How It Works The Evolution Chair™ is a high quality burst-resistant ball contained within a moving base. Simply by sitting on the ball and adjusting your body to the bounce, sway and tilt of the ball, deep core muscles are engaged. These constant small adjustments build the endurance and strength of the postural muscles which facilitate optimal posture. Active sitting is guaranteed to complement your regular exercise program.   Some Internet Explorer v6 users may experience some technical issues while trying to purchase this item using our “Buy Now” button.

  Evolution Chair brochure

People spend hours every day sitting on chairs; however, the human skeletal frame is not designed for chairs. Even ergonomic chairs, intended to hold the body upright, only do so effectively for a short period of time. After that, the postural muscles tire and the body slumps and slouches as the spine twists out of alignment. Ultimately, postural muscles weaken, leading to back pain and potentially putting you at risk for a back injury.

By introducing a dynamic element to the sitting experience, the Evolution Chair™ keeps your muscles active while you are seated. This not only holds you in the correct position for your spine but also allows you to build your core strength while you sit. This new concept in sitting can contribute a great deal to your overall well-being, especially for those who sit for long periods at a time.

How to use the Evolution Chair™
Before sitting on the chair for the first time, you will need to follow these instructions in order to properly use it:

Day 1 Prep
• Pump the ball (air compressor is recommended ) until it reaches a height of 21” from the floor to the top of the ball
• Let it sit for 24 hours to allow for expansion

Day 2 Prep
• Let air out as needed until comfort level is reached. Balls are going to vary from 50cm – 60cm
• Place the wheels straight into the base, or use height inserts as needed
• Knees should be at a 90 degree angle with hips slightly higher than knees. Initially, this is not a full day sitting chair as time is needed to allow muscles to build up and work their way into sitting on it all day. From previous poor posture, muscles will fatigue as the body is being ‘forced’ into a proper position. ‘Active’ sitting helps build the core muscle groups

Breaking into Active Sitting
Your body will need time to get accustomed to sitting on the ball. Please follow our suggested usage instructions for an incremental approach starting with short periods for your first week and progress to longer sitting periods. This is what we suggest:
