The Mediwedge arrived at 2 PM. I opened the box and followed the directions. At a little after 6, I put the MW under my mattress and made the bed. Went to sleep at 10 and slept like a log. It really is a wonderful product and not just an old piece of foam rubber. I particularly like the neat and clean zippered cover which can be cleaned with a damp sponge if ever it is needed.
