A popular choice for both children and adutls, a small double open spring mattress is an inexpensive mattress option.
Constructed from springs that have been arranged in rows connected to each other via a spiral helical wire, a 4' open coil mattress is strengthened and held in tension through an outer perimeter rod. Helping the mattress retain its shape, this process makes for an extremely durable design.
Although the number of springs used in an open small double 4' mattress will vary, its tension will differ depending on its gauge or thickness) with a typical 12.5g mattress providing firmer support. The Sweet Dreams Minstrel 4' Mattress is a great value entry level mattress incorporating a 13.5 Gauge Open Coil Spring Unit with a deep quilted Damask cover and layers of quality fibre fillings.
Somewhat different in its make-up, a small double continuous spring mattress has smaller coils and lighter gauge wires. Formed from a single length of wire, the mattress springs are linked vertically as opposed to horizontally.
The Sweet Dreams Concerto 4' Mattress combines a traditional open coil spring unit with fibre fillings to provide a medium feel. Finished with a micro-quilted top with a Damask cover this quality mattress represents excellent value for money.
