“How many chairs do we need?” sounds like a simple question.
On a hospitality project, it usually is not.
The right quantity depends on how the space will be used, how many guests it needs to support, how furniture affects circulation, and whether every seat actually needs to be occupied at the same time.
When designers ask us how much outdoor furniture a hotel or restaurant needs, we recommend starting with the operation of the space rather than trying to fill every available square foot.
