I purchased 3 gliders for my 3 year old triplets.  They haven't figured out how to use the glider on their own but they enjoy me pushing them.  I hope they figure out how to swing without me pushing shortly.  It's very sturdy, but with that has come a little down side, they can knock each other out if they get hit by another glider.  I'm sure that won't be as big of a deal in the next few months once they get the hang of it.  Overall I'm happy with the gliders and hope this keeps the kids interested in the play set for years to come.
