The “wood” pieces are particle board, but for the price that’s what I expected. I recommend using your own tools, we used our power drill and it went a lot faster.  We purchased two book shelves and two matching desks.  The matching desks we bought were by different brands (Trent Austin  Laurel Foundrey), but they matched and had the same manufacturer tags once we opened the box.  The desks were intimidating at first as they come with a ton of pieces.  It took us about 1-2 hours for each desk and about 30 minutes for each book shelf.
