Spring Interior Mattress

The majority of mattresses sold in the UK have a spring interior, the springs therefore provide the ‘core’ support and the comfort is determined by the quality of the fillings on top of the spring unit.

Of course not all spring units are the same either, they can usually be split into three main categories.

Open coil or open sprung

This is the most widely used type of interior spring unit.

Springs are arranged in rows and connected to one another, top and bottom, by a spiral helical wire with an outer rod strengthening the perimeter.

Continuous spring

The continuous spring unit is made from a single length of wire “ knitted” into a series of inter woven springs which usually run up and down the bed and are linked vertically rather than horizontally.

Pocket Spring

Pocket springs are individual springs housed in fabric pockets allowing them to work independently from one another, this allows the springs to profile to the body shape which can help to prevent pressure points.

Independent support means that there is little or no transfer of movement from one sleeping partner to another. Spring counts typically vary from 600-800 up to 2,500, with some luxury beds having even more.

Pocket springs are generally more expensive than other types of spring units and are used mainly in higher quality products.
