It's very comfortable to work on the PC with my elbows resting. I'm selling it because I hardly use it and am decluttering. It has a wide range of motion up, down, left, and right, so you can position it wherever you like. I think it's great for those who work long hours, such as telecommuters, and those with stiff shoulders. I can also sell just one, so please comment if interested. It's in generally good condition, but please understand that it is a used item and purchase it with the understanding that there may be scratches or stains.
