Many thanks for the comments. Apologies, for another delayed response. We're approaching $500K for our Kicstarter with 40(ish) hrs to go. WE'll end up top 20 in design, to date.

Here are some responses. Mmm, I guess there something that makes you guys, err, just a touch critical. I think we need to organise a testing group of you guys for the Quadruple-blinded Randomised Controlled Trial, that I am working on for my PhD at Huddersfield University in the Spinal Research unit there, we estimate 3yrs to do a good job, (before anyones scepto-meter goes off I'm sure most of you know what quadruple blinded is aiming at but please google if not). Sometimes they let osteopaths to University in even if they are a bit alternative. Maybe I should call myself a doctor like chiropractors do, as that will give me a lot more credibility. You really think so???

Ok, bit cross there, apologies.

Mithaldu, Jeez! Marketing fluff, clumsy..woah.

You'll find my website if you google and I give a smattering of papers there to get people started. Doing a Phd means that you have to know more about your subject than anyone else in the world. You are creating new knowledge and it is the most awesome feeling. There's a picture of a cucetani chair in the beginning of my animation. I thought mine was from 7.5k ago, but will check. I'd imagine there were others before that but that's the earliest I know of.

Mezzopiano, Thanks for the great questions.

sitting balls- 1. No height adjustment 2. Good for core work out, but all day long? 3. People look a bit of a plonker sitting on one...

We can make polymers last for a long, long time now, too long in most cases. How long do you think the fabric ones last?

I've been assiduously avoiding 'selling' The FreedMan Chair. I've just tried to tell the story in the best way I can and asked people make up their minds. I'm saying the world is round guys. If you can't see that you're living on a flat one...

I really hope you come along for the ride and give it a go.

Cheers,

Simon
