Recycling mattresses

Visited the reuse and recycling centre this week to deposit some of my own recycling. Discovered that it is even possible to recycling mattresses and that the centre has a skip for mattress deposits. Apparently they are stripped down primarily for the metal springs.  Bed bases and mattresses seem to be the main item for dumping in front gardens and on pavements, when a call to the council for a free collection (020 8937 5050) would mean the mattress could be recycled, when mattresses left dumped on a pavement would probably be rejected as contaminated.
