Springs and material inside a Sealy Posturepedic mattress

How do Sealy Posturepedic Mattresses work?

You may be familiar with the word 'Posturepedic' – but what does this name mean and what sets it apart? 

Mattress Cross Section


Where does the word ‘Posturepedic’ come from? 

The word 'Posturepedic' is a contraction of the words posture (the position in which a person holds their body) and Orthopaedic (the medically correct position of skeletal and associated structures of the body).

Sealy Posturepedic represents the culmination of years of continuous research and the ongoing development of technology and systems provide the best level of support for your body while sleeping. When you lie on a Sealy Posturepedic mattress, it’s more than just springs, foam and fabric. 

What is a Posturepedic mattress?

A Posturepedic mattress is made with three parts in mind: support, comfort and durability. Getting the right balance of these three areas is essential.

While you might assume that every mattress is supportive, we know based on our testing that not all mattresses are created equal. The Sealy Posturepedic range has been designed upon a history of orthopedically correct support to help provide the right amount of support for your needs.

Here’s how it works:

  • The body needs to be correctly supported to allow the muscles to relax
  • Relief of pressure points minimise your body’s need to toss and turn during sleep
  • Orthopaedically correct design is the balanced combination of these two elements

From a support perspective, Sealy have invested a lot of research and development into the Open Coil Technology, which is central to the Posturepedic support system.

Different springs provide different support. The springs inside a Sealy Posturepedic mattress are what's known as inner spring coils. Made of titanium alloy, these metal springs are light but very strong and provide the deep support based on the criteria developed by the orthopaedic surgeons who designed the first Posturepedic mattress so many years ago.

Inherently, the Sealy Posturepedic support system is a transfer of motion; the mattress senses your body weight and motion  and responds with the right amount of support needed.  This customised support helps provide a better quality of sleep.

While support is provided by the infrastructure system of the mattress, this will not ensure proper posture alone.

At Sealy, we’ve developed an understanding of foam and how to build a better bed. 

In essence, mattress comfort comes from its foam layers. But building a great mattress isn’t just about stacking a bunch of foam together; you need to make sure all the layers work together in combination, in order to create the right mattress ‘feel’ ranging from ultra-plush to extra-firm and everything in-between. There are architectural principles and designs that are established to ensure all the layers work harmoniously and continue to do so over time.  

The comfort layers of a Sealy Posturepedic are made of a mixture of memory foam and gel-infused visco, which provide extra cushioning, allowing you to ‘sink into’ your mattress a bit more for a luxurious comfort feel. 

Having the right layers in place also helps dissipate pressure and relieve any soreness. For example, if you sleep on your side, there will be pressure on your hip and shoulder at the points which come in contact with the mattress. Comfort increases conformance which helps to ensure you get into an optimal sleeping position.

The last component isn’t so much about mattress functionality, but rather its longevity; while foam forms the comfort layer of the mattress, we still need to make sure that it is durable.

A common problem with mattresses is that they begin to sag and deteriorate over time, which can be detrimental to your health. Furthermore, they can simply become uncomfortable which can keep you tossing and turning at night. 

At Sealy, we do quality testing each month on a variety of components in a NATA accredited facility. 

When you select a Sealy Posturepedic mattress, you are getting a product with components which have been subjected to fatigue and wear/tear testing to ensure quality.

The Posturepedic difference

A Sealy Posturepedic mattress is one that is built strategically to help provide proper support for the entire body, the comfort of a great night’s sleep and durability - with a mattress that is guaranteed to function properly for ten years. 

Rest assured, selecting a Sealy Posturepedic will help you achieve a quality night’s sleep and wake up feeling rested and refreshed.
