Premium anti-fatigue mat designed to improve comfort when standing for long periods. More than just a padded mat - the System 4000X has been ergonomically designed to actively encourage micro-movements for additional fatigue-relief. Its padded surface has raised massage pods and contours to provide stimulation and relieve pressure on the feet. A raised 'ergo bar' enable foot massage, ankle flex and calf stretch. The whole mat and its surface incorporates an anti-microbial ingredient, to protect the mat surface and give peace of mind for barefoot workers. We recommend using this active anti-fatigue mat with standing desks. This anti fatigue mat has an anti-slip base for added stability on all floor types. The System 4000X mat has been designed with all the features of the AFS-TEX System 5000, but with space-saving in mind. Ergonomically speaking it is highly recommended for users under 5'6" tall.
