Info: Active Sitting Stool, in 2 Styles: Hemisphere, in 3 Heights; & Perch, w/ Foot Rest Ring

Perhaps you've heard about the many potential benefits of active seating and have contemplated getting a stability or balance ball chair to use at work, but worry it wouldn't really fit in with that environment, or are deterred by the prospect it'll be a bit "too much" and thus wouldn't get much use. If so, the Hemisphere Active Sitting Stools from Evolution may present an ideal compromise.

Product Notes:

The Evolution Hemisphere Ball Stools still provide many of the same benefits as The Original Evolution Ball Chair such as improving your core strength, circulation, and posture to help reduce back pain and sitting fatigue. But they do so on a far more conventional-looking base and only use about one third of a yoga ball on top (the Northern Hemisphere, as it were), which virtually anyone could sit on without difficulty or reservation, just as they could on a piano stool topped with a pillow.

In essence, they mount what has been variously called a Balance, Sit, or Sitting Disc; or a Stability or Wobble Cushion; or a BOSU Balance Trainer (which all require you to make a series of micro-movements to maintain your balance as you sit on them), onto a contemporary base much like the ones found on other task chairs and stools found in offices, featuring a fully swiveling base and hydraulic lifts.

Hemisphere rolling caster and stationary glide

They come here in four varieties:
* the three Hemispheres, which all come on a conventional five-pronged base, and are of varying heights, which are oriented to different user and desk sizes; and,
* the Perch, which is a tall stool about the same height as a Bar Stool or a Drafting Stool, which adds a foot ring. This design can be the perfect pairing for working at a standing desk, a drafting table or artist's easel, a workbench, or even for many retail, food or beverage service jobs behind a high counter.

Please note: two of these models - the Standard and High Hemispheres - are equipped with a set of four rolling casters (two of which lock); while the others get mounted on non-rolling stationary glides, as shown. Naturally, they all come with a pump to inflate the seat.

Either way, between their absence of a back and the instability introduced by the air-filled half-ball, all of these stools counteract the natural tendency to slouch while sitting passively, and get you to not only engage the muscles in your core and lower back, but also to move your ligaments and discs, which can help rehydrate the discs in your lower back, pump more cerebral spinal fluid, strengthen your spine, and improve your posture, among other things.
