I was so happy I ordered these for the swing set I bought my 3 year old grandson. I bought 2 sets ...1 set to go on the ladder and 1 set for the rock climbing wall. My grandson liked having them to climb up his rock wall. (The ladder is waiting for replacement pieces), it also have me the comfort of knowing there was something there for added safety. I think the price is worth the added safety for anyone buying a wooden swing set for a young child to explore and grow with. I also added the binoculars and telescope which he loves in his tree house. The phone we put in one of the wooden playhouses also bought.
