What size mattress do I need? A guide to help

Choosing a size is step number one when shopping for a new mattress. And to make sure you’re comfortable at night, there are a few basic guidelines to look for when finding the perfect size.

You should ideally have about 10cm between your feet and the bottom of the mattress when lying flat on your back, with your head on the pillow. And when it comes to width, you should be able to slide both hands under the pillow when lying on your front, and not have you elbow reach the edge of the bed.
