Free Delivery Open Coil Mattresses
Open coil mattresses remain one of the most popular and reliable mattress types, offering good all-round support at an affordable price. Using a continuous spring system, often based on the traditional Bonnell spring design, open coil mattresses provide consistent support across the sleeping surface.
The level of comfort and firmness depends on the gauge of the wire used, with lower gauges offering firmer support and higher gauges providing a softer feel. Open coil mattresses are a practical choice for a wide range of uses, from children’s bedrooms through to guest rooms and everyday sleeping. If you’re unsure whether an open coil mattress is right for you, our Mattress Buying Guide explains the differences between spring systems and comfort levels.
Available in sizes from single through to double, king and super king, our range includes open coil mattresses from trusted brands such as Respa, Slumbernight and King Koil.
