What is the Ergoflex® 5G Memory Foam Mattress?

The Ergoflex® 5G Memory Foam Mattress is a premium, medium-firm memory foam mattress designed to provide consistent support, pressure relief, and healthy spinal alignment. Our mattress is made using high-density visco-elastic memory foam layered over a breathable Cool-Sleep™ airflow system to assist with temperature regulation, and a supportive foam base designed for durability and long-term comfort. It’s finished with a premium TENCEL® cover, chosen for its breathability and moisture-wicking properties to help create a cooler, more comfortable sleeping environment. Each layer works together to deliver balanced comfort, support and durability.

What firmness is the Ergoflex 5G Memory Foam Mattress?

The Ergoflex 5G Memory Foam Mattress is best described as medium-firm, offering a balance of comfort and support that suits a wide range of sleepers. Its high-density memory foam gently contours to your body to help relieve pressure points, while the supportive base layer helps promote healthy spinal alignment and prevents excessive sinking. This combination makes it suitable for back sleepers, side sleepers, and combination sleepers alike. The result is a mattress that feels comfortably cushioned on the surface while providing the underlying support needed for long-term comfort and restorative sleep.

Is the Ergoflex 5G mattress good for back pain?

Yes. The Ergoflex mattress is designed to support proper spinal alignment and reduce pressure points, which can help minimise discomfort associated with back pain. Ergoflex is frequently rated by Australian customers as one of the best mattresses for back pain, reflecting our long-standing reputation for comfort and support. Learn more in our Back Pain Mattress Guide.

Does the Ergoflex mattress sleep cool in the Australian climate?

With some memory foam, latex and foam mattresses, there’s a small chance some sleepers may feel slightly warmer due to the way these materials gently contour to the body. This close-contact support is what allows for excellent comfort, pressure relief and spinal alignment. Our mattress is designed with the Australian climate in mind. Its Cool-Sleep™ airflow system, combined with a breathable, moisture-wicking TENCEL® cover, helps promote ventilation and regulate temperature for a more comfortable night’s sleep.

Is the Ergoflex mattress suitable for allergy sufferers?

Yes. The Ergoflex mattress is naturally hypoallergenic and resistant to common allergens such as dust mites. Its foam construction and breathable materials make it a suitable choice for allergy-sensitive sleepers seeking a cleaner sleep environment.

Can the Ergoflex mattress be used with adjustable beds?

Yes. The Ergoflex 5G mattress is fully compatible with adjustable bed bases. Its all-foam design allows it to flex and contour smoothly with adjustable movements without compromising comfort, support, or structural integrity.

Does Ergoflex offer a risk-free sleep trial?

Yes. We offer a 30-night risk-free home trial, allowing you to sleep on the mattress in your own home before making a final decision. This ensures you have time to properly adjust to the feel of the mattress. Returns are free from most metropolitan areas, including major capital cities and the NSW Central Coast. Learn more about how the 30-night trial works.

What happens if the mattress isn’t right for me?

If the Ergoflex mattress isn’t right for you after giving it time to adjust, you can return it under our 30-night risk free home trial . If you’re located in most metropolitan areas, including major capital cities and the NSW Central Coast, returns are free. For some regional locations, return arrangements may differ, and our customer care team will guide you through the process. Once the return is approved and collected, a refund is issued promptly. Our goal is to make the process simple, transparent, and stress free.

Ergoflex is an online mattress brand known for its orthopaedic memory foam mattress that gently moulds to your body, providing long-term comfort, support, and durability. We pioneered the mattress-in-a-box concept and have spent more than a decade refining a single mattress design comparable to premium memory foam brands such as Tempur®. Our focus has always been on proper spinal alignment, pressure relief, and consistent performance night after night. We are well known across Australia for helping people with back and joint discomfort sleep more comfortably, as well as for delivering reliable customer service and a simple, transparent buying experience.

How long has Ergoflex been in Australia?

Ergoflex has been in Australia since 2010, after first establishing the brand in the UK. At the time, high-quality memory foam mattresses were largely limited to expensive, in-store brands such as Tempur®, and buying a mattress online, let alone one delivered in a box, was unheard of. We entered the Australian market to change that. By introducing a premium memory foam mattress sold directly to customers, we helped make the comfort and support of memory foam accessible to a much wider audience. This approach played a key role in shaping the online mattress category in Australia as it is known today. More than a decade on, Ergoflex remains one of the longest-established memory foam mattress brands in the country, trusted by Australians seeking long-term comfort, support, and relief from back and joint discomfort.

Why is Ergoflex considered a trusted mattress brand in Australia?

Ergoflex is one of Australia’s longest-established memory foam mattress brands, having been available locally for well over a decade. During this time, our mattress has consistently appeared in comparisons of Australia’s leading memory foam mattresses, reflecting our stable design philosophy, use of high-density materials, and focus on long-term support. Ergoflex is particularly well regarded by customers seeking durability and reliable back support and is commonly chosen by people experiencing back pain or pressure-related discomfort. Our reputation has been built through years of proven performance, customer satisfaction, and consistency, rather than frequent redesigns or short-lived trends seen with many newer boxed mattress brands.

How does Ergoflex compare to Tempur® mattresses?

The Ergoflex mattress is often compared to Tempur® because both brands use high-density visco-elastic memory foam designed for pressure relief and spinal support. The key difference is that Ergoflex® offers this premium sleep experience in a single, carefully engineered mattress at a more accessible price point. The Ergoflex® 5G Memory Foam Mattress delivers a medium-firm feel that suits a wider range of sleepers, while maintaining excellent durability, comfort and support. With a 30-night trial and straightforward online delivery, many customers see Ergoflex® as a practical, high-value alternative to higher-priced memory foam mattress brands.
