We bought this when our granddaughter was 1 year old. She’ll be 12 in a couple of months and we now have 3 grands. My hyhas taken great care to make sure it is stained every couple of years and it’s still beautiful. The wood on the top on the rope ladder was not as thick and didn’t make it but overall the best that money can buy. Our had the poly coated beams( now referred to as Timber  Shield.  It’s a must for protection and durability. I wish the whole set had this coating as the beams and posts that do are completely maintenance free. It may even last until we have great grands!!!
