The Mattress Dimensions and Bedsizes Guide

    Adult couples or single sleepers who are looking for a mattress size they won't outgrow but that is not as tall or wide as a king bed.

   Often considered the best type by customers, Pocket Coil innerspring mattress is also referred to as pocket, encased, wrapped. This kind of bed consists of hundreds or even thousands of individual coil springs, each sitting in its own fabric pocket. As they are not attached to each other, the springs can move independently of each other. 

    This type of coil system conforms to your body, distributing your weight evenly and preventing pressure points that can cause shoulder and back pain. For this reason, pocket spring innerspring mattresses are known for providing supreme support. The individual springs also help prevent motion disturbance, as, if you move, your partner does should not feel it on their side.

    Due to these highly desirable features, pocket spring innerspring mattresses are usually the most expensive of all four types but there are some really affordable brands out there.

     Mattress sizes vary from country to country. Bed sizes also vary according to the size and degree of ornamentation of the bed frame. Dimensions and names vary considerably around the world, with most countries having their own standards and terminology. In addition, two mattresses with the same nominal size may still have slightly different dimensions, due to manufacturing tolerances, amount of padding, and support type.
