This is the seating side of a lunchroom, cafeteria or breakroom. Tables sized and shaped for people eating in shifts, plus booth models where you want a defined seat instead of an open bench run.
Rectangular and oval tops line up in rows and move a lot of people through a fixed footprint. Round, square, octagon and hexagon tops break the same room into smaller groups, which is why several of these lines get specified for classrooms and training rooms as often as cafeterias. S-shaped tops sit somewhere in between.
Folding and fold-and-roll models are here for rooms that do more than one job. They fold, roll off the floor, and give the space back for an all-hands, a training session or a deep clean. Convertible bench tables and fold-and-roll booths work the same way.
