Nice riser that matches the other equipment in this family
This is the same dimensions as the large foam block with the same nice cover;  2" thick.  As I write this the foam block is out of stock so I am using it on top of an ottoman for now and it works great for my Egoscue exercises.  I can see it working well as seat cushion or knee pad also if the dimensions fit the need.  I would say the foam density is mid level;  not super soft or hard.
