Silentnight UltraGel 3000 Mirapocket Box Top Firmer Mattress - UK Small Double

• Pillow top. An additional comfort layer sewn on top, which means a more luxurious, cushioned feel the moment you lie down. It softens the first impression of what is otherwise a firm mattress.
• UltraGel. A gel infused foam layer that adapts to your shape and movements, distributing your weight evenly. According to the listing it's five times more breathable than memory foam, so it should hold less heat.
• Mini Pocket Springs. A layer of 1,000 mini pocket springs that work like bellows, pushing air through the comfort layers as you move. They also help decrease motion transfer, so you feel less of a restless partner.
• Mirapocket Springs. The main support unit of 2,000 Mirapocket springs, zoned so the centre third is firmer. That means greater support under your midsection and encouragement towards better spinal alignment.
