Thanks for your input Boyan,
Do you mean phenolic plywood? Ebay number 162227405235

Or could you find one and post a link/number?

Thanks Kamil

Thanks, my main concern is that since its plywood coated in something, won't the plywood absorb moisture around the edges and swell?

[Boyan Silyavski]

Its not plywood coated in sth. Its Tufnol or Pnenolic sheet paper based. I was not saying Phenolic Plywood

Looking at the link you posted, all I can see is phenolic plywood. Could you find a listing for the stuff that you are suggesting?
Thanks Kamil

Look for product called Trespa Athlon.
It's Resin based fibre board that is very muck like Pnenolic board but with laminate face. Completely resistant to moisture, chemicals, heat. It's used in place like swimming cubicles, counters for Labs etc.
It can even be drilled an tapped. I use it for Spoil board on my own machine which is constantly covered in cutting fluid. All work is help down by drilling and tapping directly into it or by clamping using holes tapped into it.

Not cheap but extremely resistant and tuff stuff. Nothing better for bed IME.

The stuff Boyan and I were talking about is Tufnol 1P13 like as here https://www.directplastics.co.uk/tufnol-sheet. They do all sorts of engineering plastics.

Boyan pulled up the link just afore me.

Thanks, would you say a 12mm thick sheet will be rigid enough for my application?

I had a look at this Trespa Athlon stuff and it's not cheap or easy to come by so I'll pass on that.
