I bought this art table for my daughter for Christmas when she was 3, and she continues to use it on a daily basis at age 4.  Although a bit of a project, I was able to assemble it by myself (which I was super proud of).  The chairs can be a bit wobbly for me to sit on (135 lbs), but my daughter absolutely LOVES it.  I would strongly recommend this product.

Pros: large work surface, plenty of storage
Cons: bins are flimsy, and chairs not entirely stable for big kids
