Designed by a leading expert of the Alexander Technique, which is based on a practice of body alignment and musculature balance, the patented Jobri Sit-A-Round Ball Chair is ideal for dynamic seating. A Ball Chair enables you to literally float out of your bad postural habits that result in or aggravate that nagging chronic back pain. Use of the Ball Chair promotes spinal alignment while strengthening the muscles in your back and torso.

The Sit-A-Round Ball Chair supports the weight of your pelvis and facilitates the proper use of the 'sit bones,' encouraging an even distribution of weight. The inflated ball chair sends a continual subtle message to "move up" which keeps your spine from slumping in a "C" curve. The ball chair responds individually to your weight and body movement. Tension is released throughout your shoulders and back. This is an ideal chair for people whose work involves long periods of sitting as well as for those who have injured their backs.

This Jobri ergonomic office ball chair can be used at the office or home. Locking casters make stability easy. The ball chair inflates easily and accommodate users up to 500 pounds. The height of the seat pneumatically adjusts from 26 inches to 29 inches and the seat width is 16 inches. The office ball chair has an anti-burst design and you will receive a free pump and instructions with your order. The Sit-A-Round ball chair has a five year warranty on all moving parts and a two year warranty on the fabric.
