Which mattress size is best for you? What is the difference between a queen and a king or between a small single and a single? Since Dreams are in the business of providing customers with comfort in many different sizes, we thought we’d show you the variety of mattresses size available.
Mattresses have undergone a colourful evolution over thousands of years. From humble beginnings where they were simply leaves piled in the corner of a cave, to feather-filled bags of silk and velour in medieval castles, to the multi-layered monuments of comfort that we know and love today, mattresses can fit any room and any person.
Below you will find a guide and to scale comparison of every mattress size as found in our Bed and Mattress Guide.
