Natural Mattresses

Natural Mattresses: The Ultimate Buying Guide

Natural mattresses use materials such as wool, cotton and other natural fibres within their comfort layers, often combined with pocket spring systems and traditional upholstery techniques. These materials can provide cushioning, breathability and a responsive sleeping feel without relying entirely on synthetic foam.

Not every mattress described as natural contains the same materials or the same proportion of natural upholstery. The type and quantity of fillings, spring system, firmness, tufting and overall construction all contribute to how the mattress feels. Looking at the full specification is therefore more useful than relying on the word “natural” alone.

1. Natural Mattress Fillings

Natural mattresses can contain a variety of comfort materials, including wool, cotton and other natural fibres. These fillings are layered above and around the spring system to create cushioning and contribute to the overall sleeping feel.

Different combinations create different levels of softness, resilience and breathability, so the exact filling specification is important when comparing individual mattresses.

2. Wool in Natural Mattresses

Wool is commonly used in traditionally upholstered mattresses because it provides soft cushioning and has natural temperature-regulating properties.

It can help create a comfortable sleeping environment across changing seasons while also adding loft and resilience to the upholstery layers.

The amount and position of wool within the mattress varies considerably between products, so check the individual specification where natural wool content is important to you.

3. Cotton and Other Natural Fibres

Cotton is often used alongside wool and other natural materials within mattress upholstery.

It provides soft, breathable cushioning and can help create a lighter, more responsive comfort layer above the spring system.

Some mattresses also incorporate additional natural fibres depending on the manufacturer and range. The blend of materials contributes to both the feel and character of the mattress.

4. Pocket Sprung Natural Mattresses

Many Pocket Sprung Mattresses use natural upholstery above the spring system.

Individual pocket springs respond independently to pressure, while layers of wool, cotton and other fibres provide the cushioning above them.

This combination can create a responsive, traditionally upholstered mattress with good airflow through the spring unit and natural comfort materials at the surface.

5. Hand-Tufted Construction

Natural and traditionally upholstered mattresses are often hand tufted.

Tufting secures the layers of fillings through the depth of the mattress, helping keep the upholstery in position and stabilise the construction.

The visible tufts are therefore not merely decorative; they are part of the way the mattress is held together.

6. Natural Mattress Firmness

Natural fillings don't determine whether a mattress is soft or firm. The overall firmness comes from the combination of spring tension, upholstery and mattress construction.

Our range includes Soft Mattresses, Medium Mattresses, Medium-Firm Mattresses and Firm Mattresses.

• Soft: More cushioning and greater initial sink into the upholstery.
• Medium: A balanced combination of cushioning and support.
• Medium-Firm: A more supportive feel while retaining noticeable comfort.
• Firm: A more substantial sleeping surface with less initial sink.

Firmness remains subjective and can feel different depending on body weight, sleeping position and the bed base underneath.

7. Breathability and Temperature Regulation

Natural materials are often chosen for their breathability and ability to manage moisture and temperature within the sleeping environment.

Wool in particular is commonly valued for its ability to help regulate warmth, while cotton and other breathable fibres can encourage airflow through the comfort layers.

The spring unit can also provide open space within the mattress structure, allowing more air movement than some dense all-foam constructions.

8. Natural Mattresses vs Memory Foam

Memory Foam Mattresses and natural mattresses provide quite different sleeping sensations.

Memory foam contours more closely around the body and tends to create a more enveloping feel, while natural upholstery generally feels more responsive and buoyant.

Neither construction is automatically better. The right choice depends on whether you prefer a more contouring foam feel or a more traditionally upholstered sleeping surface.

9. Natural Mattresses vs Hybrid Mattresses

Hybrid Mattresses usually combine springs with foam or other performance materials, while natural mattresses focus more heavily on natural upholstery such as wool and cotton.

Some mattresses can blur these categories by combining springs, natural fibres and modern performance materials within the same design.

The most useful approach is to compare the actual spring system, comfort layers and firmness rather than relying on the category name alone.

10. Natural Mattresses and Cool Gel

Cool Gel Mattresses use engineered cooling technologies, while natural mattresses tend to rely more on the inherent breathability of their upholstery materials.

These are different approaches to temperature management rather than direct alternatives. Some sleepers prefer the feel of natural fibres, while others prefer foam-based cooling technologies.

11. Natural Orthopaedic Mattresses

Natural fillings can also be used within firmer or Orthopaedic Mattresses.

A firmer pocket spring system can be combined with wool, cotton or other natural upholstery to create a substantial sleeping surface without relying solely on foam.

The orthopaedic description relates more to the intended support and firmness than to the type of filling used.

12. Natural Mattress Sizes

Natural mattresses are available across many standard UK mattress sizes:

• 2ft6 Small Single Mattresses – approximately 2ft6 x 6ft3 (76cm x 190cm)
• 3ft Single Mattresses – approximately 3ft x 6ft3 (92cm x 190cm)
• 4ft Small Double Mattresses – approximately 4ft x 6ft3 (122cm x 190cm)
• 4ft6 Double Mattresses – approximately 4ft6 x 6ft3 (137cm x 190cm)

• 6ft Zip & Link Super King Mattresses – approximately 6ft x 6ft6 (183cm x 200cm) when joined

Not every natural mattress is produced in every size, so check the options available on the individual product page.

13. Natural Mattresses for Couples

Natural pocket sprung mattresses can work particularly well for couples because independently moving pocket springs allow different areas of the mattress to respond separately to pressure.

Natural upholstery also tends to retain a more buoyant, responsive feel than dense memory foam, which some couples may prefer.

Mattress width, firmness and edge support should also be considered when two people regularly share the bed.

14. Edge Support

Some natural pocket sprung mattresses incorporate reinforced edge support using firmer perimeter springs or specialist border systems.

This can help create a more stable sensation around the outside of the mattress and maximise the usable sleeping area.

Edge construction varies between individual mattresses, so check the product specification where this feature is important.

15. Mattress Depth

Natural mattresses can be relatively deep because they may contain substantial pocket spring systems and several layers of upholstery.

A deeper mattress isn't automatically better. What matters is the quality and purpose of the materials inside it and how the layers work together.

Depth also contributes to the overall height of the finished bed, particularly when combined with a tall divan base.

16. Platform-Top Divan Bases

A platform-top divan provides a stable, firm surface underneath the mattress.

This can allow the natural mattress itself to provide most of the cushioning and responsiveness while the base remains relatively rigid.

The same mattress can therefore feel slightly firmer on a platform top than on a sprung divan base.

17. Sprung Divan Bases

A sprung divan base introduces another layer of cushioning and responsiveness underneath the mattress.

This can complement a natural pocket sprung mattress and create a softer, more responsive overall bed feel.

The base and mattress should therefore be considered together rather than treating the mattress as the only factor affecting comfort.

18. Slatted Bed Frames

Natural pocket sprung mattresses can also be used on suitable slatted bed frames where permitted by the mattress manufacturer.

Solid slats generally provide firmer support, while sprung slats introduce some additional flexibility.

Always check the maximum recommended spacing between the slats, particularly with pocket sprung mattress constructions.

19. Natural Mattresses and Ottoman Beds

Natural mattresses can be used on compatible ottoman beds, but mattress weight is important.

Deep pocket sprung mattresses with substantial natural upholstery can be relatively heavy. The ottoman's gas-lift pistons need to be designed to work with the weight of the mattress being used.

Always check the mattress weight against the specification of the individual ottoman bed.

20. Single-Sided and Double-Sided Natural Mattresses

Natural mattresses can be either single-sided or double-sided.

Double-sided designs often feature upholstery on both surfaces and can be turned as well as rotated, while single-sided designs generally require rotation from head to foot.

Traditionally upholstered mattresses can be substantial and heavy, so follow the manufacturer's handling and care instructions.

21. Settlement of Natural Fillings

Natural upholstery layers can compress and settle with normal use as the mattress adapts to the sleeper.

This settlement is different from structural failure and is a normal characteristic of many traditionally upholstered mattresses.

Regular turning or rotation where recommended can help encourage the fillings to settle more evenly across the sleeping surface.

22. Mattress Protectors and Natural Materials

A suitable mattress protector can help protect natural upholstery from spills, moisture and everyday wear.

Breathability is one of the attractions of natural mattress fillings, so choose a protector that doesn't unnecessarily restrict airflow or alter the feel of the mattress.

Always check the care and warranty instructions supplied with the mattress.

23. Rolled Natural Mattresses

Some mattresses containing natural fibres may also be available within our Rolled Mattresses range, depending on their construction.

However, traditionally upholstered mattresses with substantial natural fillings aren't always suitable for compression and may instead be delivered flat.

Packaging method doesn't determine mattress quality; it simply reflects what the particular construction allows.

24. Comparing Natural Content

The phrase “natural mattress” can cover a wide range of constructions. One mattress may contain several substantial natural upholstery layers, while another may use natural fibres alongside synthetic comfort materials.

If the amount or type of natural content is important to you, read the individual specification carefully rather than relying solely on the product name.

Look for clear details about the materials used and how they are incorporated into the mattress.

25. Mattress Care and Long-Term Performance

Use the mattress on a suitable supportive base and follow the manufacturer's care instructions.

Regular turning or rotation where required can help natural upholstery settle more evenly, while a suitable mattress protector can help keep the sleeping surface in good condition.

When comparing natural mattresses, consider the spring system, type and quantity of natural fillings, firmness, tufting, edge support and overall construction together.
