This mattress is very comfortable. Firmness is medium (not too hard, not too soft). When you lay on it, it sinks a little but supports the body well. There is no problem turning, you don't feel like being stuck. Comfortable for side, back sleeping. I think it is also OK for stomach sleepers, the firmness is sufficient. If you are sleeping with another person, there is some movement but it is reasonable. I would not qualify this mattress as super cool, but I guess that a mattress cover and sheet tend to reduce the cooling effect. The only disappointing thing, is that if you sit on the edge, you kind of slip off. Even though the spring section is reinforced on the edges, there is still about 4 inches of foam on top and I believe it negates some of the spring reinforcement. I would qualify this mattress as a good mattress.

I love our ghost bed! Got the flex after doing some research for a much needed replacement. I was worried it would be too soft since I was looking for firm support but it is perfect. I have had chronic back pain for years and I finally feel relief when I sleep. Also was super easy to set up.

Just received the bed not too long ago but the first couple nights have been amazing! I was using an old spring mattress before and this is a major upgrade. It is a little more firm than I would prefer but still comfortable. Wish I could sleep all day!

Absolutely love the flex mattress, my husband who sleeps hot as the time s now cool in fact he put a cover on the other night - it shocked me as he usually sweats and complains about being hot - meantime I'm freezing. He a has a lot of pain in his neck and back now he doesn't even notice that pain is gone in both his neck and back. Even after a long day mowing as we call it the back forty he gets up the next day. Me I just love our twin extra long mattresses, because of surgery I have to sleep sitting up and even that is more comfortable for me as I get the support of the individually wrapped coils but the cushiness of the top layer. Obviously we are both in love with the mattresses.

The bed is ok. The mattress is not any more comfortable than the one that was replaced. The massage is more like a vibrate. I do like that I can set it to read mode, sleep or zero gravity. Set up was very easy; I did it myself. I would recommend if you have help, definitely use it. The base is very heavy.

The first night on the Flex I slept 7 hours, and that’s really good for me. My wife slept better but thats normal. I’d give the Flex 5 stars but I still get a little hotter than I had hoped. Probably not the beds fault, I wanted to go with the Luxe but a have a prosthetic leg and decided to go with the Flex because of the side stabilization. That seems to be working good. So far, after a number of weeks sleeping on this mattress I believe I made a great choice. Thank You to the Ghost Bed Team

The bed is so so soft . It keeps cool throughout the night. I have been getting alot more sleep than i did in the past. Worth every penny. And yea its so dangerously comfy that i have trouble getting myself to get out of bed. I no longer have aches or pains when i get up. The sheets i got from them are really nice the pillows are about as soft as the bed. I would like to see ghost bed to do their own blankets and comforter sets i bet those would make it even better

I slept in a Ghost Bed mattress at the Lizzie Borden House when I was on an Investigation Vacation & I immediately knew I had to have one! I was literally in the airport on my way home when I placed my order. This has been the best mattress I have ever slept on, I also ordered the Ghost Bed Memory Foam Queen pillow, I no longer toss & turn at night. I suffer from migraines a lot, I usually wake up with them, but ever since Ghost Bed & pillow I haven’t woken up with a single migraine or neck ache! I would give this 10 stars if I could, it truly changed my sleep life!

Although this bed is great for me, it didn't seem to work well for my wife. She particularly didn't like the top cover material. I added a mattress cover on it which seemed to work for a week, but then she was not happy with the "sink in". I think this bed is great for people who like to sleep in-bed vs on-bed, if that makes sense.

My son moved out on his own and I bought this mattress. He absolutely loves it. I just bought another for myself and agree! The all in one foundation is amazing and such an improvement over the previous wooden ones. I easily attached a headboard to mine.
