Drafting seating is similar to task chairs in their design aspects and overall functionality. The distinguishing characteristic for a drafting chair is the seat height adjustment range. Typically, drafting stools will have a much higher seat height adjustment range compared to office desk chairs. Some tall chairs will even have functions like seat depth adjustment, back tilt adjustment, and back height adjustment. This type of tall seating is usually available with or without armrests. Many are also sold with a variety of different foot stool options. Some of these foot ring styles include a tear drop foot rest, a foot ring or no foot rest option.
