Yes, we know, it looks like real wicker, but it isn't. It's better because it won't rot, doesn't need to be painted every year, and the frames don't fall apart with use.
The "wicker" is a resin product, hand-woven over never-rust aluminum frames. Leave it ouside rain or shine and you will still have it to enjoy for many years.
Most outdoor wicker requires the use of plush cushions which are designed to take full exposure to the weather without rotting.
Expect outdoor wicker to be in the moderate to high price range.
