Sitting at a raised work surface only works if your feet have somewhere to go. This drafting chair puts the seat between 22.5 inches and 30.5 inches off the ground, well above a normal desk chair, and adds a foot ring that lifts and lowers independently so the ring can be parked at whatever height your legs actually rest at rather than a fixed one the factory chose. Get that pairing right and the weight moves off the back of the thighs, which is where most tall-chair discomfort comes from. Behind you, an adjustable lumbar support slides to meet the curve of your own spine, and the 19.5-inch by 21-inch ergonomic backrest is shaped to fit that curve rather than press against it, so fatigue builds more slowly through a long stint. The backrest and seat are made from breathable mesh fabric, which is what makes the chair usable in all seasons and especially in a particularly hot one, while a high-density sponge cushion underneath means you can stay seated for hours without the padding bottoming out. The armrests flip up and down, so you can raise them out of the way when a task calls for free elbows or drop them back when you want somewhere to rest. A five-claw base spreads pressure across a 27-inch by 27-inch footprint for exceptional stability, and wear-resistant, smooth-rolling casters give free mobility across the floor. The 360-degree swivel seat changes direction effortlessly so you can turn to chat with others. Overall height runs 42.5 inches to 50.5 inches, the chair itself weighs 27 lbs, and the frame carries a rated load of 300 lbs on every setting.
