I needed a standing desk workspace that could fit into a suitcase. I wrote this post to save people the trouble of having to find it themselves: http://bit.ly/travelworkspace
In this video I show the Rocelo laptop risers:
These little laptop risers weigh 7 lbs each and rise to a height of 15". I use one for my monitor, and one for my keyboard and mouse. By having two separate risers, I have the benefit of:
1. The ability to control my distance from eyes distance from my screen
2. The computer monitor does not shake because I am typing on a separate surface.
Though they are not super light, these laptop risers are extremely portable in size are very very tough. My monitor + mount is about 10 lbs, and it's 0 issue getting the monitor stand to rise.
