I bought the Coolvie 12-inch twin-size Hybrid Mattress a few months ago for my 13-year-old daughter, and so far, it has exceeded our expectations. It arrived quickly, although the box was a little heavy for me to carry upstairs by myself. The instructions for opening the box and unwrapping the plastic were clear, and it was satisfying to watch the mattress regain its shape in just a few minutes. The hybrid design, which combines the support of innerspring coils with three layers of premium foam, really sets this mattress apart. My daughter finds it very comfortable, with the foam providing just the right amount of softness while the innerspring coils give it a supportive feel. After several months, she still reports sleeping well and hasn't experienced any sagging or loss of comfort. For the price, this is a fantastic product. It offers the perfect balance between comfort and support, without breaking the bank. If you’re looking for a quality mattress that’s easy to set up, comfortable, and affordable, I would definitely recommend the Coolvie 12 Inch Twin Size Hybrid Mattress. It has made a noticeable difference in my daughter’s sleep quality, and we couldn’t be happier with the purchase.

This mattress fit our bed frame perfectly and no box spring or extra support was needed. It is quite firm as we were hoping yet is still very comfortable. There is no noise when turning over and the thickness worked great for our setup. It only took a few hours to rise up and set up into the frame and did not have any smell that some tend to have. I have been sleeping on this mattress for a month now and can say that it meets all expectations and I'm getting a good night's sleep. For the price it was a very good choice to replace the old mattress that was tossed when we moved.

This a review on the Coolvie 14in. Medium Firm XL Twin Mattress. I truly did the research on this mattress by reading all the reviews. Therefore I wanted to write a review that would hopefully be helpful and informative. I had 2 TwinXL Beautyrest 14in. Medium Plush Recharge Contenders that were over a $1000 each almost 10 years ago when we bought them. My husband and I have 2 twin xl mattresses because we have adjustable bed bases that make a King. My bed had deteriorated at a faster rate than my husband's because I have disabilities in my back and heart so I'm always home. When we went shopping for mattresses during Labor Day the prices floored us. Therefore I researched and took a chance on this mattress. We only bought one for me now and got the 14in Medium Firm. If all stays like it is we'll get the Medium Plush for my Husband. We ordered it during Prime Days and got a great price $264 but the regular price for this mattress is also very incredible fairly priced with the $50.00 normal coupon for the mattress of $329.99 is $280 which already is a Great Price so it'll end up less than $600 for a King. The Mattress arrived on a Sunday three (3) Days early. I was so happy when I got the text that it was coming early. My husband and I were careful. He took it out of the box and cut the saran wrap and it's easy to unwrap. Did not unroll. My husband then tore open the the vacuum sack with tool they provide then the decompressing starts. Wow that was so cool. We left it like that for 24 hours and after one day it was already at almost 14in. I periodically checked on it for the growth but it pretty much didn't grow much more after 48 hours. After around the 60 hours we took it to our bed and that night I slept on it. I think that has been the best night's and next day's sleep I've ever had🤣 I woke up the next morning and accidentally fell asleep again and woke up 3 hours later. I will update in a few months if needed, but right now I will give this bed 5 stars out of 5 stars. It is firm but soft. Works perfectly on an adjustable base which I was worried because read a review that said it didn't but knew it did because innerspring mattresses should work with adjustable bases and as you can see in the picture it does!😁btw no smell. Sides are not as Plush as my Beautysleep but I'm not sleeping on the side of my mattress so who cares.

In Spring 2024 I bought a well-reviewed, but lower cost, full sized mattress in a box from Amazon for my spare bedroom and was shocked in a good way when I was given a specific delivery time option and discovered that mattress was delivered and set up free of charge by Amazon (and there was an option to take away an old mattress and box spring at NO EXTRA CHARGE). I mistakenly thought that's how all mattresses were sold off Amazon only to later discover by trial and error that this option now exists for only selected, upper range quality mattresses that are specifically sold and shipped by Amazon. I am a big guy and weigh over 240 pounds, but find this model of Coolvie mattress to be very comfortable for me to sleep on as both a side and back sleeper and very supportive of my body weight. The other amazing thing is I can sit on the edge of this mattress without it collapsing. If you read the reviews of most other "mattresses in a box" (even the more expensive ones), you will hear customer reviews saying you will slide off the edges. I also took advantage of getting an Amazon Prime credit card with no annual fee that further reduced the cost of this mattress (in addition to the Black Friday price) by an extra $200. I am a happy camper after the first two weeks. Will update if my experience changes.
