Many office chairs feature omnidirectional caster wheels for improved mobility, but these wheels are designed primarily for bare floors or low-pile carpeting. Thick, padded carpeting or shag carpeting can bog down the wheels, impeding mobility.If you work on thick carpeting, consider a glider chair with smooth metal feet for added mobility. You may not be able to push away from your desk and coast to the copy machine with a glider, but a glider won’t dig into your plush or padded carpeting, either.
