box for reading stand (Britannia)

For many years, I've used this upside-down basket to support my book stand – so I can read while I eat (because I live alone).

But now it's starting to fall apart, and I'd like to replace it ... hoping somebody here can suggest something?!

My ideal would be a plain wooden box, with a flat top, about 6-8" high, and roughly a foot across.

Such a box should be nice enough for my dining table (or at least not too wretchedly scruffy).

I might possibly find something decorative at a fancy home-goods store ... but it would likely be expensive!

Any suggestions (or boxes) gratefully received.

Thanks,
A.
