I bought this cushion to relieve pelvic pain associated with spondylitis. The shape memory foam provides extra comfort to work at my desk. It penetrates well but still firm enough cushion provided. The coccyx area is clear and well dished following anatomy. I associated with lumbar cushion of the same brand that is as good (but the colors are different, this one is old rose, the other burgundy).
The cover can be removed for cleaning.
For that price, an excellent product because most seats foams of this quality are usually much more expensive.
