The FusionCool layer, a unique blend of kapok, wool, and bamboo, enhances freshness, while the dual Simbatex foam layers provide luxurious cushioning. The SupportCore base, with 1,000 pocketed springs, offers edge-to-edge support, and the breathable, removable cover with Stratos tech ensures easy care.

Materials
A zip-off Stratos® cool-touch cover tops the FusionCool™ blend of wool, charcoal-infused bamboo and kapok. Beneath sit two graphite-infused Simbatex® layers, a latex and coconut PureLift™ blend, Aerocoil® springs and a CertiPUR® foam base.
Feature or function
Silky-soft cushioning sits at the very top of the Ultra in the FusionCool™ layer, a 250g blend of wool, charcoal-infused bamboo and kapok. Naturally breathable, it lets air flow freely and prevents heat build-up, keeping you cool and dry all night.
Mattress filling
Eleven layers make up the Ultra, with a springy PureLift™ blend of latex and coconut fibre adding elasticity, Aerocoil® micro springs arranged across thirteen supportive zones, and CertiPUR® foam layers giving structure, airflow and a stable base.
Mattress spring count
This mattress features 7,300 springs, including Aerocoil® micro springs for pressure relief and airflow, plus a SupportCore™ base with pocketed barrel springs for edge-to-edge stability and lasting support.
Mattress feature
UK-exclusive HeatRelease™ graphite strips draw excess warmth from your body all night, keeping you up to 4.2°C cooler. Paired with an exclusive double layer of graphite-infused Simbatex® foam, the ideal sleep temperature holds for up to eight hours.
Mattress firmness
Experience the perfect balance of comfort and support with our medium-firm mattress, designed to provide just the right amount of softness while maintaining excellent spinal alignment.
Manufacturer guarantee
10 Years
Please note
Rotate monthly for the first three months, then every three months thereafter. Mattresses are vacuum packed for ease of delivery. 4.2°C based on ISO accredited lab testing of the upper foam layer, with and without HeatRelease™.
Firmness
Medium/Firm
Care
