SIGNATURE King Mattress

With 928 heavy-gauge pocket springs, the Signature King has the highest spring count in the range. The result is dense, responsive support beneath a deep pillow top, with room for two to stretch out.

Pillow-top plushness, precision support

• Heavy-gauge 2.15 mm pocket-spring core — Thicker steel wire for a stronger, more resilient base, with every spring individually encased to reduce motion transfer.
• Dual convoluted airflow foam (2 × 3.8 cm) — Egg-crate profiled foam creates channels for air to circulate, spreading pressure across shoulders and hips while helping heat escape.
• Integrated pillow-top comfort system — A deep upper layer delivers that sink-in, hotel-bed feel over a supportive core.
• Quad felt insulation — Four dense 350g felt pads, two above and two below the springs, create a smooth, stable surface and protect the comfort layers.
• Firm-support 24D foam — A firmer foam layer on both faces of the core adds shape retention and helps the mattress hold its comfort for longer.
• Climate-regulating knitted cover — A 320gsm cooling knit on the sleep surface helps draw heat away for a fresher night's sleep.
• Easy to handle — Four side handles for positioning, delivered vacuum-compressed and roll-packed in a wheeled carton.
