Support your lower back
If you don’t have an ergonomic chair, using some cushions may help adjust your sitting position to support your lower back throughout the day.
Lift your laptop
Adjust the top of your screen to around eye level so you can relieve stress on your neck and aren’t hunched up all day. You could use a laptop stand, an external monitor if you have one, or even a pile of books.
Get the right mouse and keyboard
On average, if you use the computer more than 6 hours per day, an ergonomic mouse and keyboard help you work in a more natural posture throughout the day and reduce muscle strain.
