We can dispose of your old or unwanted mattress, divan or bedstead when you purchase a new one from M&S. Just add this service to your basket when you make your purchase and we’ll collect your old bed (if you’ve bought a bed) or mattress (if you’ve bought a mattress) when we come to deliver your new one. All mattresses are sent to be recycled and 97 to 100 per cent of the components are re-used.
