Good Buy!

Feels great on my pressure points. Good buy if you can’t afford the more expensive mattress. Reached five of the eight inches within minutes. Allow it time to reach full height. You’ll be satisfied.


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!


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 !



Okay so I was researching mattresses for awhile . Wanted and affordable yet comfy mattress my back hurts soooo bad from spring and coil mattresses so I finally choose this one . Shipping was great and quick and the packing was easy . I opened the box up took the mattress out and it unraveled pretty quickly as soon as I took it out it began to rise after an hour it was at 5 inches or so and after three it was 8 inches of heaven . I can't express to you how happy I am with this mattress it's firm yet comfy . This mattress overall is 5 stars . I'm a small girl 5"2 but my boyfriend is almost 6 feet and we sleep like angels ! High recommend


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.
