Nestig x Lullaby Earth Breathe Safe Mini Mattress

$64.5 ~~$129~~ In stock

While each of our mini-cribs comes with a standard mattress, we've partnered with Lullaby Earth to create a certified non-toxic mattress custom-made for our cribs that comes with a waterproof, breathable cover for extra peace of mind.

The design consists of a certified non-toxic mattress wrapped in a removable, washable, breathable cover with a waterproof backing. It is non-toxic, hygienic, convenient and supportive—everything you’re looking for in a safer crib mattress.

I was worried about finding a safe mattress that actually fits my crib, but this one clicked right into place and feels firm yet comfortable. The waterproof cover is a lifesaver for middle-of-the-night accidents, and knowing it's certified non-toxic gives me real peace of mind.

Fitting it into my mini-crib was seamless, and I love that this mattress is both certified non-toxic and waterproof—a huge relief for those inevitable spills.

The waterproof layer gives me peace of mind, and it fits perfectly in the mini-crib without any gaps. My baby seems to sleep more soundly on this certified non-toxic surface.
