I have had my adjustable bed frame about 3 weeks now ~ I absolutely love it!!! I struggle with edema (water swelling). Every night I just elevate the foot of the bed and I have not had much swelling. ~ I have breathing problems. Laying flat was always difficult for me. Now I can raise my head however far I want. ~ The message and light features are nice extras. 
The only issue was with customer service ~ I ordered a King (which is two twin XL's) I only received one twin xl. Customer service ended up cancelling my order and told me to reorder. I reordered and again received one twin xl. ~ When I called customer, service they acted like they could case less.
