DeepSeats are available in sizes 12 thru 18, in half size increments. The seat “size” is the width of the seat (in inches) at the very top, where is sits just below the driver’s armpits. To measure yourself for a seat, have someone measure the width of your back at the approximate height where your seat sits. Add 1/2 a size if you wear a rib vest. A size 12 would be for a smaller junior driver weighing in at under 100 lbs. A size 18 would be for a larger senior driver weighing in at over 250 lbs. We can help you select a size when you call or email.

The seats range in price from $275 for a size 12 to $310 for a size 18. The price includes standard UPS shipping.
