Read about Open Coil Mattresses
Open coil (also known as Miracoil, Continuous coil, Standard coil e.t.c) are the most common types of mattresses, where the spring system is interconnected by wire. This has been the traditional method of manufacture for mattresses for many years. They are capable of being mass-produced with a low production cost making them one of the most cost effective mattresses on the market. A standard double open coil mattress will contain an average of 300 springs. Manufactures will refer to the ‘gauge’ of the mattress, this indicates the thickness of the wire used for the springs. The lower the gauge number, the thicker the wire used for the springs. The thicker the wire 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 but will not be as firm. A high-gauge rod edge is incorporated around the edge of the mattress which allows the mattress to be used up to the very edge Open coil mattresses provide excellent support and are used as orthopaedic mattresses due to their firmness. They tend to have more ‘give’ than pocket sprung mattresses, and are lighter and therefore easier to turn.
