Hi,

If you read the bit in testimonials, there are children that are using it up to the age of 19 mths, i am pretty sure that when i was at the Expo the people that were there were saying that it can be used up to 24mths of age, even though it is a bit squishy in there, apparently the child loves to position and its good for their spinal development.

ETA: I also love the step idea and the fact that it is two different heights
