The 3500 Sovereign Mattress offers a medium firm feel with an approximate depth of 29cm, delivering a premium sleep experience with noticeable quality from the very first night. Crafted using a high count of individually fabric-encased pocket springs, this mattress features a substantial memory foam comfort layer combined with supportive reflex foam and enhanced edge support, all finished in a quilted cashmere soft-touch knitted fabric padded with polyester for a more plush, cushioned feel. The memory foam gently contours to your body, helping relieve pressure and provide a comfortable, supportive surface, while reflex foam adds responsive rebound to support healthy spinal alignment. The quilted polyester padding creates a smoother, more inviting sleep surface and encourages airflow, helping regulate temperature more effectively than traditional tufted designs. Individually working pocket springs respond to your body weight to target pressure across 7 key areas, supporting back, side, and combination sleepers while absorbing noise and vibration to minimise disturbance from partners or pets. Hypoallergenic and allergen-free, this fire-retardant mattress is manufactured in the UK to meet British safety and quality standards. Single-sided mattress; rotating periodically helps the mattress settle evenly and maintain consistent comfort across the full sleep surface. | Somnior Sovereign 3500 Pressure Relief Cushioned Support Mattress Medium Firm in White | Size: Small Double.
