Review: Good product - Bought this for my son's bed who has trouble with reflux. It has help him.
Review: Happy with my purchase! - I’m glad I bought this! No off-gassing for me and I have an annoyingly sensitive nose. Excellent quality, no sagging, no slipping as others have stated. I do have a bedskirt that is more like a legging, if that makes sense. It’s a knit fabric that goes around my box spring, like in a hotel. It’s big enough that it also covers this wedge. My only wish is that it was a little higher.
