Many of us sit too long. I know I do. From the moment I slip behind the desk in the morning, until well into the evening when I put my Mac to sleep, my posterior is parked in a chair. But there are plenty of studies citing this hour-after-hour sedentary lifestyle, even in an ergonomic task chair, isn't doing our health any favors. So I've been researching a few "active sitting" options, in the hopes of upgrading to something more core-engaging...
Buoy: For a few years, exercise ball chair gained traction as an alternative to traditional office chairs, the spherical shape engaging the body's subconscious system to keep the spine upright. Although the free rolling design is indeed more abdominally engaging than a regular task chair, the design itself wasn't necessarily best suited for a work environment, nor necessarily space efficient. The Buoy takes the same idea and refines the shape to a more streamlined and compact form factor, a weeble-wobble stool which "swivels, turns, tilts, and moves up and down". $239.00
ergoErgo Seat: if budget is an issue and you're looking to give active sitting a try, the giant plastic spring-shaped ergoErgo Seat is likely your best bet. Designed for users from 5' to 6'4" tall, the vibrantly colored work stool works both in and out of a work environment as a flexible muscle engaging partner whether at a desk or pulled aside for workout duty, as shown in the video up above. $99.00
Core Chair: this is the task seating I'm most interested in possibly switching over to due to a few notable features incorporated into the design which makes the transition to a non-traditional seat a little more realistic for someone who has used a supportive task chair for years now: 1. the Core Chair retains a small lumbar support, 2) the design is very compact in design and easily rolled under the desk, out of sight, 3) the swivel action appears dynamic, but still within a realm of controlled motion (I don't want to end up on the floor while leaning back or forward throughout the day). I look forward to the day when I can hit the "Enter" key while in a handstand position. The Core Chair costs $995.
