I bought this for my grandchildren aged 3-1/2 and 12 months old. It was easy to assemble and the instructions were clear though a little confusing with all the different languages figuring out which pages to follow. The kids absolutely loved it and the baby immediately started climbing up the slide while her older brother climbed up the "steps" and had fun sliding down over and over. It was a great for the two to be able to play together and practice sharing, taking turns and mastering new skills. Tossing the basketball toss into the hoop was a hit with the 3 year old. We didn't have a bicycle pump so couldn't blow up the ball provided, but, fortunately, had another ball just the right size. The climber was just the right size to use in the house or outside and was light enough and sturdy enough to move to different locations. The set is designed for ages 2-6 and our 12 month old needed constant supervision but had a lot of fun. The sweetest thing was when big brother waited at the bottom of the slide to catch his sister after she slid down with her mommy's support. So sweet to see the big smiles and hugs. As a recommendation.
