If you wait a little bit it gets better
I bought this bed as an alternative to a more expensive option. I had been using a Tuft & Needle queen mattress that my sister had bought a while back and stored for some time and the bed frame I was using broke so I started to consider moving up to get a California King since I had a little extra cash to do so. I got the frame from a popular manufacturer so I decided to invest in a good king mattress and was going to go with the Tuft & Needle because it was what I had used before.The price, though, for 1250.00 (not including tax) was such a steep incline in the spending of funds available for me that I was really weighing every review, wondering if this was the best option.And then, I found Cool Gel! I found this option and somehow managed to snag it for 400.00 (plus some change) and it came with 2 pillows! I had thought I was getting a steal. Until it arrived at my home. The packaging was so lackluster. I first thought that I had gotten a used product because the packaging was so bad (fraying and loose around the edges) And then, I remembered, that each mattress comes pre-rolled, prepackaged so it would be insanely difficult to roll it back up once it has expanded.Once myself and a friend were able to put together the bed frame and then start to unroll the mattress, my heart sank. As you can see from the photo of the mattress itself, I was so concerned because for like 3 hours straight the bed was lopsided and parts of the fabric that stretched were loose, as if it didn’t fill inwards. I had never really had a box mattress so wasn’t too used to the process of letting it expand. And the pillows it came with might as well have been broken.The material inside was split in half so the pillow would sink as if it was cut in half. I was so concerned I even called the manufacturer of Cool Gel and the operator assured me it would fill out, just don’t sit on it or touch it too much at all. The time frame is 72 hours to fill out completely. And, I decided to leave the bed, go to my sister’s house and stay over for a little bit and return. I was gone for roughly 7-8 hours and immediately noticed a huge difference. The bed was practically filled out completely. Slowly rising like dough but in reality, filling out quite quickly. I put the bedding on after and decided to lay on it and it was very dreamy. At first, it is a little firm but if you give it a few days it will soften (just like some other reviews have mentioned) and this bed is worth the wait! It is cool, it conforms to your body when you rest on it, and I feel like it becomes more and more comfortable each night.The pillows are also working really well! They finally filled out and fit their cases snugly. In combination with the soft bedding I got in conjunction with this new bed and bed frame I feel like I got lucky. I would say don’t pass up this bed. Wait for it to go down in price a little and then snag it. I honestly think it was a great investment, especially for the price I got it at!

It is SO hard to get out of this mattress, you will never want anything else. New technology.
My son convinced me to get one of these after I had been sitting on his. He said, ‘that’s old tech you have in your room… THIS is the new tech.’No boxspring, and so comfortable, you won’t want to get out of it. Helps you keep from hotboxing your body heat, as the material is pretty efficient at channeling away excessive body heat… Comes with two pillows that do the same although not as effectively as the mattress does.Make sure to get the hardness you want, since they have varying hardnesses. One of my sons has medium, I think mine is medium firm, like my oldest son’s.The price is a great value, especially when you consider there is no need for a boxspring. Overall a Wow! factor in your search for an improved quality of life. IF you haven’t had one before be sure to look at the height of it and get a frame that will have the height to net out to where you like the top of your bed to be if you used to have a boxspring.A final thing to know, this thing is heavy and vacuum packed. Don’t break the vacuum until you get it where you want, and if you are a smaller lighter person it is useful to have a helper (although you’ll get it eventually!) If you break the vacuum it is going to expand pretty rapidly (and in fact you will want to give it a few minutes when you DO want to finally place it to fully flatten out and expand). Enjoy!

Best Mattress I’ve Ever Owned
My wife and I purchased this mattress (California King Size) back in June 2020 when we first got married. Before I’ve only owned and slept on traditional innerspring mattresses. This mattress replaced my 7 year old Queen Sized mattress I had in my apartment. We are both are fairly tall people (I’m 6’3 and my wife is 5’9) so we needed something a little bigger. My wife had a Full Sized mattress that was a non cooling model from her apartment that we put in our guest room. One night I slept on that mattress and loved the feel of it but was SUPER GROOSED OUT by how soak and wet I was with sweat when I woke up in the middle of the night. I’m a very hot sleeper so I knew from then on that if we were to get a foam mattress it would HAVE to be a cooling foam model.This is my first Foam mattress and let me tell you, a year and 6 months later…I ABSOLUTELY LOVE this mattress. It sleeps cool all night long and has a perfect firm and plush balance. This is honestly one of the best purchases we have ever made. Super happy.BTW we sold her mattress and replaced it with a Queen Sized Cooling Foam Mattress for the question room. Lol.

Stay Away From This Mattress!!!
The short and sweet is this. When I first got it, it was great. I’ve had it for about four years now. Over time the mattress hardens up and my lower back pain got worse. The bigger issue is that it leaks fiberglass from underneath. I never removed the cover, but after shining a flashlight at my floor and at the bottom of the mattress you can see all the shards. The company is out of business, but after contacting Amazon and sending them photos they gave me a full refund.
