Excellent choice!
My 2 year old daughters birthday she got a Grace toddler bed, Sealy Baby Cozy Cool mattress, and Peppa Pig bedding set. She loves it! And runs to get in her bed at bedtime. She sleep way better than when she was in a crib. And sleeps through the night. Great mattress. Highly recommended. Comfy, firm enough, and quiet.

Comfortable but safe
Comfortable but safeIt seemed that my infant daughter preferred to fall asleep on my mattress. For safety reasons, I didn’t want this to continue but I wanted her to have a mattress that was much more plush and soft for her and her bassinet. This seems to be a great balance between comfort and safety. She sleeps really well but the mattress is definitely firm enough that it provides her with safe support.I would recommend this product and I would order it again

Colchón para bebés grandes
Excelente calidad, no es pesado y es muy acolchonado. Ayuda al descanso del bebé y sobre todo a soportar el sudor al dormir.

Baby Approved
We have used this mattress for both of our baby girls and we have no regrets. It is double sided, which we just recently discovered. One side is more suitable for the infant stage and provides a firmer, flatter surface, whereas the other side is more suitable for toddlers with a gel layer for added comfort. Nice that it grows with your baby! Definitely recommend.

Water resistant, not waterproof...
It looks like a beautiful, comfortable mattress. But I really wanted something waterproof like it says in multiple areas of the Amazon description.I called Sealy/Kolcraft, it is water resistant. The rep said if you wipe it right away it will be ok but if liquid is left on it for a long time then liquid will seep through. (She did not specify how long “long time” is.). Babies drool, pee, poop, and spill water... I prefer not to wash a sheet and mattress protector every time. Very disappointing that the Amazon description says “waterproof” in multiple places. But when I received it, the actual label says “ water and stain resistant.” I don’t want to deal with a mattress protector (TPU layer is low dry or air dry, and we wanted to avoid vinyl). Our first has a waterproof mattress (Naturepedic) so I know they exist.If you dont require true waterproof then it’s probably a great mattress.

My child loves this mattress
My newborn is 6 days old and refuses to sleep in the bassinet, but has been more than happy to sleep on this mattress! I can not speak to the longevity or durability of this mattress, as my child is less than a week old; but I can say is my child sleeps soundly on it.

Perfect for our infant
We love this mattress. It’s nice that you can flip it from infant side to toddler side. For the folks who said it sunk in on their infant, it was too hard for their older child it sounds like they didn’t make sure they had the right side for the age. My infant sleeps perfectly on this, it fits the crib perfectly, and doesn’t make her sweaty.
