I received the Fisher Price Gymtastics Play Wall as a hand-me-down. I pull it out and put it together when we have guests over to our house who have a small child. I have found that around the age of six months seems to be the perfect age for this toy - or when a child can just start to stand with assistance. The play wall is sturdy enough for a six month old to hold on to it while standing; the play wall will not fall over, as it has very long "feet" to keep it in place. There are many removable rattles that can be placed in different spots along the play wall. There is also a sound component where certain movements (such as moving one of the hanging cylinders) triggers a little noise. The children really seem to like this part. Like most toys, it would be nice if there was a volume control so that the noise isn't so loud. We ended up putting tape over the speakers to muffle the noise a little. Overall, this is a great toy.
