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.

I’m extremely impressed with this mattress. It’s a perfect combination of soft and firm, and is perfectly comfortable. I was also frankly amazed at the fact that it came packaged in a vacuum roll, and then it literally sprang to life upon breaking the vacuum seal. It’s not just a foam mattress—there are wrapped metal coil springs internally, with all the benefits that arrangement offers. Of course, it’s off gassing a little bit in the beginning, so there’s a bit of a smell that’s already dissipating after a day. Overall, I’d say it represents impressive Chinese design, manufacturing and delivery technology. It’s as good or better than brand name mattresses costing twice as much or more; there’s just no way a US manufacturer could provide this quality at a similar price. I’ll report back if there are any durability issues, but I don’t expect any. 5+ stars and an extra “snap”! Way to go, Coolio!

Purchased a full 14 inch for our son. His first big boy bed! He is a very specific kid. Can’t imagine where he gets it from. He said it’s the most comfortable bed of his life. From my perspective it’s medium firm. Supportive but not hard. I can’t sleep in a hard bed even though I have back problems. This is surprising comfortable being that it isn’t as soft as I personally like it. We have had it about 30 days. I will update if something changes but we are happy today. I want to note if you sit on the side of your bed this bed doesn’t have the strongest side support but sleep wise it’s comfortable.

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.

This is our third purchase of this mattress. As we need a new mattress, we are replacing all of the beds in our house with this one. It is perfect for my mother, who is recovering from a spinal fracture. It provides soft but firm support. It is definitely a great value. It is the best mattress we have found at this affordable price point. Sleeps like much higher-priced brands.

I love this mattress but it was a bit less firm than described by my kids. My son said it was soft and my daughter said medium. It reached full size after unpacking in just 6 hours and my son and daughter slept on it the next day after unpacking. I like that the mattress is two sided so it can be turned over for longer life. My son and daughter are in 5th and 6th grade said it slept "cool" and was not "bouncy". They liked that when one of them turned over it didn't move about to wake the other. Their old mattress was a box spring and they liked this because it makes no noise and had plenty of room for them. I am considering getting a King size for my husband and I. I was impressed by the qualty. The one downside was the mattress is very heavy.
