So once you do decide on your favourite mattress, make sure you get the most life out of it by protecting it with a waterproof fitted sheet or mattress protector. This will protect your mattress from sweat, drool, vomit, blood, spilt drinks or any other messes life my throw at it.
You can also use waterproof sheet protectors that give you extra protection with the benefit of quick and easy changes in the middle of the night.
