Many office chairs are adjustable. You can change the chair height and move the arms, and some office chairs have adjustable lumbar support. Before tossing your current chair, make sure you're sitting optimally by trying out different positions.I cover ergonomics above. Allread, the expert I spoke with, has two main suggestions:You want your back to touch the back of the chair.You want your feet to touch the floor (or you should use a box or footrest to prop up your feet). Allread also suggests rolling up a towel to use for lower back support if your chair doesn't have lumbar support.

There are two major differences between a task chair and an executive chair, but before we talk about them, let's define the terms.Task Chair: A task chair is any office chair designed specifically for working a long day at your desk, working on a project or doing homework. They tend to be lighter than executive chairs, but are designed with ergonomics and comfort in mind. Lumbar support and adjustable arms are key factors in a good task chair.Executive Chair: An executive chair relies less on ergonomics and more on padding to keep the comfort level high. They tend to be larger than task chair

How you clean your office chair will vary depending on its materials. The chair's user manual should detail cleaning and general maintenance tips. If you tossed the paper version, check online. Many retailers provide digital versions or downloadable PDFs of their product manuals.Most chairs should be fine to clean with a damp cloth and mild soap or detergent. Test a small area first and stay away from strong chemical cleaners.
