    Overview

    The Posture Premier mattress range is designed to deliver an enhanced sleep experience through a thoughtful combination of reliable support and advanced comfort materials. Created to suit a wide variety of sleepers, this range balances everyday durability with a more refined level of comfort, making it ideal for both primary bedrooms and guest spaces.

    At the foundation of the Posture Premier range is a 5-turn PostureTech coil system, engineered to provide deep-down support and promote correct spinal alignment. This responsive support system adapts to body movement throughout the night, helping to minimise disturbances and maintain consistent comfort from edge to edge. Paired with high-quality pressure-relieving comfort layers, the mattress works to reduce pressure points and encourage a more restful, uninterrupted sleep.

    EdgeGuard support reinforces the full perimeter of the mattress, maximising the usable sleep surface while delivering a stable seating edge. This added durability ensures long-term performance and enhances everyday practicality, whether sitting, sleeping, or moving across the bed.

    Finished with antibacterial fabric and a clean, modern design, the Posture Premier range is built for both comfort and hygiene. It offers a versatile sleep solution that caters to different comfort preferences while maintaining consistent support across all sizes. With a focus on balanced performance and dependable quality, the Posture Premier range is designed to help sleepers wake feeling refreshed and ready for the day.

    Care Instructions
    Remove the mattress from its packaging and allow it to air out. This helps any new mattress scent to dissipate. Rotate your mattress regularly to ensure an even amount of wear across the sleep surface. Turn the mattress by 180 degrees, but do not flip it over. First 3 months — rotate every 2 weeks Continue to rotate once every 3 months
