Thanks for stopping by and taking time to discuss this! (since you appear to be new to HN, please take the abounding hypercriticality with a grain of salt) I personally think it's great that you are innovating in the field of workplace ergonomics, and, since I've been trying to improve my own posture and general health (and I think the design looks cool, too), I'm looking to back your project. I have three questions for you if you want to fully convince me of your invention: (1) How, from your scientific view, does the Freedman compare to a sitting ball or a standing desk? (2) From an engineering standpoint, the buttock pads (for lack of a better term) are going to take a lot of pressure over time. How did you keep them flexible (since they adjust flexibly to bodily asymmetries), while preventing them from wearing out? (3) Conceptually, you make the point that chairs are, quite literally, killing people (e.g. your argument above "were we meant to farm or sit?", or in the video "[what the press means by saying that sitting kills] is that in a normal sitting position, which is often slumped, you turn of an enzyme [...]. After an hour, you have 20% more bad cholesterol [...]. That leads to metabolic disorder."). How does your invention, itself a chair, though a completely rethought one, counteract this? The studies you cite (e.g. Edwardson et al., http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0034916 http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjourna... ; Zderic & Hamilton, http://jap.physiology.org/content/100/1/249.full http://jap.physiology.org/content/100/1/249.full ), show that any kind of prolonged inactivity (in humans and rats, respectively) will lead to the adverse consequences you list. What are your thoughts on this? Again, I entirely commend you for putting in the effort and expertise to develop this -- I think the result looks great, and you have my complete support. You certainly seem to have found a market eagerly searching for a solution to the lifestyle diseases of our times (which is a huge expectation, even you citations recommend a "multidimensional" approach, cf. Burton et al.). All the best!
