Does carpet affect the stability of a sit-stand desk?

Thick carpet (over 1/2" pile height) can cause a sit-stand desk to rock or list slightly because the rubber glides sink unevenly into the pile. Use a hard-surface chair mat (36"×48" minimum) under the desk's footprint to give the glides a firm, level surface on carpet. On low-pile commercial carpet (under 1/4"), most commercial sit-stand desks with good leveling glides are stable without a mat. FindOfficeFurniture.com carries sit-stand desks engineered for stable operation across floor types — call 888-719-4960 for the best deals.
