I've tried various things at my saw. Chairs, Stools, swivel stool, stools with bars for your feet, etc, etc. However, nothing seemed to fit me. They either made my back ache or my neck ache.
Well, I had this old chair from when I had my corner in Tony's workshop. It had just a board fastened across the arms and I found it comfy, but, my saw is now in my new workshop and the bench is slightly higher in there, so.! We improvised and Tony came up with this... It's perfect !!
I find that being able to stand + sit at the same time is so, so comfy. I have just used my saw for a good couple of hours and nothing aches. !!
Now I'll grant you it wouldn't win a prize for the best looking seat in the world but I love it..
