  • What size is a Simba double mattress?

    Our most popular mattress for double beds is a standard UK double mattress, measuring 135cmW x 190cmL; we also offer longer European Double Mattresses and space-efficient Small-Double Mattresses in our Hybrid® and Pro models. The height of our double mattresses varies according to the design: our Earth range is packed with natural mattress materials and our signature sleep tech, with the Apex design measuring 30cm deep; the luxurious Ultra is the deepest of our Hybrid® mattresses at 34cm deep. If you’d like something roomier, have a look at our King-size Mattresses or our Super King Mattresses. 

    Head over to All Mattresses for more details about our range. 

  • Do Simba also offer mattresses in smaller sizes?

    Yes. We also have a range of super-comfortable Single Mattresses as well as the slightly longer Euro Single Mattresses.

  • What to consider when choosing a double mattress

    It’s a good idea to measure everything out when you buy a double mattress – for example you need to make sure there’ll be enough space to open doors and cupboards. But our double Hybrid® Mattresses are delivered vacuum packed and boxed so you’ll be able to get it up most stairs.

    A double bed mattress is the perfect size for stretching out, without swallowing up the whole room; it’s a great option for growing teens, smaller bedrooms and guests, but might not offer enough space for couples.  

  • Choosing the right Simba double mattress

    Woken up by a fidgety partner? Too hot to sleep? All our double mattresses are engineered to keep you fresh, comfortable and supported, whatever your sleeping style. 

    So what is consistent support? It’s about having exactly the right balance between a top layer that compresses in response to your body, and an underlying layer that gently resists that response. Without the top comfort layer, you’d feel like you were sleeping on a plank, but without the support layer you’d feel like you were sleeping on a trampoline. 

  • Why are the Simba Hybrid® double mattresses unique?

    It’s all down to our award-winning mattress technology. Our Hybrid® double mattress designs are a unique blend of our patented Aerocoil® springs and our Simbatex® foam; together they’re designed to offer contoured support and optimum pressure relief.

  • What’s so special about the Simba Earth range?

    Our double Earth mattresses provide a unique blend of our signature tech with some of Nature’s best materials - for a truly luxurious take on sleep.    

    They all feature a range of hand-tufted layers, including our innovative, sonically welded Quadcore™ base; which helps facilitate a more efficient and complete recycling process.

  • How to care for your double mattress

    There’s no need to turn it over to prolong its life, but we do recommend you rotate your double mattress head to foot once a month for the first three months, and once every three months thereafter. For our double Earth mattresses, twice a year after the first few months will do. This is to keep all the natural mattress fillings more comfortable for longer.  

    Nearly every Simba mattress features a removable cover which you can wash, but we also recommend you get one of our machine washable, quilted cotton Mattress Protectors to help keep your new double mattress fresh and clean. 

  • How long will my double mattress last?

    We’re confident all our Simba mattresses will go the distance, which is why we offer a 10-year guarantee on all new mattresses. Manufacturing faults are rare, but if you stumble across any, just let us know and we’ll replace it with a brand new one.

  • Will my new double mattress qualify for Free Delivery and Returns?

    Yes, even in our double mattress sale periods. Standard delivery is free for all our mattresses to most UK postcodes, with most arriving within 48 hours in non-sale periods. VIP delivery may take up to 10 working days in sale periods. Returns are free too; you have 200 days to decide whether you are happy with your purchase, and if not we’ll collect it from you free of charge. 

  • Can my double mattress be recycled?

    We don’t want any of our mattresses to end up in landfill. Which is why all the double mattresses for sale at Simba are suitable for recycling via our collection service or specialist providers. Those returned in your 200-night trial (or under our 10-year guarantee) are refurbished. And any with too much wear and tear? They’re recycled. Once your mattress reaches the end of its life, we have a specialised Simba Mattress Recycling Service. Simply pay a small fee, and we come and collect it for you. Any brand, any size – no Simba purchase necessary. 

    Find out more about our Mattress Recycling Service. 

  • Can I buy a refurbished Simba double bed mattress?

    Yes, we often have double mattresses available in our Simba Refurbished range. 

    We strive to refurbish or recycle all the mattresses that are returned to us in their trial period; it’s kinder to the planet to give mattresses another life, since we’re keeping them from landfill – and it makes our unique Simba sleep tech more accessible to everyone. Having tested every single component, we replace parts, deep clean and sanitise everything, before a final inspection by our expert renewal team to receive a certified Simba guarantee. 

    The result? You can rest assured our range of Refurbished Mattresses will give you the full Simba experience, at a fraction of the price. 

  • Need a new double bed frame for your mattress?

    We have a range of bed frames to suit every need, from our clutter-clearing Ottoman bed bases to our beautifully simple Wooden beds. And because sleep is personal, you can choose your fabric, headboard design and desired storage on selected premium beds. 

  • Looking for a medium firm double mattress?

    You’re in luck, we rate our Hybrid® double mattresses as medium-firm. But there’s no universal industry system that scores one firm mattress against another, so we’ve designed our mattresses to offer supportive body alignment as well as soothing pressure relief for a medium-firm feel.

Which Simba mattress is best for you?

Here's an introductory guide to our range. If you're not sure which mattress to go for; we have two different ones: the Hybrid® Range and the Earth range. We also have our own range of Simba certified Refurbished Mattresses, subject to availability.

  • Hybrid® Mattresses

    Award-winning mattresses, packed with ground-breaking tech for superb comfort and support. However you sleep, whatever your budget.

  • Earth Mattresses

    Heavenly comfort, sumptuous support. Designed and made in the UK with a luxurious blend of natural materials and our signature technical expertise.
