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.

My back doesn't hurt anymore like with my memory foam mattress I absolutely love this bed just wish the all in one frame was taller(I ordered more legs) and bed a little more soft The pillows are amazing as well All in all I've very happy

This is a fabulous bed. We ordered beds from Helix and it was too hard for me. My flex Hybrid mattress is perfect. I am able to sleep on my sides for the first in years. I highly recommend this mattress!

Comfortable bed! Would not recommend for anyone who is a restless sleeper and moves around alot. Quite bouncy when Someone else is moving or getting out of it. Easy setup.

Provides the right amount of support where you need it. Not to Soft and Not to Firm. Amazing what a difference an awesome bed makes for a great night's sleep.

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.

Delayed shipping too longer than expected, Communication about that wasn’t great, but this bed is so comfortable, so it’s worth 5 stars. Great value for the money. I have a herniated disc and I sleep like a baby.

So farwe like our ghost bed . its comedy..I like how easy it is to turn over without disturbing my husband ..its exciting to sleep better ..it was a problem with our other bed ...

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.

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!
