Best way to pack/store bed? need advice before this afternoon!!

[sleepychunky]

We are starting to sort out spare room this afternoon in preparation for moving DS in there before the arrival of new baby. We have a double bed in there at the moment which we are planning on keeping in the garage until we can bring it back inside.
What's the best way of wrapping/packing it so that it won't get mouldy/infested etc?? Also have mattress - does that need a different type of wrapping?
Any expert movers please help! TIA

not sure but you can get specific mattress wrapping from places like Access self-storage e.g. Mattress Cover, don't know how long-term that is though.
