Free Delivery Open Coil Mattresses
Open coil mattresses are among today’s most enduring and popular mattress types. An inexpensive option, coil-sprung interior mattresses are widely used by bed manufacturers. The most commonly used type, Bonnell Spring, is still a popular choice today.
The number of springs in an open coil mattress varies, but a typical 5′ mattress contains around 325, more for higher-quality models. The level of support and tension offered by a coil spring mattress depends on the gauge (thickness) of the wire, with a 12.5g providing firm support – the higher the gauge, the softer the tension.
A single open-coil mattress is ideal for children’s rooms, and it can be sized up to a double, king, or super king-size model.
