One side of the width barely puffed up and one side of the length didn't as much as the rest of the bed. I let it sit out for 48 hours hoping it would change. Wish it was an inch or 2 thicker too. It's better than those basic matteress that make noises and crack.

The package the crib arrived in was badly damaged. I gave the crib as a gift, hopping that the crib inside was sufficiently protected to prevent any damage. I've never had an experience like this with Walmart before. The mattress arrived in perfect condition.

I purchased two of these for my large (85 lbs) dogs, because "real" dog beds for large dogs are very expensive. I covered the top and bottom with crib sheets and put a waterproof mattress pad under the top sheet. The mattress is firm enough that my dogs' weight barely even makes a dent in it, yet it is soft enough to be comfortable. When my son saw them, he wanted one for his soon-to-arrive baby. I can see that these would be much better than the plastic-encased spring-coiled mattress that I used for my children. The creaking and crinkling always woke them up. For anyone concerned that the memory foam would be a smother hazard for babies, I would say that the mattress is so firm that I would have no worries about that. The mattress was encased in three different covers. The one closest to the mattress is silky and thin, like parachute material, and one of them tore while I was removing it. This one also had a lot of loose threads that I cut off. The zipper also came off the first time I took it off. These were the only negatives I saw. All three covers fit perfectly and were easy to take off/put on while still being snug. When the mattress arrives, you should definitely take off all the covers so that the mattress will expand evenly (saw this tip from another reviewer). Otherwise, the corners tend to remain squished a little.

I bought this mattress because my 14 month old hated her bed so I thought it might be her mattress. We have a foam mattress so i figured I would get one for her too. She loves it! It is firm yet comfortable!! As soon as she saw it she climbed on top and layed down. It is shipped in the original box so everyone can see what it is, not that it was a problem for me. It is all wrapped in plastic and was easy to get out. Let it sit for 2 days before using it. It plumped up good. Glad we got this one!!!

This bed is everything that I wanted for my daughter. Firm but still soft and doesnt have plastic so it dont make a sound as she gets in and out her bed or toss throughout the night. I love it and need to buy another one!! If they had one in King and this cheap I would purchase it without a doubt!

I wanted to purchase a mattress that was soft and not so hard because I didn't want him to be jumping to my bed later because he didn't like his bed. It's perfect, he loves it! It's soft but at the same time has a good Comfort. Great price. I got it on sale!

Got this for my baby his sisters love to sleep in his bed they say it's much comfortable than there's even though they have a memory foam mattress but maybe it's just because they want to sleep in our room. Regardless of the reason they all feel comfortable in his bed including my baby highly recommend it does expand as well.

Comes compact in box already in the covers. But if you want a 5 in Mattress as it states, not a 4 in thick Topper, get something else. Instructions say let puff up for 48 hours to reach full size. After a week it has only gone to 4 inches so that is very disappointing. So tired of not getting what was paid for.

Mattress came in a very small box easy to carry. I was a little iffy at first . I received it before my son's toddler bed so I read the reviews I opened and let it expand. I didn't have to push it or anything to expand. It's so comfy my son sleeps all night no problems.

This mattress does not materialize into the picture. A lot fo the reviews you read are pet owners of large dogs who bought this for those dogs. If that is the case for you then it is a great buy. If this for a child, it absolutely is a waste of money. Trying to re-package and send back is a hassle so I gave it to a shelter for a senior dog to have a soft place to sleep.
