Portable Regulating Bench

[Lewis Surdam]

Greetings,

There are two concert halls at Harvard where access to any kind of bench
is difficult to impossible and where storage room is at a premium. That
means using the top of the instrument which can be awkward. Can anyone
help me locate some kind of folding bench that is fairly solid yet can be
tucked away when not needed? The card tables I have seen are too wobbly
to work on. I'll appreciate any suggestions.

Thanks,
Lew Surdam
