Spring King Madrid 1000 Pocket Mattress - UK Small Single

• Cover. A breathable Belgian damask fabric cover, which means air can move through the sleep surface rather than trapping warmth against you. It's a traditional, hard-wearing choice.
• Comfort Fillings. Soft white fibre fillings made from 100% polyester. These give a gentle cushioned feel over the springs, though they're simpler than the foam layers found on pricier mattresses.
• Support System. 1,000 individually pocketed springs, each mounted in its own separate fabric pocket so they work completely independently of one another. In practice, that means support follows your body's contours and your partner's movements are less noticeable.
