Your concerns about chemicals and plastics in mattresses will probably draw you to natural mattress fillings – materials like wool, cotton, bamboo fibre, and even coconut husk offer an alternative to petrochemical fillings.
Natural fillings offer excellent temperature regulation and wick moisture away from the skin better than synthetic fillings.
There's also a lot to be said about the durability of natural fillings — they don't degrade as fast because no chemical bonds can break (for instance, the wool sewn into a mattress today will be just as good a decade from now).
Join us below for more insight into the advantages of natural mattresses.
Superior temperature regulation
Ever noticed how sheep stay cosy in winter yet don't overheat in summer? That's the magic of wool at work, and it's just as clever in your mattress. The secret lies in its remarkable ability to trap warmth when you're chilly and release it when you're hot.
Cotton plays its part, too, working like thousands of tiny fans to keep air moving through your mattress. But it's bamboo that really surprises most people - this sustainable superstar outdoes even cotton at keeping you at the perfect temperature.
Excellent moisture-wicking properties
The moisture-wicking capabilities of natural mattress fillings make them ideal for comfortable sleep throughout the year.
Wool can absorb up to 30% of its weight in moisture without feeling damp, pulling sweat away from your body while you sleep.
Cotton enhances this effect by allowing air circulation through the mattress layers, ensuring that any absorbed moisture evaporates efficiently.
This natural moisture management system means you're less likely to feel clammy or overheat, and it also reduces the perfect conditions that dust mites and bacteria need.
Superior support and comfort
Natural latex foam – made from rubber tree sap – delivers better support than synthetic foams, including memory foam.
Its resilient structure resists deformation and compression under your body but pushes against it to provide maximum support.
That resilience brings additional benefits, such as fantastic edge support, which allows you to use the entire mattress surface without any ‘rolling-off' sensation.
You should choose natural latex foam for a firm, supportive sleep surface with enough cushioning to ease aches.
Reduced chemical exposure
Natural mattress fillings significantly reduce exposure to synthetic chemicals commonly found in conventional mattresses.
While most modern mattresses contain fire retardants and petrochemical-based foams, natural alternatives use inherently flame-resistant materials like wool, which meets fire safety standards without chemical treatments.
Cotton and bamboo fibres can be processed with minimal chemical intervention, especially when organically sourced.
Enhanced sustainability credentials

The wool in your mattress might come from sheep grazing British hillsides, while the cotton could grow in fields that rotate crops to keep soil healthy. Even coconut husk - a waste product - finds new life supporting your sleep.
The natural beauty lies in what happens years down the line. While synthetic mattresses languish in landfills for generations, natural materials return to the earth without a fuss.
Many manufacturers are catching on, too, partnering with local farmers and embracing sustainable practices that protect the quality of their materials. His Majesty King Charles III headed up the campaign for wool. Wool not only biodegrades in soil, adding nutrients back to the earth, but it also biodegrades in the ocean and water, leaving no impact on the planet's microfibre and plastic pollution.
Superior longevity and durability
When properly cared for, natural mattress fillings often outlast their synthetic counterparts.
Wool maintains its loft and supportive properties for many years without breaking down, while high-quality cotton becomes softer without losing its structural integrity.
The natural resilience of these materials means they can withstand compression and regular use without developing permanent indentations or sagging spots.
Though the initial investment might be higher, the extended lifespan often makes natural filling mattresses more cost-effective in the long run.
Expect to spend around £500 on a double and £600 on a king-size mattress with premium natural fillings like British wool. Sleepeezee, Silentnight, and Relyon are good starting points.
