Best Mattress for Heavy People in Australia (2026 Guide)
Quick Answer
What is the best mattress for heavy people in Australia? For most heavier sleepers (roughly 100 kg and up), the Newentor Hybrid Pro is our pick: its dual-spring construction — 7-zone pocket springs plus a layer of micro-coils — provides deep, durable support where heavier bodies need it, and reinforced edges keep the full surface usable.
Key rule: support matters more than surface firmness. A mattress can feel plush yet still support you properly — what counts is the spring system underneath.
Budget option: the standard Newentor Hybrid (medium-firm, 7-zone) works well up to around 110 kg.
Test it at home: every Newentor mattress comes with a 120-night risk-free trial and a 10-year warranty.
Why body weight changes what you need from a mattress
The heavier you are, the deeper you compress a mattress. On a mattress built for average weights, a heavier sleeper sinks past the comfort layers and into the support core, which causes three problems: the hips drop out of line with the spine, pressure builds at the shoulders and hips, and the foam breaks down faster — the sagging you see in older mattresses.
That's why "just buy the firmest mattress" is bad advice. What heavier sleepers actually need is a mattress that resists deep compression while still cushioning pressure points. That comes from the construction — coil strength, zoning and layer quality — not from a hard surface.
What to look for if you're over ~100 kg
Pocket springs over all-foam. Steel springs push back progressively the more you compress them, so they keep supporting heavier bodies where foam simply flattens. A spring core also holds its shape for years longer under higher loads.
Zoned support. Your hips carry most of your weight. A 7-zone spring system is firmer under the hips and lower back and softer under the shoulders, keeping the spine level instead of sagging into a hammock shape.
Reinforced edges. Heavier sleepers put far more load on the perimeter when sitting or sleeping near the edge. Weak edges collapse first — reinforced edge coils keep the full mattress width usable.
A real warranty against sagging. Check what depth of indentation the warranty actually covers. Newentor's 10-year warranty covers visible indentation greater than 20 mm — a concrete, measurable standard.
Best feel by sleep position (for heavier bodies)
| Sleep position | Best feel | Why |
|---|---|---|
| Back | Medium-firm with zoned support | Keeps the hips from sinking below the lumbar curve |
| Side | Medium-firm with pressure relief | Heavier side sleepers need cushioning at the shoulder and hip plus strong support at the waist |
| Stomach | Firmer | Prevents the pelvis from sinking and arching the lower back |
| Couples (higher combined weight) | Dual-spring hybrid with reinforced edges | More total load needs stronger springs, motion isolation and usable edges |
Our top pick for heavy people: the Newentor Hybrid Pro
The Newentor Hybrid Pro is built around exactly the features above: a dual-spring system that stacks micro-coils on top of 7-zone pocket springs, CertiPUR-US certified comfort foams, and reinforced edge support.
An honest note on feel: the Hybrid Pro's surface is slightly softer than the standard Newentor Hybrid. Don't let that put you off — support and surface feel are different things. Under a heavier body, the Pro's two spring layers engage and push back progressively, so you get deep support with pressure relief on top, rather than the "sleeping on a board" feel of a merely hard mattress. Bedbuyer, one of Australia's best-known independent mattress reviewers, rates the Hybrid Pro 3.9 out of 5.
If you're under ~110 kg and prefer a firmer surface, the standard Newentor Hybrid (medium-firm, 7-zone) remains the better-value pick.
Durability and sagging: what to expect
Sagging is the number-one long-term complaint heavier sleepers have about mattresses — usually because foam-heavy builds break down under sustained load. Spring cores resist this far better. Two practical tips: rotate the mattress head-to-foot every few months to even out wear, and use a proper supportive base (slatted frames, box springs, foundations and floor placement all work for Newentor mattresses). If a genuine defect appears, the 10-year warranty covers indentation beyond 20 mm.
When to see a professional
A better mattress improves sleep comfort, but it isn't a medical treatment. If you have persistent joint pain, back pain, or symptoms of sleep apnoea — which is more common at higher body weights — talk to your GP or a sleep specialist. The Sleep Health Foundation has evidence-based resources on sleep health for Australians.
