Walmart offers the Serta Big & Tall Commercial Office Chair in Gray for $109.08. Choose in-store pickup to drop that to $104.72. That's $2 under our mention of another color from last August and the lowest price we've seen. (It's the best deal today by $43.) It features individual seat coils, gel memory foam cushions, lumbar support, bonded leather upholstery, caster wheels, and a 350-lb. weight capacity.
