    • Amazingly Comfy!
Size: Queen Style: 12 Inch
This is my first bed in a box I've ever bought! I was a little nervous about the low price and not knowing what to expect, so naturally this has sat in my cart for quite a while. I purchased this mattress to replace my extremely old pillow top that I've had for well over 10 years. We have only slept on this for two nights so far, but OMG I am so impressed with how comfy this bed is!!! -We let it sit for one full day before sleeping on it, but it was pretty much ready to be used as soon as it was unpacked. No weird or chemical smells after opening. It also arrived three days early during the height of Christmas season! -Be careful when you cut the plastic off this mattress. It's vacuum sealed and literally burst open with enough force that it actually pushed me back a bit due to the inner coils! To be fair I probably opened it improperly. -It's definitely a true medium-firm. I HATE super firm mattresses. It is firm enough to provide support and soft enough to be comfy and cozy without sinking. I don't feel like I'm sinking into this mattress at all, and there are no imprints left from me sleeping on it all night. If it were any firmer it would be like laying on a board. -The edges of this bed do sink in more easily than the rest of the bed, which is to be expected considering ALL mattresses lack edge support to differing extents, but not nearly as severely as some of the other reviews had led me to believe. Some have suggested that you can't even sit on the edge of the bed without sliding off, which is honestly just silly. You absolutely can comfortably sit at the edge of the bed without sinking in or sliding off, unless you weigh over 250 pounds or are using this bed with no base. We have this bed on top of our old box spring. My partner and I are both 30, weigh around 180 and have had 0 issues with the edge support so far. I actually sleep very close to the edge of my side, and I don't feel like I'm sinking or sliding at all. -I am an all-sides sleeper, I'm turning in bed all night like a rotisserie chicken. I find any sleeping position equally comfortable on this bed. It doesn't absorb movement to the same extent as a full memory foam mattress, so if you're sharing this bed with another person/doggy/etc you will feel them move, as you would with any other mattress other than full foam. -This mattress does hold onto heat. I run hot at night and I can definitely feel the difference between my old mattress and this one. It's not excessively hot but it's enough to be noticeable. I will update this review should something go horribly wrong but overall I'm really, really happy with this purchase! It has been worth every penny so far, it's an excellent mattress for the low price point and I would absolutely purchase again. I'm so happy to have a comfy bed again. I can't wait to sleep in on this bed on Saturday morning :) ... show more

    • Firm and sturdy
Size: King Style: 14 Inch
While the bed is firm it's also forgiving and has comfort to it too. I'm surprised at the quality for the price and the only reason I gave it a try was because a friend suggested trying theirs. It's easy to set up (but be careful it can have a kick to it when you finally release it) and light enough to rotate or move a bit when putting sheets on. ... show more

Purchased 2 of these mattresses for our guest rooms. Very easy setup. There was no smell and the mattresses started expanding immediately and appeared fully filled in after only a few hours. To avoid any issues we did give them a full day to inflate. Our guests have told us that the mattresses are very comfortable and they slept great on them. This was a big relief because buying a mattress for different body types was nerve-racking. I tested the water resistance of them and they do bead off water fairly well for normal spills. Overall, very happy with these. Functional, good quality = well rested guests! ... show more

    • Comfortable! Really good for the price

Review Image by Garrett Rucker Garrett Rucker
I was a bit skeptical buying a mattress online but figured I would for the price. We needed a new mattress since ours was about 10 years old and literally caving in. We did not want to invest in a really expensive mattress since we are planning to move into a house in a couple of years and get a king. The mattress came really fast and was delivered by UPS. It was easy to set up and super fast, it was heavy but I managed to do it by myself as a 165 pound woman that works out. It puffed up as soon as I cut it out of the plastic, it didn’t shoot out or anything it slowly had air and by 2 minutes it was inflated. The mattress is really comfortable, the only reason I didn’t give it a 5 star was the edges don’t have as much of support as the rest of the mattress but for the value for money it was definitely worth it. This was my first mattress from a box and I have no complaints upon opening it. We got the 14inch, it’s super tall especially with a box spring. There was no smell when opening the box. I recommend this if you’re looking forward for something cheap and comfortable! ... show more
