I made a denver chair a couple of years back and while it worked fine in time I found it a pita to keep moving around and get level every time I moved the scope, its now loseing itself under some wandering jew down the back. .
The step jjj mentions would likely work as well and be a little kinder and quicker to move around , I mostly use a lightweight chair from an outdoor setting these days ,leaning into the handles when standing ,one knee on the woven seat when looking a little lower in the sky and sitting for charts and a little quiet time .. hasn't bucked me off once yet .
