Notable Open Coil Mattresses
Open coil mattresses remain one of the most enduring and popular bedding product choices today. An inexpensive option, coil sprung interior mattresses are used widely by bed manufacturers throughout the world with the most widely used type Bonnell spring still a winner today.
Open coil spring mattresses are constructed from springs that have been arranged in rows connected to each other via a spiral helical wire. Strengthened and held in tension through an outer perimeter rod, this process helps the mattress retain its shape and is extremely durable.
The number of springs used in an open coil mattress varies, but a typical 5’ bed contains in the region of 325; more for higher quality models. The level of support and tension offered by a coil spring mattress is dependent on the gauge (thickness) of the wire with a 12.5g providing firm support - the higher the gauge, the softer the tension.
King Koil’s commitment to ongoing research and development in back care has led to the production of a range of unique open coil spring construction mattresses. The King Koil Spinal Visco 5' Mattress provides great support for the back and spine and has been fully endorsed by the International Chiropractors Association.
Similar to the open coil spring is the continuous spring mattress. Incorporating smaller coils and with lighter gauge wires, these mattresses are usually formed from a single length of wire and the bed springs are linked vertically as opposed to horizontally. Considered an entry level mattress, open coil and continuous springs are a good, affordable option for anyone on a budget.
