RockerStool is a family  of  rocking stools designed to alleviate back pain. They are designed to keep your body in motion while at your computer!  Rockerstool is the end-product of several years of research towards ergonomics, postural flow and comfort. Also, a quest to make having to sit down become just a little more fun. The design was guided by a desire to use as few elements as possible, connected by flowing lines.

What is a rockerball ? Rockerballs are stools manufactured with a rounded base, which allows the person sitting to rock in any direction, spin to instantly face any direction, or seat at any angle. Changing posture while sitting alleviates back pains. The video on the home page gives a quick idea of what it does. Imagine a rocking chair, without a back, with an endless range of motion instead of back-and-forth…

Ergonomics:  while immobility sitting in front of a computer screen is a very common cause of back and shoulder stress, the rocker stools are designed to encourage a dynamic and flowing posture at the desk. This allows your body to remain in motion, while your forearms maintain the near-static position demanded by a keyboard or mouse.

Design: the seat itself is cut out of two and a half inches (6.5 cm) of hardwood. The result is a set of deep compound curves which distribute the weight evenly on the chair so as to avoid excessive pressure points on the sitting bones. (The three-dimensional model which the seat is based on was actually established from a set of representative human prints in plaster.)  The result is a wooden seat without padding, which comfortably allows several consecutive sitting hours .

The rocker part of the chair, or ball,  rocks frontally, laterally and in any combination of the above.  This freedom of movement engages  the whole lower back in a rather complex and intriguing range of motion. It could very loosely be compared to the inflatable sitting ball, but the dynamic is much more fluid (as the base does not sag) and the balance is totally different.  It also allows spinning moves (like a regular office chair), which comes in handy to quickly face different directions. While allowing a great range of motion, the ball chair does not actually require any kind of motion, it’s design also suggests a near endless versatility in static seating position, which helps you regularly change your  posture. At rest or in motion this chair will help your posture an comfort.

Most folks prefer the ball base due to it’s greater range of motion, but these stools are also available as a “normal” frontal rocker. The normal rocker looks very similar to the ball rocker,  but does not rock sideways nor spin.  The frontal rocking stool rocks back and forth (just like a normal rocking chair -without the back)

The seat proper can also be custom ordered to a greater width.  The choice between a wide or narrow version depends on your preferences, and body shape. The wide version is quite a bit more spacious.

Sizing : the height of the chair is a function of the height of the sitter. People 174cm and shorter (5′ 8” and shorter) should take a short stem (the aluminum part). People taller than 174 cm should opt for a long stem. Any chair can be fitted with either a long or short stem.

Note: a desk fitted with a drawer style keyboard works best for folks under 165 cm (65′) to maintain proper typing posture.

Floor requirement: Rockerstools will function well on any flat floor surface. Wide and excessively cupped floorboards will interfere with the proper range of motion. Wood and linoleum floors are ideal. Carpeted surface work fine too (full-on 1960’s pink shaggy carpets have  never been tested…) Floors can be protected with a chair mat if needed, (probably a good idea on a concrete floor too.)  Standard bamboo or synthetic chair mats work fine.
