What size chair do I need?

Sit/Kneel Chairs are made in 5 sizes according to your leg length. Choosing the right sized Kneeling Chair will ensure better comfort.
If your height is just on the cusp between two different sizes, you should choose the size smaller if you are shorter in the legs and long in the back or, the larger if you have a relatively short back and long legs.
To find out what size Sit Kneel Chair (either with or without castors) we recommend for the length of your legs, look at the table below and see which is right for your height.

Remember, the different sizes are primarily designed to fit different leg lengths. It is not just to do with your height. There is some overlap between chair sizes - two people of similar height may have longer or shorter legs.
Designed to be comfortable and kind to your knees, the back of the seat is curved and slopes down to the rear. If you sit with your "sitting bones" where the seat curves down at the back, it will stop you from sliding forwards onto your knees so preventing pressure on the shins. By turning slightly to one side or the other, you can straighten one leg at a time in front of you to prevent constriction of the circulation. If you sit on the front of the seat with your knees at the front of the knee pad, the weight of your legs is supported across the width of the front pad of the chair, and your feet lift off the floor so you can easily move them about.
The amount of leg movement possible in this sitting position is a key feature of the Sit/Kneel Chair's design, and it depends on the seat being the correct distance from the knee pad. It is important for your comfort as you sit, and also for the benefit of your circulation that the chair does not immobilize you.
