This chair was designed to meet your around the clock needs. Also known as multi-shift task chairs, a 24-hour office chair is designed for extended use or multiple-shift environments. This chair can be used in a 9-5 setting, but it was specifically designed to meet the needs of workers in 911 dispatch offices, nurses' stations, call centers, control room engineers, disc jockeys, and government personnel. This chair has been tested to hold a capacity of up to 300 lbs. The chair offers support to the mid-to-upper back region. The synchro tilt control allows the chair's back and seat to recline at different rates, increasing the angle between your torso and thighs. The seat depth adjustment changes the depth of the seat to accommodate the length of your thighs. Changing the seat depth keeps your back in contact with the backrest while avoiding pressure behind your knees. The waterfall front seat edge removes pressure from the lower legs and improves circulation. Chair easily swivels 360 degrees to get the maximum use of your workspace without strain. The pneumatic adjustment on this chair offers a very smooth adjustment range to achieve your desired height. The adjustable armrests take the pressure off the shoulders and the neck, which minimizes the risk of pain. The arm pads also pivot inward and outward for greater customization. The heavy duty chrome base is constructed to keep up with the demands of an intensive use chair. The beloved LeatherSoft upholstery will add an upscale appeal to your office.
