i know the cot matress has always been kept inside the house, never in the loft or garage or shed.
it is a mamas and papas for what its worth, wheevr that means anything i don't know
not sure what the guidelines are atm
but a bit under whever to use it or get a brand new one.
i've also seen what looks like a good buy on a travel system on ebay for about 30pounds.
what do you think?
