UK Mattress Measurements

There are six standard UK bed mattress sizes. Mattress length and width is commonly referred to in the retail industry in Imperial units (4ft6 Double, for example) for the sake of simplifying the difference is size.

UK Manufacturers, however, produce their mattresses in Metric units (centimetres and metres) as a standard. This is why you sometimes see both units referred to, and we have included both below for easy conversion should it be required.
