Review

What to know about Babyletto Pure Core Crib Mattress w/ Dry Waterproof Cover (2-Stage)

A lightweight (12 lb), foam-free and vinyl-free mattress with a polyester core, an organic cotton cover over modacrylic batting, and a polyethylene waterproof layer. BabyGearLab gave it its value award and found it firm. It is oversized (52.4 x 28.4 in), so it fits snugly.

Editorial notes

Why it stands out

Why we like it

It is the cheapest pick here and is sold directly by Amazon. BabyGearLab's review, dated April 2025, confirms an organic cotton top and bottom, a polyester core, a polyethylene waterproof layer, and no PVC, vinyl or phthalates. It is GREENGUARD Gold certified and weighs 12 lb.

The fire barrier is modacrylic batting, an inherently flame-resistant fiber that is partly made from vinyl chloride. Babyletto says it uses no added chemical flame retardants. Strict non-toxic shoppers may want to weigh that.

What to know

Skip it if the modacrylic fire barrier bothers you, or if you want a true two-firmness mattress. BabyGearLab found the same firmness on both sides.
