2Organic cotton.

Sustainably Produced Organic Cotton

Cotton is renowned for its breathability, cooling properties, and durability, making it an excellent choice for mattress covers. However, the conventional cultivation of cotton can have adverse environmental impacts.

Addressing this issue, we've opted for 100% organic cotton for the Simba Green's cover. The production process of this cotton ensures the safe harvest of raw materials and responsible manufacturing practices. It’s cultivated without harmful chemicals, further lessening its environmental footprint.

Moreover, our organic cotton undergoes natural bleaching and a botanical fire-retardant treatment. This makes it not only an environmentally responsible choice but also the best quality cotton we can source.

As far as eco-friendly materials go, you won't find anything better.

3 Core comfort; the
Aerocoil® spring

Patented sleep engineering

Our patented micro springs are so strong that they offer unrivaled support, but also so small that we can position them unnoticed nearer the top of the mattress, where they limit motion transfer and help prevent overheating.

They are up to 5,000 of these steely, recyclable gems in the Simba Green, tucked under the latex layer where they offer increased air circulation and ultra-responsive comfort - flexing gently in response to you and your partner's every move, offering personalised support to one without disturbing the other.

4 Going
full circle...

Use. Recycle. Repeat.

All Simba mattresses are designed with the future of our planet in mind, being 100% recyclable and aiding in the reduction of waste heading to landfill. Our Simba Green mattress further pushes this commitment to sustainability, crafted with careful consideration to be effortlessly disassembled and recycled. We've consciously decided against using chemical glue in this model, as it can pose potential harm to the environment and hinder the recycling process.

We are not only dedicated to creating sustainable products, but also ensuring that each component maintains superior quality and durability. While we use recycled materials in our mattresses, we balance this with new fibers to guarantee the longevity of your sleep surface.

This commitment reflects our pledge to play our part in the circular economy, emphasizing a future where resources are not merely consumed, but continually reused. It’s our stride towards being not just a part of the bedding industry, but a part of the solution.


Unrivalled support and airflow

Our Supportcore™ base features up to 1,000 pocketed springs, but by varying the diameter of the spring wire we’ve been able to create 5 support zones for the parts of your body with more specific needs, such as your shoulders and hips. The same technology allows effective edge-to-edge support, thanks to firmer rows of springs at the edges of the mattress.

Using a spring base rather than foam also encourages even more airflow through the mattress. But what makes this pocket spring base so unique, and so Simba, is its sustainability factor: it’s 100% recyclable because there’s nothing in it apart from steel and recycled fibres. But we’re even more proud that it’s the only pocket sprung base that can be rolled and boxed, which makes this mattress more efficient to transport and reducing its carbon footprint.

For a smaller footprint

It’s not just about what materials we use. It’s how we put them together. Because to produce a luxury, more eco-friendly mattress like this requires skill, a keen eye, and meticulous attention to detail.

That’s why we’ve chosen to have it hand stitched, by experienced craftspeople. It’s a cleaner, more sustainable way to guarantee a quality mattress, and a key factor in a carbon footprint that’s just half that of traditional Hybrid mattresses.
