This un-finished cart  is made of  very solid wood.  I expected it to be a bit wider and the shelves less deep but I didn't actually measure before ordering it.  We are using it as a movable bookcase and it is deep enough to put two layers of books per shelf.  However, when rolled across carpet, the books tend to shift and fall of the ends.

I used Minwax stain and sealer in one and it took quite a long time to no longer feel tacky...that is a criticism of the stain and not the cart!  This would be a great small movable island in a kitchen or can hold a full sized micro wave. It does not work particularly well for a bookcase but again, that's my fault as it wasn't made to be one.
