Love it but cover is slippery
This is the best seat cushion I have found for long days at the office sitting behind a desk or long road trips in the car.  The only negative is that the cover is slippery and the cushion moves a lot on my chair when I scoot or adjust my seating.  I have tried leather chairs and fabric chair and the cushion does not stay in place well.  I am thinking of adding velcro strips to the sides to attach it to my armrests.  Other than than superior comfort, just slippery.  Highly recommend.  Has helped my posture and back pain.
