Source Mattress: Tech Spotlight
THE WONDER OF WOOL
Making a material difference
Crafting an oasis of comfort, using some of Mother Nature’s best ingredients. That’s what we set out to do. Featuring wonderful, natural components like soft, English wool for example (over 7 kgs of it per king size mattress to be precise).
Wool that comes from the gentle climes of Hampshire is very cushiony, very springy - and perfect for mattresses; it’s famed for its qualities of resilience and shape retention, as well as its refreshing breathability.
Those sheep are cleverer than they look.
BODY ALIGNED SUPPORT
CoreMax™ sprung base
Few people know more about springs than our mattress experts. So, when they told us they’d discovered a new, even better sprung base design, we were all ears.
The CoreMax™ base is cleverly designed to provide softness at initial touch, but complete body support when you lie down; each king size mattress features up to 1,000 high carbon steel pocketed springs in seven different zones of firmness to match the needs of the different parts of your body – plus it’s reinforced by a steel frame to minimise roll off at the sides.
The result? Cushioned pressure relief and body aligned support. From side to side, top to bottom.
PATENTED INNOVATION
Signature spring technology
Our patented Aerocoil® springs are central to the award-winning sleep we’re famous for.
There are 1,900 of these titanium alloy micro springs nestling in the upper layers, They work in three, clever ways:
CONTOUR: each small spring compresses, for pressure relief and contoured support
FRESH: they aid the flow of fresh air through the mattress as they compress
CONTROL: their conical shape helps them compress inwards, limiting transfer of movement.
WHERE TECH MEETS TRADITION
Parts handcrafted by experts.
Our Earth mattresses start life on the Hampshire Downs, not in factories. Because that’s the home of the clever sheep who produce that unique Hampshire wool.
The factory where our experienced craftsmen and women work their magic is in Hampshire too. And although we might use high tech machines to give us the precise measurements and weights for every layer, it’s these teams who guide the layers into place, fill and close the mattress - not too tight, not too loose - then tuft and finish each one. It’s a gentle art that requires lots of care and experience to do properly.
EARTH RANGE FEATURES
What’s special about our Earth mattresses?
Why Simba suits everyone
All shapes, sizes & sleep positions
Simba is the most five-star rated mattress brand in the world*. Because our unique Hybrid® mattress technology is designed to feel comfortable to everyone, no matter their shape, size or sleeping style.
It’s about offering improved pressure relief and full body alignment; Simba’s patented, 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® Earth 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.

Aerocoil® springs; 1,900 titanium alloy micro springs (based on king size mattress) manufactured in Leeds, enclosed in polypropylene pockets.
Sprung base: 1,000 high carbon steel barrel springs (based on king size mattress) manufactured in Hampshire and enclosed in polypropylene pockets featuring GRS certified, fire-retardant layer at base.

This mattress has a non-removable cover, so we strongly recommend using a mattress protector to prolong the life of your mattress; the mattress should also be regularly aired, ideally for a few hours a day.
There is no need to turn this mattress, but it will develop natural dips and body impressions so we recommend rotating it head to foot every couple of months for the first 6 months, and twice a year thereafter.
Never use a vacuum cleaner of any kind to clean this mattress, because it may displace the natural fillings. Dust should be removed with a so brush and spillages should be mopped up with a dry cloth; if you need to sponge the mattress, please use a damp cloth and a very mild solution of soap and water. Do not use bleach. -
This Simba mattress comes with a 10-year guarantee, so if it develops a manufacturing fault during that time we’ll exchange it for a new one.

Any other questions?
No matter which of our Earth range you choose, you’re always guaranteed a blend of our patented Simba tech and natural materials – all carefully selected for premium comfort. The difference lies in the layers, their materials and the number of micro springs in each one.
Apart from their varying wool layers each king size Source mattress has eight layers and up to 2,900 springs, each king size Escape has ten layers and up to 4,800 springs, while at the top of our range, and each king size Apex mattress has 12 layers and up to 6,700 springs, with soft cashgora (premium goat’s wool), silk and Hampshire wool for the ultimate sleep.
Each of these mattresses combine natural materials and ingenious tech to support fresher sleep, lasting comfort and a luxurious feel; they’re also designed to be mainly free of glue, facilitating a more efficient recycling process at the end of their life.

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. If you would like our advice, please email us at hello@simbasleep.com.

You’ll be pleased to know the answer is no: you don’t have to turn it, but you do need to rotate it. Think of it as the 'no flipping way'. Rotating your Earth mattress regularly is one of the very few conditions of your 10-year warranty. Take it for a 180 degrees spin often within the first 3 months, then drop down to twice a year for the rest of its life. It’ll help your mattress stay comfortable for longer.
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 us they've suffered from aches and pains and that they feel that their Simba Mattress has helped them to finally achieve a great night’s sleep.
We’ve included innovations like our CoreMax™ Support system to encourage superior support, and natural materials like Hampshire wool to assist pressure relief. You’ll find our most tailored support in the Apex mattress, which has the highest spring count in our whole Earth range. If you think that might be what you're looking for, remember we also offer a 200-night trial, so you can really put your new mattress to the test.
