PLUSES: Twin XL is extremely comfy. Sleeping deeply in various positions. No rattle or moving when partner gets up or moves. Xtra functions are a benfit (Raising / lowering head and feet area, massagers, etc.) MINUSES: The gap between two twin xl's is actually more of a gulf with no way to really close it. It does not feel like a king bed. Bit soft around the edge of the bed when sitting on the edge of the bed.

Wife and I really enjoy the bed, she’s a side sleeper and I’m a stomach, seems to work good for both. It is a bit firm if you don’t have enough weight to take full advantage of the beds construction. Edge support is excellent. Shipping was fast, easy setup, no complaints.

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!

My last mattress was a sleep number and I didn't like it, woke up throughout the night tossing and turning and waking up in pain. I was hoping my new mattress would make me feel better, I don't toss and turn as much but I still am hurting when I get out of bed. The flex is not working for me and that is the one that was recommended. I sleep on my side and back. I been sleeping on this mattress since dec 27, 2024.

The setup out of the box was a piece of cake. Easy to take out and roll right across the platform. The softness of the bed was really weird for the first week. You definitely have to give it time to get use to. The flex is nice but very soft. I may have been better off getting the matrix being it said it’s a little firmer. Who knows maybe another review in the future.

I cannot say enough amazing things about this King size Flex mattress! Perfect does not begin to describe it!!! My wife has a few autoimmune illnesses that sleeping very difficult, as well as have crushed/herniated/bulging discs in her back. She usually tosses and turns all night, and wakes up in excruciating pain. The first night she slept on this bed, she had the most peaceful sleep of her life she said. A few weeks later, and it still holds true. She wakes up refreshed and recharged, and her pain has subsided significantly. She is so shocked and happy, and that makes me happy. I also have some issues with sciatica, and would wake up from muscle spasms and cramps. I am a local truck driver, and make a bunch of stops per day loading and unloading trucks, and typically work a 12 hour day. I used to be restless at night as well, and ever since we started sleeping on this mattress, I wake up pain free, have not had any spasms, and am ready to start the day. This truly is/was the best purchase I have ever made! Wish we wouldn’t have been so skeptical, and would have done this sooner!

Took me 7 days to adjust to this mattress, but now I wouldn't give it up. Great night sleep, don't want to get out of bed, not hot sleeping, just comfy cozy. We bought the split king with adjustable beds to go with it. We love out Ghost Flex Mattress & adjustable bed. Wonderful quality & workmanship, hard to believe it came out of a box!

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.

I have went thru several mattresses before trying this one. My back no longer hurts and I don’t struggle to change sides anymore I haven’t slept like this since I was a kid! I am 6’ 7” weight 308lbs and this supports me and I wake up well rested! Great price for the King also! Bad sleep buy the Ghostbed flex!

My husband is a hard mattress guy and I like softer mattresses. I was worried this would be too soft for the hubs. We have had this mattress since middle of Jan 2021 and are still loving it. The memory foam makes it feel like you sink in but you still have support because of the springs. My husband always sleeps hot and this mattress has cut down on the amount of sweat tremendously, even with the protector on.
