When arranging furniture always make sure to keep plenty of space for traffic to flow through a room. Some rules to remember? Walkways should be 27” to 36” wide to allow people to pass through a space. Coffee tables should be no more than 18” from a sofa or chair so people have enough room to sit but do not have to reach far for their beverage or personal items. Furniture items that are side-by-side, such as a bed and a night stand, can be as little as 4” to 6” apart since you do not need to walk between them.
