A mattress cover is a removable piece of bedding that helps preserve the lifespan of the mattress by shielding it against spills and secretions and in some cases, they also provide protection for the person using the bed against allergens, dust and bed bugs.

A waterproof mattress protector is designed to prevent urine, sweat and other liquids from getting onto the mattress which in turn reduces the likelihood that stains or mould occur. They usually have a layer made from a waterproof coating such as polyurethane and are simply popped into the washing machine and line dried to clean.

They are definitely a worthwhile investment for your child's bed. For babies and toddlers in cots, they protect against nappy leaks, dribble and sick and, as children get older, they safeguard against the odd accident which could lead to a bed with an unpleasant smell if it reaches the mattress.

There are plenty of waterproof mattress protectors to choose from so we have made the task of choosing the best mattress protector for your requirements as straightforward as possible by putting together a list of the most highly recommended ones.
