Comfort, Support & Durability Expanded

The extra upholstery layers in today’s bedding are designed to enhance the comfort of your sleep set. You may find any combination of the following materials in modern sleep sets:

Comfort Layers - The layers of material in a mattress that provide the comfortable surface feel, usually multiple layers of foam and synthetic fibers

Convoluted Foam - Egg crate shaped (hills and valleys) this foam is used most in plush or pillow top models to provide comfort. Designed for hospital use it helps reduce pressure points and can allow for better circulation or blood flow.

Latex- A natural foam product made from a rubber tree often used in ultra premium sleep sets.

Memory (Visco) Foam - A Visco Elastic foam that will resist impressions and is temperature sensitive

Today’s innerspring units are designed to provide more support than ever before. Here are a few of the innovative designs of today:

Bonnell Coil - Designed with an hourglass shape, this coil’s largest diameter is at the top and bottom of the coil and tapers towards the center. Common innerspring units using the Bonnell coils are 252,312, and 364 full size units

Continuous Coil - These are entire rows of coils made from a single wire running head to toe or side to side

Helical - Wire spirals used to hold together rows of coils or attach innersprings to the border rod.

Marshall Coil - A type of innerspring made of individual coils encased in a synthetic fiber or pockets then attached to a perimeter border wire.

Off Set Coil - Similar in shape to the Bonnell coil but there is a squared off section at the top and bottom to prevent turning. Some manufactures use double or triple off set coil designs.

Most sleep sets are designed to work with a particular style box spring or foundationon. A proper foundation or boxspring will properly support your mattress and improve the overall durability of your sleep set

Foundation Box (European Foundation) - This is simply a wooden and press board box it looks like any box springs but contains no steel. This type of foundation is typically used on all Foam products or value priced bedding.

Semi Flex (Limited Deflection) Boxspring - This style of foundation is the wood frame with rigid steel supports. While it contains steel the components do not flex in any meaningful way. You will typically find this non-working style foundation used with a Pocketed coil inner spring unit or on beginning level master bedroom sets.

Working (True) Boxspring - This type of foundation consist of the wood or steel frame work = to absorb impact and reduce wear and tear on the innerspring unit. You most often find working box springs on better quality sleep sets.
