The forearm support is an ergonomic support designed to support your forearms. The forearm support quickly attaches to the front of your desk, creating a padded desk extension that is perfect when you need extra support. Great for people who don't have armrests on their chair, the support helps keep arms and wrists in a neutral position. The padded surface... is far more comfortable than the hard, cold surface of your desk top, but with its wipeable material it is also just as hygienic.
