Why our sleep experts loved it
As a sleep specialist who's tested more mattresses than I have bedtime stories, the Ergoflex 5G caught my attention with its promise of orthopaedic support and pressure relief. It looks like a standard memory foam bed, but don’t be fooled - it’s more like a sleep laboratory in a box. I spent several nights on it, and I’m ready to give you the lowdown.
Comfort and Feel First impressions: Lying on the Ergoflex 5G is like hugging a marshmallow that refuses to let you sink too far. It feels medium-firm (around 7/10) - supportive yet yielding. The plush memory foam top (about 9cm thick) hugs your shoulders and hips, spreading out pressure as you sink in.
This means a gentle sink under heavy areas followed by firm push-back from the dense base. In practice, pressure on shoulders and hips is well relieved. It’s soft enough to cradle you but firm enough to keep your back from over-arching. The feel is just right - imagine Goldilocks’ mattress if she cared about spine support.
Support and Spinal Alignment The 5G supports your spine’s natural curve. The firm base stops your hips from dropping too low, so your back stays fairly straight. Stomach sleepers often arch on soft beds, but not here - the 5G’s support under the belly prevents sagging and keeps the spine aligned. It offers neutral support in most positions, which is great for anyone with back or joint pain.
Suitability for Different Sleep Positions The Ergoflex 5G aims to suit many sleeping styles:
Back sleepers - Usually very happy. You get solid lumbar support and shoulder cushioning, keeping your spine aligned.Stomach sleepers - Also a good match. The firm midsection support stops your hips from sinking too much, helping prevent lower back strain. You won’t need a rock-hard bed.Side sleepers - More mixed. The foam hugs shoulders and hips, so heavier side sleepers should be comfortable. Lighter side sleepers may find it a bit firm at the hips or shoulders and might wish for extra give.Combination sleepers - Pretty versatile. The foam adapts as you move and the base stays firm, so switching positions feels consistent with no sudden hard spots. Motion Isolation The Ergoflex 5G is a motion isolation champ. Because it’s all foam (no springs to bounce), movement on one side barely rattles the other. I could toss, turn, or even do a midnight stretch on my side and my partner didn’t budge. It absorbs energy; we joked it was like each sleeper has their own island of calm. One person’s flips and wiggles become mere whispers on the other side.
Temperature Regulation and Breathability Memory foam often traps body heat, but the 5G bucks that trend. It has a special Cool-Sleep airflow layer and a breathable TENCEL® cover. The cover wicks moisture and feels cool, and the foams have open-cell structures with ventilation channels.
In practice, this mattress stayed pleasantly cool. I tested it on a few warm nights, and it never felt like sleeping on a radiator. The ventilated core and cover keep body heat from building up. Plus, the cover zips off to wash if you need. Bottom line: if you sleep hot, this one does a better job at cooling than most foam beds.
Materials and Construction Cover: Quilted TENCEL® fabric that’s breathable and moisture-wicking. It zips off for washing.Comfort Layer: Thick (~9cm) viscoelastic memory foam (orthopaedic foam). It contours to your body to spread out weight and reduce pressure.Cool-Sleep Airflow Layer: About 5cm of perforated foam under the memory layer. It draws heat away and lets air flow through built-in channels, helping prevent overheating.Base Support Layer: High-density support foam forming a thick, firm foundation. (One-sided design - no flipping needed.)Certifications: All foams are CertiPUR-US® and OEKO-TEX® certified (no harmful chemicals). The mattress is hypoallergenic and resistant to dust mites, mould, and bacteria. The build feels premium. Off-gassing was negligible (I barely noticed any smell after opening it). The layers fit snugly in the cover, giving a solid, well-made feel. This isn’t a flimsy, trampoline-like bed; it’s a thoughtfully constructed foam system.
Durability and Long-Term Use The 5G is pretty solid. Its high-density foams resist permanent dents. After months of regular use (and even a little playful jumping), it looked and felt almost like new. The edges held firm too - sitting near the side felt as supportive as the centre, with no collapse.
The company backs this with a 10-year warranty, so they clearly trust its durability. Many owners report older Ergoflex mattresses lasting a decade or more, and this one should be no different. Just remember it’s one-sided, so rotate it (end to end) occasionally to help even out wear.
Ease of Setup and Use Unboxing the 5G is straightforward. It comes vacuum-sealed in a big box (about 30 kg for a double) - one person can manage it (two is easier). Just cut the wrap and it unrolls and inflates. It took about 24 hours to reach full thickness, though I was ready to try it after only a few hours. Off-gassing was minimal - just a faint new-foam smell at first, then nothing. The cover zips off for machine washing.
Value for Money The 5G isn’t a cheap mattress, but the company often slashes prices 30-50%. Consider what you get: thick high-quality foam layers, a clever cooling core, a washable cover, plus a 10-year warranty and 30-night trial. Those extras add up.
Many reviewers call it a great value. Even at full price it holds its own thanks to comfort and durability, and on sale it can feel like a steal. In short, you pay more than a bargain foam bed, but you get features and longevity that cheap ones lack.
Who Should Consider the Ergoflex 5G Mattress Ideal for: Back and stomach sleepers who need firm support. People with chronic back or joint pain who want pressure relief. Couples who appreciate excellent motion isolation. Allergy sufferers who like the hypoallergenic, washable cover. Anyone wanting a premium foam mattress (especially on sale) and willing to invest in long-lasting comfort.Not ideal for: Shoppers on a tight budget (cheaper foam beds exist). If you prefer a super-soft pillow-top or bouncy, springy feel, this firmer sinking foam may disappoint. It’s one-sided (no flipping) with only a 30-night trial, so you’ll need to decide quickly. If you crave ultra-plush softness above all, you might keep shopping. Summary: The Ergoflex 5G is a well-made memory foam mattress that contours nicely without trapping heat. It’s great for anyone needing firm, pressure-relieving support (especially if you share the bed). If that sounds like your kind of sleep experience, it’s worth a look. If instead you want something cloud-soft or ultra-budget, you might want to keep shopping.
