High Density foam mattresses are generally lightweight and non turn making them very easy to manage. Foam mattresses are normally thinner than sprung interior mattresses. This makes them ideal for use on bunk beds, cabin beds and high sleepers where there are mattress safety height restrictions.

Foam mattresses are 100% hypo-allergenic and antibacterial making them ideal for those that suffer from asthma, hayfever and other related allergens.

Bonnell Sprung

Bonnell springs are used in budget to mid range mattresses. They consist of rows of springs connected by a helical wire all set within a wire frame.

A bonnell spring mattress will give the sleeper a flatter bouncier sleep surface. Firmer mattresses will use a 12.5 gauge spring while softer mattresses will use a 13.5 gauge spring.

Pocket Sprung

Pocket springs are generally regarded as the best springs for providing good support in a mattress. Spring counts can be anything from 1000 springs up to almost 10,000 springs.

All the springs are individually encased in fabric pockets and nestled into the mattress. This means that each spring works independently from the next so that the mattress can shape itself and support each sleeper’s unique shape and contours. An added benefit of this is that the mattress has good motion separation. If one person is having a restless night or couples are of different size and weight they will not disturb their sleeping partner when moving around.

Memory Foam

Memory foam mattresses are made up of a layer of memory foam on top of either springs or high density foam. The Memory foam or visco elastic polymer cushioning as it is also known is designed to mould to the individual contours of the body so that a greater area of the body is in contact with the mattress which will reduce the pressure points, in particular shoulders and hips.

This in turn will reduce natural tossing and turning during sleep because the body will have less need to adjust and relieve pressure points ensuring a better nights sleep. Memory foam is also hypo-allergenic and antibacterial making it a good choice for allergy sufferers.

Gel works very much the same way as memory foam with it’s pressure relieving and moulding qualities. Added to that gel also addresses the issue of getting hot in bed. Gel mattresses dissipate heat and moisture away from the body to keep you cool and comfortable when sleeping. Gel is up to 30% cooler to sleep on when compared with standard memory foam.

ThermaGel technology is now the latest leap forward in gel comfort with phase change properties. ThermaGel not only conducts excess heat away from the body, it also releases warmth when your body temperature gets too cold. The reactive phase change materials work to keep your body near to 30º celsius which is the ideal sleep temperature.
