Determining Proper Seat Size for the Ultima Series

To determine the proper seat pan size for the Kinesis chair perform the following measurement:

Measure length at thigh while seated __________________

Measure from back of buttocks while seated to inside of kneecap. This is called popliteal. The ideal chair would have 2-3 fingers of room between the end of the chair and the back of your leg. Without correct seat pan depth your spine is not supported and your discs are compressed. The same is true if the individual's legs are up against the back of the chair. This is typical for very petite people and cuts off circulation.
