How we test our mattresses


The science behind Sealy

We strive to ensure that your mattress is rigorously tested and designed to last, and that your Sealy product looks and feels the same on day 365 as it does on day 1.


What do we measure?

Every Sealy mattress is built to specific criteria set by the Orthopaedic Advisory Board. We measure our construction methods, designs and prototypes to ensure they offer correct support and optimal comfort in line with these requirements.

We also conduct quality assessments on our components and materials. We strive to produce mattresses that deliver exceptional performance for years to come. The intersection of comfort, support and durability is the foundation of our Posturepedic criteria and it is what makes our mattresses unique.

The importance of Research and Development

We are proud to have a unique and diverse team in Research and Development with extensive technical knowledge and industry experience. Hailing from varied disciplines, the team includes designers, engineers, scientists, project managers, mechanical specialists, upholsterers and more.

From ensuring that the comfort of each mattress is as exceptional as possible, to testing the sturdiness of the mattress edge or the durability of the mattress itself, our Research and Development team strive for nothing less than perfection.

With the only accredited mattress test lab in Australasia, we take Research and Development seriously. We are constantly working on developing better beds to help people all over the world get a better night’s sleep.


Comfort layers

Your Sealy mattress is designed to cushion your pressure points and minimise any impact on your body. We use this research to develop mattresses with optimal comfort layers for deep, refreshing sleep.


This test is performed by lowering a manikin onto a sensor mat. Using specialist software, we measure the performance of the mattress in terms of pressure distribution.

Essentially, we are able to see whether it has sufficient cushioning. If the amount of pressure is too high, it indicates that the mattress is not offering appropriate comfort.


Our Cornell device presses into the mattress with 102kg of force 100,000 times. This test is the equivalent of someone sitting in the same spot over and over again.

We do this to see how the materials stand up to continual pressure. The height and comfort of the mattress should not be compromised beyond an acceptable amount, even after years of use.


We use weighted rollers to measure the amount of disturbance caused by a partner shifting or moving during the night.

This allows us to assess our mattresses against real-world interactions and consumer needs. We take this information and create solutions with improved performance, designing beds for minimised disturbance and improved rest.


Support systems

We test our support technology to ensure it promotes correct spinal alignment. In addition, we ensure our comfort layers, construction methods and designs work in harmony with our coils to offer correct support.


Our rollator barrel moves across a mattress 200,000 times in a single test. Weighing 110kg, it helps us to understand the impact of a person shifting and moving on a mattress. Additional fatiguing occurs with the hexagonal shape

Once the test is complete, we measure changes in the structure and height of the mattress. In order to pass, the mattress must meet certain criteria so that we know it can withstand 10 years of use.


Sealy mattresses are designed and built to specific criteria. We know from our research with orthopaedic surgeons that the best sleeping posture is the same as when we are standing upright.

We use ‘spinal alignment manikins’, to simulate the way a human body interacts with a mattress. We measure the angles of their bodies as they lie down and assess the mattress against strict support requirements.


One of our robots is specially designed to sit on the edge of a mattress and ‘hop into bed’. It slides across the surface of the mattress the same way most people do at home, applying constant pressure.

This process is repeated 5,000 times before we check for any changes in height or feel and assess internal components. It allows us to understand how the mattress will perform in the home for a decade of typical use.


Quality and durability

We conduct testing on every component and material that goes into a mattress, including panel fabrics, handles, comfort layers, edge supports and springs.


We measure the performance of our foams in a number of tests to get an understanding of their firmness and overall quality.

We do this to ensure that our foams offer the right amount of comfort and durability. We also check for any foreign additives in the foam that could compromise its integrity, striving for material consistency.


One of our fabric tests involves taking samples and running them in a cork drum for 90 minutes. The drum creates surface fussing and rubbing.

We assess the samples afterwards for pilling or tears. The textiles we use need to withstand expected stresses during manufacturing, moving, and years of use in the home without compromising on quality.


This machine runs for 10,000 cycles, repeatedly rubbing a fabric sample across an abrasive surface. It is designed to simulate years of wear and tear.

Once the test is complete, we check for any ripping, pilling or deterioration. We do this to ensure that our panel fabrics are smooth and pristine for the full life of the mattress.
