I’d just get a chair that’s comfortable without any add-ons. I have a Steelcase Leap V2 at home, and a Steelcase Amia at work. I can and have sat in these for 16hrs plus in a day. Tempurpedic also has nice, thick butt cushions in their chairs at a fraction of the price.
A fellow Steelcase fan. Awesome. What’s yours?
