Standing desks are definitely catching on. Found this new one via Kate Kendall. The Ninja Standing Desk started out as a Kickstarter project which was successfully funded. The desk works by attaching to a door, and comes with 2 or 3 shelf configurations for you to sit or stand. The main advantage is the portability – it folds up into a compact package that you can bring along when traveling or working remotely.
It’s not as affordable as the aforementioned WorkEZ desk, but still within the reach of most at USD177 onwards depending on configuration and shipping. Strangely though, they are only accepting payment via Bitcoin, which reduces the accessibility of the product. Hopefully they will incorporate more traditional billing methods soon.
