King-Size Natural Mattresses

Sink into one of our king-size natural mattresses. They’re made from materials such as cotton, silk and lambswool for enhanced comfort and breathability. Insulation pads provide extra support, while high spring counts ensure firmness through the night. Look out for our ActiPro covers, which have anti-allergy, anti-bacterial and anti-odour properties. Our nominated-day delivery service makes furniture shopping simple
