Source Mattress: Tech Spotlight

EARTH MATTRESS RANGE

This is Planet Earth…

We live in a wonderful world, full of remarkable natural materials. And we’ve incorporated a whole range of them in our Source mattress, teamed up with the latest tech. For better sleep, naturally.

COTTON, HEMP & FLAX

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 cushiony, natural components - like the cotton, hemp and flax we use in the Source mattress.

Take cotton for example. It might be a familiar classic, but our technologists tell us those soft, fluffy cotton fibres are famous for their springiness and airflow enhancing properties – so we thought they’d make an ideal combination for a comfortable night’s sleep.

The cotton we use is upcycled from traditional French mills. But we’ve blended it with home grown hemp and flax, from lush Yorkshire meadows; these two plants have been prized for centuries for their resilience and longevity, and thanks to them we believe your mattress will feel as comfortable at the end of its life as it does at the beginning.

GROUND-BREAKING SPRING TECHNOLOGY

QuadCore™ spring base

Few people know more about springs than our mattress engineers. So when they told us they’d created a new, even better design, we were all ears.

Usually mattress springs are connected to each other in rows or large groups. So any movement one spring makes is passed on to the next, and the next after that. Across the entire mattress. But our clever QuadCore™ springs are grouped just four at a time, disrupting any ripple effect and limiting motion transfer to encourage more tailored, accurate support.

But that’s not all. Fixing springs with glue can damage them and inhibit movement, so the team were excited to discover another way of connecting them: sonic welding. It sounds cool, and it is – this way the springs themselves remain untouched, undamaged and free to move individually.

PATENTED INNOVATION

Along with the 750 Quadcore™ springs, all our Earth mattresses feature a layer of our patented Aerocoil® springs; they’re central to the award-winning sleep we’re famous for.

There are 2,500 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 

Hand tufted with care. 

Our Earth mattresses start life on a Yorkshire farm, not a factory. Because that's where many of the crops and materials we use are grown, harvested, and processed.

And the factory where our experienced craftsmen and women set to work is in Yorkshire too – we call it our county of comfort. And although we might use high-tech machines to give us the precise measurements and weights for every layer, it’s these highly skilled teams that stitch and tuft the layers, feeling the mattress, checking the stitching. The way it’s been done for centuries.

An exceptional craft, for an exceptional mattress.

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.
