Description

The Millbrook Sovereign Natural Pillow Top Mattress represents the pinnacle of handcrafted British luxury. Combining natural indulgence with precision-engineered support, it offers a sumptuously soft yet supportive feel — the ultimate choice for those who desire truly restful, restorative sleep.

Tailored 7-Zone Ergonomic Support

At the heart of the Sovereign lies Millbrook’s 7-Zone Ergonomic Pocket Spring System, featuring up to 1000 individually responsive springs (in a king size). Each spring works independently to contour perfectly to your body, offering softer comfort at the shoulders and firmer support through the hips and lower back for improved posture and pressure relief.

Naturally Luxurious Fillings

Expertly layered with Hampshire Wool, Natural Silk, Cashgora, and Fine English Cotton, the Sovereign delivers unparalleled comfort, breathability, and moisture control. These premium natural fibres work in harmony to regulate temperature and maintain a fresh, comfortable sleep surface throughout the night.

Sumptuous Pillow Top Comfort

A hand-tufted Damask pillow top crowns the mattress, adding a layer of plush, cloud-like softness without compromising on support. Beneath, Millbrook UltraEdge™ reinforcement ensures consistent, edge-to-edge stability — maximising sleeping space and maintaining the mattress’s elegant shape over time.

Expert Craftsmanship and Lasting Quality

Practical details such as air vents and turning handles showcase Millbrook’s thoughtful design, promoting airflow and making rotation simple. With a no-turn design for easy care, the Sovereign remains supportive and comfortable with minimal maintenance.

At 31cm deep and backed by a 10-year warranty, the Millbrook Sovereign Natural Pillow Top Mattress stands as a true statement of sustainable luxury, combining the finest natural materials, handcrafted precision, and indulgent comfort worthy of its royal name.

Cashgora

Generous amounts of Cashgora fibre offer sumptuous levels of comfort. This works with your body temperature to keep you cool in the summer and warm in the winter.

Natural Silk Layer

Renowned for its exquisite softness and lightweight feel, this luxurious natural silk layer adds an unparalleled touch of elegance and comfort, ensuring a truly indulgent sleeping experience.

Sustainably Sourced Hampshire Wool

Cosy and cushioning, Hampshire wool is known for its durability and elasticity, making it the perfect material for adding extra comfort to your mattress. Plus, you can sleep even easier knowing it's sustainably sourced.

Fine English Cotton
