A pocket sprung mattress is quite simply the very best that money can buy so you will want to ensure that you get the best possible discount.

Each spring acts independently to allow the contours of the body to be gently supported.

Pocket springs are rows of small diameter, 16 to 17 gauge wire, parallel or barrel-shaped springs, each housed separately in a fabric pocket.  The rows of springs are then clipped, tied or glued together.  The spring count of a pocket sprung mattress can vary considerably depending on the diameter of the springs.  In general, a spring count of between 900 and 1475 are the most common.
