Haha really unique product. I thought I saw it all by now but this is really new for me. Despite it looking really strange to be honest, I really think this has a huge potential to help out people with back problems sitting long times at work. This will give you the opportunity to stretch under weight (with pressure) to keep your muscles active. I also can see these chair having some kind of motivational value since you already own that chair and see it all day. Really unique project will definitely follow their Kickstarter campaign.
