Autonomous, creators of the affordable standing desk that was a super success on Kickstarter, are now going for a great ergonomic office chair. The features included in such type of chairs usually go for over 1000$. Early backers could get this chair for 200$ and now that the early birds specials are gone, you can still get it for 300$.
You get the usual adjustment you would be expected and hey have a patented lombar support that, after a flick of a switch, brings the back of the chair close to you to offer an unprecedented level of support.
You still have 19 days to back the project and get a chair for 50$ lower than retail. The project has already reached 10x their goal so this will see the light of day. And you can even get a special SmartDesk Art which is their standing desk but with a wood slab with natural grain.
