Dedicated desks are allocated exclusively, and serve as your personal space within the open office. This means you are free to set up your own equipment (and cat photos) and male the space your own.
People on dedicated desk plans have access to all of the same facilities as a full-time member with the added luxury of their allocated seat each and every day they come in.
You aren’t chained to your seat, though - feel free to work from the outdoor area, or maybe park yourself in front of the TV!
