Comfy for a 5'5" 120 lb person, more medium soft
This mattress is so so comfy and cushy! At the time of this review my mattress is still not fully expanded, it's only been 24 of the 72 hours recommended for full expansion. However I'm laying on it now because it beats sleeping on an air mattress, and I read somewhere that you can sleep on a hybrid mattress after 24 hours of expansion, and it will continue to full expansion without harming the mattress, so perhaps do your own research but I'm going with it. But yeah, I am a 5'5" 120lb female and a single sleeper, and this suits my frame well! The mattress is more in medium soft side to me, but it's firm enough support where Im not sinking in, and the pillow top is really nice and coushy and cradles just slightly - so it's cozy not sinking ,But I'd definitely let it expand for at least 24 hrs, I opened it at 8pm last night, and for sure I saw a big difference in the the look of it once I got home from work tonight, it's about 9pm the next day. No smells to me, just a nice fresh expanded mattress! Its also has handles, and is pretty easy to move around by myself. It's great!

Great value for the money
I was skeptical about buying a mattress. To my surprise it is really nice and comfortable! It took a day to fully fluff up from the packaging. This is a great buy. Well worth the price!

Didn't wake up with a sore back
Needed a full size mattress and a pinch so I went with this hoping and praying that it wouldn't disappoint me and it is extremely comfortable. I really enjoy this mattress. It gives me the comfortability that I need. It's not too hard. It's not too soft. It's just in between

This is an awesome mattress, it is soft and was easy to set up. It fit perfectly into my teenagers double sized bed and is the perfect thickness. It makes no noise and the height sits right at the bed rails like it should. Happy Kid Happy Parents

Fantastic bang-for-your-buck bargain mattress.
I was on a very tight budget and this seemed like the best bang-for-the-buck option. I shopped other hybrid mattresses on MattressFirm and other locations and the best I could find was an 8" hybrid full size mattress for about $60 more than what Amazon was selling this one for, so I pulled the trigger. To be completely honest I wasn't expecting much. I was expecting something floppy, weak, squishy, and not terribly supportive. I'd heard lots of stories about weird chemical smells and uncomfortably warm sleeping situations with memory foam mattresses, but given my budget I didn't have much choice. The mattress arrived the day after I ordered it in a heavy box. When I realized it was all rolled up and vacuum sealed I prepared myself for the worst. It was, I admit, oddly satisfying laying the mattress on the bed frame and watching it "inflate" after I broke the vacuum seal. I let it breathe for about an hour. There was a slight chemical smell but nothing crazy, no different from (for example) the smell of a new shirt before you put it in the laundry and certainly not something that was going to be a problem. Once it was "inflated" I sat on the edge -- and sunk down. It compressed a LOT, almost to the frame rail, and I got concerned. After some experimentation I found that the mattress is very sensitive to distribution of weight. If you lie down on the mattress you don't sink appreciably more than you would in any comparable mattress, but the more weight you put on a smaller area the more you will sink down. So sitting on the very edge or corner of the bed is not a good thing, but laying down on the bed or sitting further "inland" on the bed (so your butt and legs distribute the load) makes things easier. After some internet research I found that this is pretty common for memory foam and hybrid mattresses so I'm not faulting this specific mattress for that issue. The mattress is light and can be easily moved in comparison to a traditional spring mattress. The "pillow top" is comfortable and looks "okay" in terms of construction quality. There are some places where I'd have liked to see more stitching or better reinforcement, but time will tell. That being said, while I don't have anything really negative to say about it in the short time I've owned it (about a week as of this writing) I'm keeping this review to four stars rather than five. I will revisit this in a few months and see if my feelings on it have changed at all. As it stands now, this is a fantastic bargain-priced mattress. It comes with a ten year warranty so they've got some confidence behind it, but TBH even if the mattress lived only half that long I would still consider it a bargain.

Guest Approved!
I bought this mattress for my guest bedroom for those staying with me after my surgery. My first guest has already told me it’s extremely comfortable. When I sat on it after opening and leaving it for a few days to regain its shape I noticed the edges are a little soft so I wouldn’t recommend it as a stand alone mattress but it’s great on a bed frame and I bought comfortable cotton sheets so the whole set is working for my first guest even better than expected.

Great mattress
After a poor mattress (another company), I tried this one. Went up to 12 inches. Comfortable yet supportive. I’m buying another.

Greatly quality
Make sure you check it, if it unzips you have been scammed. It should be a solid covered mattress. It's soft, if you like soft beds this is for you. I prefer something a little more solid.
