Laptop Risers & Stands
Raising the display so the top sits near eye level is the point, and it works. What people forget is that the built-in keyboard goes up too, which puts the wrists in a worse position than before, so a separate keyboard and mouse are part of the same purchase rather than an upgrade. Check the rated weight and the folded size if it travels. See computer stands, keyboard and mouse combos and laptop ergonomics.
