The Evolution Chair


The Evolution Chair™ is suitable for anyone who sits for extended periods of time. Good posture and core strength are the best insurance against back injury.

The Evolution Chair™ is a unique and comfortable alternative to an ordinary chair. Sitting on the Evolution Chair™ takes pressure off the spine, releases muscle tension, corrects posture, improves balance and strengthens the torso.

It is suitable for all ages. Anyone who sits at a desk for hours; students, office workers, computer professionals, health care professionals, individuals with back and neck problems and even children who need to be encouraged to assume a more correct posture. In fact more and more dentists are using the Evolution Chair™ to alleviate chronic lower back pain which bears testimony to the therapeutic benefit of the Evolution Chair™.

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.

The Evolution Chair’s stability ball is made of a very high quality anti-burst material that is available in one standardized size only. This ball will adjust in size from 50cm to 55cm (similar to a balloon) dependent upon level of inflation. The variation in ball size allows people of different heights and weights to inflate/deflate the ball in order to attain their ideal ergonomic position and comfort level.

The Evolution Chair is height adjustable. Height adjustability is essential to the design of a proper ergonomic chair. Height inserts are provided with the Evolution Chair to raise the height of the base to accommodate an individual’s leg length.

The Evolution Chair is specifically designed without a backrest to provide optimum health benefits. The absence of a backrest allows for full activation of your deep core muscles. When you sit on an Evolution Chair, your body balances and adjusts to the bounce, sway, and tilt of the ball, which engages your core and builds the endurance and strength of your postural muscles. The presence of a backrest impedes this process, compromising the health benefits of active sitting.

You can use the high-quality ball on its own to perform stretching and strengthening exercises, in addition to using it as the seat for the Evolution Chair.

The weight limit of the Evolution ball is 300 pounds (136 Kg).

The Evolution Chair has a compact design that fits nicely in tight areas and tucks neatly under your desk.

Base width 20” x 20” ( 51cm x 51cm)
Base height adjustable from 8 ½” to 10 ½” (22cm – 27cm)
Ball height adjustable 20” to 23” (51cm – 59cm)
Measure the ball perpendicular to the floor .

Chair is shipped deflated to reduce space and costs. Comes with inflation pump. Can be shipped directly to patient, if preferred.


The Science

Stability ball chairs are not just another trendy fad. The health benefits of sitting on exercise balls are backed by solid science.

Numerous independent studies have been conducted by medical doctors, chiropractors, occupational therapists and ergonomists supporting these claims.

Research has shown that “active sitting” significantly reduces spinal compression which over time can lead to disc degeneration. The dynamic movement of sitting on an unstable ball also normalizes spinal fluid diffusion and provides proper nourishment to the cartilage cells that help to keep the discs elastic and strong.

The Evolution Chair’s ergonomic design successfully passed rigorous testing by the Canadian Physiotherapy Association to achieve product recognition status and we are actively endorsed and promoted by a wide range of medical professionals. The all-inclusive Evolution Chair Kit includes risers to adjust the base height (essential for proper ergonomic positioning), the smooth rolling base provides safety, stability, and effortless maneuverability, and the back-less design triggers core engagement which is necessary for health and postural benefits.  The Evolution Chair’s versatile design has become immensely popular in multiple   environments including schools, home offices, dental offices, aesthetic centers, call centers, and air traffic control centers.

Active sitting also leads to increased brain stimulation, alertness and learning ability. Studies done in classrooms revealed marked improvement in students’ ability to focus, take notes, and engage in class discussions while sitting on stability ball chairs.


The Science of Ergonomics

Height adjustment illustrationOur company focuses on fulfilling the ergonomic goals of health, safety and productivity. Proper ergonomic design is necessary to prevent repetitive strain injuries and other musculoskeletal disorders, which can develop over time and can lead to long-term disability.

Posture Perfect Solutions Ltd. knows the importance of providing a "fit" between the user, equipment and their environments and therefore we designed a height adjustable ball chair. Height adjustability is vital for proper posture because your knees need to be lower than your hips while sitting. Risers are included with the Evolution Chair to raise the height of the base to accommodate anyone between 5’ – 6’5”. The ball can also be inflated from 50 cm – 60 cm for your ideal ergonomic position and comfort level.






Inflation Instructions

  1. 1
    Remove the Evolution Chair base and ball from box and check for shipping damage. (It is normal for balls to have slight creases or fold marks when first inflated.) Allow ball to reach room temperature before inflating.
  2. 2
    Screw inflator tip into tip of pump. Insert inflator tip into hole in ball. Alternatively, the ball can be inflated at a facility that has an air compressor such as a gas station, bicycle store, dental office, etc. Inflate ball to the recommended height and firmness. (See below.)
  3. 3
    After correct inflation is achieved, insert plug into hole until head is flush with the surface of the ball. Slight leakage may occur over time. Re-inflate as necessary.
  4. 4
    The Evolution stability ball is made of a very durable anti-burst material that varies in size by adjusting the level of inflation. This allows people of different heights and weights, to attain their ideal ergonomic seated position and personal comfort level.


Large and small ballYou will want to fill the ball to a level that provides you with a comfortable yet supportive cushion. The amount of inflation will depend on your height and body weight. Ideally, if you are sitting on the Evolution Chair with your feet flat on the floor, your hips and knees should form an angle slightly greater than 90 degrees with your hips slightly higher than knees.

To inflate with the provided pump we recommend filling the stability ball approximately 80% on the first day. Let it sit for 24 hours to stretch before filling to 100% or so that you can dent the ball about two inches (5cm) if you stick your finger in the ball.

If your are 5 feet tall, you would not inflate the ball as much as someone who is 5 feet 11 inches. Likewise, a 250 lb individual would inflate the ball more than a 150 lb individual of equal height. Regardless of your height or weight combination, you should not exceed the maximum diameter of the ball. If your ball is underinflated, the ball will not be as firm, but you will still benefit from the Evolution Chair.



Our Recommendation



We recommend using an air compressor for the initial inflation. See below for inflation using provided hand pump.

Inflate the ball until it is firm and measures from 20" — 21" high (52cm — 54cm) when measured perpendicular from the floor to the top of the ball on the first day. Let the ball sit and rest for 24 hours to allow the material time to stretch and relax, the following day gradually release air until your personal desired firmness level and correct ergonomic height is achieved.

Have fun!
