The iSleep Hybrid Medium is the all-rounder in Restmaker’s Hybrid range — a 30 cm mattress that brings together Aero Gel Memory Foam, High Resilience Foam, and an Adaptive 3-Zone Pocket Spring into one balanced sleep system. It’s the mattress we most often recommend to Sydney couples who can’t agree on soft or firm, combination sleepers who shift positions through the night, and buyers who want the best of both foam and spring technology without stepping into the premium price bracket.

Who This Suits

This is the mattress for couples with different sleep styles — back sleeper and side sleeper, light and heavy, warm and cold. The 3-Zone Pocket Spring gives genuine spinal support to back sleepers while the memory foam comfort layers cushion side sleepers at the shoulders and hips. Combination sleepers who rotate between positions find it adapts well to each. It handles Sydney’s warm summers with the CoolFabric and gel foam working together to manage heat.

Why It’s Different

Hybrid mattresses exist on a wide spectrum — some are foam mattresses with a thin spring layer, others are spring mattresses with a foam topper. The iSleep Hybrid Medium is genuinely engineered as a hybrid: the Adaptive 3-Zone Pocket Spring does serious structural work, and the Aero Gel Memory Foam layer does serious comfort work. Neither is an afterthought. That balance — calibrated by a team with 25+ years of mattress industry expertise — is what makes it stand out at this price point in the Sydney market. Within the Restmaker range, the Hybrid Medium is the direct comparison point for the Wellness Medium — both are 30 cm upper-mid mattresses with medium feel. The Hybrid adds Aero Gel Memory Foam to the spring system for a more advanced comfort layer; the Wellness Medium uses a 5-Zone Pocket Spring for more targeted zonal support. Foam comfort plus springs, or more spring zones — that’s the decision between them.
