Ah right!

Cool

I want to design my own type because I've seen how usefull the technology is.
I will use swivel bars so that more travel happens so when you rise up out the seat the seat follows you up and your back will always be supported so you want injure it.
I might try make this but it will have to be from wood because I don't know how to work with metal! lol!

What do you think?
