WHY NOT TRY OUR AWARD-WINNING SLEEP TECH?
The Simba Hybrid® Ultra Mattress has a rating of ["4", "7"], based on 415 reviews.
View Reviews & 5 AwardsOur dream mattress. A luxurious cocooning fusion. Thirteen layers of remarkable natural materials and our signature tech.
We know being too hot stops us sleeping well. That’s why our tech team created cooling,
cushioning Simbatex® foam in the first place. But the Ultra is the only Simba mattress to have a revolutionary,
double layer of it.
Simbatex is an open-cell foam, with a less dense structure that offers much better, springier elasticity and more
airflow; it’s also infused with graphite, a natural heat conductor which helps excess warmth and humidity flow away
from the body.
Our technologists insisted on 8,500 springs in the Ultra, more than any other Simba
mattress. They said it was the path to perfection, and we couldn’t argue with that.
4,000 titanium alloy Aerocoil® micro springs sit in the upper layers. You can’t feel them, but they compress
individually in response to your body, providing ergonomic pressure relief and limiting transfer of movement.
3,500 high carbon steel Aerocoil® micro springs sit further down the mattress to maximise support, gently
pushing fresh air through the mattress as they compress.
The Hybrid® Ultra also features our SupportCore™ base, with 1,000 pocketed barrel springs to ensure 100%
edge-to-edge support.
Why Simba suits everyone
Simba is the most five-star rated mattress brand in the world. Because our unique Hybrid® mattress technology is designed to feel perfectly comfortable to everyone, no matter their shape or sleeping style.
It’s a balance between providing ergonomic pressure relief for your body, and correct alignment for your spine; Simba’s signature tech ensures a ‘hugged’, cradled feeling in the upper layers, and perfect spinal support in the base layers, with adjustment for hips and shoulders.
P.S. We rate our Hybrid mattresses as ‘medium-firm’. There’s no universal firmness rating system in the industry, so we’ve based our design on independent studies that show this is best for sleep quality and comfort.
The Simba Hybrid® Ultra Mattress is 34cm deep and includes 8 carry handles (Single size has 4).
Top cover: 500g knitted top cover (due to range consolidation fabric spec may vary slightly between 02/24 and 07/24) with zip-off, washable sleep surface, replacement covers available to purchase.

We strive to continuously improve in all areas, and a review left for Simba by a customer necessarily relates to the products and/or services which were delivered to that customer at a particular point in time.
All our Simba beds are designed to match perfectly with your Deluxe mattress. Here are a few of our most
popular:
Slats
(evenly spaced boards)
Sprung divan or box spring
(frame with springs set in)
The Deluxe range features our best signature Hybrid® tech; a damaged bed
could impact its performance. We suggest trying a supportive bed base – like one of our Ottoman, Divan, Wooden
or Upholstered models – for maximum support.
If you have a slatted base, quickly whip out the tape measure to check the slats aren't more than three
inches apart. And if they are, a baseboard will help.

Up to 2,500 Aerocoil® springs for no-pressure support
Super soft and breathable sleep surface
Two spring-comfort layers for advanced comfort and airflow
Up to 5,000 Aerocoil® springs for gravity-defying support
