Comments about MabisDMI Deluxe Swivel Seat Cushion:

This is a high-quality product as far as appearance, construction, value, etc. But it may be too "high" for you -- as in the height it adds to the user, so that their knees don't fit under the steering wheel comfortably. I bought this as a gift for my mom and she could not lower her Camry's seat enough, or raise the steering wheel enough to accommodate the amount she was raised up when sitting on the cushion. (Then her arms were uncomfortable at the new angle of the steering wheel.) I'm hoping they'll let me return it . . . If you have a newer car, they make the seats more adjustable these days, so you shouldn't have any problem.
