Oak King Orthopaedic Mattress
The Oak King Mattress is designed to provide reliable, medium-firm support with traditional craftsmanship and durable construction.
With an overall depth of approximately 23cm, this mattress features a robust 12.5 gauge orthopaedic open coil spring unit, offering consistent support across the entire sleeping surface.
Integrated side supports help maximise the usable sleep area while improving edge stability and long-term shape retention.
Comfort & Support
Multiple layers of quality comfort fillings work in harmony with the orthopaedic spring system to deliver a balanced Medium/Firm feel — ideal for those who prefer a supportive yet comfortable sleeping surface.
Durable Traditional Finish
Finished in a premium Damask fabric, the mattress features a classic hand-tufted design. Tufting secures the internal fillings in place, enhancing durability and maintaining even comfort over time.
A vertically stitched border adds further strength to the mattress structure, helping to extend its lifespan.
Practical features include flag-stitched handles for easier turning and built-in air vents to promote airflow, helping regulate temperature and reduce moisture build-up.
