Patio furniture is the best option for a long-lasting outdoor living room. While you don’t need to stick with traditional silhouettes (like a wicker sofa or Adirondack chair), you should invest in furniture that is designed for outdoor use.
Even accessories like an outdoor rug and throw pillows should be weather-safe. Upholstery meant for indoor use will quickly fade if left outside. It may also be more prone to mildew or mold if allowed to get damp.
