The secret to a great night's sleep

Natural Vs Synthetic Fibres

Here at Silentnight we use both natural and synthetic materials in our mattresses. When choosing the right mattress and bedding, it is entirely up to personal preference so here are some pointers to set you on track…


Natural fillings such as wool, lead to sturdy fibres that are perfect for a more luxurious feel with natural body and bounce. The secret lies in the crimp:

The fibres have a unique, three dimensional crimp that gives them resilience. These fibres act like millions of tiny springs, helping us move easily and peacefully to sleep through the night.

Crimped wool fibres are naturally elastic, able to stretch and return to their natural shape.

The natural crimp effectively traps pockets of air allowing the fibres to breathe naturally which then creates insulation against the heat as well as the cold.

Wool fibres easily absorb the moisture our bodies generate while we sleep so we don't get that clammy feeling that synthetic fibres sometimes give. Wool can absorb up to 30% of its weight in water without feeling the least bit damp, this is because the molecules in wool are quite porous.

Wool is far more efficient than other textiles at absorbing sweat and releasing it into the air, before bacteria has a chance to develop and produce unpleasant body odour.


Synthetic fibres and fillings are technically advanced materials designed for the modern world and provide sublime comfort and easycare. With all of the benefits of natural fibres, synthetic fibres offers benefits that suit people with hectic schedules and need bedding and mattresses for their on-the-go routine.

Similar to sportswear today, synthetic materials provide high performance, are lightweight and breathable. 

Mattresses are a large investment, so getting the perfect comfort level is crucial. Synthetic fibres allow for customers to select a combined effect of pressure, movement, heat and moisture on various filling materials.

Synthetic fibres in bedding are easily washed, and dry fast keeping sticky fingers and spills at bay.

When selecting the right bedding and mattresses for your family, remember it's down to personal preference. For an added 'luxe' feel, natural fibres may be more desirable, and for easy wash, try synthetic.
