Solid wood, pretty good quality cabinet for the price.  I had to buy my own cabinet screws though and center it on the wall while accounting for the studs by hanging the cabinet through the back panel rather than using the pre-set hanging hooks that are drilled into the cabinet.  So unless your studs center perfectly on the built-in cabinet hooks, aligned to where you want the cabinet centered on the wall, then be prepared to do a little extra work, which would include stud-finding, taking measurments and figuring basic math, using a level, using something to hold the cabinet up while you hang through the back panel etc.
