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.
