  • Flat to Fluffy in 2-3 hours. Give it time and this memory foam mattress will not disappoint you!
Size: Full Style: 10 inch
We laughed and laughed when this mattress arrived in an airtight vacuum sealed bag. It was as flat as a pancake. I immediately wanted to send it back but we decided to open it and see what happened. And we did. And nothing happened. ROFL. It was New Year's Eve and company was here from out of town. I wanted to cry, but they were good sports. We left it alone and rang in the New Year. When we went back into the BR a couple of hours later, the mattress was full sized and darn comfy. More laughter and toasts. This turned out to be a really good purchase. It is definitely worth the few coins it costs. I slept on it when they left. Zzzzzzzzzzz ... show more

  • Comfortable
Size: Twin Style: 4 inch
While it’s thin, for my 5 yo it’s good. Have a few blankets under the mattress just for added height, but it’s very comfortable

  • Not fully shape but function as intended
After a month of usage , the mattress did not fully shape. The four corners still wedged down. Very competitive price ( cheapest at 10inches foam mattress) . 5star rating according to price range of product even if it doesn't fully shaped (rule of life = you get what you paid for). People.....if you want full expansion and firmness, you should buy branded name mattress. Don't give low ratings for under $200 mattress in comparison with $1000+ mattress. ... show more

  • It never fully expanded
Size: Twin Style: 6 inch
Purchase 2 and 1 expanded and the other one never expanded fully. It only expanded in the center and both ends are flat and it has been laying flat for almost 2 weeks. I will never purchase again.

  • Research Before Buying
Size: Twin Style: 4 inch
We have had this mattress for four weeks and it is still not fully expanded to four inches (it is only at a little over 3 inches). In addition to this, the corners are also not expanded. Nevertheless, we decided to keep it because of its low price point, and we ran out of time to find other options. It will perform its basic function, at least for a smaller person or child. If you do decide to purchase this mattress, it is recommended that you have a box spring, bunky board, or use it directly on the floor since it has very negligible firmness. ... show more

  • I believe I need a replacement, otherwise if this is what it's supposed to be.. REFUND
Size: King Style: 12 inch
So when I first un rolled it, I noticed it was folded odd shaped (thought it was weird but didn't think to much about it at the time) then un folded it, and ripped it open because I didn't want to risk cutting it's "fancy" factory cover. I gave it 48ish hours before I checked on this thing, and let me tell you.. it looked like the troll from the first Harry Potter movie snarled up the biggest snot wad of his life and spit it on this thing.. less then 1/2 of one side was raised noticeably higher then the rest, and all four corners barely expanded at all. So I gave it another 24ish hours, the whole top was the same level and the corners expanded, but look like they could keep going about an 1 1/2" in both directions. Best believe I was weirded out by the shape of what I'm guessing is a gelish like feeling memory foam (as seen in pictures <yes i did unzip its factory cover for the pictures>) I flipped it over to see if it was the same on the other side (because it says to flip the mattress every 3-6months) just to notice it didn't have it. Decided to lay on it to see how it felt.. y'all I'm not even kidding when I say this, compared to the center arm rest in my car that's torn up like an 18yr old at her first hard-core porn audition.. this thing felt like it was chizzled out of a bolder! So I flipped it back over and laid on the amoeba shaped memory foam. Not going to lie.. it's really comfortable. But no matter what you're going to know where it stops because it goes from being all niiiiice and comfortable.. to waking up in the middle of the night having the urge to pee with the force of Niagara falls so you quickly hop up an run to the bathroom only to clip your pinky toe on the corner of your bed frame! With everything said.. if this is exactly how this mattress is supposed to be.. then y'all I'm telling you you are better off sleeping on the couch!.. But!.. if this 'memory foam' covered the whole top from corner to corner, then I would say it was definitely worth the price As long as these corners were fully expanded like there supposed to do Only did 2 star because the memory foam was nice ... show more

  • 12 inch is worth it!
Size: King Style: 12 inch
ordered the 12 inch & got just that. it took it a few hours to be sleepable (had to put the frame together first) & honestly didn’t expand to 12 inches on all sides. the corners still have no “fluffed” out to the full expansion but the mattress itself is VERY comfortable. im a heavier set person so i tend to get uncomfortable sleeping on a memory foam (because i sink in) but this mattress bounces back quickly, making moving while sleeping easier to adjust again. ... show more
