Upgrade your sleep with the Clusterfull Mattress Topper in Super King sizeβ€”a breathable, cloud-soft layer that elevates your existing mattress with targeted support, loft, and plush comfort. Each pocket is a carefully engineered cassette, generously packed with 100% Smartfil fibres to deliver consistent, responsive lift where you need it most.

Why this topper stands apart

  • Innovative cassette construction = independent pockets that keep the fibres evenly distributed, preventing sagging and ensuring stable support all night long.
  • Deeply-filled pockets = a balanced blend of loft and resilience, so your hips and shoulders settle into a supportive, yet soft embrace without flattening.
  • 100% Smartfil fibres = a breathable, durable fill that maintains loft and comfort wash after wash (without compromising the topper’s structure).
  • 100% cotton cover = a light, breathable layer that wicks moisture and stays cool, helping you sleep more comfortably across seasons.
  • Seasonless comfort = the combination of breathable cotton and resilient fill keeps you comfortable whether it’s warm or cool outside.

Who is it ideal for?

  • Sleepers seeking targeted, point-pressure relief on a larger bed, especially those who move during the night and need consistent support across the mattress surface.
  • Couples who want independent support characteristics with a breathable top layer, helping reduce motion transfer while maintaining a plush feel.
  • Anyone upgrading an older mattress who wants a noticeable boost in loft, support, and overall comfort without a full replacement.

How it helps you rest better

  • Enhanced spinal alignment and pressure-point relief due to individually cushioned cassette pockets that adapt to your body’s contours.
  • A breathable, cotton cover that stays cooler for longer, promoting a more refreshing night’s sleep.
  • A durable fill that resists permanent compression, so you wake up with a more even, supported feel across the bed.

Care and maintenance

For localised soiling, use a damp sponge to lift stains. Do not machine wash, bleach, dry clean, or tumble dry. Following these care guidelines helps preserve the topper’s structure and long-lasting comfort.

Transform your sleep surface with the Clusterfull Mattress Topperβ€”Super King sizeβ€”and experience deeper rest, improved comfort, and a cooler, more breathable night’s sleep.
