Ideally, you will store your chairs when they are not in use. Otherwise, the maintenance of each type of chair will depend on the material they are made of,” Dedrick says. Barnard suggests “limiting their exposure to the elements and keeping them covered when not in use to protect them from sun and moisture. Regularly wiping down furniture and flipping cushions will help to contribute to its longevity.” “In the off-season, covering pool chairs with furniture covers and storing them in a temperature-controlled setting will help keep them from collecting moisture,” Barnard explains. “Leaving them outside but covered in warmer climates may offer accessibility on days where outdoor seating may still be pleasant, even in cooler seasons. In areas with winter and snow, garage or shed spaces will help protect furnishings from moisture and intense climate shifts. However, check on stored furnishings regularly as they may be exposed to moisture and mildew in storage.
