out door furniture

last month

Hello, we are looking for outdoor seating/ dining furniture for our alfresco area. however, the area faces dead north and is open on the north, east and west sides so it cops most weathers. we have an outdoor fireplace so we can use the space year round(we live in tassie). I'm wondering if anyone knows what would be the hardest waring type of furniture to have in this area that's not going to blow around in the wind or get damaged in the cold and the rain. I like the look of rattan couch style chairs but wondering how long they'd last.
We are temporarily using stackable chairs from bunnings and been saving up for something nice :)
