Leap® Black Leather Work Chair with Aluminum Base

Ergonomics

The Leap chair was developed based on the finding of four years of research, 27 scientists, 11 studies and 732 test participants. Out of this research came important discoveries about how people sit, leading to advanced seating technology.

The Leap chair's back moves as your back moves. Its arms move as your arms move. Its seat moves as your seat moves. It's the first chair that actually changes shape to mimic and support the movement of your spine.

Ergonomic features of the Leap chair include:

a. LiveBack®

The Leap chair's back changes shape to support the entire spine. This can reduce the chance of lower back sag and a hunched posture, which may weaken disc walls, stress back ligaments and cause deterioration of the spine.

b. Thermal Comfort

Thanks to slats in both its back and seat, and the special foam it uses, the Leap chair offers excellent "breathability". It effectively controls a balance of heat and moisture so you stay comfortable.

c. Adjustable Seat Depth

People don't fit neatly into average body sizes. Leg and torso lengths can vary independent of a person's overall height. Adjustable seat depth accommodates different body shapes for long-term comfort.

d. Lower Back Firmness

Lower back firmness control enables you to set a constant amount of firmness to help maintain your lower spine's natural curve.

e. Height, Depth, Width, and Pivot Arms

Arms telescope in and out, move forward and back, pivot and adjust up and down so you can find a natural position that comfortably supports the wrists, forearms, shoulders and neck.

f. Natural Glide System™

As you recline, the seat glides forward so you can recline without leaving your Vision and Reach Zone, so you stay oriented to your work. This encourages more varied postures so there's less static load on the spine.

g. Flexible Seat Edge

When you recline or lean forward, the seat edge flexes to relieve pressure on the back of the legs.

h. Upper Back Force

Upper back force control enables you to set the amount of "push back" that you desire as you recline, regardless of body size. So you'll receive just the right amount of recline support.
