Simba® Mattresses

Who are Simba?

Proudly British and globally renowned, Simba leads the way in sleep technology. Every mattress is developed and manufactured here in the UK, combining innovation with environmentally responsible production. With more five-star reviews than any other mattress brand worldwide, Simba’s reputation for quality and comfort speaks for itself.

What makes a Simba mattress so special?

Simba uses data from millions of sleepers to develop mattress technology that solves real-world sleep problems. The brand’s engineers have developed Simbatex® foam, a breathable alternative to memory foam that helps regulate temperature, while the Aerocoil® spring system provides precise, responsive support.

Each Simba mattress is designed to adapt to your movements, keeping your spine aligned and reducing pressure points. The result is a refreshing, cooler, and more restorative sleep every night.

Every model is crafted with sustainability in mind, made in zero-waste factories from 100% recyclable materials and certified by multiple environmental organisations.

Do Simba mattresses come in a box?

Yes! All Simba mattresses arrive rolled and boxed for easy delivery. Simply unbox and unroll, your mattress will expand to its full shape within a few hours, and reach peak comfort after around 72 hours.

How firm are Simba mattresses?

Simba mattresses are available in medium or medium-firm feels, offering the ideal balance of comfort and support for most sleepers. Thanks to their hybrid construction, Simba mattresses gently cradle your body while maintaining proper spinal alignment, preventing aches and pressure build-up.

The Simba Hybrid Luxe, for example, combines soft upper layers with supportive Aerocoil® micro-springs that precisely target your body’s pressure points.

Can I try a Simba mattress?

Absolutely. We offer 100-night sleep trials across the full Simba range, including the Simba Hybrid® Essential Mattress. Try your mattress at home, and if you’re not completely satisfied, simply return it for a full refund, no fuss.

You can also try out a Simba mattress before you buy in our Kent-based Showroom, where our friendly sleep advisors will be happy to give you personalised advice.

How long do Simba mattresses last?

A Simba mattress typically lasts 8–10 years with proper care. Rotate your mattress every few months to keep the fillings evenly distributed and maintain its original comfort.
