who else does upholstery

I do upholstery but it has been a while since I have. I used to have a mattress manufacturing company and I had a bunch of specialty equipment that I collected along the way. One of my favorite tools is the pneumatic hog ring gun. I still have 5 or 6 and do they make attaching seat covers easier.
That sounds and looks dangerous. At least a nail gun you could pull it out if it doesn't go clean through. an expert only tool
