According to an article on Dezeen.com, the designers of Stykka call this cardboard workstation the #StayTheFuckHome Desk, in reference to a social media hashtag that has been used to promote self-isolation.
You can order one online, to be delivered to your door. Or, if you have access to cardboard and a laser cutter, you can download the template and print it out yourself, as the design is open source.
