This is a kneeling chair, or sometimes called a knee chair, designed to train you to sit in a position which keeps your back in a more neutral position. If it's used correctly, there should be a straight line between your ear, shoulder, hips and ankles. It's adjustable for height, and easy to move.
This illustrates how it is used. You can also remove one leg from the knee rest and straighten it out in front of you if you like, for changes in position. This is better for your lower back than some regular chairs. And it's a lot more comfortable than it looks. If you have lower back problems, this is something to consider.
Ray, Just send me the telephone number of the girl in the chair.
