I have to laugh at some of these reviews. One reviewer states they are flimsy. They must be trying to stand on them themselves? Another says no way they will fit a 4 year old. Well, I suppose that's why they are rated for kinds under 3. Our son loves to sit and watch cartoons in his custom sized chairs. They have proven very durable, getting smashed into by ride on cars, full size dogs, etc. Dirty? take them outside and hose them off. Perfect for our toddler.
