This bed arrived three days after the purchase. On the first and second night I was acutely aware I was lying on a different mattress. On the fourth night, pain in my lower back stopped, but I developed pain in my upper back. After 11 days the pain was worse. I was told by Ghostbed that I could not return the mattress until day 30. So, I persisted. On day 17 the pain in my upper back was gone and the mattress began to feel very supportive. I am now at day 27. I am not going to return the mattress. It appears to be correcting my posture. I feel more rested after shorter periods of rest. I recommend sleeping on the mattress for at least 30 days before making decisions. By the way, I have a big Boxer called Willbur. He weighs 80 pounds and I cannot get him off this 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!!!

The bed started out a little stiffer than what I was used to, sleeping on a mostly-spring mattress my whole life. The memory foam aspect got a couple days to get use to, but I was soon accustomed to it. 3 months after using this mattress, I can surely say that I've found better sleeping experiences in lieu of my previous mattress. The product lives up to its stellar quality well.

We purchased this bed approximately six weeks ago and so far it is working for us. We went with the hybrid mattress but it does seem firmer than we thought it would be. Maybe a little too firm. We added a pillow top mattress cover and that helps. My wife loves the adjustable frame.

From ordering to delivery to unboxing, everything is so simple. The flex hybrid mattress is a bit firmer than we prefer, but we are sleeping better than on our very old and softened mattress and with fewer aches and pains. We are strongly considering a foam topper to help ease the firmness. We bought two twin xl to use as a split king with the Ghostbed adjustable frame. The adjustable frame is life changing!

Bought the bed after hearing about on The Antihero Podcast. After further researching the company we ordered the mattress. I sustained back injuries from Iraq and longevity of being the military. There was not a day that went by that my back was not stiff I was not in pain. I can wake up now minus the stiffness and my pain, minus things that can’t heal, don’t bother me. Great product.

I purchased the flex using katupult. Which makes it a easy way to purchase. The bed arrived a few days later after my order. Unpacked it and let it air out some on my bed frame. It was a little firmer than I wanted it to be but after breaking it in it's worth every penny. I've slept great on it every night since I bought it.

Very firm yet springy! Has the sustained support that my back needs. It feels firm all the way across throughout the night without the dreaded sag towards the middle. I am a very warm sleeper and have found that this mattress does not heat up to an uncomfortable level, I definitely recommend!

I like the hybrid style. After years of sleeping on all-foam mattresses, it's nice to have some bounce. My husband and I are average weight, but our last mattress was not supporting our hips anymore and this mattress has us both feeling so much better. I like a firm mattress, and this is it. It does transfer more motion than an all-foam mattress, but it's a fair trade-off.

Just got our ghost bed flex two weeks ago and so far my wife and I are enjoying it. Still adjusting but chronic pain in my shoulder has gotten better and my wife is very pleased. Med to med firm seems like a fair assessment of the feel of the mattress and so far it hasn’t slept too hot (although it’s still winter here in the northeast). Shipping and setup were easy and quick. So far it’s been a very good experience.
