For someone who doesn't have back problems the Flex would be perfect. It's comfortable, soft. However, you sink around 6 inches. If you are a restless sleeper it will keep you in the same place causing you to wake up.

Third time really is a charm! After trying sleep number and loom and leaf and not sleeping and being so uncomfortable for months with both we landed on this dream bed and sleep has never been better!!!

Comfortable, cool, and firm but not hard. Decent price compared to other brands and quality is as good or better than some of the more expensive brands we tried in stores. Super easy to setup!

This mattress is very comfortable! It is a little softer and not as cool as we anticipated, but needless to say, we are sleeping well and very comfortable!

Very comfortable bed. I had anticipated the sides having a little more rigidity to them. All in all, it is a very nice mattress which provides a pleasant night's sleep.

I have had the deepest sleep I have ever had after purchasing and sleeping on my GhostBed flex. It is wonderful. Easily the best sleep I have ever had. It sleeps very cool as well. Excellent purchase. You can’t beat it for the price!

I like the mattress a lot. And my back pain is gone. However, i have used memory foam for last 10 years so the bounce in this mattress is something i personally am adjusting to. I am thinking about split king version!

I love my new bed. I haven’t slept all night in years as I have lower back issues. I’m not saying the bed fixed my back, what I am saying is I can finally sleep even with ongoing back issues. Strongly recommend GhostBed Flex.

Love our new Ghostbed. No longer am I waking up hot. No back pain and a great sleep. Such a comfortable mattress. We definitely made the right decision. No regrets.

The GhostBed Flex is a bit less firm than I usually like, however, I haven't slept this well in a long time. I sleep in a cool comfort that is so much better than our previous high-end mattress. I am so glad we purchased the GhostBed!
