  • Great value for the price
Style: 12 Inch Medium Firm Size: Twin
Just as comfortable as beds that cost twice as much. Very well made, very comfortable. As with any new bed or pillow, it takes about a week to get used to it. It's been two weeks, and I'm sleeping great. Very happy with this purchase. Highly recommended.

  • Not what I excepted
My old bed was so bad I was sleeping on the couch. I had gone to numerous mattress stores trying to find something reasonable. As with the present economy spending a lot on anything is not on my wish list. While at one store I laid on a bed and said this isn't bad but just a little soft for me. He explained it was a bed in the box. When I looked the reviews up on that one they were similar to what I felt when I was on it. So I continued to search. After reading the reviews I thought well its 1/4 of the price of the other ones I have seen and liked. Its incredible to me they can put this in a box. There is no way ever it will go back in one without a device to suck the air out and some work. According to the manufacture you have to let it decompress for the full effect of about 3-7 days. However, you can sleep on it before hand and doing so will not effect the decompressing. So night one I laid on it and it felt extremely springy and I was like "oh no this isn't going to be good". Plus it was very soft. It sank when you got on it. Second night wasn't to bad but not great. It didn't sink as low as the first night. However, I slept through the night. I also found it to be a bit hard more firm than med /firm, by the third night. I had a mattress topper from my old bed that is still in like new condition. I threw it on top and the next night it wasn't much better. Now I'm on the fourth night with it and I have to say its comfortable. I'm keeping my topper on it and if I take it off its to firm for me. Its firm more than medium. Plus it doesn't sink at all now. Nor do I feel the springs, nearly as much as the first night but I can still feel them. Side note: The center is softer to sleep on than the sides. So that is a little odd to me. Its not consistent around the mattress and this is night 6. I have a king size bed and have normally always slept one side or the other but right now its strictly the middle. Firm in todays standards is more like sleeping on a board. 20 years ago firm is more like a medium in todays time. Will the mattress last ten years? I don't know about that but for the moment it will work for me. Now it is two weeks in to sleeping on this and I don't wake up in the night nor do I toss and turn all night but I wake each morning with the middle of my back slightly sore. I'm not sure if this will be good for the long term but for the moment its working. Would I buy it again? yes Would I recommend it? probably so. Size and weight do matter in mattress shopping. Would I buy it for my son? No because he has a 6k bed and would know the difference. EDIT: It's now been several months since I bought this. It's completely decompressed, and I love it. Legit its so comfortable I actually want to go to bed. I have left my topper on it and its perfect for me. If you like a firmer mattress, you don't need the topper, but my topper makes it kind of like a pillow top. I sleep like a baby. I also live in FL on the beach and even in the worse of the storms we have gotten this season I slept through every one of them. My neighbors look at me like I'm on crack when I told them I didn't wake. i think they are now concerned for me. Just saying. I'd definitely buy this again. ... show more

  • Cautiously Optimistic
Style: 12 Inch Medium Firm Size: King
So far so good! I know most of you reading this will be just like I was when I was shopping for a new mattress, to sum it up into one word, nervous. This is a big purchase, and one that is difficult to undo should things not work out. I have issues with low back pain on firmer mattresses, but I also don't do too well on ultra plush mattresses either, so it is a fine line of what will work for me. I also deal with shoulder pain on both sides when side sleeping. I'm a physically fit guy, 6'0, 155 pounds, but I've been in a lot of tumbles in my three and half decades, and consequently I have some pain that typically only develops after several hours sleep on a mattress that is not ideal. I am relieve to report that so far, this mattress has performed beautifully. It came quickly and safely, was very easy to unpack, and very quickly took full form. As soon as I laid on it for the first time I knew this was going to be a game changer, instant comfort, softness and a plush that is just right, not too plush, but more importantly, definitely not too firm! I've had the mattress for about two months now and I have absolutely gotten better rest every single night in the past two months then I was getting on my old mattress. At this point I have to say this mattress is not only excellent quality, but an equally excellent price for what you're getting. I would have imagined having to spend twice or even three times this much for a mattress with this level of comfort, unless it unexpectedly begins to decay or lose its form, comfort or otherwise, though I do not expect that to happen. If I remember I will will post another review in six months to see where its at and hopefully help others to make an informed purchase, but at this point, I'm very pleased with my decision to purchase this mattress. ... show more

  • Perfect - firm but comfortable mattress
Style: 12 Inch Medium Firm Size: King
Waited about 2 months since getting this to leave a review to see how this bed holds up. I am extremely happy with this mattress. I spent hours trying to choose a mattress and was terrified to pick something uncomfortable that would be unrealistic to return. I can safely say 2 months in that this mattress was the absolute best choice. It is firm. If you don't want a firm mattress, do not get this. I need a firm mattress due to back issues and this fits the bill. However, while being firm, it is still very comfortable with a little give on the top. The mattress was very easy to unpack and expand, we let it sit for 24 hours before laying on it but it was pretty much expanded after an hour. Can't feel the springs at all. I've genuinely been getting the best sleep of my life on this, and my back hasn't been bothering me at all. My only complaint is that the corners are a little scrunched. Overall I highly recommend this couch for anyone looking for a comfy firm couch. ... show more
