the cover with the cushion does not work to keep it from slipping around - maybe it would work better with material seats instea
I bought this as a seat cushion for my weekly 4 hour commute and had high hopes, but unfortunately, Purple is selling snake oil for a cure-all.  It does not do as claim - provide no pressure.  Instead, it is actually more uncomfortable then my regular car seat.  the cover with the cushion does not work to keep it from slipping around - maybe it would work better with material seats instead of leather seats.  I would not recommend purchasing if going to use on regular basis, sitting for long hours.
