I have a simple lovely IKEA desk and £100 IKEA chair. Never loved it, it’s heavy, I fidget because it spins, and I hate the spider legs. Because we are decorating (long story), I am sat on a basic IKEA stool today and find it really comfy. Maybe cushion seat would be nice, but OK without back support. And I can rest my feet on the floor as spider legs do not get in the way. I will test drive the stool this week. Just wondered what others find comfortable for desk work at home?
