What is the minimum width of any seat according to PD 1096?

The minimum width of any seat according to PD 1096, also known as the National Building Code of the Philippines, is established at 450 mm. This specification is designed to ensure a comfortable seating arrangement that accommodates a variety of body types and sizes, promoting accessibility and usability in public spaces, including theaters, schools, and other venues where seating is crucial.

Seats that meet this minimum width are more likely to provide adequate space for users, enhancing both safety and comfort. In contrast, options indicating a smaller width, such as 400 mm, would not comply with the established standards, potentially leading to discomfort and safety issues for users. Hence, the correct answer underscores the importance of adhering to these regulations in building design to ensure a welcoming and functional environment for all.
