    • Most comfortable bed I’ve ever owned
Size: Queen Style: 14-inch
I was very skeptical about the whole idea of a bed in a box because I’ve always purchased mattresses in person. That said, I thought I’d try it because it’s let’s than half what I’d normally give for a decent mattress. I love it! There is no movement when my 6’4 husband moves around. There’s no noise or squeaking at all. It fit my frame perfectly and all Queen sheets I’ve tried have fit well. It’s very easy to set up, just unfold and cut the plastic. We didn’t sleep on it for a full 24 hours and the first night I did sleep on it, it was uncomfortable. I assume that’s just because my bad back wasn’t used to this type of mattress. It molds around your body but otherwise there isn’t any give to it. The second night, and every night since then, I’ve slept well and wake up feeling refreshed without the usual back or hip pain. That is a BIG deal for me!! I have scoliosis but I also broke my lower back in a car accident and have had so much pain and discomfort since. This is the first mattress I’ve been able to sleep comfortably on since 2007! I highly recommend this mattress and will definitely buy again. It’s been almost a year and it still feels great! ... show more

    • A Man's review of this thing.
Size: Queen Style: 12-inch
To clear up a lot of confusion with this mattress, here is an Honest to God review.... Summary: - Mattress was easy to assemble (cut package and roll/air out) - Smell was not that bad... It's expected, so have a fan ready and air it out. - Firm version of memory foam (Perfect for bigger guys like me) But I have a hunch it breaks in over time. - Quality seemed very nice. I just received this mattress yesterday ( 8/5/2015 ). The packaging was as expected, the Cardboard box was in rough shape but the heavy duty plastic on the inside was untouched. I'm a 6'2" 230lb athletic man that spends most of my free time in the gym, so getting the package onto my bed frame by myself was no problem at all. To a regular or smaller person, you might need an extra hand carrying the 90+lb package. Upon opening, I cut the plastic and everything went as expected. The mattress inflated itself within 30 minutes with the corners lagging behind (I just hit the corners with my hand to fluff them up and help them catch up) . I let it sit for 24 hours before laying on it. The smell is strong, but it's not as bad as people make it out to be. Looking at the other reviews, some of these people must have had a bad mattress, or simply can't take a little odor for a few days (they might be sensitive). Here's the biggest point... The mattress is a very firm version of memory foam. Right out of the box the mattress doesn't give in as much as you may think. It's perfect for someone like me because, like I've said, I'm 230 lbs and athletic. This thing offers the perfect support for me, giving in to my heavy points and supporting my lighter areas yet I can see somebody who's much lighter having issues. I say to those people, give the mattress time to break in. I'll update this in a few months with a follow up. Tonight will be the first night I sleep on it, and I couldn't be more excited. The 10 minutes I spend laying on it this morning almost made me fall right asleep again. I'll keep this post updated because there seems to be a lot of confusion on this mattress. * Off topic * The first one I ordered got mixed up in the mail due to the carrier, therefor I got my mattress 3 days late. Amazon's customer service was perfect and I couldn't have asked for a better crew to solve the problem. ** UPDATE (08/07/2015) ** - Last night was the first night that I slept on the mattress and I can honestly say I had a great night sleep. I didn't wake up in the middle of the night at all. I was cool all night (Granted I had a 17" box fan blowing directly over me) and the only time I got hot was when my lady friend came over earlier. I'm usually a very hot sleeper and people who complain about the heat of this thing should invest in a fan. Even without the fan it was very cool at first, but it did start warming up slightly after 30 minutes or so of laying in the same spot - but it wasn't that bad. I can say that I'm very pleased with my first night on this thing. *** UPDATE 08/24/2015 Sleeping on this thing has been a pleasure. It's not revolutionizing, but it's much more comfortable than my last mattress. The smell is pretty much gone although it did take awhile. The smell was honestly not that bad and the only way you could really smell it was if you stuck your nose in the mattress. I don't wake up in the middle of the night anymore from tossing and turning. That's a huge plus for me because on my old mattress It felt like I had a cycle of waking up at 3 or 4am from tossing and turning. The mattress is still very firm, but like I said before, it's perfect for me because I'm big and heavy enough to actually sink in a bit. ... show more

    • Worth the purchase!!
Size: King Style: 12-inch
I went mattress shopping and they were all so expensive. Everyone said get off Amazon. I was so reluctant bc I have a bad back and extremely picky. I watched all the reviews and videos on this mattress b4 buying. Even though there was one negative one that stuck out I decided for the price it was worth the risk. Needless to say I am extremely happy with my purchase. I will never buy an overpriced mattress from the store again!!! ... show more

    • Well made just to soft for me
Size: Queen Style: 14-inch
First of all, I'm a male 66 yrs old with a bad back. I had such high hopes that this would give me some relief. It's very well made and my pups really love it. But I still wake up in pain. If I could send it back I would. Why the 4star review? For the average person it would be great!
