Using your Gianna Task Chair is a breeze. First, assemble the chair following the simple instructions provided. Once assembled, adjust the seat height using the pneumatic lever under the seat to your comfortable level. You can also adjust the tilt tension with the locking tilt control to suit your sitting style. When moving around on carpet, the dual - wheel casters will roll smoothly. Remember, this chair is for indoor residential use only, so don't use it outdoors. To keep your chair in good condition, regularly wipe the mesh back and foam seat with a soft, damp cloth. Avoid using harsh chemicals as they may damage the materials. Also, make sure not to exceed the 200 - pound weight capacity to prevent any structural damage.
