Mattress and Divan Springs
The construction of mattress and divan springs falls into two categories. i.e. (i) an open coil construction, and (ii) a pocketed construction. We, at Burgess, use both systems in order to meet the needs and the requirements of each and every customer new and old. The object of this section is to briefly describe the basic construction of each type.
Open Coil Spring Construction
The open coil type of mattress spring is the type usually marketed by volume producers. The first photograph below shows individual open coil springs prior to assembly. The left hand coil (5 coils) is the type used in all Burgess open coil mattresses with the exception of the Kensington, which uses the right hand coil (6 coil). Each individual coil is laced together, lengthways and widthways, by a wire screw known as a helical wire. The second photograph shows this, the helical wire running across the width of the mattress. Because of its construction, open coil mattresses tend to only have 50% maximum of the springs assembled into a pocketed mattress. All Burgess divans/bases utilise an open coil spring construction.
Pocketed Spring Construction
The benefits of the pocketed type of mattress spring construction, versus the open coil construction, are many and varied e.g:
- At least double the amount of coils are used in the pocketed type. For example, the Lancaster mattress uses 960 pocketed springs in the 5'0 size versus 430 open coil springs in the Buckingham mattress.
- Pocketed type construction minimises roll together. The first photograph shows an individual coil before being compression assembled into its individual white calico pocket. Each pocket is hand nested and sewn together at the centre of each spring therefore effectively isolating each spring's deflection from each other. See second photograph below.
- The density of spring count achieved in a nested, pocketed construction is clearly demonstrated in photograph five.
- Because more individual coil springs are used in the pocketed construction then common sense suggests that the user will enjoy a better support. Each individual spring can be very light yet the whole assembled spring will be very supportive. Further, as can be seen in photograph three, Burgess only use 6coil, barrel shaped pocketed springs in their traditional pocketed mattresses. This ensures the full recovery of the spring after compression.
