If you experience discomfort after long hours behind a desk, simply slapping an ergonomic mouse and keyboard on your desk won’t solve the problem. First, you have to address the root issue of sitting still for too long by standing up and walking around each hour or so. But after that, it’s worth considering your workstation ergonomics. An ergonomic keyboard can prevent the hunching, twisting and contorting that leads to discomfort. With split, tilt and angled keys, these boards help keep your shoulders and chest more open and your forearms and wrists more aligned. One ergonomic board won’t work for everyone, so I tested out 15 different models. I found my personal favorite and hope this guide will help you find the best ergonomic keyboard for you, too.
