SimbaHybrid® Ultra Mattress, Medium/Firm Tension, King Size

The Simba Hybrid Ultra mattress is designed with 11 layers of high-performance natural materials and the most advanced, signature Simba technology yet. The result is a mattress that offers luxurious, cushioning comfort and tailored pressure relief. It has a medium-to-firm mattress tension rating.

Our highest spring count ever
With over 7,000 Aerocoil® springs, this mattress contours each body. Made from titanium alloy, each spring individually compresses and responds to your body weight and shape, creating different zones of support where you need it most. There’s also additional layers of micro springs that push cool and fresh air through the mattress as they compress, while also helping to limit the transfer of movement.

Edge-to-edge support
There’s support throughout this mattress thanks to Simba’s SupportCore™ base. 1,000 pocketed barrel springs help to limit roll-off at the sides so you feel supported from one end of this mattress to the other.

Simbatex ® foam
With an open structure to encourage airflow, there’s two layers of Simbatex ® foam in this mattress. They’re infused with graphite, which is renowned for its heat dissipation properties and they provide cushioning comfort while helping to keep you cool.

Purelift™ flexible support layer
PureLift™ is a fusion of elastic latex and breathable coconut fibres, both known for their properties of resistance and bounce. In product testing, this unique blend created an incredible spring-like layer with superb airflow and pressure distribution, designed to adapt to your body shape to provide enhanced and complete support.

FusionCool® top layer
To create the most comfortable top layer for the Ultra mattress, Simba have combined breathable wool, airy bamboo and charcoal. But the addition of silky-soft kapok, found in the rainforests of South East Asia offers an innovative twist to ensure you stay fresh and dry. Kapok has an air content of 80% and a fine wax coating that makes it moisture-resistant and highly breathable, so the mattress feels more airy and cool.

HeatRelease™ technology
Stay up to 4.2°C cooler (i) with Simba's UK-exclusive HeatRelease™ technology. Engineered with heat-absorbing graphite, these strips are proven to draw excess warmth away from your body as you sleep, starting within 20 minutes and actively working all night long. Together with Simba's graphite-infused Simbatex® foam, they keep you at the ideal sleep temperature for up to 8 hours (ii).

(i) Under testing in controlled laboratory conditions, the upper foam layer of a Simba Hybrid® Ultra mattress was found to be 4.4°C degrees lower with the HeatRelease™ technology than without.

(ii) Up to 8 hours based on controlled laboratory testing; individual experience may vary.

Soft, breathable cover
The soft, knitted top layer of this mattress zips off easily so you can remove it, wash it and replace it to keep your sleep space clean. It’s enhanced with 'cool-touch' Stratos® technology for freshness and acts as a protective shield for the inner layers of the mattress.

Proudly made in the UK
Made in Manchester, with titanium alloy micro springs from Leeds and airy foam layers from Middleton.
