A bit of a pain, but can you go back to the MFI showroom, open a base unit
and have a look on the underside of the worktops. You may have to look in a
few displays but sometimes the manufacturers print their name on the
underside, take a torch as they are not always in the easiest place to see!
Failing that try a Google on the EXACT name of the worktop.
