The upholstery, or filling, of a mattress is one of the most important parts of its construction. Mattress upholstery is the subject of much research by mattress manufacturers. Finding the right combination of materials for upholstering mattresses can have a significant effect on the finished article, both in terms of its durability and the support and comfort it offers. When you're looking at new mattresses, check out which fillings have been used, as this can give an indication of the quality of the mattress. Mattress upholstery is a complex science, because different materials are used at different stages to achieve the desired goal. Whether it's the filling that's packed around the coils to keep them in place, or a layer that goes on top of latex foam in order to provide a luxurious feel to the mattress, each material has its own characteristics and uses. Modern mattress upholstery Whilst straw and hair may have been the fillings of choice for the very first mattress-makers, technology has advanced to the point where manufacturers can choose from a wide range of both natural and man-made upholstery materials. Natural fillings are often preferred because they have useful characteristics such as: ? Breathability ? Warmth ? Softness ? Protection ? Resilience ? Springiness ? Quick recovery ? Temperature control For example, a mattress manufacturer may make an open or continuous spring mattress. Once the coils are in place and secured together with additional wire, they may be packed with coir fibre. This is produced from coconut husks and is one of the most versatile natural fibres. Coir fibre helps to keep the springs in place and provides a barrier between the springs and the sleeper, preventing them from pressing through the rest of the upholstery and disturbing your sleep. Once the fibre is in place, the mattress might then receive a layer of teased hair or wool. This enhances the springy nature of the mattress, whilst also providing excellent insulation and temperature control characteristics. The mattress upholstery may then be completed with a layer of soft, natural cotton, which gives you the comfort you are looking for when you lie down. Manufacturers have a great deal of variation in the way they choose to upholster their mattresses, and are constantly looking at ways to improve so that they can provide you with best possible sleeping surface.
