Sian Elite PRO PLUS+

The Sian Elite PRO PLUS+ is the most substantial mattress in the Sian collection, and the one to choose if you sleep warm. Its comfort surface is a premium-grade gel-infused open-cell foam: the open structure lets air pass through the foam rather than trapping it, so heat and moisture disperse instead of gathering around you as the night goes on.

Beneath that sits a multi-layered support system. A dynamic support layer steadies the lower back, shoulders and hips, while a high-resilience Reflex foam base holds the whole mattress in shape and keeps the upper layers performing as they should. The feel is medium-to-firm — a surface that yields, but not far. Everything is encased in the SmartTech 3D Airflow cover, woven with cool-to-touch performance fibres and made to unzip so it can be taken off and freshened.

Each one is built to order in the size you configure, by hand, in the same way as the rest of the collection.

• Gel-infused open-cell foam that moves air instead of holding heat
• Medium-to-firm feel rated 8/10 for those who want a structured surface
• Reflex foam base for shape and support that lasts
• Zip-off cover with cool-to-touch performance fibres
• A deep profile that gives the bed real presence
