New Oculus Quest feature lets you mark your actual couch in VR - The Verge
A new Oculus Quest feature expands the headset’s Guardian mode by letting you mark your real couch as an object that’ll show up in VR.The Guardian is an Oculus safety feature that lets you draw lines around your environment that act as a virtual boundary and appear in VR when you get too close to the edges; this couch mode is the first time that the Guardian has worked as more than just a simple measure of floor space.
UploadVR reports that you can mark out your couch or chair by touching one side and dragging out a virtual blue rectangle across it to define the correct size.
