Silentnight Plant Based Box Top 1800 Mattress - UK Double

• Tencel™ Lyocell sleep surface. A silky, soft touch top layer woven to allow airflow and carry moisture away from you as you sleep. In practice, that means a cooler, drier feel through the night.
• Platinum comfort layer. Silentnight says this layer is ten times more breathable than memory foam while offering the same pressure relief. You get that cocooning, contouring feel with less of the heat build-up memory foam is known for.
• Plant Based Comfort Layer. A cushioning layer made from a combination of bamboo, kapok, flax and aloe vera, which Silentnight says is sustainably sourced. This is where the mattress gets its plant based name and much of its soft, breathable character.
• Mirapocket® springs and mini springs. 800 Mirapocket springs adjust to your movements through the night, combined with 1000 mini springs for extra comfort and breathability. Each spring works independently, which means better isolation of movement between you and a partner.
