All-weather HDPE panels make this four-pack suitable for a patio party one weekend and a conference room the next, since the material shrugs off rain, scratching and fading. A heavy steel frame with triangular bracing carries 330 lbs per chair. Each folds flat to 43 by 18 by 6 in and stacks for storage, with built-in handles for carrying and anti-slip pads that protect indoor flooring.
