Stay Cool at Night - thanks to 7.5 tog moisture-wicking hollowfibre

Hollowfibre filling draws moisture away from the body while promoting airflow through the lofted fibres, helping to regulate temperature. A soft microfibre outer layer complements the fill by allowing heat to escape and skin to breathe.

Reduced night-time sweating and a fresher feel through the night, ideal for humid evenings. Sleep remains more comfortable without the weight of winter bedding.

Allergy-Friendly Sleep - with non-allergenic hollowfibre filling

Filling is specified as non-allergenic and free from materials likely to trigger common allergic reactions. Construction avoids common natural allergens that can cling to fibres.

Clearer breathing and fewer symptoms such as sneezing or itching for those sensitive to allergens. Well suited to allergy-prone bedrooms and guest beds.

Quick, Practical Care - with a machine-washable microfibre cover

Designed for machine washing at 40°C and safe for tumble drying, allowing regular cleaning without specialist care. UK manufacture includes a two-year quality guarantee to support durability.

Rapid turnaround after washing keeps spare bedding ready for guests and trips. Long-term performance is easier to maintain with straightforward home laundering.
