Back pain instantly went away on my first night sleep on this bed! We went from a Queen to a king and I will have to say it's the best thing I've ever done for my relationship. Nobody touches me and it is great. We still co sleep with our toddler and he doesn't even touch me now.

Mattress is quite impressive

It was for my guest bedroom upstairs which my eldest daughter slept in for the first time last night. I recently had a hip replacement so I couldn't go up and try it myself. She said it felt great. She said it was one of the most comfortable beds she's ever slept in.
