If you are truly looking for "quality" furniture, shy away from particle board or particle board veneers in the construction. You can often tell by looking at the back, ends or bottom of the piece, although manufacturers are getting better at hiding it. However, be prepared to pay.
Careful how you ask the question ... ask specifically whether there is particle board in the construction ... in Texas, if you query a salesman with "Is this wood?", they can legally say "yes" (and will), even if it is constructed entirely from particle board (a wood product).
That is not to say that particle board does not have its place in furniture building and won't suffice for budget, or even mid priced pieces that are certainly functional ... but I would hesitate to expect to hand those piece down to your grandkids.
After a recent flood, any furniture in my house containing PB in the construction was considered an immediate and total loss by the insurance company, no further questions asked. ALL the "real" wood pieces were salvageable with a minimum of restoration for the most part.
Cabinet grade plywood is acceptable, maybe even desirable in some areas of the construction for its dimensional stability, although the absolute best furniture seems to be made entirely of wood with as few steps as possible from the tree.
Again, be prepared to pay for wood construction.
