How firm is the Original mattress?
The Simba Hybrid™ Original mattress has a medium-plush feel, providing a perfect balance of comfort and support.
We've built 100's of prototypes which confirmed that the mattress design that suits the most sleepers is a hybrid - but not just any hybrid. We're confident ours are perfect for 95% of sleepers, we also have thousands of happy sleepers who say the same here.
If you prefer a softer or firmer mattress, consider our Hybrid™ Essential or Hybrid™ Pro models.

What's the difference between your mattresses?
No matter which of our three Hybrid™ Mattresses you choose, you're always guaranteed our patented blend of cooling foam and ultra responsive Aerocoil® springs.
The difference lies in the layers and the number of springs in each:
The Hybrid™ Essential Mattress has four comfort layers and up to 1,500 springs and is designed for those who are looking for a medium firm feel.
The Hybrid™ Original Mattress, offering a medium plush feel, has 5 comfort layers and up to 2,500 springs.
The Hybrid™ Pro Mattress has seven layers and up to 5,000 springs and offers our plushest feel thanks to an extra layer of Aerocoil® micro springs and a blended wool layer. Added springs and layers provide a plusher, more luxurious feel, even better heat regulation and ultimately an even more comfy night's sleep.
What base can I use for my Simba Hybrid™ Mattresses?
These are some of the common bases used with our mattresses:
Platform top (flat top, can include divans)
Slats (evenly spaced boards)
Sprung divan or box spring (frame with springs set in)
Any supportive bed base — including adjustable — is suitable, as long as that's its dedicated purpose. The Hybrid™ Mattress is at its best on a sprung or rigid divan or slatted bed frame.
If you have a slatted base, quickly whip out the tape measure to check the slats aren't more than three inches apart.
Will I need to turn my Simba Hybrid™ Original mattress?
Think of it as the 'no flipping way'. You don't have to turn it (phew), but rotating your mattress regularly is one of the very few conditions of your 10-year warranty. Take it for a 180 degrees spin on the base once a month for the first 3 months, then every 3 months for the rest of its life.
How firm are the Simba Hybrid™ Mattresses?
Our mattresses vary from medium firm to plush. The Hybrid™ Essential Mattress is for those who are looking for a medium firm feel, whilst the Hybrid™ Original Mattress offers a medium plush feel. Pick the Hybrid™ Pro Mattress if you are after a plush feel.
I have back problems. Will this work for me?
We're not medical professionals, and we can't judge what's right for your back.
All we can say is that we've received huge amounts of positive feedback from sleepers who tell they've suffered from aches and pains and that they feel that their Hybrid™ Mattresses have helped them to finally achieve a great night's sleep.
One of the innovations that we've included is our super light comfort spring layer. Our springs are lighter and finer than traditional chunky bedsprings, so you won't get that poking-in feeling. And they're made to a patented, cone-shaped design which hugs every point of the body and pivots and flexes to distribute your weight fully for pressure relief.
