    • Medium to Firm
Size: Full Style: 12 INCH
So far I’m really liking my new full size mattress. That being said. I searched for plush because I didn’t want to sleep on a firm hard mattress. It is NOT plush but is absolutely between medium to firm. I’m 52 5’5” and weigh 157 lbs. If you are taller and heavier I think the mattress would feel much softer. In the end I would buy it again. I do not wake up stiff or sore and am getting very restful sleep. I have also recommended it to a gal friend for her guest room and she ordered it as well. The value for the money is excellent. Quality thus far is excellent. Sleeping temperature is also very nice. Oh it also came expertly packaged and has fluffed up nicely. I have NO ridges or valleys. ... show more

    • The bed is comfy but FIRM

The bed is fine and quite comfortable but if you do not want a firm sleeping experience… Then it is definitely not the one for you. It was very easy to unbox and it expanded nicely. Sheets fit great!

    • Good Buy/ 6mos
Size: Queen Style: 10 Inch
This mattress was packaged well when it arrived and I was able to open it with ease. It came with a little thing to open the plastic without harming the mattress which was nice! It expanded fairly quick and was at 10 inches in a day. The smell did linger for a bit but eventually it went away. As far as comfort, I’d say it’s a good 3.5/10. I am a 5’9” male weighing about 145-150 lbs and it doesn’t sink all that much. My lower back pain has improved significantly and I sleep better throughout the night. I was torn between the 10 inch and 12 inch but got the 10 due this being my first “mattress in a box” purchase. My brother in law is 6’6” and when he laid down on it, it sounded like it was struggling to support, I’d say just go for the 12 inch and spend the extra couple of dollars. All in all, it’s a good mattress and I’m satisfied. My main problem was my lower back and it’s helped tremendously. It’s comfy, not too soft but not too hard in my opinion. I would definitely buy this mattress again and have not been disappointed. Will provide an update a few months from now. Update: I’ve had the mattress for about 6 months. I’m keeping the review the same. It’s held up well. The edges are a little weak as I can’t sit on the edge without sliding off. It definitely helped in a pinch and is still pretty comfy. I’d say I sleep a little on the hotter side on this mattress. I’ll keep it but for a guest room bed because it isn’t bad at all but not my full cup of tea. Thanks for reading!! ... show more

    • Very comfortable
Size: Queen Style: 10 Inch
The mattress is thick, it really helped with my back pain. It does heat and expand very quickly. so you don’t have to worry about it. Also it does not move or make nosies of friction.

    • Comfortable full size mattress
Size: Full Style: 10 INCH
I bought two of these a little over a year ago for my teens which they are very happy with. I recently purchased a third mattress for my sibling and she loves it. Clean and pretty easy to set up.

    • Really nice mattress!
Size: Twin Style: 10 Inch
I did my research on mattresses in a box before deciding on this one, and I will admit I was still hesitant about moving forward with the purchase because I've never bought one of these before. I chose this mattress due to the hybrid construction and the 100 night guarantee, and the reviews seemed really solid. I purchased the 10 inch twin size. It arrived on time, was easy to get into the house and a breeze to open. Immediately upon opening the plastic wrap and unrolling it, the mattress starting inflating in size. Within 10 minutes, it was already at 10 inches, so I was pleasantly surprised. It is easy to move, at least in the twin size, so it can be put on a foundation and taken off easily. The top cover is very nice and overall, the construction is solid. It is a medium firm mattress, so if you're looking for a soft mattress, this isn't it. Of course, all mattresses require a breaking in time, so I expect in a few months, this mattress will be a lot softer. I actually bought a 2 inch memory form topper for it for extra cushion and that helped immensely with the comfort level until at least I have it broken in more. Overall, I am very happy with this purchase, especially for the price, easy of set up and quality. It remains to be seen how this mattress will perform over time, but so far, I really like it. There are so many mattresses in a box out there to choose from and it can be overwhelming. If you'd looking for an good, solid mattress on a bit on the firmer side for a good price, this is it. I'm pleased with this purchase. ... show more

    • No side wall structure
Size: Queen Style: 14 INCH
We bought this mattress as a possible replacement for our current mattress. We didn’t really need a new one but decided, if we didn’t like it we could put it in our guest room. Well, it’s in our guest room. The mattress is comfortable enough to sleep on, but there is zero side wall structure so don’t plan on sitting or laying near the edge of the bed. You’ll probably slip off the side. If side wall structure isn’t important to you or you’re buying this for a child, it’s probably a worthwhile purchase, but it didn’t meet our needs. ... show more

    • The BEST!
Size: Full Style: 10 INCH
I usually order a 14" thinking that would be the most comfortable. I purchased this for a guest room that my husband slept in while he was ill for a few days. He said it was more comfortable than our expensive king size bed. I tried it one day for a quick nap and did not want to get out of bed! I was just shocked how comfortable it was for the price. Begged my mom to purchase one for her guest room as we use that room when we visit. By far the best purchase you can make. ... show more
