Mattress Guide

Mattress shopping really is simple. What should you look for in a mattress? 

Three things: comfort, support, durability provided by a brand you trust.

It's that simple.

Anchor 1



Comfort, how the mattress feels, is a matter of personal preference. What feels comfortable to one person may feel uncomfortable to another person. Therefore, whoever is going to use the bed should try several different models before making a purchase.


Surface comfort is determined by the upholstery of the bed. Upholstery refers to the various layers of material between your body and the innerspring. Both the type and thickness of these materials will produce different levels of feel and therefore different degrees of comfort.


So you'll need to determine your comfort preference. Sealy Posturepedic mattresses are available in the following comfort levels: firm, cushion firm, plush and ultra plush. It's important to note that all Sealy Posturepedic sleep systems offer correct back support regardless of firmness.


Definition of Firm: Firm mattresses offer the least surface 'give' and would be considered harder in feel than other comfort levels


Definition of Plush: Plush mattresses offer more surface 'give' and provide a softer surface comfort

Why Sealy is best in Comfort?


  • For more than half a century, Sealy scientists have been engaged in active research and development, focused on the needs of the human body at rest


  • This research and development programme has identified and defined the role of conformability (comfort) in the elimination of pressure points and has resulted in the introduction of patented comfort components such as StayTrue® fibres and foam, StayTrue® Durabond insulators and Unicased® construction


  • Sealy works closely with its upholstery suppliers to ensure only the finest quality foams, fibres, and tickings are sourced, that meet Sealy's strict standards.

Sealy sleep systems offer correct back support regardless of firmness. This is the essence of the Sealy Posturepedic heritage, formed in conjunction with orthopedic surgeons and patented in 1950. The myth 'firmer is better' is not necessarily true. Your body type determines what comfort is better for you.


A mattress that's too firm for your body will not support all parts of the body evenly, and may cause discomfort at the body's heaviest parts - the shoulders and hips. The increased pressure on these points reduces blood circulation and will cause tossing and turning. This may result in a poor night's sleep and a far less productive day.


A mattress that's too soft for your body will not keep the spine in proper alignment. This will cause your muscles to work through the night to straighten the spine, leaving you tired and aching in the morning, resulting in a less effective day.


We invite you to take the Sealy Comfort Test at your local retailer to discover the comfort and support unique to Sealy Posturepedic. The best test for proper support is to lie down on the mattress and experience its support. If you feel your body sagging, the mattress is not giving you proper support. And if you feel excessive pressure, the mattress is not giving you proper support.


Support is a function of the innerspring. The innerspring is located in the center of the mattress. The type of support it provides depends on its coil configuration and design. Our mattresses use premium quality spring steel coils that are hinged together for conformance and stability. The UniCased® Edge system prevents edge breakdown and roll-out tendencies while giving you uniform comfort and support, all the way to the edge. Solid edge support means you won't feel as though you're going to slide off the mattress when lying or sitting near the edge.

Why Sealy is best in Support?


  • Sealy's patented, industry leading Posturepedic innerspring senses an individual's body weight and responds with the appropriate support


  • Sealy manufactures its own Posturepedic innersprings to ensure that they meet our exact and high performance standards


  • Sealy uses twice-tempered spring steel so the coils will return to their original height repeatedly over time for a consistent surface feel


  • The Sealy research and development programme has identified and defined the support criteria to ensure correct skeletal alignment

No doubt you want a sleep system that is going to last; therefore, durability is very important.


The type of upholstery materials, the type of steel and the design of the innerspring impact on the durability of the mattress. For example, our coil systems are heat tempered twice, which helps maintain their shape so they last longer. Our UniCased® Edge and Base optimise the performance of the Posturepedic innerspring through its unique design, providing excellent durability.


The purpose of the Spring Foundation is to extend the life of the sleep system. It absorbs the major portion of stress and weight placed on the sleep surface. It works much like a 'shock absorber' in a car's suspension to eliminate stress in the mattress unit and prolong the mattress life.


A worn-out Spring Foundation can significantly shorten the life of a mattress. Not using a Spring Foundation with your mattress can also shorten the life of the mattress. A properly designed Spring Foundation provides strong support with some flex.

Why Sealy is best in Durability?


  • The Sealy Interlock Grid Top Foundation is specifically designed to work with the Sealy mattresses to deliver the maximum comfort life.


  • The Sealy research and development programme has identified and defined the correct durability criteria to ensure that your Sealy bed continues to deliver ‘showroom’ performance, year after year.
