Notable Sleeptight Open Spring Mattresses
One of the most widely used spring interiors, Bonnell or open coil springs are arranged in rows and connected to each other via a spiral helical wire. These are strengthened and held in tension through an outer perimeter rod which also helps to retain its shape. The number of springs used in an open coil mattress varies and the level of support offered is also dependent on the gauge (thickness) of the wire with 12.5g considered a very firm mattress.
Part of the Kellett Group, Sleeptight has been making quality and affordable mattress for over fifteen years. The Sleeptight Bronze 5' Mattress is an ideal starter mattress. Built upon the Bonnell Spring System, this model has been toughened for extra durability and is finished in a soft touch fabric for extra comfort. Similarly, the Sleeptight Regatta Mattress has an open coil interior but comes with a tufted design to hold the extra fillings together, providing a firmer feel.
For those that prefer the pressure relieving qualities of memory foam, the Sleeptight Regatta Memory 4' 6" Mattress combines Open Coil Springs with Visco Memory Foam to provide a complete sleep system. Built on a toughened open spring unit for added comfort and support, the Sleeptight Regatta Pillow-Top Mattress has an additional layer of filling on the top for added comfort.
