Using your new Prim Armless Drafting Chair is a breeze. First, assemble the chair following the included instructions. Once assembled, adjust the height of the chair to fit your needs by using the height - adjustment mechanism. You can easily swivel the chair 360 degrees to reach different areas of your desk. When sitting, enjoy the comfort provided by the dense foam padding and the support of the well - designed seat. For maintenance, use a soft, damp cloth to clean the vegan leather upholstery regularly. Avoid using harsh chemicals as they may damage the leather. Make sure not to exceed the weight capacity of 287 lbs to ensure the longevity of the chair. Keep the nylon casters clean to maintain smooth movement, and check the assembly periodically to ensure all parts are tightly secured.
