What is the minimum back-to-back distance for chairs according to PD 1096?

The minimum back-to-back distance for chairs as specified in PD 1096 is 850 mm. This dimension is crucial for ensuring adequate space for occupants to sit comfortably without feeling cramped, allowing for ease of movement when entering and exiting their seats. Such measurements are aligned with the intent of building regulations to provide safety and comfort in public and private spaces, addressing both accessibility and usability.

This particular requirement also helps facilitate the movement of individuals with mobility aids and ensures that traffic patterns within an area are not obstructed by seating arrangements. By adhering to this standard, designers and architects can create environments that promote better interaction and flow among users. The selection of 850 mm is thus a reflection of practical standards garnered from experience in designing functional environments.
