Jim:
I hate cleaning upholstery because it is hard on my hands and wrists, and getting down on my knees is hard on my back (doesn't make sense, but trust me on this).
Taco is probably right, a good tool might help me with the hands and wrists. I am currently using a PMF internal jet tool. A smoother gliding tool would help my back some, because I wouldn't have to use on hands to secure the loose fabric and the other hand to do the cleaning, so I wouldn't be bending over and supporting all my weight with my lower back. I could use one hand to support myself. Make sense?
Also, I need a good folding table, with an adjustable height (for us tall guys), that I can use to allow me to stand the heck up while I am cleaning cushions. (Also to relieve stress on my back.) It has to fold up into a very small, flat footprint for storage into an already cramped van.
I am very slow with upholstery. I get my price for doing it, so I don't mind being slow from a pricing standpoint, but being slow cleaning something that is also placing my body in stress is a killer.
