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 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 priceAs long as these corners were fully expanded like there supposed to doOnly did 2 star because the memory foam was nice

It's been about 24 hours since I unbox ed them. (I bought 2, for bunk beds). Neither are 4 inches tall/thick. And it doesn't look like they will continue rising either.Very disappointed. Unfortunately, I can't see a way to rebox them for a return, so we'll just have to deal with it. What a hassle. And a waste of money.

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
