I am a big girl, 250+ and my old mattress was just too soft to give me any comfort. I would wake up with back and hip pain. A memory foam topper (from this same company) brought a little relief. Was so excited to get my Ghost Bed, and then I came down with the Flu. I was in bed for many many hours due to being ill, and I didn't get achey and sore from laying in bed too long. Even my husband is loving it. He is having trouble getting out of bed in the morning because he is so comfortable. It does take a little adjustment, especially when you are coming from a pillow top mattress, but I wouldn't trade in my Ghost Bed now!
I would recommend trying GhostBed. I must admit I am not a raving fan as I do not find it "Supernaturally Comfortable" however It is as good a mattress as I have ever slept on. It is definitely a heavy mattress but I am hoping that is indicative of a mattress that will last a long time.
When I first got the bed it seemed very firm. It's breaking in more now but it's still not as soft as other reviews made it seem. It's starting to break in though.
I liked how easy it was to setup. However, I thought it would make a big difference on how I slept. We have had it about a month now and can't tell the difference. I think we are going to return it.
The perfect balance between firm and soft. It feels like it's made from very durable materials. Definitely worth a try, especially since they give you 101 nights to do just that. What's to lose?.. except a good night sleep.
