A kneeling chair is ergonomically designed to keep your spine in an S position while sitting. This is the natural position for your spine. In a proper kneeling chair, a person’s weight is supported by their buttocks, as in a conventional chair, and some of the weight is placed on the shins. A person’s weight is never placed on their knees in a kneeling chair. To receive the benefits of a kneeling chair, setting it up with a proper fit is essential. A kneeling chair that does not swivel will offer the best fit for the largest variety of people. With a non-swiveling chair, make sure your workstation is placed directly in front of the chair to eliminate the need for twisting in the chair. This will keep you in the proper position created by the chair and reduce the tweaking of your back. The width of the seat needs to be wider than your hips to allow for easy movement in and out of the chair. The angle of the seat is what creates the open hip angle which aligns your back, shoulders, and neck. If the angle is too close to the 90 degree angle of a conventional chair, all benefits of the kneeling chair are lost. Usually the angle is 60 to 70 degrees from vertical. This enables the user to keep their torso in front of their hips. If the user leans back and the torso is behind the hips, you will slump. The distance between the seat and the knee pad is also important. The knees should not be bent at their maximum knee bend angle. The knee bend angle is different for everyone, depending on your joints and flexibility. At a good angle, you should be able to lift your lower shin off the knee pad while sitting in the chair. There should also be enough distance between the seat and the knee pad to allow for ease of movement in getting in and out of the chair. Once your chair is set up for your proper fit, you will start to feel the benefits. Remember, humans were not made to sit for long periods of time. Taking regular breaks from hours of sitting is just as important as sitting properly.
