These 2" height adapters are made for the Stel'Air Backless Stability Ball Chair
Ball chair leg extenders are used by taller persons (6' and over) to ensure comfort and proper posture on the backless ball chair. While seated on the ball the legs should not be parallel (90° angle) to the floor but at a more open angle to reduce stress on the spine and hip flexors. Raising the height of the ball chair will do this.
There are no tools required to install the height adaptors.
Ideal for persons 6' tall or more.
Improving posture and stress to spine and hip flexors.
Leg extending ball chair height adaptors will immediately add 2" height to the ball chair
