If you live in a location that’s warm year-round, you can leave your chaise lounge outside through all four seasons. But if you live in a climate with snow and other inclement weather in the fall and winter, it’s best to put your chaise lounge in storage when you aren’t using it.If you don’t have room to store your chaise lounge in your garage, shed, or basement for the winter, use a water-repellent patio furniture cover to keep the chair safe from the elements. Make sure it has sturdy fasteners to keep the cover in place in strong winds, too.
