Open coil (also known as Miracoil, Continuous coil, Standard coil e.t.c) are the most common types of mattresses, which consist of an inter-connected spring system. Open coil mattresses are the very worst of all spring units in mattress showrooms. They are the traditional manufacturing method for mattresses, capable of being mass-produced with a low production cost – this makes them one of the cheapest on the market.
Many open coil systems use hour glass shaped springs in their interconnected systems so that the evenness is distributed from the top to bottom.
Pros: Durable materials and traditional even feel. Open coils 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.
Cons: Pressure point discomfort and motion transfer issues. Not as robust as other mattresses and can be known to ‘dip’ in the middle after prolonged use. Open coiled bedding can also lead to the ‘roll-together’ feeling for couples, and you will feel the movement of your partner.
