My wife and I sleep hot and we are trying to find something that keeps us cooler during the night. After reading a lot of reviews we decided to give the Ghostbed Flex King a try. This is our second try at a bed in a box. After setting up the bed we gave it a full 24 hours to expand. Now the test. The flex felt nice and cool the first night that we slept on it. Each night since then, it doesn’t feel as cool anymore. We have been sleeping on it for a only a few weeks. We were also used to sleeping on a softer bed. The flex is a bit firmer than we are used to but are slowly getting used to the firmer feel. Will be ordering the ghostbed mattress protector to see if maybe our current one is the cause of the problem. Overall happy with the mattress so far.

This bed is fabulous! It's not too hard nor too soft for us. We had a Sleep Number bed that just never felt that great but due to the cost we tolerated it. It's super thick at 16" deep and is extra long for us tall people! You'd never be sorry unless of course you like a very firm mattress!

I was really looking forward to this mattress. I have had numerous back, neck and shoulder issues over the past year and knew it was time to start looking for a new mattress. After the Texas Freeze I ended up needing to replace my mattress sooner and ultimately chose this ghostbed flex. I took about a week longer to arrive than originally quoted so a lot of sleeping on the couch. Once it arrive I unpacked it and let it sit for a day then added the bedding. First night sleep was great. After about a week no back or neck pain. Love the mattress. The ghost pillows are great too but initially have an awful smell. The smell went away after a week.

Very comfortable, we love it! We had a memory foam mattress before and it just didn't provide enough support. This mattress is comfortable but firm enough to support us during the night. It is cool but not cold, so the spot you sleep in doesn't get hot. Highly recommended.

I had to give my mattress a few nights of sleep before doing a proper review. Well, the results are this...I’ve fallen asleep faster than I’ve done with my new mattress. Plus, I’ve slept soundly ALL night! I’ve not gotten hot while asleep, & I couldn’t be happier with how well rested I’m feeling the next morning.

The bed is just what I needed. I have a bad back and acid reflux. The adjustable frame allows me to raise my feet up when my back is aching and I can raise my head up with my acid reflux. There are so many features on the frame as well like a phone charger and underbed light. I chose the Flex mattress. It is the most quality mattress I've ever owned! They also gave me 2 of the best pillows I have ever owned. What puts the icing on the cake is they also have the best customer service!

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.

Ghost bed flex is not a medium firm mattress! It is way way too soft. You sink way down in the mattress. I only weigh 135 and cannot even move around it sinks so badly! I would only recommended as a soft mattress for people that want a very soft mattress. I contacted them over two weeks ago and they have not responded back to me!!!

It is not a great mattress. I live in a high humidity climate and wake up every single day from being hot and sweating. My house is at 67 F! I sleep just fine on my guest room mattress. The ghost mattress traps heat! I hate it! As for motion transfer - I feel my partner move. Save your money!!! I would not recommend.

This is the best mattress I've had in my life. As comfortable as a full memory foam mattress, but feels more supportive with the wrapped coils. Highly recommend this mattress and I will never buy anything different. I'm a side and back sleeper-perfectly comfortable either way!
