These places will be free for any weather conditions to attack them and eventually the furniture will get destroyed. This furniture can be actually kept outdoors throughout the entire year without any adverse reactions due to rain, snow, winds or too much sun.

Nowadays synthetic, man made wicker furniture is the better option for winter. Usually natural wicker furniture is great for summer but it's not so great for keeping it outdoors in winter. Wicker furniture can be made of rattan, cane, fiber and many other materials. Usually in bad weather it needs to be taken indoors to protect the material from the harsh weather conditions. Some people spray it with various sealants in order to waterproof it, however in the long run this is not the best option. The wicker weaving mean that through the actual weaving process, there will be many tiny places where the sealant will not reach no matter how much you try.

When you see an outdoor furniture and you realize it's 'wicker', it's actually not the type of the material but the style of weaving it together to get the final piece.
