Choosing the Right Double Mattress

A double mattress is the most popular mattress size in many UK homes, offering a comfortable sleeping area without requiring the extra bedroom space of a king size mattress. Measuring approximately 4ft6 wide (135cm x 190cm), it provides an excellent balance between comfort and practicality.

When choosing a double mattress, consider your sleeping position, preferred firmness, body support requirements and the materials used within the mattress. Our collection includes traditional sprung mattresses, advanced foam designs and premium hybrid options.
