For info: Snow and Rock outdoor shop in south manchester are clearing out some old stock. They have the 3/4 size guidelite mattress (burgundy) on sale at half price - making them £30 each. As of Friday night 11th they had several in stock. It's a pretty good deal if anyone is shopping for these. There were plenty of full size mattresses too, but only in the thicker / heavier models, not the guidelite version.
