As a lampworker (beadmaker) I spend a lot of time sitting, which isn't all that great for my already compromised back. When I set up my work station I had one of my physio people come in and look at how I had things set up. He raised my chair and mentioned I needed something to rest my elbows on. I had a piece of black foam for a long time but it finally compressed down and was almost useless. I had seen bean bag style elbow pads but often they were fabric, which would of course get holes fast with hot glass bits flying about. I cannot unfortunately remember where I found these leather ones but I love them. They are easy to clean and don't burn through if a hot piece of glass happens to land on them.
