SWMBO wants me to make some plywood boxes that she will then upholster.
They will be used for people to sit on (don't ask).

How about some construction ideas? They need to be sturdy, and thus
will need some kind of internal reinforcement.

Not necessarily.

Got a router, or a table saw with a dado blade? Glued and screwed/finish
nailed "rabbet joints" work well for plywood boxes, and even if you leave
one end of the box open, the joinery is plenty strong for seating. Not to
say that you can't use some cleats in the internal corners if you feel you
need them..

If finished appearance is a must, finger joints are strong and eye-catching
for any type of box, but you will need to use a good grade of plywood to
keep the splintering down. Same goes with dovetail joints.

Then there's always biscuits and butt joints, providing you're set up to do
them. If you don't have a biscuit jointer, maybe now's you're chance to get
one.
