The mattress miraculously expanded more than I anticipated. My old latex mattress & adjustable bed was 12 years old. The crease where my bottom laid got deeper. I was going to just replace the mattress only & keep old base but realized the Ghost Flex Mattress was almost 2 inches wider so I ordered a new base too. I have lots more room. The adjustments are perfect. Pressure points don't ache any more. Love the vibes & under bed light. I'm in my 60's & plump, the Flex holds me quite well. My husband & I each have twin XL beds pushed together to form a king. We each have very different positions. He kept his old bed. Bet he'll change his mind soon.
The base is good for elevating the upper and lower body, the massage is great too but lately it sounds like it's going to die and I've only had it about 2 and a half weeks.
Has all of the basic features plus a few extras. Quiet motors and wireless remote. Would prefer a solid foundation (versus wire-frame) but it gets the job done.
Sleeping with my head elevated has really helped my rest at night. Also, love the night lite feature for getting up in the middle of the night and being able to see without turning a lamp on and disturbing my wife.
