I've seen these plastic yellow / white / red ones in lots of cafes/restaurants but keep forgetting / losing the name of it when I get home and don't seem to be able to find out on retail/ consumer websites so maybe it's sold mostly to businesses. It's quite chunky, doesn't seem to fold, is very wipeable and has a large tray (Oh, and it may have blue in it too).
I think it may have an l,x and i in the name.
I know it's a flaky ask but does anyone know what the one I'm thinking of might be?
