WHAT IS AN FIRM MATTRESS

Firm doesn’t mean hard, it means supported.

An firm mattress sits between 7.5 and 9 on the firmness scale. It feels solid and stable, with comfort layers above the support core that stop it from feeling rigid. Sleepers who prefer to sleep on top of the mattress rather than sink into it will love the steady, supportive feel of a true firm mattress.

Every Luxe firm mattress is hand built in our UK workshop using premium pocket springs, reflex foam or natural latex, paired with breathable comfort layers and OEKO-TEX certified covers. Browse the five firm mattress collections below and find the right match for your sleep style.

Inside a Luxe firm mattress

The four-layer anatomy of every Luxe firm mattress.

Every Luxe firm mattress is built around the same four-layer formula — a breathable quilted cover, a thin pressure-relief layer, a high-density transition foam, and a reinforced support core. Each collection tunes the recipe for a different sleeper.

  1. 01

    Breathable quilted cover

    OEKO-TEX certified knitted or Tencel cover, hand tufted with British wool to wick moisture and keep the surface temperature neutral.
  2. 02

    Thin pressure-relief layer

    A shallow comfort layer takes the edge off at the hips and shoulders without letting you sink — the detail that stops an firm mattress feeling harsh.
  3. 03

    High-density transition foam

    Reflex and PU foams above 35 kg/m³ hold the comfort layer up and stop any sag, which is where an firm mattress earns its 10-year-plus lifespan.
  4. 04

    Reinforced support core

    Up to 5,000 hand nested pocket springs, high-density reflex foam or natural latex, with a firmer perimeter for edge-to-edge support.

WHY FIRM

Six reasons sleepers choose an firm mattress.

An firm mattress is built for stability, support and durability. Here is what makes a Luxe firm mattress different from softer counterparts.

Stable, supportive feel

An firm mattress keeps you on top of the bed with a steady, supportive surface — the feel many sleepers prefer.

Built to last 10 years plus

Higher density foams and tempered springs mean a Luxe firm mattress holds its supportive feel far longer than softer counterparts.

Great for couples and back sleepers

Firm mattresses prevent the deep sinking common with softer beds — the sleep position back and stomach sleepers prefer.

Edge to edge support

Sit, sleep and rise from any side without roll off. Firm mattresses use the full sleep surface for couples sharing a bed.

Better airflow and cooling

You sleep on an firm mattress, not in it. Less material around the body means more airflow and naturally cooler nights.

Premium British craftsmanship

Every Luxe firm mattress is hand tufted, hand stitched and finished in our UK workshop by master mattress makers.

INSIDE A LUXE FIRM MATTRESS

Premium materials, precision built.

Every Luxe firm mattress is built from the inside out with materials chosen for performance, comfort and a 10 year plus lifespan — from hand nested pocket springs to natural Talalay latex.

01

Hand nested pocket spring core

Up to 5,000 individually pocketed springs respond independently for a supportive feel and excellent motion isolation.

02

High density support foams

Reflex and PU foams above 35 kg/m³ form the supportive base of every firm mattress — the layer responsible for 10 years plus of durability.

03

Active LTX cooling technology

Phase change cooling foam in our hot sleeper range absorbs and redistributes body heat to keep the sleep surface noticeably cooler.

04

Natural Talalay and Dunlop latex

Responsibly sourced botanical latex provides instant responsiveness, breathability and natural hypoallergenic protection.

05

Hand tufted natural fibre fillings

British wool, organic cotton and silk hand tufted into the mattress to lock layers in place and aid temperature regulation.

06

Independently certified

OEKO-TEX Standard 100 fabrics, FIRA sleep tested for 10 years of nightly use, made in Great Britain under the NBF Code of Practice.

Firm vs other firmness levels

How a firm mattress compares to extra firm and medium firm.

Firmness is the single biggest factor in whether a mattress works for you. Here is how a firm mattress compares to the levels either side of it on the things that actually matter.

Firm (Luxe)

  • Firmness: 7.5 to 9 out of 10.
  • Feel: Supportive and stable, with a little give at the surface.
  • Support: Strong — spine stays level, slight contour at the shoulders.
  • Cooling: Very good — you sleep on it rather than in it.
  • Lifespan: 10 to 15 years, 10-year warranty.
  • Best for: Back sleepers, couples, back pain, anyone who finds medium too soft.

Extra firm

  • Firmness: 8.5 to 9.5 out of 10.
  • Feel: Solid — almost no sink at all.
  • Support: Maximum, with minimal cushioning at the surface.
  • Cooling: Excellent.
  • Lifespan: 10 to 15 years.
  • Best for: Heavier sleepers and stomach sleepers who want no give.

Medium firm

  • Firmness: 5 to 6.5 out of 10.
  • Feel: Balanced — noticeable sink at the hips and shoulders.
  • Support: Good for average body weights, less so above 16 stone.
  • Cooling: Moderate — more material around the body.
  • Lifespan: 8 to 10 years.
  • Best for: Side sleepers and combination sleepers.

Firm mattress FAQs

Your firm mattress questions, answered.

What does an firm mattress feel like?
An firm mattress feels stable and supportive. You sleep on top of the surface rather than sinking into it, with a thin contouring comfort layer above a high density support core. Luxe firm mattresses sit between 7.5 and 9 on a 10 point firmness scale.
Who is an firm mattress best for?
An firm mattress suits sleepers who prefer a supportive, stable feel. It is popular with couples sharing a bed, larger sleepers, back and stomach sleepers, and anyone who has previously found softer mattresses too sinky or unsupportive.
Which Luxe firm mattress is best for hot sleepers?
If you sleep warm, our Firm Hybrid Mattress for Hot Sleepers and Firm Latex Mattress are both excellent choices. The cooling hybrid uses phase change foam with ventilated springs, while latex is naturally cooling thanks to its open cell structure.
How long does an firm mattress last?
A high quality firm mattress like ours typically lasts 10 to 15 years. Higher density foams (35 kg/m³ and above) and tempered pocket springs hold their structure far longer than the materials used in budget mattresses. Every Luxe firm mattress is backed by a 10 year warranty.
Can an firm mattress feel too firm?
Yes, a mattress that is too firm for your body weight or sleep style can feel uncomfortable. Our firm mattress collections sit between 7.5 and 9 out of 10 on the firmness scale — firm but never harsh. Our 100 night sleep trial means you can be sure it is the right fit.
Do you deliver firm mattresses across the UK for free?
Yes, every firm mattress in our collection ships with free, fully tracked, white glove 2 man UK delivery. We unpack and position your firm mattress in your room of choice, and we will happily remove your old mattress if requested.
What is the difference between a firm and an extra firm mattress?
Firm mattresses sit between 7.5 and 9 on the firmness scale, while extra firm mattresses sit between 8.5 and 9.5. A firm mattress keeps a small amount of give from its comfort layers, which most back sleepers prefer; extra firm gives an even more solid surface with minimal cushioning.
Is an firm mattress good for back pain?
For many sleepers, yes. An firm mattress keeps the spine level and stops the hips dropping, which is the most common cause of lower back pain on a mattress that is too soft. Back and stomach sleepers, and anyone over roughly 16 stone, usually get the most benefit.
Can I use an firm mattress on a slatted bed frame?
Yes, every Luxe firm mattress works on a sprung slatted, solid slatted or platform-top bed base. Slats should be no more than 7 cm apart for the warranty to remain valid. Divan and ottoman bases are also fully compatible.
