I have a King size Tempurpedic mattress with an adjustable base & remote control.(It even has massage mode. (Image for display only) It's about seven years old but I have not slept in it. I have a disability that doesn't allow me to sleep horizontally so
I have never been able to sleep on it. I know that it will make an excellent addition. The adjustable base with remote allows you to sleep at the zero gravity position or upright for watching television.
