Showing Coil Springs Latex or Gel and matching £0 - £200
The Bonnell Spring Unit is the most common spring unit and consists of hour glass shaped springs, linked top and bottom by a spiral wire which runs across the finished unit. The unit will then usually have a retaining wire that is clipped around the perimeter of the mattress, top and bottom, called a rod edge. This provides the edge of the mattress with extra support. Economy beds may have a plastic as opposed to a metal rod edge and some have none at all. The thickness of the wire used in the construction of the springs is known as the wire gauge. The higher the gauge, the thinner the wire will be and therefore the softer the mattress will feel. Most Bonnell units use a 13 gauge wire. A few orthopedic models will use a 12 or 12.5 gauge as a thicker wire will make a firmer spring. You can also have a spring system called Sleepzone or Miracoil (the famous Silentnight spring system) this is similar to the above however the springs run top to toe and normal have around 600 springs per 5' model. Latex is a natural product which we are finding has an increasing appeal. Like memory foam it reacts to heat allowing perfect body anatomy whilst sleeping. However it does not retain heat like memory foam giving so gives you a much cool sleep. Gel is the great new choice for restful sleep. Gel is the softest solid on the planet today. Developed for medical use, it is now a preferred choice of mattress filling - 15 times cooler than memory foam, it absorbs heat and with its amazing durability it conforms to the sleeper's body shape night after night without losing elasticity.
