Meet the Sprang Chair: a cool tool that encourages movement, stimulates better circulation, and improves your posture. The chair is designed for those of you who spend a lot of time sitting at work. It promotes a more active work style, strengthening your back and core muscles.
The Sprang Chair has spring coils in the back cushion to prevent slouching. It lets you direct the lumbar support where you want. You can get it in a variety of colors and finishes. More information is available on Kickstarter.
