As you sit down, by distributing your weight more evenly over the surface, the TEMPUR Seat Cushion improves comfort and reduces the sensation of numbness. It has been engineered for use on any chair. If you work at a desk, why not twin this with the TEMPUR Lumber Support for enhanced pressure relief. The soft blue fabric part of the cover also meets Oeko-Tex® 100 standard. This means it has been tested for harmful substances and poses no risk to health.
