Bedding:

A broad term encompassing different bed-related entities like the mattress, linens and so forth; all that constitute a bed.

Body Impressions:

Refer to wearing and settling of upholstery layers in a mattress. These are normal and expected to dissipate over time.

Bonnell Coil:

An innerspring mattress coil with rounded hourglass shape. Such individual coils are held together with metal strings, referred as helical lacing.

Border Wire:

It is a strong wire used in connecting the coils constituting the perimeter of a mattress to offer greater edge stability.

Box Spring:

Also referred as the foundation, it is a unit hosting springs or metal rods supporting the mattress.
C

Coil:

Supportive springs that constitute the foundation of an innerspring mattress, part of a system meant to provide support to the mattress.

Coil Count:

Refers to the total number of spring coils used in the base of a mattress.

Coil Gauge:

A term used for the measure of total thickness of coils used in a particular mattress.

Coil Configuration:

The specific way coils are arranged in a mattress.

Comfort:

A way of describing how a mattress feels, taking into consideration how well the cushioning materials conform to an individual’s body shape.

Continuous Coil:

A coil system in an innerspring mattress that uses only one piece of wire throughout its base.

Convoluted:

A foam configuration style that features peaks and valleys.

Density:

Density gives you a count of per cubic foot weight of the foam. It is a significant element in determining the overall quality of foam. Usually, higher density in foam is interpreted as its greater durability.
D

Dust Mites:

These are tiny microscopic creatures found living in a mattress and take dead skin cells as their food. About a million of them are estimated to be hosted by a mattress and are held responsible for triggering asthma and allergies.

Double Bed:

A mattress sized 135cm x 190cm, also referred to as full size.
E

Edge Support:

It refers to a border rod as well as foam encasement meant to deliver extra support and stability to a mattress around its perimeter, contributing in its uniform comfort.

Egyptian Cotton:

Finest quality cotton that is woven with longest and softest, yet strongest fibres to produce the most luxurious fabric with lavish feeling.

Euro Top:

Extra layer of top padding on a mattress for additional softness. These tops can be compared to pillow tops, except for the fact that they are sewn to be a part of the mattress.
F

Firmness:

Firmness of a mattress describes the amount of resistance offered by a mattress to the body weight applied on it and how much it is pressed down as a result.

Foam:

Foam is to be described as a material made out of polyurethane or latex. It offers various comfort levels ranging between cloudy soft to rock hard.

Footboard:

A panel or board connected to a bed frame at its foot end.

Foundation:

It is a unit hosting springs or metal rods supporting the mattress.

Full Size:

A mattress sized 135cm x 190cm, also referred to as full size.
G

Gusset:

The squared off edges of a comforter, pillow or even an upholstery layer. Meant to add strength and also give shape to the corners and edges of such items.
H

Hand:

The feel a material gives you as the hand lightly rubs over its surface.

Hardness:

A means to determine the foam’s ability of supporting load. If foam is too soft, it will be flattened out and if it is too firm, its ability to contour is compromised.

Heat Tempering:

A process whereby the coils get heated electrically to impart them with a permanent memory. This enables coils to regain their original height even after various compressions.

Headboard:

A panel or board fitted on head end of a bed frame.

Helical:

A spiral shaped small durable wire that is used for connecting coils constituting an innerspring unit.

High Density (HD) Foam:

Foam significantly high in density and durability.

High Resilience (HR) Foam:

High quality foam able to deliver superior comfort, durability and resilience.

Hybrid Mattress:

A mattress manufactured by combination of foam as well as innerspring support technology to deliver the users with combined benefits of foam and innerspring mattress.

Hypoallergenic:

Objects and materials that do not contribute in provoking an allergic reaction are referred as hypoallergenic.
I

ILD (Indention Load Deflection):

ILD gives you the measurement of the amount of weight required to get a particular sample of foam compressed to a certain degree from its original height or thickness (e.g. 25% ILD or 75% ILD).

Innerspring Mattress:

A type of mattress featuring metal coils as its primary support system.

Independent Coils:

Coils capable of working independently of each other, resulting in limited disturbance and transfer of motion when a mattress hosts multiple sleepers.
K

King Size:

A mattress sized 160cm x 200cm.
L

Latex Foam:

Foam manufactured from natural material, offering high levels of support, resilience and durability in addition to antimicrobial and antiallergenic properties.
M

Memory Foam:

A polyurethane foam with visco-elastic properties (i.e. both elastic and viscous properties), making it an ideal solution for comfort and support in furniture products, especially mattresses.

Motion Separation:

Limiting the feeling of motion from one end of the mattress to the other.
N

Natural Fibres:

Fibres obtained from natural sources like plants and animals; for example, cotton, silk, wool and bamboo.
O

Offset Coil:

A type of metal coil used in innerspring mattresses with squared edges in order to offer enhanced flexibility and body contouring features.

Open Coil:

An innerspring mattress coil with rounded hourglass shape. Such individual coils are held together with metal strings, referred as helical lacing.

Open Cell Structure:

A permeable structure present in flexible foams where hindrance free air passage is provided through the cell windows having no obstructions. Such arrangement enables a mattress to regulate body temperature conveniently.
P

Pillow Protector:

A cover that protects a pillow from dirt, stains, moisture and so forth.

Pillow Top:

An additional layer of comfort padding over mattress surface offering softer feel without compromising its support mechanism.

Plush Top:

Just like a pillow top in feeling, but the layers of additional padding are less visible because they are sewn into the surface rather than being layered up on top surface.

Pocketed Coils:

Flexible coils with high carbon content enclosed in individual fabric pockets offering enhanced pressure relief, also blocking motion transfer between sleeping partners.

Polyurethane Foam:

An artificial material high in flexibility, durability and resilience, mostly used for the purpose of cushioning. With the exception of natural latex foam, all other types of mattress foams can be referred as polyurethane foams.

Pressure Points:

Regions of the body most vulnerable to pressure and weight when lying on a mattress. Without appropriate contouring support, these pressure points are likely to bear numbness and discomfort.

S

Sleep Set:

A generic term mostly used for describing a combination of a foundation and mattress.

Support:

A generic term mostly used in describing how a mattress handles weight distribution and stability, while contributing in maintaining appropriate body alignment.
