Open Coil Mattresses

Open coil mattresses use interconnected springs that work together as one unit, whilst pocket spring mattresses have individual springs in fabric pockets. Open coil systems provide a bouncier feel with good support, though they transfer movement more than pocket springs. They're also more affordable and offer excellent ventilation, making them suitable for smaller spaces like motorhomes.

Open coil mattresses typically offer medium to firm support depending on the spring gauge and comfort layers. The interconnected spring system provides consistent support across the surface. Comfort can be adjusted through different foam layers on top of the springs. Most people find them supportive enough for regular use while maintaining good spinal alignment.

Custom open coil mattresses can be made in thicknesses from 100mm to 200mm. Thinner options work well in spaces with limited headroom, whilst thicker mattresses provide more comfort layers. The spring unit itself requires a minimum depth, so very thin mattresses may use alternative constructions. Most customers choose between 125mm and 150mm for the best balance.

Open coil mattresses offer excellent ventilation due to the spring construction and gaps between coils. This makes them suitable for potentially damp environments like boats or caravans. The airflow helps prevent moisture buildup and reduces the risk of mould. However, proper ventilation in the sleeping area and a breathable base are still important.

Lead times for custom open coil mattresses typically range from 7-14 working days depending on current production capacity and seasonal demand. Each mattress is made to order using exact measurements provided. Free UK delivery is included, with the mattress arriving vacuum-packed for easy handling. Delivery times may extend slightly during peak periods.

Custom open coil mattresses come with guarantees up to 10 years depending on the specific construction and materials used. The guarantee covers manufacturing defects and premature sagging of the spring system. All mattresses include BS 7177 fire safety certification as standard, which is required for motorhome and caravan insurance compliance.

Custom open coil mattresses can be cut to most irregular shapes including curved corners, cut-out sections, and angled edges. The spring unit may need modification for complex shapes, which could affect the support in certain areas. Simple modifications like rounded corners or small cut-outs work well without compromising the mattress structure significantly.
