Both great products but I only wish there was an in-between firmness between the two models. The Original GB is great, very firm, almost a 7/8 in firmness. The Flex is 5/6 in firmness.... If it were a 6/7 I'd be thrilled, but it's still a very cozy bed.

Most comfortable bed I have ever slept on! Thank you, such a great design and functions so smoothly when raised or lowered at head and, or, feet! Purchased to use during recovery from spinal surgery and this amazing bed makes getting into and out of bed ten times easier than my other bed! Also the Zero Gravity setting makes my sleep almost pain free after my huge spinal surgery.... Thank you so much! Jeff

Love the mattresses. Very comfortable for us. The All-in-one foundations are great - but there are errors in the assembly instructions - figured it out fine but some may not. Customer service - well it was good just very slow. COVID I am sure is partly to blame. We had defective foundations (wooden ones) and they replaced them with the metal All-in-one foundations. We didn't even have to send them back. Well done (just took a few weeks of waiting).

I slept on a twin pillowtop my whole life until i got myself a King Ghostbed Flex. It is wonderful. So soft, so cool, so comfortable. Easily the best sleep of my life. The foam top is super comfortable and you dont sink inside of it! (I have had it for about 6 weeks now)

Best bed ever sleep better and sounder than other beds the frame being adjustable is great have it lowered for my wife’s height easier for her to get in and out the ghost sheet set are a must to get they stay put even if you move around a lot at times. Worth the money

My partner and I have very different sleeping preferences but this, absolutely, has made a world of difference towards “meeting in the middle”. We upgraded from an older queen mattress so the roominess is absolutely wonderful, as is the feel of the mattress itself. We waited to see how we felt about the mattress before we went towards purchasing the base but we’re so excited to add both to our home. The pillows are some of the best I’ve ever felt, but I’m able to sleep with or without a pillow on this dream bed!

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!!!

I spent a considerable amount of time reading consumer, semi-pro, and professional reviews on current beds. I settled on this Ghost Bed Flex and have experienced great sleep while reducing my back pain and overall lesser aches in the morning. This is an awesome bed, and I would buy again.

Set up easily. We struggled to get the frame boxes up the stairs then decided to take them out of the box and it was much easier to handle them. We've been sleeping on the mattresses for 3 weeks and are very comfortable. We have twin XL. My husband is 6 ft 1 and he does slide down with feet hanging over when raising the back. Hopefully when the mattresses break in a little more they will bend with the frame and reduce this situation.

I am in love with our new Ghostbed. Been looking for a while and decided on this bed after a good friend got one and loved theirs too! I have a lot of hip and back pain from an old accident and from the first night I slept all night and honestly did not want to get out of my new bed!!! Excellent product! Thank you so much!! I’m a Ghostbed customer for life!
