The Harrison Spinks Bronze Ortho 3500 Mattress is a premium orthopaedic sleep solution designed to deliver firm, supportive comfort with minimal maintenance. Part of the Turn Free collection, this mattress is handcrafted in Yorkshire using traditional techniques and responsibly sourced natural materials. The Bronze Ortho 3500 is ideal for sleepers who prefer a firmer feel while still enjoying the benefits of advanced spring technology and breathable natural fillings.

At the core of the mattress is a sophisticated spring system engineered to provide dependable support and long-term performance. The Bronze Ortho 3500 features 3500 springs in a king size mattress, combining the innovative Cortec™ Quad Revolution® pocket spring system with contouring HD Micro Springs. The Cortec™ spring system uses a glue-free design that allows each individual spring to move independently, helping the mattress respond accurately to body weight and shape while reducing motion transfer. This makes it particularly well suited to those who require consistent orthopaedic support throughout the night.

Working above the core spring unit are HD Micro Springs, which sit closer to the surface to enhance responsiveness and pressure relief. These high-density springs add an extra layer of tailored comfort while supporting correct spinal alignment. Together, the spring layers create a stable, firm sleeping surface that supports the body evenly from head to toe, helping reduce pressure build-up and unnecessary movement during sleep.

Comfort is further enhanced by a carefully selected blend of natural fillings. Layers of British wool and viscose provide a breathable, moisture-regulating surface that helps maintain a comfortable sleeping temperature. This is complemented by a cotton, hemp and flax blend, which adds softness while improving airflow and moisture control. Homegrown hemp is also included, valued for its durability, breathability and natural resistance to bacteria. A layer of Sustainable Ecotex adds resilience and helps the mattress retain its shape and supportive qualities over time.

The Bronze Ortho 3500 Mattress is finished with an in-house woven cover that is free from FR chemical treatments, relying instead on the natural fire-retardant properties of wool. Two rows of hand side stitching reinforce the mattress borders, improving edge-to-edge support and helping to prevent bulging while securing the internal layers in place.

Designed for ease of care, this is a turn-free mattress, meaning there is no need to flip it. Simply rotate the mattress from head to toe on a regular basis to maintain comfort and extend its lifespan. With its firm orthopaedic feel, natural fillings and advanced spring technology, the Harrison Spinks Bronze Ortho 3500 Mattress is an excellent choice for sleepers seeking supportive, low-maintenance luxury backed by traditional British craftsmanship.
