Laptop Shelf System
Overview
Over ten years ago I used an old stacking shelf to keep my computer off my lap, and it's been a staple for my posture and wellbeing ever since. A $20 solar Logitech keyboard and a vertical mouse later, it helps me stand up and sit upright wherever I go. The best laptop accessories I have ever bought, hands down. Try them with the links below, and check dimensions.
Happy working!
