Materials and Construction

  • The Support Core: Our mattresses utilise high-density reflex foam, which features a unique structure that bounces back into shape instantly. This provides a firm, orthopaedic-style support core that aligns the spine without the need for heavy metal springs.
  • Sustainable Comfort: Our eco foam bunk mattress options use advanced recycled foam technology. This reduced-carbon footprint material offers the same pressure-relieving benefits as traditional foam while being kinder to the planet.
  • Breathable Covers: Each mattress is finished with a soft-touch, breathable fabric cover designed to regulate temperature. This is particularly important for top bunks, where heat tends to rise.
  • Safety Seals: Every product is UK made and rigorously tested. We ensure all materials are OEKO-TEX® certified, meaning they are free from harmful chemicals and safe for sensitive skin.

How to Care for Your Bunk and Trundle Mattress

  • Unpack and Expand: As your trundle bed mattress arrives vacuum-packed, unwrap it in a well-ventilated room and allow it to expand for 24-48 hours.
  • Regular Rotation: While these mattresses are non-turn, you should rotate them from head to toe every month for the first six months to ensure even wear.
  • Use a Protector: To keep your hypoallergenic bunk bed mattress in pristine condition, always use a breathable mattress protector to shield against spills.
  • Spot Cleaning: If stains occur, use a damp cloth with mild detergent; avoid soaking the foam, as moisture can damage the internal structure.
  • Check the Slats: Ensure your bunk or trundle frame has sturdy slats with gaps no wider than 7.5cm to provide consistent support for the foam.
