The characteristics of a mattress are mostly dictated by the build, the main types are
Cage sprung or open coil mattresses are built with a system of connected springs, arranged in rows and connected to each other at the top and bottom by a helical wire. An outer rod is sometimes added to the perimeter of the spring unit to strengthen the sides of the mattress. Cage sprung mattresses come in a large variety of tensions, from extra firm to softer.
In contrast, pocket sprung mattresses contain springs that are housed inside individual fabric pockets, allowing them to work independently of each other. This arrangement tailors support from the centre of the mattress to the very edge, and means that there is significantly less roll-together when two people are on it. The number of individual springs vary. As a rough guide, a mattress with a greater number of pocket springs will be more supportive. Pocket sprung mattresses can be a great investment as they provide exceptional support. For example, the vast majority of orthopaedic mattresses feature pocket springs.
Famously developed by NASA in the 1960’s, memory foam offers great support as it moulds to the sleeper’s body shape. When new, memory foam mattresses sometimes have a faint odour. This is caused by the fire retardant spray used in their manufacture and normally lasts for only a day or so. Some customers have also found memory foam to be rather warm, so if you struggle with overheating, check out our range of CoolMax covers and Geltex mattresses.
