In the cinema,we always encountered an awkward question.Cinema folding handrail is usually very narrow,can only put one person's arm on,if two people want to put their hands on the handrail,then someone had to compromise,or have a negotiate.If the handrail and seat shape was improved,the problem will be smoothly solved..The middle position of the handrail is mounted with a clapboard,two people sitting nearby without interference.The improved seat width does not increase,and material consumption is not significantly increased.This avoids embarrassment,two strangers can also use the same handrail in harmony.
