Desk chairs

I bought a desk chair at a friends garage sale and it's nice and big and comfortable. The only think it has a low back so when I doze off at the computer I wake up with a sore neck. My buddy works for a company that sells office furniture and a customer traded in 2 nice chairs and his boss told him he could have them if he had a use for them. Thinling of me with my low back chair he grabbed them. He's bringing them over in a few minutes so I have to get going.
