Large Chair Mats? Why are the Big Chair Mats from chair-mats.com necessary? Typical commercial grade carpet is thinner today than in the past. Available “carpet casters” enable easier movement on carpet without using a chair mat. Though it is possible to move around without chair mats, there are two reasons that make it unwise not to use chair mats.
Chair mats protect your carpet. Although newer carpet is dense enough to allow a chair to roll, carpet fibers and backing are not designed to handle the extreme pressure generated by casters. The downforce of a chair is nearly 100 times greater than a footstep! Under this stress, unprotected carpet will lose fibers and backing will break down, shortening the life of the carpet. A chair mat spreads this downforce and prevents damage to carpeting.
Chair mats reduce injury and fatigue. Use of chair mats can significantly reduce lower back and joint stain because casters move more easily across a hard surface.
In an eight hour workday, an office worker moves his or her chair more than 250 times per day. Some of these movements may be just inches, but they require up to twice as much effort without a chair mat or chair mats.
Given the frequency of these movements, a work space without chair mats is more susceptible to Repetitive Strain Injury (RSI). Chair mats are an ergonomic tool to reduce the likelihood of RSI and lower fatigue.
