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.

Replaced our old mattress and the difference is night and day. Selection, store, and the unit design is way better than basic spring label. Highly recommend.
Bought the King for our guest room and onestly it’s better than the one in our own bedroom. Going to upgrade ours next month for sure.
Got the Queen and it’s been brilliant for my back. The firm store expert keeps my spine aligned without feeling like I’m sleeping on a board. Way better than my old spring one.
The euro top adds just enough give to stop it feeling like sleeping on a board. Item creators you need it, comfortable company you want it. Great queen mattress.
Bought this after reading reviews for weeks and finally pulled the trigger. So glad I did — the irmness is exactly what I needed for my bad lower back.
Was worried a sleep surface mattress would feel like sleeping on a board but this has just the right balance. Love the double size too.
The transition from our old spring mattress was seamless and this feels even better. Sleep Surface enough for firm but with a subtle cushioned feel on top.
This mattress has that well-expert feel to it — you can tell it’s been brand by people who really know sleep. Unit firm without feeling like sleeping on concrete.
