    The Original Adjustable Back Exercise Ball Office Chair

    When Isokinetics Inc. introduced the Adjustable Back Exercise Ball Chair for the office in 2010, it was the first of its kind to include a weight bearing, adjustable seat back like those found on quality office chairs. Regular exercise/balance ball chairs’ seat backs are designed only to provide position guidance and balance assistance, but with our seat back, you can lean back and relax, like in a regular office chair, or position it on your lower back to provide additional support, reinforcing a proper, upright sitting position. 

    Our Adjustable Back Exercise Ball Office Chair is made of reinforced, heavy duty plastic in a solid black color with a smooth finish and a black metal ball holder that looks good at home or in an office. It includes an Isokinetics Inc. brand 52cm exercise ball that we offer you in a choice of colors to fit your decor or style. And, our chairs come with 60mm/2.5" office style wheels. Similar chairs from other brands come with 50mm/2" wheels. Larger wheels (casters) provide a smoother, quieter rolling experience.

    Exercise ball chairs provide a different sitting experience than regular chairs. They encourage you to sit up straighter. Many people report that sitting on an exercise ball while at home or work promotes flexibility, coordination, motor skills, core strengthening and balance. And many people are surprised to find they simply prefer them over traditional chairs.

    It may take time before your body becomes accustom to sitting on an exercise ball. You may need to try different ball pressures until you find the level you prefer. Start by using it 10 to 15 minutes a day and gradually work your way up. If you have had back problems or injuries, make sure to consult your physician or therapist first.

    Note: We provide a small, starter pump for free for you to have a way to inflate your ball. However, exercise balls require a lot of air and it will take a lot of pumping with the free pump. So, you may want to consider purchasing at this time a high volume Exercise Ball Pump, especially if you use exercise balls a lot or have other things you often inflate, like pool toys. These pumps push air on the up and down strokes and the higher volume ones can fill an exercise ball in a matter of minutes.

    Please follow ball inflation instructions carefully. All exercise balls need time to stretch. We guarantee our exercise ball will inflate to its intended size (52cm). Please review our YouTube exercise ball inflation video for proper ball inflation.

    NOTICE: Due to recent design changes, height adapters (sold by others as an accessory to add 2" in height to similar chairs) no longer work on our brand of chairs. Please choose between our Standard frame or Tall Boy frame (which is 2" taller in sitting height). Please read product description and test sitting heights at home before you select the chair frame right for you.

    Sizing Chart


    We highly recommend you test measure estimated sitting heights at home before choosing between our Standard Frame or Tall Boy Frame

    • All measurements are based on the ball filled to 52cm. With ball on floor, it equals 52 cm or 20.5" measured straight up from the floor to a line level with ball top
    • Each person is different, but the Standard Frame user height range is about 5' 0" to 5' 11" (add 2" for Tall Boy frame)
    • In the frame, the ball top is 23.5" unsat on. Seated, a 135 lb person sits about 19.5" off the ground; 150 lb, 19"; 175 lb, 18.5" & 200 lb, 18" (add 2" for Tall Boy frame)
    • By comparison, basic solid seat chairs are 17" to 18" high
