Product Description
The iSleep Support is built for sleepers who need firm, structured support — particularly those dealing with lower back discomfort, heavier builds, or a strong preference for a mattress that doesn’t give too much. At 25 cm with a Firm Adaptive Pocket Spring and Firm High Resilience Foam, it keeps your spine properly aligned throughout the night. Covered in bamboo fabric with eco-friendly construction, it delivers serious support without sacrificing comfort.
Who This Suits
Back sleepers and stomach sleepers are the core audience for the iSleep Support — both positions benefit from a firmer surface that keeps the lumbar spine from sinking out of alignment. Heavier-framed sleepers who find medium mattresses compress too far will appreciate how the Support maintains consistent pushback. It’s also a solid choice for anyone recovering from a back injury where a firm, stable surface is part of the recovery plan.
Why It’s Different
A lot of mattresses labelled ‘firm’ are simply medium mattresses with slightly denser foam — they still compress under a heavier body. The iSleep Support uses a specifically engineered Firm Adaptive Pocket Spring system and Firm High Resilience Foam, calibrated to resist compression at higher body weights and maintain spinal alignment. This comes from 25+ years of industry expertise, not a marketing label.

Sleep Problems It Helps With
Lower back pain on waking is one of the most common complaints we hear from Sydney customers — and the usual culprit is a mattress that lets the lumbar spine sag overnight. The iSleep Support is designed specifically to prevent that, keeping your lower back level with your hips and shoulders. If you’ve been waking up needing to stretch your lower back just to get moving, a properly firm mattress is usually the most direct fix.

Questions
A firm mattress is often recommended for back pain sufferers, and the Support is one of the firmer options in the Restmaker range. That said, mattress needs vary between individuals. The 100-Night Trial gives you time to properly assess whether it’s the right fit for your body.

Stays cool through summer nights which I didn’t expect from a firm mattress. The cover material really does help.
Was nervous ordering online without testing but the trial period gave me confidence. Turns out I had nothing to worry about — it’s exactly what I needed.
I’m a bigger build and other brand sag in the middle after a few months. This queen has held up perfectly since day one. Really impressed.
Sturdy enough for proper sleep surface but with enough give to be actually comfortable. The king size fits our room perfectly and the cover feels really breathable.
It’s heavy but that’s expected for a king. Moving it once into position and it stays put. The base doesn’t slide around on our timber floor.
Took the plunge after my old mattress was wrecking my back. Wish I’d done it sooner onestly. The structured selection keeps everything aligned and I haven’t woken up stiff since.
Bought this for my teen’s room in the double size. She used to complain about her old mattress and now she’s out cold the second her head hits the pillow.
This mattress has the kind of firm item that takes a few nights to appreciate but now I sleep so much better. Single size was exactly what I needed.
I was hesitant to buy a mattress online but the trial period took all the risk out of it. Glad I did — this is the firmest, most upportive mattress I’ve owned without being uncomfortable. Sleep maker has massively improved.
Finally a firm mattress that doesn’t feel like sleeping on a rock. The pocket springs give just enough give while keeping everything aligned. Super happy with the double size for our room.
