It's been on the patio for about a month now and it still looks brand new.  What sold me on it was a review that someone else wrote that said she has it at a beach house and just hoses it off when needed and that it's held up well.  So, I am confident that when the time comes, I can just hose it off.  It laid perfectly flat as soon as I unrolled it which made me happy because I had company coming over that first evening.  I've had lots of compliments on it.  And, it was such a reasonable price.  I could not be happier with this purchase.
