I sleep under a skylight, which I left open last night to cool the room down, expecting it not to rain. It did rain, and after first collecting on the window the water streamed directly onto the end of my bed, soaking through the duvet and mattress protector to leave one patch of the mattress (an Artisan Luxury) feeling very damp.
Is this likely to do serious damage to the mattress (e.g. causing mould?) and do you recommend any particular techniques for drying it out?
