I bought this for my 4 year old niece and my 2 year old nephew and it was an immediate hit! I was nervous about the size of it, but so far we have assembled it in two different houses with no problem! Assembly take just a few minutes. I was very worried about my brother and sister-in-law trying to fit this big box in their car as they drove back home, but the sturdy, large pieces tucked away nicely between their suitcases. I cannot express how very, very much the kids loved this item and even the 2 year old can do everything for himself on it (with only visual supervision from his parents) - no need to lift him on to it each time! I HIGHLY recommend this product!
