Exercise while you sit. 

With the Back App Chair, you can ease your way into the world of active seating. A task chair equipped with a plush cushioned saddle to put you in a healthy, open-hip position, the Back App was designed to let you shift, rock, and balance as you sit. And to keep you comfy all the while.

As the Back App moves, the muscles that support your spine maintain a low level of activity, strengthening your back and improving your overall posture. A balancing ball at the bottom of the chair lets you customize the amount of movement.

Built out of strong recycled aluminum, the Back App is remarkably easy to move. If you want to go fully mobile, add the optional removable wheelbase and get rolling.

The natural need for movement

Take your fidgeting as a sign. Your body wants to rock, twist, and lean. To sway, stretch, and bounce. Active sitting keeps you more engaged and focused. Learn more.

Fabric durability

There are two major methods by which fabric durability is rated. They are called Wyzenbeek, the standard in the U.S., and Martindale, the international standard. Both methods involve rubbing the fabric against itself in a fancy fabric-rubbing machine, but they use slightly different rub patterns which results in different numbers that look similar, but the literature all says you can't convert between them.

Alcantara: a synthetic psuedo-suede material, made in Italy, that you might find in a luxury vehicle in place of real suede (it's more color-fast and durable).

- Composition: 68% Polyester / 32% Polyurethane (plus or minus 3% on each)

- Durablity: Martindale Abrasion Rating ≥ 150,000 Cycles. On the Martindale scale, a 40,000 rating qualifies for "heavy duty commercial use"
