If you find yourself fidgeting after minutes at your desk, a better choice in seating might be the solution. Even though you're working indoors, hot summer weather makes sitting in an unventilated seat more difficult. A chair with heavy upholstery and thick padding creates a trap that holds heat close to your body. One of the biggest benefits of a mesh chair is its ability to ventilate air away from your body. It helps you keep your cool even in the hottest of weather conditions.
