I gave this to my 11 yo daughter for Christmas. It did take probably about 6 hours to assemble but the parts were clearly labeled and the directions were easy to follow. It is a heavy, sturdy piece of furniture; it takes two people to move it. Almost 5 most later and the lights work great and everything but the stool remains perfect. I did have to replace the stool though; it did not withhold my daughter scooting it in and out.
