How do I match drafting chair seat height to my desk or counter height?

The ergonomic rule of thumb: your elbow should be at or just slightly above the work surface when you're seated with good posture. To achieve this, subtract roughly 10"–12" from the work surface height — the result is the seat height you need. For a 36" counter, you want a seat height of about 24"–26". For a 40" counter, target 28"–30". Most drafting chairs cover a range (like 24"–33") so confirm the chair's range overlaps with your calculated target. If your surface is adjustable, set it to the height that works with the chair rather than the reverse. FindOfficeFurniture.com — call 888-719-4960 for a quick height-matching consultation.
