According to PD 1096, what is the minimum distance between the front of a seat and the back of a seat in front of it?

The correct answer is based on the requirements set forth in Presidential Decree No. 1096, which is known as the National Building Code of the Philippines. It specifies that the minimum distance between the front of a seat and the back of a seat in front of it must be 300 millimeters. This measurement is important for ensuring comfort and accessibility for individuals in assembly areas, such as theaters and auditoriums, where seating configuration plays a critical role in user experience.

The specified distance allows adequate legroom for the average occupant, facilitating ease of movement as well as compliance with safety regulations that may concern egress in case of emergencies. In settings where people may be seated for extended periods, this dimension contributes to overall patron comfort and can affect viewing angles and engagement with performances or presentations.

Given that this specification is a standard aimed at public welfare and design effectiveness, it is crucial to adhere to it in any construction or renovation plans involving seating arrangements. Other distances mentioned in the options are not in line with PD 1096 and thus do not fulfill the regulatory requirements.
