What boot liner

Hi all , am looking for a robust boot liner for the non estate version.

I want as heavy duty version as possible so thin carpet or even rubber won't be up to the job. I'm thinking more along the lines of a rigid tray with fairly tall sides to protect the carpet on the sides.

I know Skoda do some types, and one looks ok ish, but bases on the picture in the brochure the sides aren't tall enough - more like a lip than sides!

Based on my requirements, does anyone know of such a boot liner / tray that will fit?

Thanks
