These blocks are perfect for a child just starting to climb on things! My 1 year old daughter loves climbing onto, over, across these blocks. We got them for her a few months ago and she even loves just sitting on them. The five different shapes are nice, but we really only use the big square, the little rectangle and the ramp. Maybe as she becomes more mobile she will enjoy the other shapes too. They also function nicely as the foundation for a tiny pillow/blanket fort.
The material seems to be of sturdy quality and the colors are bright and engaging. The foam is strong enough for an adult to sit on it without deforming excessively and it springs back immediately.
