Features

  • Cooling FabricThis queen mattress was thoughtfully designed to allow maximum airflow, beginning with 3D soft knit fabric on the top cover which is breathable and skin-friendly, absorbing moisture. Underneath, innerspring coils work in tandem to help disperse heat. By regulating body temperature, reducing sweat and discomfort, it promotes deeper sleep stages, and enhances the overall sleep quality of your sleep for a more restful night.
  • Support and Pressure Relief5-zone innerspring, with up to hundreds of pocketed coils that provide exceptional lumbar support and will closely conform to your body regardless of sleeping position for a comfortable night's sleep. The individually pocketed coils not only deliver excellent support but also ensure superior motion isolation, minimizing disruptions from your partner's movements throughout the night.
  • Strong Coils for Firm FeelEach spring is separately wrapped, so they can move independently to provide customized contouring. Coolvie features thicker coils on the entire perimeter for enhanced edge support. Individually wrapped springs help minimize motion transfer.
  • Eco-friendly ChoiceThe king size mattress premium foam is made with CertiPUR-US certified foam and safe fabric, making it a satisfying option for those with allergies or skin sensitivities. Better still, no chemical or fiberglass fire socks. Just pure, healthy luxury.
  • Rest Easy with our 100 Nights Protection Your satisfaction and peace of mind are our priority. If there are any issues with your mattress, our dedicated customer service team will be there to assist you.

  • Comfortable bed
I like how firm it is, it’s great for my back. It’s was so easy to set up!

  • Seems to be really well made
We are very pleased so far with the beds. We went ahead and purchased 2 twin xl instead of 1 king mattress. Of course when you do something different you worry about how it will all work out. First of all, within 5 minutes, the beds had reached their 12 inch height. Boy that was a relief. Many do not get to their advertised height. We let them wait for about 82 hours before we actually slept on them. I honestly think that's a very good thing to do. If at all possible let the bed completely fill out inside and out. The only thing I would like to mention in case it matters, is that our 2 beds ended up being about 40 inches wide instead of 39 inches. Now we thought we were going to have a real problem because these two mattresses were going on one king frame. Plus we put side retainers on the frame to keep them from sliding or moving. At first it didn't look like it was going to work for us. My husband lifted them up in the middle and them slammed them down. Voila' we now have our mattresses where they need to be. I didn't have to buy twin sheets either. My deep pocket kings fit great over the 2 mattresses. I actually have to hunt for the seem where the 2 beds come together or I wouldn't know it wasn't one mattress. We've been sleeping on it for about 3 weeks and so far, so good. I think it's just right, not overly firm but not mushy either. I would like to mention that the sides are not real supportive so you might want to be sure you sit a little further back when you get out of the be. ... show more

  • It is a good bed, but...
Size: Queen Style: 12 Inch Medium Firm
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. ... show more

  • Neutral
Size: Full Style: 12 Inch Medium Firm
The vendor contacted me and went above and beyond to help me find a solution that works. The customer service is above and beyond. My back hurts every time I sleep on this thing. Looking for a new one. Problem could be that is not my personal sleep environment. Might work for someone else.

  • Just What I Was Hoping For
Size: Queen Style: 12 Inch Medium Firm
Coolvie 12" Queen Size Hybrid is what I hoped it would be. Comfortable from the start! I usually prefer a firm mattress, but after reading the reviews I ordered medium firm. It's what I expect in a mattress; enough firmness to support my 6'-5", 220 lbs. frame, and comfortable enough to fall asleep quickly. Unboxing was easy enough and any odor dissipated within 24 hours. ... show more

  • Needed this and
Size: King Style: 12 Inch Medium Firm
I needed this mattress and did know it!!. One of thr best purchase I could have made. I placed the mattress on my old box springs. I sit up high but we'll worth the money. My hubby and I are large individuals and I don't feel him moving. Does not smell and is firm but not too hard.

  • Comfortable
We purchased two twin to form a king size. Works very well and the mattresses are comfortable. Be sure to use a twin to king conversion kit. This will keep the two mattresses from separating plus eliminates the middle seam.

  • Expanded Quickly!
Size: King Style: 14 Inch Medium Firm
I'm really hoping to be able to keep this bed. I'm letting the bed sit for 3 days as the directions suggest. Today is day 2. It appears to be fully expanded, but still has a smell from the plastic. I'm super sensitive to things like this so hopefully the scent goes away by day 3/4. I picked Firm, it does feel firm in the center so far, around the edges not so much. I felt the price was fair. I'll be super excited to see if this gives me great back support. Will follow up once I've slept on it. ... show more
