CoolvieKing Mattress, 12 Inch Mattress in a Box King Size, Hybrid Construction Individual Pocket Springs with CertiPUR-US Certified Foam, Cooler Sleep with Pressure Relief and Support

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.

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? yesWould 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 skeptical. I have never purchased a bed in a box before and within a matter of months, I had to purchase a new bed for the house and the camper. It was way to expensive to get traditional beds for both places. We chose this one for our everyday bed, and I'm glad we did. Right out of the box it started to expand. Be aware though, and follow instructions so that you don't get hurt!!! It comes out fast once you use the provided tool to open it up. It says to give it like 3 days to fully expand, we only gave it 2, and it was perfect. The only thing, I wish I would have went with the thicker one. We were replacing an old mattress and it was a tad thicker with a pillowtop, so when we put this on top of our box springs, it sat a little lower and that took some adjusting. But it fit perfectly on the box springs, our queen mattress cover and sheets fit it very well, and the overall of it was great. It didn't smell either. I think I read somewhere that out of the box it had a strange smell, ours did not. Actually, no smell at all.Now, let's talk comfort. It is very soft. It does sleep well, but I have issues with my hip (and of course I'm a side sleeper) and sometimes if I sleep too long on one side, my hip will ache. Not a big issue, because my hip hurt with the old mattress too, but that old mattress was 20 years old! LOL. I feel like this one should be more cooling, as well. My husband is always hot and this doesn't help in that area, so if you are looking to have some cooling.... wouldn't be my first choice.Overall, for the price, you can't beat the bed.Happy Bed Hunting!

I love this mattress. Ordered yesterday evening and arrived next day in the morning. Delivery man was great carried it into my garage with a smile. Long narrow box. It was heavy but I were alone I think I could have managed dragging it into the house alone due to the way the mattress was packaged. I was impressed the way it was rolled up and sooo easy to unravel. I even received a cutting tool for the plastic and as soon as it was punctured the mattress began to inflate. There was no odor whatsoever and it looks great and seems to be good quality for the price. The pillow top is soft yet firm enough to give support. I have no regrets purchasing this. For under $500 I couldn't ask for better tbh If your thinking about purchasing this mattress I think you will be pleasantly surprised.

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.
