Naturalmat Mattress is a premium lineup of handmade, natural-material mattresses built in Devon, with the range split between bouncier pocket-sprung designs and firmer natural-fibre builds. I evaluated support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability across four core models. Expect excellent breathability and stable support, with the main trade-offs being contour depth (especially on the firmer natural-fibre option) and more “buoyant” feel on the latex-forward builds.

How We Tested It
We rotated between back, side, and mixed-position nights and scored each Naturalmat Mattress on Support, Cooling, Pressure Relief, Motion Isolation, Responsiveness, Edge Support, and Durability. I focused on lumbar support and alignment across full nights, while Marcus stressed heat buildup and hip support, and Jamal paid extra attention to repositioning ease and edge stability during daily routines. We used the same pillows and bedding to reduce variables, then compared notes after repeat nights to check consistency rather than one-off impressions.
Naturalmat Mattress: Our Testing Experience
The Splendid Mattress
Our Testing Experience

The Splendid settled in quickly for us. The surface felt clean and buoyant rather than “sinky,” and I noticed I could change positions without that little tug you get on grabbier foams. Marcus gravitated toward firmer tension for hip support, and it kept his midsection from dipping when he rolled forward. Jamal liked how easy it was to get out of bed without feeling unstable at the edge, especially during quick morning starts.
What we liked:
- Balanced spring-and-fibre feel
- Easy position changes
- Breathable sleep surface
Who it is best for:
- Back/side combination sleepers
- People who dislike foam “hug”
- Bedrooms that run warm
Where it falls short:
- Not the plushest option
- Less “cradle” for shoulders
- Moderate motion damping

Pros & Cons
| Pros | Cons |
|---|---|
| Balanced support; buoyant feel; breathable materials | Not ultra-plush; motion isolation is only moderate |
| Multiple tension options; practical sizing options | May feel too “spring-present” for foam lovers |

The Superb Mattress
Our Testing Experience

The Superb was the easiest to “read” in the first week: it felt supportive right away, but the latex element gave it a supple lift that kept me from feeling locked in. Marcus called out the temperature control as the biggest difference—less of that slow warmth creep around the torso. I kept coming back to how consistent the middle of the bed felt; even on nights when I drifted from side to back, my hips didn’t feel like they were negotiating two different surfaces.
What we liked:
- Supple, buoyant support
- Strong breathability
- Consistent feel across positions
Who it is best for:
- Combination sleepers
- Hot sleepers
- People who want “lift,” not sink
Where it falls short:
- Not a slow-melting feel
- Bounce can carry movement
- Firm tension feels taut

Pros & Cons
| Pros | Cons |
|---|---|
| All-around balance; latex buoyancy; strong temperature regulation | Less of a deep cradle; moderate motion transfer |
| Soft/medium/firm tensions; Zip & Link available | May feel too lively for foam-first sleepers |
Details
- Type: Pocket sprung mattress.
- Mattress depth: 25cm.
- Tension options: soft, medium, firm.

| Edge Support | 4.3 | Reliable sitting edge and usable perimeter |
| Durability | 4.4 | Construction feels resilient; materials suggest longevity |
| Overall | 4.4 | The most balanced pick for most sleepers |
The Sumptuous Mattress
Our Testing Experience

The Sumptuous felt like the “quiet luxury” of the group—more depth to the comfort without turning marshmallow-soft. I noticed the surface smoothing out pressure points when I read in bed for a long stretch; it stayed comfortable without that creeping need to change position. Jamal liked the rebound when he rotated from side to back after late workouts, and Marcus appreciated that the support didn’t collapse even when he tried to force a hammock-like dip.
What we liked:
- Deep comfort without sag
- Support stays composed
- Breathable, not stuffy
Who it is best for:
- Side/back hybrids
- People wanting refined plush
- Those who still need support
Where it falls short:
- More “feel” of movement
- Overkill for minimalists
- Bulkier to rotate

Pros & Cons
| Pros | Cons |
|---|---|
| Most premium comfort feel; strong support; excellent long-session comfort | Not the most motion-deadening; big, substantial build |
| Coir and latex add structure; multiple tensions available | Can feel too buoyant for slow-sink preferences |
Details
- Type: Pocket sprung mattress.
- Mattress depth: 27cm.
- Tension options: soft, medium, firm.
- Materials highlighted: natural latex, organic coir, pocket springs, organic wool, organic cotton cover (cotton/wool blend).

- Sleep trial: 45 Day Sleep Promise.
- Warranty: 10-year guarantee.

| Motion Isolation | 4.1 | Comfort layers dampen some movement, not all |
| Responsiveness | 4.5 | Buoyant, easy repositioning with a smoother feel |
| Edge Support | 4.4 | Stable edge for sitting and side sleeping near perimeter |
| Durability | 4.7 | Coir + construction feel built for long haul |
| Overall | 4.5 | The best comfort-forward option that still supports |
The Lambswool Mattress
Our Testing Experience

The Lambswool played its hand immediately: denser, firmer, and more “platform-stable” than the pocket-sprung trio. On back-sleep nights, I felt very even support—no sense of my hips dropping as the night went on. Marcus liked how direct the support felt when he rolled toward his stomach; it didn’t get mushy. The trade-off showed up most when I stayed on my side for long stretches: less contouring, so I had to be more deliberate with pillow height and shoulder positioning.
What we liked:
- Dense, stable support
- Breathable, non-stuffy feel
- No “stuck” sensation
Who it is best for:
- Back/stomach sleepers
- Firmness-first shoppers
- People who want stability
Where it falls short:
- Less shoulder/hip contour
- Motion damping is moderate
- Lower profile build

Pros & Cons
| Pros | Cons |
|---|---|
| Firm, denser feel; strong spinal steadiness; breathable materials | Less pressure relief for strict side sleepers |
| Stable surface for moving and stretching; clean rebound | Not the plushest option; lower-profile feel |
Details
- Type: Natural fibre mattress.
- Mattress depth: 21cm.
- Firmness positioning: described as a medium firmness natural fibre mattress with a firmer, denser feel.
- Materials highlighted: organic coir core, natural latex layers, organic wool, organic cotton cover (cotton/wool blend).
- Cover approach: organic cotton/wool blend designed to meet fire safety requirements without chemical fire retardants; hypoallergenic finishing (geraniol treatment).
- Sleep trial: 45 Day Sleep Promise.
- Warranty: 10-year guarantee.
- Options: made-to-measure sizing and Zip & Link.

| Edge Support | 4.0 | Good perimeter stability, with a thinner profile |

| The Splendid Mattress | 4.2 | 4.4 | 4.1 | 4.3 | 4.0 | 4.1 | 4.2 |

| The Lambswool Mattress | 4.2 | 4.6 | 3.8 | 4.4 | 3.9 | 4.5 | 4.3 |
The most evenly strong performers are The Superb and The Sumptuous, with fewer weak spots across categories. The Sumptuous shows its clearest advantage in pressure relief and durability, while The Superb stands out for responsive, breathable all-position comfort. The Lambswool is the most specialized: excellent support and durability, but a clearer trade-off in pressure relief for side sleepers.

Pro Tips for Naturalmat Mattress
- Pick tension by how your hips behave: if you dip, go firmer; if your shoulders feel jammed, go softer.
- Give your body a week of consistent sleeping before judging; nightly variability can mislead.
- If you’re a side sleeper, prioritize shoulder comfort first—hip comfort often follows.
- For hot sleepers, keep the bedding breathable; heavy comforters can mask mattress airflow.
- When testing in your home, use your usual pillow; pillow height can “fake” mattress support issues.
- Rotate the mattress periodically to even out wear, especially if you sleep in one spot.
- If you’re moving into a tight stairwell, consider Zip & Link to avoid delivery headaches.
- If you have allergy concerns, focus on your full sleep system: protector, sheets, and regular washing routines.
- For firmer models, a small change in pillow loft can reduce neck and shoulder strain.
- Track wake-up stiffness vs. bedtime comfort; the morning is where support shows up.
