If you're not able to position your elbows in line with the desk, adjustable armrests can come in handy. To really make your working from home space a place of comfort, make sure your armrests are positioned correctly. They should sit just below your elbow when your hands are resting in your lap (a lot lower than most would think). For the best and most comfy setup, you may switch between using the armrest to, well, rest your arms on and going without during your day.
