WHY NOT TRY OUR AWARD-WINNING SLEEP TECH?
The Simba Hybrid® Ultra Mattress has a rating of ["4", "7"], based on 583 reviews.
View ReviewsWe know being too hot stops us sleeping well. That’s why our tech team created
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 structure foam, which is less dense and offers much better, springier elasticity and more
airflow; it’s also infused with graphite, known to dissipate heat for a fresher night's sleep.
Our technologists insisted on 7,300 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.
3,800 titanium alloy Aerocoil® micro springs sit in the upper layers. You won’t be able to feel them, but they compress
individually in response to your body, supporting pressure relief and helping to limit the transfer of movement.
2,500 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
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 about offering improved pressure relief and full body alignment; Simba’s signature tech is designed to create a ‘hugged’, cradled feeling in the upper layers, and more support in the base layers, with adjustment for hips and shoulders.
P.S. We rate our Hybrid® Deluxe mattresses as ‘medium-firm’. There’s no universal firmness rating system in the industry, so we’ve aimed to align our designs with independent studies which show this is ideal for sleep quality and comfort.

The Simba Hybrid® Ultra Mattress
We love our new Hybrid® Ultra Mattress and have both been sleeping like babies for the past couple of weeks. It's comfortable, supportive, but not too hard or too soft. Highly recommended.

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.
