I needed some sort of bed to put in the basement of my house to sleep on regularly. I looked at a lot of options but this mattress is super comfortable. I think I've gotten some of the best sleep over the past few years on this mattress. It's not hot or anything. No smell and quickly expanded when I took it out of the package. Hopefully this lasts a long time. Very nice.

When the product arrived I was first shocked at how it was packaged I figured the box would be a lot bigger considering it’s 14” but the box was long and slim so unboxing and moving it inside was a breeze. Opening the product was fairly simple first I unraveled it and laid it flat on the bed frame slicing its vacuum seal and opening it like a bag of chips and watching the mattress shoot up in less than a second (of course give it some more time to properly fluff out. After sleeping on it for a few days now I’m very happy I got the 14” medium plush hybrid mattress not only is it extremely sturdy but it’s height is a nice upgrade from my 8” memory foam. The top two inches of the mattress is a nice and soft plush that’s very cozy for side and back sleepers alike. For me and my girlfriend we find ourselves well supported and sinking in the proper amount. If you need an upgrade wether it’s switching to hybrid or getting something a bit bigger I would recommend this for its price (I was also able to claim $50 off so that helped a lot in my decision). Now getting on and off the bed is more comfortable for someone my height (6’2) I think most people who give it a try would find it to be a nice fit and a comfortable feel.

Thought I’d have to spend over a thousand to get a comfortable mattress. Instead for just over 300 I got this medium plush hybrid and I didn’t get the hip pressure or shoulder and neck pain that plagues me with poor quality mattresses. It’s been a week and I’m pleasantly surprised and satisfied with this purchase. It is definitely 14” thick and true to size so I’ll need deep pocket sheets. Sitting on the edge for extended periods seems to cause low sinking but it bounces back. I won’t do that often so should be fine. There is a new mattress smell but kinda like a new car smell so i like it.

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.

I was unsure about going with a mattress at this price point and going from a king to two twin xls. A year later now and I made the right choice. Being a larger guy this mattress has held up, it's as good today as it was the first night. Very comfortable and nice and firm. I get in bed funny using my right knee first and that has led to all my previous matters failing in the middle, this one just takes that abuse over and over again.

Recently moved my bedroom into a smaller room so needed to downsize from a queen to a twin. I was very scared to purchase ANY cheap mattress and feel like I browsed so many sites, before landing on this one as it was within budget. Slept my first night on it last night and it was so very comfy. It’s on the firmer side but that works for me since I’m a heavier person, I slept so good! All the twin XL things I got too such as frame and sheets match too, so size is accurate. If you’re considering buying it - just go ahead and do it. Will be interested to see how this holds up over the next year!

Although I have not personally slept on it, we’ve had several guests stay in these new beds and they told us that they are very comfortable for sleeping. One guest slept for just over eight hours and told us that she hasn’t slept that long for a long time. Mattress is firm enough to keep you from sinking into it for stomach sleepers and still plush enough for side sleeping.
