For comfort and to decrease the risk of strain injury, it is important to pick a good chair and to set the sewing machine at a good height for your own body. Susan Delaney Mech, M.D answered this question as follows:
- The first step is to set the height of your sewing chair. The seat should be at a height that allows your feet to rest flat on the floor and your knees to make a perfect 90-degree angle. A secretarial chair makes a good, adjustable sewing chair.
- The next step is to lower your sewing machine table until, with your elbows bent at a perfect 90-degree angle, your fingertips can rest on the feed dog of your machine. I am 5 feet 6 inches tall, and my sewing machine table is 22 inches off of the floor.
- Proper chair and sewing machine height, combined with good posture of your back and neck, and hourly breaks, will go a long way toward preventing (or healing from) Repetitive Strain Injury.
