Wicker chairs are just one form of popular cane-style furniture - the others in this category include bamboo, willow and rattan. Wicker furniture has its advantages - it's extremely lightweight and versatile, however because of its flimsiness it's more susceptible to the elements and tends to wear down quickly if left outdoors.
If you do plan to feature wicker furniture on your outdoor patio, you'll want to fit your wicker chairs with weather resistant cushions. These can be easily cleaned with a sponge and warm, soapy water then air-dried. A wicker chair costs between $50 and $150 online.
