Ratings & Reviews+

Sealy Baby Ultra Rest crib mattress is rated 4.6667 out of 5 by 12.
Rated 5 out of 5 by from Perfect Mattress This is one of the best mattresses that I have ever purchased. Super firm, waterproof, fits the crib snuggly and handles all the jumping that my girls do several times a day in their cribs. Very happy with my purchase.

Rated 5 out of 5 by from excellent value for money! we bought this mattress for our 2 year old and its great. a bit more firm than we thought it would be but still provides a great sleep for our boy. more springs for less money than other baby stores.

Rated 4 out of 5 by from excllent quality mattress I researched mattresses before buying, and this is the one that best met my needs. I needed one that would work with an angel care monitor, and only a standard mattress (vs a 2 in 1) is recommended. Nice touch that it's also waterproof. I took off onr start because it took an extra 2 weeks to receive than given when ordered.

Rated 4 out of 5 by from Feels sturdy We both this a month ago to replace the 2.5 year old crib mattress we got when our daughter was born. The old mattress was dented and squished. The new one seems really sturdy and I'm hoping it lasts alot longer then 2.5 years like the old one

Rated 5 out of 5 by from Great Mattress! I bought this crib mattress about a month ago and it came earlier than expected and defiantly met my expectations. With the specifications on what to look for when buying a crib mattress, i would recommend this one!
