What seat foam density should a quality drafting chair have?

Quality commercial drafting chair seats typically use high-density foam rated at 1.8–2.5 lbs per cubic foot. Lower-density foam (under 1.5 lbs) compresses and loses its shape quickly — sometimes within a year of regular use — leaving the user sitting on a flat, hard surface. High-density foam holds its shape longer and maintains comfortable support over years of use. Memory foam is sometimes used in premium models and conforms to the body nicely but can retain heat. When evaluating a chair, press on the seat — it should feel firm but cushioned and should return quickly to shape after you press and release it.
