One of the most enduring and popular bedding product choices today is the small single open spring mattress. A relatively inexpensive option, these mattresses are constructed from springs that have been arranged in rows connected to each other via a spiral helical wire.
Strengthened and held in tension through an outer perimeter rod, this process helps the mattress retain its shape and makes for an extremely durable design.
The number of springs used in an 2' 6" open coil mattress varies, as does its gauge (thickness) - a typical 12.5g provides firm support - the higher the gauge, the softer the tension.
Incorporating smaller coils and with lighter gauge wires, small single continuous spring mattresses are usually formed from a single length of wire linked vertically as opposed to horizontally. Considered an entry level mattress, open coil and continuous spring small single mattresses are a good, affordable option for anyone on a budget.
