Very sturdy. Great height for my 2.5 year old. He loves to draw on both sides. It would have been nice if whiteboard markers and an eraser (suitable for both sides) had been included. Also, there needs to be more of the common letters (a, e, l, m, n...). For example, I can't spell out my child's name because I need 3 N's which are not available.I don't think the mathematical operations needed to be included for this age. Perhaps, more letters and numbers would have been more suitable. Both sides are very easy to clean.
