The Arthur Sleep Cool Rock Hybrid Mattress is designed to deliver extra firm, orthopaedic support with advanced cooling comfort. Part of the Arthur Sleep Cool Arthur range, it combines pocket springs, gel-infused foam, and body-contouring layers to promote healthier sleep and long-lasting performance.
Featuring a combination of pocket springs and supportive foam layers, this hybrid mattress provides targeted support across the body. The orthopaedic design helps maintain proper spinal alignment, making it ideal for those who need enhanced back support.
The cool gel-infused foam layer helps regulate body temperature and reduce heat build-up. This ensures a cooler, more comfortable sleep — particularly beneficial for warm sleepers.
With an extra firm tension, the mattress delivers a stable, supportive feel while still offering body-contouring pressure relief. It supports key areas such as the back, shoulders, and hips for a more balanced sleep posture.
A blend of soft foam layers and a quilted fabric cover enhances comfort while maintaining breathability. The hypoallergenic construction helps create a cleaner, fresher sleep environment.
The mattress is vacuum packed and rolled for easy transport and setup. Simply unroll and allow it to expand to its full shape.
