Upright post will need some reinforcement. The kids also leaned to hard on the back rest and pulled the screws out from the back rest.  My husband is handy... and made it stronger. The canvas also blew away with a good wind storm we had, I was able to make another using outdoor fabric and marine grade snaps. That sucker is not going anywhere now :) For the price, it is great if you live in a non-windy area and your kids play politely. But with few extra screws I think it will last for awhile now!
