Reprogram Your Back, Exercise While You Sit.

Don't tell her we said this, but your mom was wrong. You don't have to sit still. In fact, you shouldn't.

The experts all agree: moving is good. Movement is healthy, and with the Back App 2.0 Chair, you can ease your way into the world of active seating.

This is the missing link between Task Chair and Saddle Seat. Equipped with a plush, cushioned chair and a saddle shape to put you in a healthy, open-hip position, the Back App was made to let you shift, rock, and balance yourself as you sit, and keep you comfy while you do it.

A balancing ball at the bottom of the chair will let you customize how much you want the chair to move, and 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. 'Cause your mom was right about this one; you should sit up straight.

Built out of strong-but-lightweight (also recycled!) aluminum, the Back App is remarkably light and easy to move, so it can migrate all around your home or office. Or, if you want to go fully mobile, add the optional, removable wheelbase and get rolling.

Upholstery Options

Nordic Wool

  • Basic Description: a hardy, antistatic wool blend, naturally flame- and dirt-resistant.
  • Composition: 88% Wool, 12% Polyamide
  • Durability: Martindale Abrasion Resistance - 120,000 rubs. What on earth does that mean? It translates roughly to rubbing your jeans back and forth on it 120,000 times, or ten times a day for about 32 years, before the fabric bails.
  • Care and cleaning: recommended "gentle vacuuming, preferably every week, with a soft nozzle." If you need to remove spots, try lukewarm water with or without a neutral detergent.


  • Basic Description: 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)
  • Durability:
    • Martindale Abraision Rating ≥ 20,000 Cycles
    • Martindale Abrasion Endpoint ≥ 150,000 Cycles
      What the heck does any of that mean? Basically, you can sit on it and stand up again (or squirm around really hard), 150,000 times (or 10 times every day for 41 years) before the fabric gives up.
