I love love love love love there. I did buy the  extra 3 year warranty. Got 6 one piece and two of the thicker ones with the back cushion for the love seat. They are very comfortable, durable and I love the "MacKenzie Child-esq" look! 
We do bring them in when we aren't outside so haven't left them in the rain and haven't had any spills or stains to remove yet, so hope that part goes well, but I highly recommend them as with the feel of the fabric and the warranty, very confident. I paid a bit over 1000 including GST for all of them. Not cheap, but not expensive.
