Spring 4 coil.png


IPS3 stands for Individual Pocketed Spring Suspension System.

In IPS3, the coils are placed in individual pockets, unlike the coils in a Bonnell spring or open coil, which are not laced together. This characteristic allows each coil to operate independently to provide a contoured support specific to the user’s body shape and sleeping style.  Another well-known feature of the suspension system is its capability to minimize the effect of motion disturbance, which benefits users who share their beds with their loved ones.


Pros: Durable materials and superior comfort

Cons: Sleepers should be equally as interested in the foam that is wrapped around the coil system - if that is low quality, the bed still may be uncomfortable

Pocket springs are individually wrapped coil systems that are stitched into mattresses below a comfort layer of foam or other material. Unlike traditional innerspring systems that are interconnected, pocket springs are entirely independent allowing for added contour and pressure point relief than older innerspring models.

The general rule on pocket coil systems is the more coils, the more responsive and motion controlled the mattress is, while still providing support. This directly translates to more comfort.

In most pocket spring beds, there is a layer of memory foam or latex foam above the pocket spring array so that the sleeper gets both the benefits of contouring foam and the comfort of the pocket springs.

Pocket spring mattresses offer more support than open coiled. The individual springs that make up the mattress are housed in their own little pockets and work independently of each other. Spring counts can vary dramatically from 600 to 5,000. Typically, the higher the spring count, the better the support.

Pros: Because the springs move independently they offer more support for your body, and are ideal for people of two different weights as pocket-sprung mattresses reduce that ‘roll-together’ feeling.

Cons: Can be heavy to turn, due to the density of their fillings. If you suffer from allergies, be sure to check the fillings carefully, as many use natural materials like lambs wool, which can aggravate allergies.

Pocket spring mattresses can last between 7-10 years.

Open coil (also known as Miracoil, Continuous coil, Standard coil e.t.c) are the most common types of mattresses, which consist of an inter-connected spring system. They are the traditional manufacturing method, capable of being mass-produced with a low production cost – this makes them one of the cheapest on the market. A standard open coil mattress contains an average of 300 springs.

Pros: Open coils provide excellent support and are used for most mattresses due to their firmness. They tend to have more ‘give’ than pocket sprung mattresses, and are lighter and therefore easier to turn.


Cons: Not as robust as other mattresses and can be known to ‘dip’ in the middle after prolonged use. Open coiled bedding can also lead to the ‘roll-together’ feeling for couples, and you will feel the movement of your partner.

These are great mattresses for children, lasting between 3-5 years
