Open Coil Mattress
Open coil mattresses are the most common types of mattresses. Consisting of inter-connected springs they are the traditional manufacturing method for mattress. This method of manufacturing makes open coil mattresses more affordable as they can be mass produced.
The firmness of the mattress is measured by the thickness of the wire used for the springs. The unit of measurement is called a gauge. The lower the number, the thicker the gauge, which creates a firmer mattress. A 12-gauge mattress will be very firm and provide plenty of support, but if you’re looking for something a little softer go for a 13.5-gauge which still offers plenty of support.
Open coil mattresses provide excellent support and are used for most orthopaedic mattresses due to their firmness. They tend to have more give than pocket sprung mattresses, and are lighter and therefore easier to turn. Investing in an open coil mattress with an inbuilt memory foam topper will give a superior level of extra comfort.
