search for Hartman garden furniture, we have had ours a couple of years and still looks good. Most garden centers stock it if you want to see it in the flesh but then order online. We saved £200 on ours.
We got a patio set from Argos a few years ago and it honestly looks brand new. The table is a bit annoying as it doesn't have a flat surface but it has all lasted really well considering it is out all year round
