- COOL SLEEP COPPER GEL FOAM WITH COOL PHASE STRETCH COVER: The Cool Phase cover feels cool to the touch and stretches with you, so you settle into the foam instead of resting on top of it. Copper-infused gel memory foam is built for hot sleepers who run warm at night.
- US-BASED COMPANY, ASSEMBLED IN THE USA: ROOST SLEEP is a US-based company and this mattress is assembled at our US facility with CertiPUR-US certified foams.
- ZONED LUMBAR SUPPORT - FIRMER COILS THROUGH THE MIDDLE THIRD: Individually wrapped pocket coils are built firmer under the lumbar zone, where most of your weight sits, and softer at the head and feet. Targeted support for side, back, and stomach sleepers.
- REINFORCED EDGE SUPPORT, ADJUSTABLE BASE FRIENDLY: A perimeter support system keeps the sides firm so you can sleep and sit all the way to the edge. Flexes with adjustable bed frames, and fits standard platforms and box foundations.
- CALIFORNIA KING - 72" x 84", LONGER AND NARROWER THAN STANDARD KING: Check your frame before ordering; Cal King is 4" narrower and 4" longer than a standard King. Pocket coils spring back within hours of unrolling, so it is ready to sleep on the day it arrives.
- This is a CALIFORNIA KING mattress (72" W x 84" L) which is longer and narrower than a standard King. It is specifically designed for California King bed frames and will not fit a standard King bed frame. Please measure your bed frame before ordering to ensure the correct fit.

Just What I Needed!
Color: Copper & White
Size: Twin
Set name: 14-Inch
I was skeptical when searching for a mattress online. How could I be confident that what I purchased was made for my comfort. I was drawn to the idea that a mattress could have copper qualities so I ended up buying this Copper Smart mattress. It arrived shortly after I ordered it and it was easy to unpack and after sleeping on it for a few weeks now I can’t say how much I love my mattress. It’s not too hard and not too soft, it is just what I needed.

Nice mattress, don’t hesitate to buy!
Color: Black
Size: Full
Set name: 8-Inch
I’ve owned this for about a month now. It arrived fast. The mattress came in a box that is about 10”x10”x5’. It’s tightly rolled, with a couple layers of plastic to keep it tight and clean. I live in the PNW and it arrived at my back door very early in the morning while we were getting quite a bit of rain. We brought the large awkward box in, opened the ends to see if it was wet (it was sitting on one of the ends in a small puddle) to discover it was nice and dry. We left it for a day to dry out the box. As this was going upstairs I wanted to be able to carry it up in the box as I wasn’t sure if it would unfurl if we took it out of the box. We carried it up and pulled it out. It stayed nice and tightly wound. We started to remove the plastic and to roll it out flat. As soon as we did it started to expand. We let it do it’s thing and it filled out quite quickly. There was a very slight manufacturing smell, as some folks on here described, but considering this has been tightly compressed inside a box for who knows how long, it’s to be expected. We plopped it onto the futon frame, in the couch position, and it snuggled in quite well. We sat on it (2 people) and it was quite comfortable. The slight smell dissipated within a day or two. Mattress has stayed in place perfectly. This was purchased for my home office, which can be used as a guest room in a pinch. I have stretched out on it a number of times and it’s quite comfortable. I have not fully opened the futon as a bed, but know it will be fine. It’s the perfect reading spot which means it’s perfect for a nap! It’s quite firm. Absolutely pleased with this mattress, would definitely purchase again. With the quality of this mattress I don’t think I’ll have to for awhile. The cover it comes with is very nice, but I’m a firm believer in keeping a removable washable cover on your futon. The mattress has buttons on it. If you have longer hair, it hurts if your hair gets caught on one. I also recommend the mattress protector. I have dogs and cats and the protectors will substantially extend the lifetime of your mattress. Don’t hesitate to buy, it’s a very nice mattress.

Very comfortable!
Color: Black
Size: Full
Set name: 8-Inch
I really like this mattress and definitely recommend it. It is very supportive and comfortable - for both sitting and sleeping. It stays on my frame just fine and doesn't slide down (mine is wood). You don't feel the futon frame underneath, and it isn't noisy. I had another innerspring futon mattress that was very hard, and if I had to sleep on it for more than 1 night, my back would hurt. I only gave 4 stars because I ordered a black one, but got a brown one. I ended up keeping it because it matched my decor ok, and I didn't feel like dealing with the hassle.

First Night Impression + Update
Color: Black
Size: Full
Set name: 8-Inch
First off, I received the mattress in excellent condition; no damage to the box or the product inside (thanks to the seller and UPS). On the day I received my mattress, i removed it from the box and left it rolled and wrapped it plastic. After a quick inspection I could tell there was no damage to the plastic wrap and the mattress was intact. The next morning before leaving for work, I deflated the air mattrrss this was purchased to replace and unrolled my mattress on the floor. I removed the plastic wrap. After the first cut into the plastic you can hear the air rushing in as the coils slowly expand. As I made the hole larger, the mattress expanded faster. By the time I fully removed the plastic, the mattress was at full height (8”), but I left it there on the floor and went to work. When I returned home that evening, I measured the mattress again and confirmed it was fully expanded to eight inches. My plan was to remove the cover and take it to the laundromat, then wrap the mattress in a waterproof bedbug protector cover. Although the cover is removable, the plastic tabs that make the demples in the surface go straight through to the under-side of the mattress and through the cover. I re-evaluated my plan. The cover is clean and there is no smell coming from it, so i wrapped the mattress with cover in a newly purchased and washed mattress protector, then threw some fresh sheets on top. I ordered my frame separately, so my first night was on the floor and after some ‘starfishing’, I passed out. I slept so well, I didn’t want to get out of bed this morning! My impressions of the mattress is it is firm, but soft at the same time and easily gives to my 210 pounds, without dipping in the center like foam and air mattresses tend to do. I love it after the one night. If you are looking and are on the fence, know that I whole heartedly recommend this mattress and do not regret it. [UPDATE] I did decide to cut the plastic tabs and remove my cover. I didn’t wash it because it says to “Spot Clean Only” on the inside tag. I went ahead and placed my mattress protector around the mattress coils, then placed the cover back over the mattress. This was important to me because I also purchased a roll of Futonland No-Slip strips. It grips the black cover better than the loose mattress protector I originally placed over the whole mattress. On top of the cover I used a quilted fitted mattress pad from Utopia Bedding. It easily stretched over the whole mattress and adds an additional layer of foam on top of an already super comfortable mattress. Sheets and blanket next, then I ‘starfish’ myself to sleep. 🙂😴

Best in Class
Color: Copper
Size: King (U.S. Standard)
Set name: 14-Inch
We were visiting friends for two nights and slept on this Roost Sleep mattress in their home. We had the best sleep and woke up with no pain. We are in our sixties and always have pain. We have never purchased a mattress through the Internet, always at Macy’s and for thousands of dollars. We found this Roost Sleep King mattress on Amazon and it was only $719. It arrived in a box and it was easy to open. I’m not one to write reviews on products but I had to write this one. It is without any doubt the best mattress I have ever slept on. If you need a mattress at a great price, this would be my choice.

This mattress is very comfortable. I have had a foam mattress for many years and I just upgraded my side of the bed. This one did not have any gassing off and inflated very quickly. I have a bad back and this helped a lot. I would highly recommend it
