Just a point of order - almost no-one will have teak garden furniture. Not unless they've had it made from the decks of scrapped ships.
Teak is exceptionally rare and costs about 5x more than similar looking South American hardwoods. But they don't have the durability of teak.
If we had a set of genuine teak garden furniture, it would be by far the most expensive furniture in the house. Ours is metal & stone!
