:lol::lol::lol: The only thing with the Tesco ones is that they don't come with any straight edging pieces - which is fine if you don't mind having the jigsaw edge along the sides (or you could cut them off but it would make the tile smaller).
Nicki, they're just called foam mats I think.
And, happysaz, they're very easy to clean - I just give them a quick wipe down but somebody else said they're easy to hose down. They don't seem to stain either - any poo or pee stains I've come across have come right off.
Pie, the trays are by Savic as already said. :wave: I got mine from PaH - they don't sell these specific ones any more but they do have others with a rim in various sizes:

I have one of these in pale blue polka dot too but it's a tad too small for 2 bums really:

I had to get some to stop Bubbles weeing over the side too. :roll:
