In his book "At Home: A Short History of Private Life," Bill Bryson discusses various design flaws that contribute to accidents, particularly in relation to stairs and other fixtures in homes. He notes that poor lighting is a significant issue, making it difficult for individuals to navigate safely. Additionally, the lack of handrails can pose a serious risk, as they provide essential support when ascending or descending.

Bryson also points out that confusing patterns on stairs, inconsistent riser heights, and irregular tread widths further complicate safe movement. He highlights that landings that disrupt the flow of stairs can also lead to falls, emphasizing the importance of thoughtful design in preventing accidents at home.
