The Ergoflex 5G Memory Foam has a medium-firm feel, making it suitable for back-pain, back-sleepers.
It uses memory foam construction to provide:
Ergoflex has been Australia's go-to for back pain sufferers since 2010. The 5G is a dense, firm memory foam mattress engineered for spinal alignment and pressure relief.
The firmer feel keeps your spine properly aligned — particularly beneficial for back and stomach sleepers. The dense memory foam contours to your body without the sinkage that can exacerbate lower back pain.
If back pain is your primary concern, Ergoflex is the specialist pick. Not the most luxurious mattress, but one of the most purposeful in the Australian market.
The Ergoflex 5G Memory Foam delivers consistent, reliable comfort for most Australian sleepers. The medium-firm feel suits the widest range of positions and body types.
Support is the most important factor when choosing a mattress — more important than comfort, price, or brand name. A mattress that fails at spinal alignment will cause morning stiffness and back pain regardless of how comfortable it feels in the short term.
The Ergoflex 5G Memory Foam performs well in this area by:
It's particularly beneficial for back-pain and back-sleepers.
One important note: spinal alignment also depends on pillow height and bed base quality. A foam mattress on slats wider than 7cm will undermine even the best mattress. Ensure your base is appropriate before attributing any alignment issues to the mattress itself.
If you sleep hot — and in Australia's climate, many people do — cooling is a non-negotiable factor. We weight temperature regulation at 20% of our overall score, higher than most US-based review sites, because Australian summers genuinely demand it.
As a memory foam mattress, the Ergoflex 5G Memory Foam uses open-cell foam construction to improve breathability compared to traditional dense memory foam. This helps reduce heat buildup, though it won't match the airflow of a hybrid mattress with a pocket spring base.
For very hot sleepers in Queensland or WA, pairing with linen or bamboo bedding will significantly improve overnight temperatures regardless of the mattress chosen.
The Ergoflex 5G Memory Foam is constructed using a memory foam system designed for long-term durability in the Australian market. The material stack is:
These materials are CertiPUR-US certified (or equivalent), meaning they've been tested for harmful chemicals including formaldehyde, heavy metals, and VOCs. The cover is typically a knitted fabric designed for breathability and stretch.
In terms of durability, a well-maintained Ergoflex 5G Memory Foam should last 7–10 years under normal usage. Using a quality mattress protector from day one significantly extends this lifespan by preventing moisture and debris from reaching the foam layers.
In Australia, the Ergoflex 5G Memory Foam is priced at approximately $1,395 AUD for a Queen. This sits in the mid-range tier of the Australian mattress market.
Compared to similar mattresses at this price point, it offers:
Ergoflex regularly runs promotional discounts of 15–30% during major Australian sale events. Checking our deals page before purchasing can save you $150–$400.

A new mattress works best with the right accessories. These are the three things most people buy alongside a new Ergoflex — all available on Amazon.com.au with fast delivery.
Required to keep your 7-year warranty valid. Most brands void warranties for stained mattresses.
The right pillow height completes your spinal alignment — a good mattress with a bad pillow still causes neck pain.
Foam mattresses need slats under 7cm apart. A wrong base causes premature sagging and voids warranty.
The Ergoflex 5G Memory Foam is a solid mid-range choice for Australians looking for a balance of comfort, support, and affordability. The medium-firm firmness suits the widest range of sleepers, and the 100-night free trial removes most of the purchase risk.
Where it excels: pressure relief and motion isolation — particularly strong for side sleepers and couples. Where it's less ideal: sleeps warmer than foam alternatives.
For most Australian sleepers, it's a reliable, well-made mattress that delivers what it promises. The 7-year warranty and generous trial make it a low-risk purchase.
