Sealy Waterproof Ultra Firm Standard Crib & Toddler Mattress Wmt, 52" X 28"

Our son moved from his crib to his Thomas bed. His crib mattress was too small and it was uncomfortable. This mattress fit it perfectly and is super 👌 comfortable. It made the transition easy, very unexpected.

This mattress + cover would have worked perfectly fine, but one of the seams on the cover "popped" before the mattress was even inside the cover. It does not even appear to have been sewn, just adhesive glued in place. Of course the seam that popped is the one that allows the zipper to close fully, and without it the zipper pull fell right off - which means even if you still used it, the zipper could pop open at any time and you'd have to wrestle to get the zipper pull lined up and back onto the zipper.I would have returned it without leaving a review, but it needs to be back in the box to return - and anyone who has opened a foam mattress knows you can't get those suckers flattened down enough to re-pack...

Decent for the price. Pretty basic. It is supposed to be two-sided and marked infant with arrows so you know which side is which, however it wasn’t and it’s just a big block of them I don’t even know if the two sides are different.
