Great unit I purchased the baby swings as my kids are only 9 months but they love it so far. The way they are growing by 4 years old they will probably be to big for it. It went together pretty easy in about 5 hours you will need a second person for certain parts of the installation. I gave it four stars because some of the holes were not drilled at all and I had to purchase a large drill bit and drill my own holes for a few of the pieces.
