Open coil sprung mattresses have a spring unit that is completely connected together. They tend to have more 'give' than pocket sprung mattresses, they are lighter and therefore easier to turn. They are a cost efficient solution to a sprung mattress that typically come in two tensions - 12.5 gauge or 13.5 gauge, with the former having used a thicker wire for the springs resulting in a firmer tension which is ideal for heavier individuals looking for greater levels of support.
