Here are a few ideas for recycling an unwanted mattress
Trampoline Small children love bouncing on an old mattress, but make sure they take their shoes off first and that there are no sharp objects nearby.
Truck away bed Keep an old mattress under the bed. When unexpected guests spend the night, pull it out and make it up - it will be much more comfortable than sleeping on a blanket on the floor.
Door protector If it is a tight squeeze to park in your garage, nail a mattress to the wall to prevent damaging the car door as you open it.
Party accessory Put out an old mattress indoors or in the garden for children to bounce on; they can use it as seating when they eat their tea, too.
