If you are prepared to spend a small amount of money, wait some months and
have an Aldi near you. Then when they have their next offer of wooden chests
containing 6 drawers (at about £18? each), buy 3 or 4. The small drawers are
about 12"w x 14"d x 3"h and are all wood construction. By not installing
the drawer bases and adding some corner posts, a variety of depths can be
achieved. These units are castored and are IME just the right height to go
under a workbench, or can be arranged in a workshop in a variety of manners.
They are strong enough to stack if this is required. Be prepared to join the
queue early on the morning that they are offered, because in my local shop,
they sell out in about 5-30 minutes!! BTW Keep the units away from your
wife's sight, or you will likely lose them for one of her requirements!!
