The rug is wonderful---but I have to ask ??? have you tried putting a bar of soap under your bottom sheet, just a little above where your ankle would rest? I make a small cloth pouch to put it in and pin it to the mattress pad) DH says it works...in fact, just made a new pouch for a bar tonite (he went to bed and I had forgotten to put one back after changing bed). Only other addition I can give you is "square" bars seem to work best.
