What’s In A Boxspring?

In a home installation of a new mattress, most circumstances require it include an underlying supporting foundation, either of a boxspring or a platform design.  Many ask why?  Or, is this extra item necessary for the use and wear of a new mattress?

The answers are provided for the most practical of concerns:

1. Most conventional bedroom furniture is of a certain height and configuration where a mattress is fitted to the installation and brought to the required level by an underpinning provided by a boxspring and/or platform foundation.

2. There are different types and profiles (heights) of boxspring and foundations that can meet these requirements.  Traditional boxsprings can be visualized as a ribbed and supported wooden framework to which a metal wire shock absorber is attached and fully upholstered with a variety of padding and covered with a fabric casing. Platform foundations, sometimes referred to as posture bases may have a similar ribbed bases frame to which a solid box enclosure is attached creating a depth that can be as little as 2 inches or as high as 8 or more inches, also upholstered and finished with a fabric casing to match with the mattress it supports.  Contemporary boxsprings and foundations today are often minimally finished with little padding or materials when compared to a mattress.

3. There are different type of boxsprings:

– 10%-15% with pocketed spring design that offers luxurious flex underpinning

– 10%-12% with web-and-coil single cone shaped coils that offer luxurious flex underpinning

– 10% deflection with single cone shaped coils that offer luxurious flex underpinning

– 10% deflection with double-cone shaped coils, also called coil-on-coil, that offers luxurious flex underpinning

– 5% deflection with individual modular-firm coils that offers firm-flex underpinning

– zero deflection single unit wire grid that offers very firm-flex underpinning

4. In all cases, boxsprings and foundations are, by original intent, designed to perform as shock absorbers for the supported mattress. When used correctly, each can add a distinct comfort and support characteristic to the way the mattress is felt by the user.

5. The only cautionary note is not to re-use and old boxspring, foundation or other support system with a new mattress as its previous use will have imposed a wear pattern that is inappropriate to support a new mattress.  It would be expected to damage the new installation and void the mattress warranty.

Marshall Mattress views its boxspring and foundation styles as integral to producing its fine sleep sets.  Consequently significant attention is given to how each type is finished and used to enhance and complement the supported Marshall mattress design.
