At my workspace, I use a dual-monitor setup that (up until a few weeks ago) had been placing the laptop portion on makeshift stand to elevate the screen. It went on too long, as it looked like a cluttered mess on my desk.
After much research, I landed on the mStand by Rain Design. This stand is built to match your MacBook and function perfectly as a companion piece. The stand properly elevates the laptop, provides cord management and allows space underneath to slide a bluetooth keyboard away when not needed. It hits every point, and does so in a better-looking manner than its competitors.
Other options exist, but they'd fall into order behind Rain Design's solution.
