Mattress sizes in the UK

Around the world, when we're looking at finding the correct size for our bed we're actually talking about mattress size. When you buy a 5'0" bed (or 150cm for Europeans), you're actually saying that the mattress size would be 5'0" and the bed would be sized appropriately by the manufacturer to fit the mattress size. When we're talking about bed sizes we really just want to know whether it would be too big for the room, or in certain conditions too small.

Identifying a mattress size is a lot more personal and you want to make sure it's the right size that it's not too cramped. This can quite negatively affect sleep and cause unneccessary tension if there are more than one person is sleeping on the bed. Personally, I've also found that beds which are too big can feel a bit isolating.
