But the London Underground know that they can make a mint from our love of all things tube, so not content with just upholstering the Tube seats with some eye-boggling designs, the moquette, as London Underground upholstery is called - now adorns a whole variety of consumer goods from the cushions above to dog coats
(Thanks to Will for the best & funniest "definition" of moquette that I've seen. For the London Underground's historical background of these "aesthetically pleasing materials" see here)
We even wax lyrical about when new seat designs come out on the Tube. See James Cridland's comments on the new Piccadilly Line seat designs in his flickr post - "Presumably, they're darker so they don't show the poo stains as quickly.."
However my personal "favourites" are the ones seen on the Circle and Hammersmith and City Line, which I think are deliberately designed so hideously so that pigeon droppings and general vomit from drunks doesn't show up on them.
And that's not a photo-shopped picture, the pigeon was really on the seat!
