I just put this thing together an think this will be perfect for watching the cnc and sipping coffee!

Yep, when you spend your whole day in the garage office you need a good chair.
I got one of those Viper chairs last year. They are expensive, but very comfortable and it is actually standing up to garage use much better than the last two I had.
If we’re talking shop chairs… I got a Aeron stool off craigslist a decade ago. They last forever and you can get parts directly from Herman Miller. This one is still original, but I have almost completely rebuilt a regular Aeron chair that I scalped from the 2000 boom. They are pricey, but VERY well built.
Nice, you are sitting up high like Captain Kirk.
All I can say is beam me up Scotty
