For the price I would have expected the walls and doors to be made of something a bit sturdier than what seems like a thick piece of painted cardboard. I expected particle board given the price, yet the only pieces that are made of board are the top, bottom, center upright and shelves.  The sides have particle board edges and cross beams, the rest is just a board.  The whole back is 2 large planks of the same material.  

When assembling, make sure you don’t over tighten, particle board will either get damaged andor your screw will not hold.

Also good to have an extra set of hands, gets difficult to move it around especially at the end without potentially warping the whole thing.

The size and finished look is nice.  I like the deep shelves.  Not a sturdy piece... definitely not good for someone with a heavy hand.  Gotta be gentle with the doors.
