LOVE this mattress! It took a little less then the 48 hours to completely Expand. I did rotate the mattress to help with the process. Once completely expanded I put all the covers back on. My daughter loves sleeping in her bed now! I even slept in the bed with her and slept like a baby!

The only reason I'm giving this 4 stars is that the first box, which was picked up using site-to-store, seemed to have been opened. When I got home, I discovered that the fire protectant mattress cover was missing from the box. (The only reason I noticed was because I had ordered a second mattress shipped to my house that included the cover. The instructions were included in the packaging of the mattress cover that was missing.) I called walmart.com and was offered several options to remedy the situation. They quickly placed an order for another mattress to be sent. Hopefully it will get here quickly! My children love this mattress as it is almost like sleeping in my bed. It seems to be much more comfortable and it is definitely quieter!

[This review was collected as part of a promotion.] We are expecting our baby boy in January and this mattress is going to be so amazing for him! I couldn’t be happier with the comfortable feeling of it, how soft it is, and how convenient the packaging was. You just unroll it out of the box and it forms together quickly. It’s a great value! Also, the cover is waterproof and comes off to wash. This is the perfect mattress for your crib!

We bought this mattress based on the stellar reviews and will not be using it. We opened the mattress from the box and let it sit out for 3 days prior to placing in the crib. There's a distinct smell, almost potent, that I wasn't expecting for a Green Guard Certified product. It's been out for over 2 weeks and the smell is still very strong, rubbing off onto my baby's skin each morning. It's deep within the mattress and even putting it outside for a few hours a day doesn't get rid of it. I was also disappointed in how soft this mattress is. I thought it would be two sided based on 'crib and toddler' mattress but it is not. I ended up buying another mattress as I simply do not trust this mattress for my baby.

I've been looking for a foam bed for my toddler and I couldn't believe how reasonable this bed was. For the price! I am impressed. I love the brand Graco and this was my first time getting one of their mattresses. It took about 2 days to fully expand. My son loves it! (The photos were taken when I first opened it)

I waited a week for the mattress to plump up (says 48 hours). I took all covers off of it and tried to massage it, turn it different ways, etc. but half of it stayed about an inch thick and only one side expanded. Highly disappointed. Will be returning it.

[This review was collected as part of a promotion.] We are expecting our first baby and just received this amazing mattress and couldn’t be happier with it. It’s so soft and high quality! Great thing that we can use it until our baby girl is a toddler, so, totally worth it. And the cover is waterproof and you can easily take it off to wash, such a great feature! We are glad Storkcraft gave us this great mattress We are recommending to our friends for sure!!

[This review was collected as part of a promotion.] I received this mattress within two days of placing my order. It arrived well packaged and expanded fully within a day. I love that it has a zipper waterproof cover making for easy washing. I think it will provide safe and comfy sleep for my little one.

Has good support, yet is very comfy for my 21 month old grandson. He falls asleep quickly and sleeps contentedly through the night. My one dislike is that it's not as thick as I'd hoped - more like 4 1/2", so crib sheets don't tend to stay smooth and tight, but since he's not a newborn it's not really too bad - just annoys me!

Absolutely love this mattress. We had a vinyl mattress before and it was so noisy the second we laid our daughter down she would wake up. She loves this one and sleeps all night on it. I unrolled perfectly and I couldn't be happier with the quality. It fits snuggly in her toddler bed. It is firm but not overly so. Highly recommend.
