Description

The A.H. Beard Domino Oslo Medium King Mattress (DOSLOMMKING) is a premium, Australian-made sleep system engineered to provide a balanced, medium-firm feel that caters to a wide range of sleeping positions. As part of the highly regarded Domino collection—trusted by athletes at the Australian Institute of Sport (AIS)—this king-size mattress ($1830 \text{ mm} \times 2030 \text{ mm}$) is designed to deliver consistent comfort, durable support, and effective climate regulation.

Core Architecture and Support

The foundation of the Oslo Medium is the Conforma Coil pocket spring system. Unlike traditional interconnected springs, this system uses hundreds of individually wrapped coils that function independently. This allows the mattress to respond precisely to the unique contours of the body, providing targeted spinal support from head to toe. By isolating movement to the springs directly under pressure, the system significantly reduces motion transfer, making it an excellent choice for couples who do not want to be disturbed by a partner’s movements during the night.

To ensure the mattress remains stable and supportive to the very edge, it features Performa Edge Support. This high-density foam encasement borders the entire spring unit, preventing border sag and the “roll-off” sensation. This feature effectively expands the usable sleeping surface of the king bed, ensuring consistent support whether you are sleeping in the center or near the perimeter.

Comfort and Climate Control

The “Medium” feel is achieved through a carefully curated selection of high-performance, open-cell comfort foams. These layers provide a gentle, contouring cushioning that relieves pressure on sensitive areas like the hips and shoulders, while still providing the necessary push-back support to keep the spine neutrally aligned.

To regulate sleep temperature, the mattress incorporates Climalux quilting technology in the top panel. This advanced, breathable quilt layer is designed to maximize internal airflow throughout the night, actively dissipating excess body heat and moisture to maintain a balanced microclimate, ensuring you stay cool in summer and comfortable in winter.

Health and Durability

A.H. Beard prioritizes sleep hygiene by incorporating antimicrobial and hypoallergenic treatments into the fabrics of the Oslo. The mattress is endorsed by the National Asthma Council of Australia and carries the Sensitive Choice blue butterfly symbol, indicating that the materials are effective at reducing exposure to common household triggers like dust mites and mold.

Designed for long-term reliability, the Oslo Medium is a single-sided “no-turn” mattress, requiring only periodic rotation to maintain its performance. It is backed by a 10-year manufacturer’s warranty, reflecting the quality and longevity of its Australian construction.
