Soft–Medium
Gently cushioned feel that hugs your shape while still giving supportive lift. Perfect if you prefer a softer mattress but don’t want to sink too deep.

The Derwent 1500 blends cutting-edge comfort with natural luxury. It’s built around a 1500-count pocket spring system that adjusts to your body’s movement, with a plush layer of natural latex for bounce and pressure relief. What sets this mattress apart is the Ultra Edge encapsulated support, giving you full surface comfort without roll-off — even right to the edge.

The top layers are filled with a premium mix of wool, silk, and cashmere (WSC) — all naturally breathable and ideal for regulating body temperature through every season. Designed for those who value softness without sacrificing support, this mattress delivers the feel of luxury night after night.

Best For

• Side and combination sleepers

• People who prefer a softer sleeping surface

• Those looking for natural comfort with premium support

• Anyone who wants full use of the mattress surface with no sagging edges

  What’s Inside

  • 1500 Pocket Springs
    Each spring works independently to respond to your body’s weight and movement. This helps reduce pressure points and gives better spinal alignment. Because the springs aren’t linked together, there’s less motion transfer — ideal if you share your bed.

  • Ultra Edge Foam Encapsulation
    High-density foam borders around the spring unit provide edge-to-edge support, so you can sleep right up to the edge without feeling like you’ll roll off. It also keeps the mattress shape better over time, boosting durability.

  • Natural Latex Layer
    Latex is breathable, bouncy, and long-lasting. It cushions pressure points (like hips and shoulders) while offering gentle push-back support. Unlike memory foam, it doesn’t trap heat or make you feel stuck — ideal for comfort and cooling.

  • Wool Layer
    Naturally insulating and breathable, wool helps regulate body temperature in all seasons. It wicks away moisture and creates a soft, plush surface feel.

  • Silk Layer
    Adds a smooth, luxurious softness and improves airflow through the top comfort layers. Silk is naturally hypoallergenic and enhances the overall feel of the mattress.

  • Cashmere Layer
    A rare, high-end natural fibre that’s incredibly soft and light. Cashmere adds extra comfort and breathability, helping to create that luxury hotel-style sleep experience.

  • Soft-Knit Fabric Cover
    The outer surface is made with a durable, breathable fabric that allows air to circulate while keeping a soft, premium touch against your skin.

Care

• Help It Last Longer
  Regular rotation helps fillings settle evenly — giving your mattress a longer life and better comfort.

• Cleaning Made Easy
  Vacuum the top surface occasionally using an upholstery attachment to keep it fresh and free of dust.

• Use a Mattress Protector
  Essential for hygiene — it shields against moisture, spills, and allergens.
