Mattress Glossary of Terms

This list is arranged in alphabetical order


Pragma Bed Pragmatic Adjustable Bed Frame

Adjustable Bed Frame: Commonly referred as adjustable base, this allows you to customize and adjust your mattress so you can easily move to different angles and find the most comfortable sweet spot or sleeping position that will help you sleep optimally.

Antimicrobial: This is treatment applied onto the fabric material of the mattress to help prevent and get rid of pathogens, microorganism, and dust mites that could wreak havoc and pose health risks.

Avena Foam: This is a patented foam which is 100% recyclable and said to have the same support, bounce, responsiveness, and comfort with latex but with a longer lifespan than the latter.


Batting: This pertains to the wool, cotton, or synthetic fiber and material inserted in sheets or batts which are used as filling for bed covers and quilts.

Body Impression: The indentations a body makes on a mattress over time. Impressions do not bounce back after a sleeper is off of the mattress. Body impressions should not be deeper than 1 1/2 inches.

Border Wires: Also referred to as border rods, this is mostly used to support the innerspring coils and helps your bed or mattress to maintain and retain its original shape over the years.

Box Spring Bed Frame

Bounce: This refers to the amount of push-back or responsiveness a mattress has when it interacts with body or how it pushes back on pressure. Mattresses with a high degree of bounce, such as coil models, strongly transfer energy back. Models with low bounce, like memory foam mattresses, absorb energy rather than pushing back.

Box springs: This is a framed bed base that consists of vertical steel springs covered with cloth which is usually placed under the mattresses to provide support. Some beds require the use of box springs except daybeds or bunk beds. This acts as the base and is usually the same size as the mattress.

Bunkie Board: This refers to a thin plywood or board tapered with light upholstery which is typically used as a platform to elevate the bed. It is also a popular alternative to using thicker box springs. Also spelled as “bunky board”, this is commonly used in platform beds that can fit all bed sizes from King, Queen, to Twin-sized.


Coil: This refers to the steel wire springs found under the mattress which provide support and even distribution of body weight. This provides the bounce, resistance, and push-back when your body touches its surface. Coil count varies from one brand to another. It is important to note that coil count does not equate with having superior quality mattresses. Each manufacturer has different standards when it comes to coil count.

Comfort: How hard or soft a specific model feels when you touch its surface. This is an objective term and can also include overall comfort including firmness, conformability, support, and motion separation.

Contoured Mattress: This type provides the contour or conforms to the curves of your body. Its thick cores provide relief of pressure points and gels with the movement of your body as it becomes soft at the areas that you need it and firm exactly where you want it.

This refers to a wire support system or foam padding which is placed on the border to provide extensive edge support. You can determine if your mattress has a built-in edge guard by sitting at its edge. Check if it holds its shape or gets saggy. If it holds its firm shape, then it definitely has an edge guard in it.

Edge Support: The degree to which a mattress supports lying or sitting on the edge. Mattresses with poor edge support will sink down when sitting on the edge or cause you to “roll off” the edges if they collapse under your weight. Some all foam mattresses or those using cheaper or less dense foam will have poor edge support.

Euro-style Pillow Top – If you want it tall and extra plush, then this should be your top pick. This is similar to the traditional pillow top in terms of the softness and durability. A Euro-style pillow top provides sleepers an extra thin layer soft material which is stuffed right under the top cover of the mattress. What differentiates this from the traditional pillow top model is that it has a secondary casing stitched on top. Euro-style pillow toppers usually include the cover with pillow stuffing which provides both the comfort and aesthetic boost you need in a topper.


Firmness: The softness or hardness of a mattress when you touch it. It pertains to the overall feel of the mattress under your body. Firmness is an important factor in choosing the right model. Note that firmness and support are not the same, as support refers to how well a mattress keeps your spine aligned whether you’re on a soft or firm model.


Foundation: This pertains to the bed base or supportive structure found under a mattress. This may particularly refer to box spring, slatted base, platform, or another type of foundation.

This aims to maximize the benefits of these varied materials combined and also to reduce its negative effects.

Plush Top: If you want something medium or in between the pillow top and firm mattress then this is the perfect fit. It has a very supportive base and a soft and comfortable top which provides that good balance needed for slack time.

Pressure points: Parts of the body where pressure from a sleeping surface restricts blood flow. This is usually felt when the mattress is too soft or lacks firmness and support. Further, this can cause discomfort, pain, and trouble sleeping.


Queen Size: A mattress that measures 80″ x 60″ usually.


Recovery Time: The amount of time foam takes to recover back to its original shape after compression.

Responsiveness: The speed with which a mattress adjusts to pressure changes, typically in foam mattresses.

Newer memory foams typically have better responsiveness than older ones. This is also known as resiliency.


Talalay Latex – Talalay is hypoallergenic, hygienic, breathable, and provides even cushioning. This also features more consistent support and feel from top to bottom. This flash-frozen latex is usually baked which completes its manufacturing process. It provides a good amount of hug and responsiveness.

Support: Spine alignment is one of the factors or quality that you need to look out for when shopping for mattresses.

Support Foam – This is a basic type of foam that is mostly used as the base or foundation. This is also used in the construction of some hybrid mattresses.
