This is a great quality swivel pillow for my mom’s kitchen chair. It has wheeled bearings and make it easier for her to turn around and get up from her kitchen-/dining chairs. Very comfortable to sit on and my prior purchase lasted several years with daily and fairly heavy use.
Real nice swivel seat. Smooth swiveling for getting into or out of the car. Stays put on the car seat while driving. Sits about three inches high, which might motivate you to lower your car seat. Fits better on a flat car seat, as opposed to a car seat that has contoured edges on either side of the hips. The swivel seat still works fine on contoured seats, though; it just doesn't sit quite flat.
It helps me to get out of my car especially when I need a knee brace.
