I sleep on my back and this thing is brutal. I can never get comfortable and lower back is sore every morning. Lesson learned... Never buy a mattress online to be delivered in a box.
My husband ended up sleeping on the couch every night from his back hurting from our old Mattress (He is only 34, but did 8 years in the service.) He heard of Ghost Bed on his Pod Cast, Drinking Bros. We could not be happier with the buy and the pillows. 100% reccomend.
The mattress took a few nights to get used to but after that, it was great. It doesn’t really sleep any hotter than my old coil spring and it’s uniformly supportive.
I wasn't sure about the bed until I slept in the old bed for one night. I had horrible pain in my legs in the morning and all the next couple of days. My husbands loves it and I guess I am a believer now.
