Mattress Size Guide

The size of your mattress is one of the most important decisions you need to make when which one to buy. With so many options available, it can be overwhelming trying to make a final decision. Remember to choose a mattress at least 10cm longer than the height of the tallest using it. The width of the mattress should allow you to be able to put both your hands under head without your elbows touching the edge of the mattress. Finally, European bed sizes differ UK sizes, so ensure you check the dimensions of your bed.
