    Overview

    The Laynee mattress range is designed with a singular purpose—to provide advanced support and exceptional comfort that aligns with your body’s natural posture. Drawing on orthopaedic design principles, Laynee features a two-stage AlignSupport coil system that senses and responds to your unique body shape, helping to maintain spinal alignment through the night.

    At the surface, a SynerFlex comfort layer delivers micro-conformance, easing pressure points and enhancing the overall sleep experience from the moment you lie down. Underneath, intelligently placed touch points engage to provide deeper, tailored support that adapts as you move.

    Comfort is further enhanced with the ComfortCore layer at the centre third of the mattress, made with SenseMaterial to relieve pressure on the lower back—helping you wake up rejuvenated and well-supported. Intelligent SmarTex® fabric also regulates temperature and moisture, creating a consistently comfortable sleep climate throughout the night.

    FlexiCased edge support technology maximises the usable surface of the mattress, allowing you to enjoy stability even at the edges—ideal for adjustable base compatibility and long-term durability. Combined with BasePlank reinforcement, Laynee offers dependable strength and shock absorption.

    From head to toe, Laynee redefines innovation in sleep technology, offering a balanced blend of responsiveness, breathability, and support that keeps your body aligned and your mind refreshed.
