Simba Sleep is one of Britain’s best-known mattress brands, built around a single idea: combine responsive foam with thousands of tiny springs so a single mattress suits a wide range of sleepers. Founded in Bristol and now a certified B Corp, Simba has grown from a one-product bed-in-a-box pioneer into a full sleep range covering mattresses, pillows, duvets and bases. If you are weighing it against other options, our guide on how to choose your mattress walks through the firmness, support and temperature trade-offs that matter most.

Who Is Simba Sleep

Simba launched to challenge the traditional mattress market with direct-to-consumer pricing and a generous home trial. The company designs its products in the UK and manufactures most of them domestically, which appeals to buyers who value shorter, more transparent supply chains. Its B Corp certification reflects commitments to recycling, responsible sourcing and donating mattresses to people in need. The brand is best suited to sleepers who want a balanced, medium-firm hybrid feel with strong cooling credentials, rather than a deep memory-foam hug or a purely sprung bounce.

Technology, trial and availability

Simba’s signature is its hybrid construction. Aerocoil micro pocket springs sit in conical layers that flex independently, contouring to the body while keeping airflow moving through the mattress. Above them, Simbatex foam is infused with graphite to draw heat away from the surface, helping hot sleepers stay comfortable. The result is pressure relief without the trapped warmth that some all-foam beds produce. Simba is actively sold in the United Kingdom and Canada, backed by a 200-night trial in the UK so you can test the mattress at home through every season before committing.

Frequently asked questions

Where are Simba mattresses made?

Simba designs its mattresses in the United Kingdom and manufactures the majority of them domestically. This UK-centred production is part of why the brand can speak confidently about its supply chain and its B Corp commitments. Making most products at home shortens shipping distances, supports local manufacturing, and gives the company tighter control over materials and quality. For buyers who care about provenance and a smaller delivery footprint, the British base is a genuine point of difference compared with brands that import finished mattresses from overseas factories.

What is the Simba home trial?

In the United Kingdom, Simba offers a 200-night home trial. Because a mattress only reveals its true comfort after several weeks of real sleep, this long window lets your body adjust and lets you judge the bed across changing seasons and temperatures. If it is not right for you within the trial period, Simba arranges a return. A trial this length removes much of the risk of buying online without lying on the mattress first, which is one of the main hesitations shoppers have about bed-in-a-box brands.

What makes Simba's hybrid technology different?

Two proprietary elements define the Simba feel. Aerocoil micro pocket springs are small conical coils that compress individually, so the mattress contours closely while still allowing air to circulate and reduce heat build-up. Layered above them, Simbatex foam is infused with graphite to conduct warmth away from the sleeping surface. Together they aim to deliver targeted pressure relief and cooling in one mattress, which is why Simba positions its beds as suitable for couples and for sleepers who tend to overheat on traditional memory foam.

Is Simba available in my country?

Simba is actively sold in the United Kingdom and in Canada through its official channels. The brand withdrew from France and continental Europe around 2022, so shoppers there should look at locally available alternatives instead. If you are in the UK or Canada, you can order directly from Simba and benefit from its home trial and delivery service.

What is a B Corp and does it matter?

A B Corp is a company independently certified for meeting standards of social and environmental performance, accountability and transparency. For Simba, certification reflects commitments such as recycling materials, sourcing responsibly and donating mattresses to those in need. It does not change how a mattress feels, but it gives ethically minded buyers reassurance that the brand is held to verified standards rather than relying on marketing claims alone.
