Our little guy sleeps so soundly

Watching our baby sleep peacefully is such a gift. This mattress feels firm and supportive without being hard. He settles in so well, and that gives us time to rest too

From registry to real life

We added it to our registry kind of on a whim, and now I tell all my pregnant friends to get one. It’s been such a great first mattress. Durable, easy to clean, and baby approved

Easy on the wallet

We didn’t want to spend a fortune for a second crib setup, but we still wanted something safe and comfy. This hit the sweet spot

Best children’s mattress

When looking for a mattress for our first baby, I was nervous. You hear horror stories about EVERYTHING. After reading reviews, I bit the bullet and I am SO glad I did. It’s the perfect mix of soft and firm for our baby.

Best Mini Crib Matttess

We ordered this to use with our Delta Children mini crib and it's the perfect fit! I was so happy with the feel of this mattress. After moving from a bassinet, this gave our girl the perfect space and comfort. It's firm but not like a board and keeps her cozy while she sleeps for 11-12 hrs. So glad we got it!

Great little mattress

I am glad I bought this mini crib mattress to replace the one that already comes with the crib. It’s really firm and perfect if your little one is a little older for that extra cushion and firmness.

Love it!

I love the mattress. It’s very lightweight, very soft but not too firm and I love that it’s waterproof which will make it easier to clean up if my baby has any accidents. My toddler loves it and I can’t wait to use it for my newborn baby soon.

Dreamy Quality

LOVE this mattress for our babe! Our mini crib included a mattress, but we wanted something a little more comfortable. This is definitely it! It’s more than twice the size of the other mattress, & feels much more durable. It’s firm, yet soft. The water proof protection is a huge bonus! Love this little Serta mattress!
