Awesome, we love it!!! We needed a new mattress and had a super tight budget. And thus began the mattress in a box search.....after reading loads if reviews we decided to give this one a go and we are NOT disappointed. Obviously everyone is different but my hubby and I are both comfortable and sleeping better on this mattress than we have been or slept in a loooonnng time. It's not too soft so you don't sink way in but it's not rock hard either. We let the mattress hang out in the box for a couple days since it was cold outside when it was delivered. Once we opened the box the mattress plumped right up to it's full height with no weird un-plumped spots and no weird smells. Been using the mattress just over 3 months at the time of this review. We would highly recommend this if you're on a tight budget and still desire a super comfy mattress!

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.

I love my bed. Owned for 6 years and it’s super comfortable for my wife and I. Supportive, you can’t tell if your partner moves out of bed. I’ll never go back to a standard coil bed again and I’ve had the experience of sleeping on a $5000 mattress at a family member’s house, it was very nice but that’s a lot of cash for a mattress. This is a quality bed at a bargain price. I will buy the same brand again when this one starts to fade away. Great job building this mattress.

This is the second memory foam mattress I've purchased. I loved my first memory foam mattress (different brand), but I was forced to leave it behind when I moved 1800 miles away. I was using a hybrid memory foam mattress after the move, but I suddenly began waking up with back pain & knew I wanted to get another full memory foam mattress. I couldn't find the same memory foam mattress I previously purchased, so I took a chance on this one. I allowed this mattress to expand for about 48 hours to reach it's full size. Thankfully there was no harsh chemical smell after opening. The first thing I noticed is this memory foam mattress is much firmer than my first one, and I was a little worried I wouldn't like it. However, after sleeping on this mattress for a few weeks now, I am happy to say that I stopped waking up with back pain. I don't find this mattress quite as comfortable as my previous mattress due to how firm this one is, but it doesn't seem to interfere with my ability to sleep. I also noticed that I do sleep slightly warmer on this mattress, so I wouldn't recommend it to people who tend to be hot sleepers. The biggest plus is that I no longer wake up with back pain, so this mattress must be very supportive. It would be a huge pain to return a mattress like this, so I am going to keep it. Because of how firm it is, I will probably try a different brand memory foam mattress the next time I need one, unless I find a mattress topper that helps to make this one slightly softer.

Just buy this bed. It’s the one. And I do not say that lightly. My husband has had three back surgeries and I have hip dysplasia. When I tell you we’ve tried every brand of mattress out there, I wouldn’t be lying. We’ve had tempurpedic, stearns and foster, saatva, helix, Serta icomfort, and many more I can’t even remember at this point. We’ve never found one that didn’t make us hurt every morning. Until now. I know it sounds ridiculous that a mattress in this price range would be better than a mattress that costs thousands of dollars, but I am here to tell you we are sleeping so well and we have no pain in the mornings. We’ve had this only four nights so far, but ya know what, even if by next year its support has weakened, at this price we will just order a new one! Extremely pleased with this mattress. And the pillows that come with it are incredible also!
