Leaving synthetic rattan furniture outside in the snow is generally acceptable for short periods, as most modern pieces are designed as all-weather wicker. However, prolonged exposure to heavy snow, ice, and freeze-thaw cycles is not recommended. While the synthetic material itself is UV-stabilized and moisture-resistant, the structural integrity can be compromised. The weight of accumulated snow can stress and potentially deform the frames, especially on hanging chairs or sofas. Constant moisture can lead to mildew on cushions and, in some cases, seep into screw holes or joints, causing hidden damage over time.
For optimal protection, it is best to use high-quality, breathable furniture covers that are securely fastened to prevent moisture buildup and wind damage. If possible, moving furniture to a sheltered area like a garage or covered patio is ideal. Always ensure the furniture is clean and completely dry before covering it for the winter. For extended snowy seasons, elevating furniture off wet ground and removing cushions for indoor storage will significantly extend its lifespan. With proper precautions, your synthetic rattan furniture can remain a durable and stylish part of your outdoor space for many winters to come.
