Enter the Anthrodesk's sliding standing desk converter. It's a cost competitive $99 CDN solution that doesn't take up too much space on the desk. Anthrodesk was kind enough to give us a unit so we could see if it was something we would recommend. We had multiple users at Granville Physio take it apart and set it back up and the comments were consistently that it is easy to assemble (it requires no tools). Additionally, it is light enough to easily pick up which is a benefit in places like a dorm room where if you need desk space you can lift up the desk converter and place it on your bed.
Most importantly we need to talk about how it functions. Once set up, we found that while the hinges for height adjustments are easy to access and use, it takes effort to move the platform upwards and requires removal of your device from the platform before adjusting. While the desk converter provides ample adjustment for the keyboard level height, the monitor level height is more constrained.
As you can see in the photos below for the first individual at 5'2" there is about 4 more inches of height adjustment available for optimal monitor height off of a tablet. She is able to have the desk converter at a good height for both her elbows and neck. In the second picture you can see this 5'11" individual has the keyboard tray in a good position but the tablet height is still several inches below the ideal height.
