The Språng Chair
The Språng Chair was officially launched on Kickstarter in the summer of 2016, and the patents have just been awarded by the USPTO.
The Språng Chair takes a novel approach to sitting, encouraging the sitter to remain active and not sedentary.
Currently we have shipped close to 250 chairs both in the US and internationally. I recently heard from a retired marine who healed his back by using the Språng Chair.
