They say we spend a third of our lives sleeping, but experts say a good quality mattress isn't enough as they may be crawling with bacteria.
Not only can an old mattress give us backaches, experts say they harbour bacteria such as E coli and mould. These germs can cause sore throats, itchy eyes, diarrhoea, vomiting and even more serious infections like pneumonia.
A bed that's seen better days can cause achy back and a string of sleep problems. That's not to mention all the microscopic activity going on unbeknownst to us can give our immune systems a beating.
