Product Description
The iDream Flex is designed for one specific job: working perfectly with an adjustable base. At 20 cm, it’s an all-foam mattress built to flex and move without resistance — whether you’re raising your head to read, elevating your legs to relieve pressure, or using a full zero-gravity position. The Aero Gel Memory Foam comfort layer and layered foam core make it a genuine upgrade on standard foam mattresses at this height, with a 10-year warranty that reflects its build quality.
Who This Suits
Anyone who owns or plans to buy an adjustable bed base is the core audience for the iDream Flex. It’s also well-suited to combination sleepers who move positions through the night, and those who like the contoured feel of memory foam but want something slimmer and more versatile than a full 25 cm mattress. It suits light-to-medium weight sleepers best at this height.
Why It’s Different
Most spring mattresses cannot be used with an adjustable base — repeated bending stresses the spring system and voids the warranty. The iDream Flex is specifically engineered as an all-foam construction that articulates freely. The combination of Aero Gel Memory Foam, High Resilience Foam, and a Core Base High Density Foam foundation means it flexes without delaminating or developing pressure points at the hinge areas.

Sleep Problems It Helps With
Acid reflux, snoring, poor circulation, and lower back tension are all conditions that an adjustable base can help manage — but only if your mattress cooperates. A spring mattress on an adjustable base is a recipe for a voided warranty and a damaged mattress within months.
The iDream Flex is built from the ground up for this use case. If you sleep hot and need memory foam that doesn’t trap heat, the Aero Gel layer is a specific fix for that.

What's Insided
Bamboo-derived fabric that naturally wicks moisture and regulates temperature — well suited to sleepers who tend to run warm.
Fully removable outer cover with a zip closure — machine washable for easy care and a consistently clean sleep surface.
Fitted cotton inner layer encasing the foam and spring core, keeping internal layers stable and protected when the outer zip cover is removed for washing.
Gel memory foam that moulds precisely to the body's shape, distributing weight evenly and relieving pressure across the hips, shoulders and lower back.
Dense, high-resilience foam maintaining spinal alignment when comfort layers above have compressed, holding its shape across years of regular sleep.
High-density polyurethane forming the structural base, preventing compression and sag in the layers above across the full mattress lifespan.
Non-woven base panel keeping the mattress firmly positioned on the bed base, preventing movement or creep during sleep.

Questions
The iDream Flex is compatible with all standard adjustable base profiles. If you’re unsure about a specific model, contact us at restmaker.au with your base details and we’ll confirm compatibility before you purchase.
Standard memory foam hugs your body and retains heat — many people find it too warm. Aero Gel Memory Foam gives you the same contouring feel but the gel particles actively pull heat away from your body. It’s noticeably cooler to sleep on, which is particularly relevant in Sydney’s warm summers.
For light-to-medium weight adults, yes. If you’re over 100 kg or prefer a thicker feel, the iDream Premium at 25 cm is the better choice — same adjustable-base compatibility with more foam depth.
Yes. Every Restmaker mattress includes a 100-Night Sleep Trial. Sleep on it for up to 100 nights and if it’s not right for you, we’ll arrange a hassle-free return — no questions asked.

Really impressed with the build firm. The queen feels solid but still softens in all the right places. Love that it was creators by people who clearly know company.
Upgraded from an old spring mattress and the difference with my adjustable base is night and day. The foam did have a slight chemical smell for the first couple of days.
Was worried it might feel too thin but it’s got great firm from the foam core underneath. firm feels premium for what I paid. Already told my sister to grab one.
onestly didn’t expect much at this price point but this thing punches way above its weight. You can tell the people behind it actually know firm inside and out, not just slapping foam together.
The trial period gave me peace of mind but onestly I knew within the first week I wasn’t sending it back. upports my shoulders and hips perfectly, no pressure points anyhere.
Replaced a sagging innerspring with this and wish I’d done it sooner. The long-single is perfect for my room, the company is consistent, and zero back pain since switching.
Switched from a spring mattress and don’t think I can go back. The gel layer is genuinely cool to lie on, even on warmer nights. Knocked one star off because it took longer than promised to arrive.
Sleeping on this for three months now and it’s held its shape beautifully. The gel foam layer is comfortable without being too soft, and the King gives us proper edge creators.
Our adjustable base was sitting there unused because our old mattress wouldn’t bend properly. This king one fixed that completely – super lexible and really comfortable for sleeping and watching TV.
Bought king size for our master bedroom and it’s a solid upgrade from our old spring mattress. Works great with the adjustable base. Minor issue is the edge expert could be a touch better but not a dealbreaker.
