Sissel introduced the Sitfit in 1994, it was the very first air filled disc used to help promote a correct sitting posture. The Sitfit has proved to be a valuable tool in the reeducation of the "core" muscles and rehabilitation of the back. It is durable enough to be used as a wobble board to increase proprioception and ankle stability.
The Sitfit has found it's way into several diverse and separate disciplines were it is used to treat a wide range of conditions and situations. They are used from amputee rehabilitation clinics, in dyspraxia, ADHD and MS conditions to exercise/fitness classes and Pilates.
Sissel now produce the Sitfit Plus, the only dual purpose air filled cushion, with it's "squared" off edge giving more thigh support for longer periods of sitting. Turn the Sitfit Plus round and you have a round edge for more dynamic sitting or exercise.
