My doctor suggested a wedge pillow when I began using a CPAP. This one seems to do the job. I worried that I would feel the transition between the pillow and the bed sheet and it would feel like a lump in the sheet that I would always want to smooth out. but that hasn't been a problem. The pillow case is rather flimsy and I know I'll need to make another. I wish companies that make unusually sized pillows would include a pattern or line drawing with dimensions for those of us who are relatively novice seamstresses. I sleep fine on the pillow. I put my regular pillow on top of it so it is more of an extension of the mattress than it is a pillow. It works fine with the CPAP hose. I do tend to slip down on the wedge as the night progresses. . . . .It arrived quickly and in good shape, as I've come to expect from Overstock.com.
