Ever since I screwed up stripping my old pair of shield back desk chairs, I've been using various chairs from around the house at my desk. Most recently I've used some mission-ish style chairs that we had from our old table. I'm not overly excited about them, but they were free. I wanted red chairs with a pretty fabric, but these chairs had a wooden seat. My sister suggested putting foam on the wooden seat and making my own seat cushion. And voila! Red chairs with pretty fabric seat. I already had the chairs and the fabric and even one can of red spray paint (Krylon's Cherry in high gloss), so the total cost of this makeover was $3.50 for another can of spray paint.
I like that my little buddies can come and sit with me again while I'm at my desk:
