Silentnight Plant Based 1200 Mattress - UK Super King

• Breathable Tencel™ Lyocell sleep surface. A silky, soft touch fabric woven to allow airflow and move moisture away from you as you sleep, which means the surface feels naturally cool rather than clammy. A helpful start if you tend to overheat at night.
• Platinum comfort layer. Silentnight describes this as ten times more breathable than memory foam while offering the same pressure relief. In practice that means a cocooning, cushioned feel without the heat build-up memory foam is known for.
• Plant Based Comfort Layer. A blend of bamboo, kapok, flax and aloe vera, sustainably sourced and designed using Silentnight's sleep research. This is where the mattress gets its natural credentials, replacing synthetic fillings with plant fibres.
• 1200 Mirapocket® springs. The 1200 individually pocketed Mirapocket springs respond to your body independently, which means better spinal alignment and less disturbance from a partner's movement.
