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.

Since sleeping on the GhostBed flex hybrid mattress for the past month I have been waking up with fewer body aches. This morning I noticed I had no pain in my joints when I got out of bed.

My wife and I have had this mattress for 6 months now and have slept so well. We have been looking for a comfortable mattress for a long time and are pleased with this mattress. It is pricey, but might as well invest in your sleep.

I do like the flex hybrid bed a lot. My husband says it is a little on the firm side, I think it's just right. Seems to cool ok, but I still wake up hot most nights. I am satisfied with the purchase and would buy again.

I don't love it as much as I was hoping. It certainly is a step up from our old mattress. It's harder than anticipated. I don't notice my husband moving as much. It is much cooler.

I absolutely love this mattress! At first, I thought it was too firm, but I soon realized that it was the perfect firmness for my body type (heavy person). Definitely a purchase I stand behind.

This was my first time purchasing a mattress without laying on it first. I am very pleased with it matching my expectations from its description. No lingering chemical smells. I find it very comfortable.

It takes a little to get accustomed to a new bed, so far we are very pleased with our choice of the Ghostbed Flex, we are going to look into the Ghostbed mattress cover for this bed.

Absolutely the most comfortable bed I’ve ever slept on! I originally bought it for my husband that has a herniated disc but my minor back pain has lessened also!! We love it!

My GhostBed flex is so comfortable, no more back pain when I wake up and it’s also nice not to feel my husband tossing and turning throughout the night
