Breathability & All-Night Cooling: BedStory king mattress features a breathable, skin-friendly cover with a cloud-soft feel, enhanced by an advanced 3D mesh layer for continuous airflow. This intelligent climate-control system ensures a comfortably cool sleeping environment throughout the night, helping you wake up feeling refreshed. Reinforced Edge Support & Motion-Free Sleep: Our dual-edge support system prevents sagging and maintains shape, ideal for sitting on the edge or for those with mobility needs. Combined with high-density individually pocketed springs that contour to your body and absorb movement, it delivers undisturbed sleep whether you rest in the centre or near the edge. Certified Fire Safety & Healthy Materials: Every BedStory mattress is triple-certified for your health and safety: OEKO-TEX, CertiPUR-US, and the rigorous BS 7177 fire retardant standard. This guarantees a sleep environment that is healthy, pollutant-free, and flame-resistant — for your complete peace of mind. Medium-Firm Support & Personalised Comfort: Our king size mattress is designed with balanced medium-firm support to promote natural spinal alignment while adapting to various sleeping positions. We understand every body is unique—allow some time to adjust to your new mattress. If you have any questions, our support team is here to help you settle into restful sleep. Convenient Delivery & Easy Setup: The BedStory 26cm hybrid spring mattress is compressed and vacuum-sealed, neatly rolled and boxed for easy transport. It is compatible with various bed structures including spring bases, slatted frames, and floor platforms. For the best sleep experience, allow 24-72 hours for the mattress to fully expand to its original shape, depending on room temperature and ventilation conditions.
