High Density Foam Mattress Breathable Mesh Sides, Soft-Knit Cover & Support Foam Base Rolled & Boxed - King-Size (W150cm x L200cm x D24cm)

Upgrade your sleep with the Sliding Wardrobes 4U Smart High Density Foam Mattress – combining firm 30D support, breathable comfort, and long-lasting durability. Perfect for bedrooms, guest rooms, or children’s spaces, it delivers optimal spinal alignment, targeted pressure relief, and a consistently supportive feel for truly restorative rest.

Built with a premium 30D high-density hard foam core, this mattress offers unyielding support that resists sagging, keeping your back aligned all night. The multi-layer design adapts to your body’s contours, reducing pressure on shoulders, hips, and back, helping to minimise tossing and turning. Despite its firm feel, it provides gentle contouring for a balanced, comfortable sleep experience.

The breathable design keeps you cool and fresh. Sandwich mesh fabric sides promote airflow, while the soft, skin-friendly knitted fabric top adds a luxurious touch. Elegant blue piping gives it a modern look, and the durable linen anti-slip base ensures your mattress stays securely in place on any bed frame.

Convenience is built in – the mattress arrives vacuum-packed and rolled in a compact box for easy transport and setup. Simply unbox, unwrap, and watch it expand to full size within minutes.
