It was a struggle to get this out of the box, very tightly packed. Once I finally got it out of the box, I was surprised at how thin it was, maybe half an inch. I thought no way will that go to 8 inches!! Well to my surprise within only a couple of hours it was already up to 7 1/2 inches. I could have slept on it but decided to wait and go by the directions. Overnight it did raise to the full 8 inches. It is extremely comfortable. I purchased it to use with the Victoria metal daybed and it fit perfectly. I am very satisfied and recommend it .

8 in memory foam mattress
I bought the 8 in firm mattress and it grew to the right size pretty quickly. Cannot believe this is really memory foam. It feels like I'm sleeping on a brick. I have to buy a memory foam mattress topper now. Very disappointed. Theres no way to check if its memory foam as it is covered and I would have to cut the cover to check it.

Awesome mattress

This is a great mattress, the price is very reasonable also. I bought a couple of this for my grandkids age 15 and 13, they love them, they are so comfortable and i would recommend them highly! This is a pic of when they first unwrapped the first mattress, i sure got a kick out of it.

Unreal for the price it's unbelievable !

As some have said in the reviews they had bought in the past very expensive mattresses and never thought this would size up to any of them BUT I am one of those people that in the past paid almost 8 times the price of this one for what I think is the same mattress or at least it sure feels like it ... I left mine set on top of my bed for the full 48hours ( crazy that they can do what they do to these things and put it into that lil box) but it was in it's full shape actually in a couple of hours but I waited and oh was it worth the wait ... felt as good as the old mattress of $$$$ ... I am so glad I stumbled upon Walmart selling such ... had no idea they sold mattresses ... learned a good one here ... always will in the future check with Walmart first ... unless you want to look elsewhere first to see the great savings you'll always get at Walmart ! Thanks Walmart !

Perfect for my daughter

We had to get my daughter out of her toddler bed to a Full size so that she would be more comfortable. She was used to sleeping on our bobopedic memory foam bed so we decided to get her this bed. I must say I am very impressed. With in about 30 minutes it was already to 6". I figured I would attempt to get her down for a nap in her new bed afraid she wouldn't because it didn't feel like ours and I'm shocked at how fast she fell asleep. As any memory foam bed it takes a while to break in but this is great for her and I'm excited to have my own bed back. Thank you I highly recommend.

Comfortable, Firm, Solid Quality

This foam mattress arrived exactly as described. It took less than a minute to rise to its full size. The mattress is firmer than I thought a foam mattress should be, but none the less, it is very comfortable! We also enjoy the fact it does not require a box spring. We purchased it with the South Shore Basics Full Platform Bed. The two are making a perfect sleek match for a teenage boy's bedroom.

Super Mattress

I’m surpriaed at some of thr negative reviews. First of all, its easy as pie to get it out of the box and out of packaging. I guess it coyldbe hard if you are weak. I have strong sense of smell and it has NO SMELL. So, those people complaining are just imagining it i suppose. It is a full 8 inches and is suoer comfortable! I an orderjng 2 more gor my son’s new apartment.

Fantastic mattress- best price online anywhere!!

We bought the twin and Absolutely love this mattress!!! So comfortable- true to the medium-firm description. It's soft that you “sink” in all the right place when you lay down. It is firmer, so the mattress does not envelop you. There was no chemical smell at all, and it immediately started taking its shape. It was in complete shape/height within an hour. We tested the bed after, but did not sleep or lay in it for long period of time until the 48 hour inflation period passed- per instruction. We bought this as a first bed for our baby, when he is ready and as a guest bed until then. It is perfect as both- a child will be very comfortable when transition from a crib to a twin. I cannot wait to purchase the queen. Such a great mattress for the price!!!

foam mattress

I wanted a foam mattress but was leary of the actual body support of one. I have chronic back aches and toss and turn a lot. This mattress is like sleeping on a cloud. Have actually been able to get a decent night's sleep. Well worth the time and cost to buy one of these.

Go big when it comes to foam!

I first bought a 2-inch foam from Overstock for more than what I paid for this 8" foam from Walmart. I felt the box springs through the 2 inches and woke up feeling like I'd been beaten. When I got this 8-inch home, I was worried I'd have another bad experience, but that didn't happen! This foam was a lot more solid than Overstock's. It opened up faster, has held its shape and size and depth without any problems. It has no weird oders and has an awesome shiny, wave pattern, (see pic). zip on covering to keep it clean!. And, unlike "O's" foam, it doesn't mat down. Perfect density. It fits my queen bed perfectly and I am extremely happy with it. In fact, the box it came in, I am making into a shoe holder for under my bed because it is long enough , strong enough, and just fit under great. The plastic they wrap it in is strong enough that I cut it down the sides and am saving for this winter when the windows need covered. Talk about getting something worth your money!

Comfy .... Easy

The mattress was delivered and other than getting into the glued box couldn't have been easier. I got a twin size for a daybed I purchased from Walmart too. It is a guest room so it works great. Family say it is very comfortable. Even after reading the negative reviews I got and couldn't be happier.

1. I used it on a loft bed and it's great. Be sure the thickness is ok for the bunk you choose. Theaters comes vacuum shrunk and rolled up in a 4ft box. You roll it out then take plastic off and the air expands it to full size.
by Jjj1
2. In a box rolled up
by Scottc
3. It is rolled up like other memory foam mattresses.
by Destrto
4. Yes it was free shipping.
by BigAl106
5. I definietly think you could use it in bunk beds. I had just the frame of the bed and also thought if a box spring would be in need but i laid on it myself once placed on the frame without the box spring since my son is using it i wanted to make sure he would be comfortable and it felt good. So i think you should be fine

1. I think it would feel awesome on a futon, on top of the existing mattress they come with. Our futon mattress was so very uncomfortable to sleep on. One of these in a full size would have been swell on a futon!
by Catladyx3
2. It's little too firm for me.
by one800fish
3. I would say extremely hard and firm. Just imagine a wooden board and that's it
by An anonymous customer
4. I would say it is firm but not hard firm. Extremely comfortable. Its memory foam but not at all flimsy. It has a firm bottom backing. We bought twins for bunks at our camp and my 80 year old Mother now wants one for her bed.

1. No it is rolled up!
by Heike
2. There is no soft or firm with memory foam. It is always right
by Heike
3. If you mean a box spring no, it does not come with a box spring, I purchased my son a bed frame that doesn't require a box spring from Walmart online called a platform bed it was only $60.00. But if you mean was it packaged in a box then yes!
