Product reviews for Wedge U- Shape Orthopedic Cushion

I ordered Wedge U- Shape Orthopedic Cushion,  Foam Type: Luxury Firm Foam, Beige Knit Terry Velour Cloth,  Height: 16" x 18" x 2".    Perfect for my recliner.  It is hard to find a 2" high wedge.   The cover is not removable for washing and seems overpriced at $20; it's just some velour terrycloth.  The firmness is just right.   I can't compare foams because I haven't tried the other one.
