The Back App Office is the original Back App chair, designed for sitting with the legs resting on a footplate. An upright sitting position and light movement ensure an excellent sitting experience.

The secret of the Back App chair lies in the red ball beneath it. When sitting on this chair, the feet do not touch the ground, creating a sensation similar to sitting on a balance board. The Back App strengthens the back by promoting good posture, allowing the body to remain relaxed while maintaining balance. The legs rest on the footplate, enabling free movement in all directions. Using the Back App chair exercises the deep core muscles that support the spine. The body continuously seeks balance, providing excellent exercise for the supporting muscles of the back almost effortlessly.
