Sizing: In two sizes, Short (17-21 inches) for shorter folks and Tall (20-27 inches), for average and tall folks. If you fall between the two sizes (20-21 inches) we suggest opting for the Tall size. This piece is used in our Ariel and Newton chairs.
How to measure: Deciding the correct height of your QOR360 chair is very important to maintain proper posture when sitting. Most chairs are too low, your knees should be lower than your hips when sitting to maintain an open hip angle and your lower lumbar curve. To find the correct height chair, stand in whatever shoes you will be wearing when sitting, and measure from the ground to the top of your patella (knee cap). This measurement is the height of your chair.
