Our Orthopedic Booster Seat Cushion boosts you up comfortably in your seat. Shorter drivers can see the road better both ahead and behind their car. This cushion is the best we've found, and like us, you will wonder how you ever did without it. ur Booster Cushion lifts you about 1 1/2 inches, and reduces the pressure on your spine. We have been using ours for several months and it still has kept its resilience and support-ability. The extra 1 1/2 inches lifts you quite a bit. My wife is 4'10" and it boosts her high enough for driving.    Although the cushion is especially helpful to shorter drivers because it boosts you up, it also is comfortable for drivers up to about 6 ft tall (like me) and still doesn't raise them too high in the driver or passenger seat. These special cushions are also just plain comfortable, and can be used by anyone who needs to sit for long periods, short or not. This cushion can make an uncomfortable seat into a very comfortable one, especially if you have to sit on hard surfaces, such as benches at sporting events, camping, or church pews. I tried mine on a long airplane trip recently, and was astonished at how much more comfortable the seat was. Usually I have a very sore tailbone at the end of these coast-to-coast trips but this time there was no pain or stiffness. I'll have mine with me from now on. One side is covered in Vinyl and the other in textured material so you can slide into and out of your seat easily, while the seat cushion stays in place. The vinyl can easily be wiped clean and the fabric is washable These cushions are designed to boost the driver and yet also have orthopedic properties. Usually you will pay at least $49.95 for an orthopedic cushion, but ours is just $29.95
