1. Slide your seat until your knees are slightly bent when you're pressing the gas. Move your seat forward if your legs are completely extended when you press the gas pedal. Move your seat back if your legs are bent too much. Keeping your knees slightly bent while you drive will prevent knee pain.
2. Sit so there's a gap 2 fingers wide between the back of your knee and the seat. Place 2 fingers between the edge of your seat and the back of your knee. If you can't fit both fingers in the gap, slide your seat back until you're able to.
3. Raise your seat up until your hips are level with your knees. Raise the seat higher if you can’t see clearly out the windshield or windows. Don’t drive with your hips lower than your knees.
If your car doesn’t have a control to adjust the seat height, sit on a cushion to help keep your hips level with your knees. Make sure you’re not elevated too much or you’ll have to bend down to look out the windshield or windows.
4. Adjust the backrest so it’s reclined at about a 100 degree angle. Sitting reclined at this angle will decrease pressure on your lower back so you’re more comfortable.If your shoulders lift from the backrest when you turn the steering wheel, your seat is reclined too much. Move the backrest up more if you are hunched forward when driving. When the backrest is in the proper position, you should easily be able to reach the wheel, and your elbows should be slightly bent.
5. Move the headrest so the back of your head is centered in the middle. If your head is above the headrest when you’re sitting in your seat, move the headrest up. If the back of your head is exposed below the headrest, move the headrest down. Ideally, the top of your head should be level with the top of the headrest.
6. Adjust the lumbar support so it fits in the curve of your lower back. The lumbar support is the raised portion of the lower backrest. First, adjust the height of the lumbar support so the bottom edge is level with your waistline. Then adjust the depth of the support so it completely fills in the curve of your lower back.
If your seat doesn’t have lumbar support, roll up a towel and put it in the curve of your back while you’re driving.You can also buy an attachable foam support to use in place of lumbar support if your seat doesn’t have it.
