I have worked at the microscope while sitting on 50 year-old office chairs (doubtless at one time graced by far more attractive derrierres (8^D)).

I also wonder if, in the age of international terror, there is a market for 'bulletproof' cubicle panels...
But the bad thing is that if you try and move one of their file cabinets by yourself, you'll bust a nut.
