Size: Twin XL
Style: 14 Inch Medium Firm
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 hadđ€Ł 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!đbtw no smell. Sides are not as Plush as my Beautysleep but I'm not sleeping on the side of my mattress so who cares.

I bought two of these for my momâs house, where we stay for long visits. The old twin mattresses were hurting our backs. These are a game changer. My husband and I are both on the heavier side, and they provide amazing support and comfort. No sagging, no back pain. Just a heads-up: youâll need deep pocket sheets. Totally worth it.

It's a solid bed, and it's really GREAT for back or stomach sleepers, but just OK for side sleepers. The problem is I'm a HEAVY side sleeper. I noticed I toss and turn quite a bit. However, I did come from a plush mattress (which was too soft), but I did not toss and turn while sleeping on my side. I gave this mattress 1.5 years and it works just fine though. Very durable too. With this mattress, my arm falls asleep while laying on my side while my arm underneath my body. So now I extend my arm all the way out and I don't have that same issue, but I still toss and turn and have some back aches if I spend the whole night on my side. No back issues if I spend some of the night on my back, but I can't fall asleep like that. There was a subtle smell but if you let it breath for the day or two it suggests, it goes away. Tl;DR: Overall 3.7/5 for the 12" model, but I'll round up. Great for back and stomach sleepers, not ideal for side sleepers, especially heavy side sleepers but is manageable. If this is you, GO FOR THE 14" VERSION or find a 5-6 firmness mattress. For lighter weight side sleepers, get a plush to medium mattress, not medium firm. I should have switched it during the free nights trial. It still works and I do get good sleep on most nights.

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.

I took a chance when ordering this mattress. The price was right and I just needed something for my spare bedroom for occasional use. I have a very nice Tempur-Pedic Rhapsody mattress in my main bedroom and never in my life, I thought I could find something as good as that UNTIL I received this mattress. I have back pain, neck pain, stiff muscle, etc. and this mattress is not only supportive, but also very comfortable and I noticed that I am now sleeping in my spare bedroom more than my own bedroom! BUY THIS MATTRESS
