"Designed for cooler, more settled sleep, the DS Living Tranquil Spring Gel Mattress combines supportive springs with a temperature-regulating gel comfort layer. This double mattress (4ft6) is made to deliver dependable, full-body support with a soft to medium firmness that suits everyday comfort. At its core is a 13.5g open coil Bonnell spring system, creating a stable base that helps support you night after night. Above, the gel layer works to dissipate heat to help maintain a cooler sleeping surface, while gently contouring to your body for targeted pressure relief and balanced weight distribution. Finished with a soft quilted panel fabric, the mattress is supported by breathable recycled polyester comfort layers for an added sense of comfort. It is rolled and boxed for easier delivery and setup, making it a practical choice for a wide range of bedroom layouts. Maximum user weight is 120kg.
