Product Description
The iSleep Hybrid Firm is a 30 cm hybrid mattress that pairs an Adaptive 3-Zone Pocket Spring system with a Euro Top and Firm High Resilience Foam — delivering the edge-to-edge support of a premium spring system with the targeted firmness that back sleepers and heavier bodies need. It’s the firm option in Restmaker’s Hybrid range: built for Sydneysiders who’ve tried soft mattresses and keep waking up with their back in knots.
Who This Suits
Back sleepers who need serious lumbar support, stomach sleepers who need their hips held in line with their spine, and heavier-framed sleepers who compress medium mattresses too far. The iSleep Hybrid Firm also suits people who prefer a responsive, buoyant feel under them rather than the sinking sensation of foam-heavy mattresses. If you share a bed and one partner needs firm support, the 3-Zone Pocket Spring keeps their movement from disturbing you.
Why It’s Different
A 3-Zone Pocket Spring system is a significant engineering step up from standard pocket springs. Rather than uniform spring tension across the whole mattress, it delivers targeted support to your head and shoulders, your back and hips, and your legs and feet — the three areas that need different amounts of support in a firm mattress. That precision, combined with genuine Firm High Resilience Foam and a Euro Top finish, is what separates the Hybrid Firm from generic firm mattresses at similar prices. Within the Restmaker range, the Hybrid Firm sits between the Wellness Firm (5-Zone pocket spring, no foam layer) and the Natural Comfort Firm (premium 7-Zone, 36 cm, 12-year warranty). If you want a hybrid spring-plus-foam construction at an upper-mid price, the Hybrid Firm delivers that more efficiently than any pocket-spring-only mattress at this level.

Sleep Problems It Helps With
Back pain sufferers in Sydney consistently tell us that their old medium mattress is the problem — it feels okay for the first hour but by 3 am their lower back is screaming. A firm hybrid keeps your lumbar spine in neutral alignment all night rather than letting it sag into the mattress. The 3-Zone spring system provides higher tension at the lumbar zone specifically — not uniform firmness across the whole surface, but targeted resistance where back sleepers need it most.
Stomach sleepers whose hips drop too far, causing their lower back to arch, will find the Hybrid Firm dramatically more comfortable than a medium. The Firm High Resilience Foam prevents the hip from sinking, keeping the spine from arching overnight.
For heavier builds who've been through multiple medium mattresses and found them sagging within a few years: the Firm High Resilience Foam is specifically rated for high-compression resistance. It holds its profile under sustained heavy loads far longer than standard foam.
Hot sleepers who've been avoiding hybrids because they assume spring systems trap heat: the Hybrid Firm's CoolFabric actively promotes airflow at the sleep surface, and the spring system itself creates natural ventilation channels through the mattress body. The hybrid construction breathes better than a foam-only mattress at this price point.

It's a genuine firm — not a marketing-label firm. The combination of Firm High Resilience Foam and a firm-tensioned 3-Zone Pocket Spring gives you a mattress that has clear pushback and won't let your hips or shoulders sink in significantly. If you've slept on firm hotel mattresses and liked them, this is that feel.

My physio recommended a item item and this one ticked all the boxes. The pocket springs actually work, no feeling my partner move at night anymore.
onestly the best mattress I’ve owned. You can tell whoever company this knew what they were doing because the expert is even across the whole surface.
Bought this for our guest room and ended up keeping it for ourselves. That good. Unit, brand, and the king size is properly sized.
Perfect for hot sleepers too. The expert label design doesn’t trap heat like my old memory foam. Stays cool all night even in summer.
Heavier build (around 110kg) and this mattress handles it perfectly. No sinkage, still feels selection and brand after months of use.
Nervous about buying a mattress online but the queen item unit exceeded expectations. Edge label is actually decent and it feels premium throughout.
Really happy with this mattress. It’s properly sleep surface without feeling like a board – great expert and stays cool through the night.
Did the maths and this was way firm than the big name brands we looked at. firm feels just as good if not better.
Partner rolls around a lot and I barely feel it now. Motion isolation is way better than our old spring mattress, I can actually sleep through the night.
onestly the best mattress I’ve owned. The item construction means you get company AND comfort. My back pain is basically gone.
