    • Comfortable mattress

I had the pleasure of upgrading my son’s sleeping experience with the Twin Mattress 6 Inch Charcoal Memory Foam Mattress, and it has truly transformed his nights from restless to restful. From the moment I unboxed it, I could tell that this mattress was going to be a game-changer for sleep quality. The 6-inch profile is perfect—not too thick and not too thin—offering the right balance of support and comfort. It's constructed with a top layer of memory foam that contours to the body, cradling you throughout the night for optimum comfort and support. The addition of charcoal within the memory foam is a standout feature. Not only does it help in regulating temperature, keeping you cool and comfortable all night long, but it also plays a crucial role in repelling odors. This has kept the mattress feeling and smelling fresh since day one, enhancing the sleeping. The mattress also comes compressed and rolled in a box, making it incredibly easy to set up. I appreciated how it expanded to its full size quickly and without any hassle. Its firmness level is just right, providing the necessary support for my back while still being soft enough to feel luxurious. Overall, the Twin Mattress 6 Inch Charcoal Memory Foam Mattress is an exceptional product that delivers on its promises of comfort, support, and durability. It has improved my sleep quality dramatically, and I would highly recommend it to anyone in search of a new mattress. Whether you're dealing with back pain, sleep disturbances, or simply looking to upgrade your sleeping arrangements, this mattress is sure to exceed your expectations. ... show more

    • Comfortable
Size: King Style: 12 Inch
Ordered this mattress because I found it ridiculously expensive to do so in person at stores, any memory foam mattress I was looking into was over $1200+ and I really did not feel like spending that much, I tried this one out hoping I would like it first try, I loved it. The whole reason I picked this one out of the other ones I saw on here was because of the no fiberglass thing, I did a lot of research on the memory foam mattresses amazon had to offer and the reviews for the majority of them complained of fiberglass even though they advertise no fiberglass, it’s a very dangerous component to a mattress if leaked out so I was scared which is ultimately why I chose this one, Instead of the harmful fiberglass it has another layer of protection in place of that and the actual mattress itself is very soft, it’s not too soft and not hard either so it’s perfect for me at-least. I love it. ... show more

Just received yesterday. Great price if gives us comfy sleep. Purchased California King to fit the fream amd it is a snug fit. Put it in place, decompressed pretty quickly but letting it set per recommendations. Put in place before unwrapping. Will provide update after use. Please excuse the mess. Moving furniture around. Update: have slept on it for the 1st night. Love it. I was going to wait longer to review but my husband loves it. He has chronic back pain. It decompressed to the full 14 inches by bedtime. It fits tightly in the watered frame. Very pleased. Update: We have slept on it now for a couple of months!! WE STILL LOVE IT!! Firmness is just right, great support in the hip/bottom area. Motionless, my hubby and dogs can move and I don't feel it. I still recommend this mattress. I have not needed the same support from my pillows as with our older mattress. I sleep with only 1 pillow now. No sinking on the edges, inflated to just over 14inches. ... show more

Size: King Style: 12 Inch
So far this is a nice mattress. Isn't too soft or too hard. I deducted two stars because I ordered a 12 inch mattress and it only inflated to about 10.5 to 11 inches in some spots. I guess I should of got a 14 inch so it would at least be 12 inches!!!!

The media could not be loaded. This mattress came quickly, inflated in less than 2 hours without a smell. It’s lightweight and a true twin size mattress.
