You could also look at buying a Youth Chair which is great for longer use and you don't have to worry about it scratching your matching chairs. You could also paint it really cute to make it special for your little boys. This is a link to one I a site that makes them but you could probably find at Neal's Furniture in the Raw or another wood furniture store.
