The saddle posture, with legs spread apart and supported by the feet and buttocks only, supports good natural back posture and allows better blood flow than sitting with the thighs.
The BetterPosture chair uses a standard 5-point caster wheel base, which is considerably wider than the seat and interferes with the feet when attempting to roll the chair while sitting.
Because the saddle position exploits anatomy for natural support, it demands a certain amount of muscle tone. This develops naturally over a week or so, but can cause some discomfort in the meantime.

To avoid back pain after a prolonged day, you can adjust the tilt of the chair to provide better support. You can also configure how far the back of the chair is rocking as you push down on it with your weight.
The bungees provide just the right amount of support for legs and back without cutting off circulation. The design of the chair naturally complements the contour of any body.
This chair puts long term comfort first. The mesh material is very breathable and provides a bouncy cushion. The back part of the chair has adjustable resistance for leaning back. If this chair is set up the right way, it can feel just like a recliner.
The height, angle, and recline resistance for the back of the chair can all be changed. The back of the chair can be locked in place, or set to move freely. The arm rests move forward and backwards as well as up and down. The seat area slides back and forth. And of course, the height of the chair moves up and down.
The tilt angle of the chair is fully customizable. Unlike most others, you can even configure the back of this chair to tilt forwards for maximum comfort. It offers good support for your back in any position.
