I really honestly can not live without mine, bought it about 5 years ago because my backpain and swollen legs, since then Iāve had to spend the odd night in a normal bed and Iām in so much pain and legs and feet so swollen.
I use fitted sheets, buy extra deep ones, and theyāre fine. Itās so lovely to adjust it to watch tv in bed and be pain free, itās so comfortable my husband bought one even though heās as fit as a fiddle! You can get them as 2 singles that lock together and work independently to each other.
The only thing I will say is remember they are slightly bigger than a standard bed, and the frame is solid and heavy. In my old home the men struggled to get it up and down the stairs with a bend in, and weāve now moved to a bungalow and they couldnāt get it into the bedroom I was going to use, just couldnāt get the turn room ( tbh it was a blessing in disguise this room is the better one in hindsight)
