Layer Details
UltraGel comfort layer
A gel-infused foam layer that Silentnight says responds to your movements. In practice, that means it should adjust as you shift position, so you can toss and turn without feeling stuck in one spot.
Mirapocket and mini springs
This layer combines 2000 Mirapocket springs with 1000 mini springs, giving zoned support. The idea is that different areas of your body get the support they need, which helps balance the soft top with a more stable base.
Layer details from silentnight.co.uk product page, October 2026.
