We bought this for our three boys, currently ages 5, 3, and 1. It took my husband about twelve hours, working alone, to put it together. We've had it for about three months now and absolutely love it. It seems very well made and I expect our boys to get a decade or more of use out of it. Everything on it could be enjoyed by kids much bigger and older than mine currently are so I expect them to still be swinging, sliding, and climbing for many years to come. I think it's a great investment to encourage outdoor play. This set has so much it really feels like we've brought the playground to our own backyard.
