Whilst monitor risers are designed for your desktop monitor, offering not only ergonomics and comfort, but also storage underneath to accommodate your keyboard, gaming console and stationery, you can also use one with your laptop.
Raising the laptop screen to eye level has its obvious advantages although this also means your laptop keyboard is higher, so you may need to adjust your sitting height to avoid lifting your shoulder for long periods of time. Alternatively, pairing your laptop with an external keyboard and mouse while using the riser may be more comfortable.
