Built with a number of comfort features, the Matrex Leather Chair with Headrest is hard to beat. The top grain leather seat and headrest are both multi-adjustable. A pneumatic seat height adjuster is mounted on a metal base - most office chairs are predominantly plastic. Even the padded arms can be adjusted to your specifications. The seat and back are linked together by a unique 2-to-1 synchro tilt that moves the back at twice the angle of the seat. The tilt tension can be adjusted or locked for individual user weights and strengths. This way you can lean back significantly with a seat relatively parallel to the floor but angled enough to keep you from sliding off during late afternoon, secret siestas.
