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 item with the TEMPUR® Lumbar 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.
