The Millbrook Baroness Natural Wool Mattress blends traditional British craftsmanship with sustainable, high-quality materials for a naturally comfortable and supportive sleep. With a medium-firm tension, it offers the ideal balance between gentle cushioning and reliable orthopaedic support — perfect for those seeking both comfort and stability.

7-Zone Ergonomic Support for Tailored Comfort

At its core, the Baroness features up to 1000 individually responsive pocket springs (in a king size) arranged in Millbrook’s 7-Zone Ergonomic system. Each zone provides precise support for different areas of the body — softer at the shoulders and firmer through the hips and lower back — promoting natural spinal alignment and reducing pressure points for a healthier, more restful night’s sleep.

Naturally Breathable & Sustainable Materials

Filled with sustainably sourced Hampshire Wool and Fine English Cotton, this mattress celebrates natural luxury and breathability. These premium fibres help regulate temperature and wick away moisture, keeping your sleep environment cool, fresh, and comfortable all night long.

Expertly Crafted for Long-Lasting Quality

Finished with a beautifully woven Damask sleep surface, the Baroness showcases refined design and durability. Millbrook UltraEdge™ reinforcement strengthens the mattress perimeter, providing edge-to-edge stability and maximising sleeping space.

At 25 cm deep and backed by a 10-year warranty, the Millbrook Baroness Natural Wool Mattress is a timeless choice for those who value sustainable comfort, tailored support, and enduring British craftsmanship.
