleep safety, while the wave-support core inside keeps total weight low. The waterproof coating sits on top of the organic cotton rather than replacing it with vinyl, so the surface stays breathable while still wiping clean.
