Pocket springs are the foundation of high-quality mattresses and are a fundamental component that any mattress buyer should fully understand. The key thing to remember in this section is that pocket springs, types and counts should not be taken in isolation. Read on for all you need to know about pocket springs and why assessing their quality is essential to helping you find the right mattress.
WHAT IS A POCKET SPRING?
A pocket spring is a case, usually made of fabric that encases a wire spring. These cases are either stitched or in cheaper models, glued together to create a length of individual springs that are connected. This enables a sleeper to be supported independently by each pocket spring. It’s great to prevent movement between sleepers and will enable you to have far greater support than a cage sprung or open coil mattress.
The highest quality pocket springs will be calico encased and the spring wire will be vanadium plated. This enables them springs to breathe and prevents heat build up.
THERE ARE TWO MAIN TYPES OF POCKET SPRING
1.Synthetic spun bond springs – the entry-level spring unit. Glued together with a polyester style material. The least breathable and responsive.
2. Calico encased pocket springs – Encased in a breathable natural calico cover which are then stitched together. Highly responsive and much more breathable.
Calico pocket springs are quite simply the highest quality spring you can get in a mattress. All the high-end manufacturers, such as Savoir beds, Vi-spring will use calico pocket springs in their top end ranges. Each spring is housed in a calico cover, this provides more flexibility than the synthetic spun bond counterparts meaning the springs can flex easily and breath more than cheaper pocket sprung units. The calico pocket springs are sewn together and are only attached to adjacent springs with lengths of twine stringing them together. This is always done by hand by a skilled craftsman.
