  • What size is Simba’s Super King Mattress?

    The Simba super king bed mattress is the largest mattress we offer, and it fits all standard UK Super King beds, measuring 180cmW x 200cmL. The depth of your super king mattress will vary according to the type of mattress you select; for example, our Earth range is packed with natural mattress materials and our signature sleep tech, with our Apex model measuring 30cm deep; our Deluxe range has the Hybrid® Luxe, which comes in at 31cm, and the Hybrid® Ultra, our deepest mattress at 34cm. But our Comfort range has a smaller depth, with our Hybrid® Essential just 20cm deep – so please check the details on each product page before buying.  

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

  • Why choose a Simba Hybrid® super king mattress?

    Want to buy a Super King Size Mattress but not sure what’s so special about a Simba Hybrid®? It’s all about the innovative, signature sleep technology we’ve designed, and the balance of support and comfort it creates. Take our cone-shaped Aerocoil® micro springs: they’re engineered to offer better spinal alignment and increase air circulation through the mattress, while our Simbatex® foam is designed to keep your whole body feeling fresher and more comfortable. That goes for both our wallet-friendly Comfort range, and our luxurious Deluxe range.

  • What makes Simba Earth super king mattresses so special?

    The Simba Earth Super king size mattresses are in a class of their own– featuring a unique blend of our signature tech with some of Nature’s best materials for a truly luxurious sleep.    

    They all feature a range of hand-tufted layers, including our innovative, sonically welded Quadcore™ base.

  • Find out which Simba super king size mattresses we recommend for common sleep issues:

  • Are Simba’s super king bed mattresses designed for a specific sleeping position?

    Whether you sleep on your back, side or front, our Hybrid® super king mattresses are designed to offer excellent support for all sleeping styles; the combination of our patented Aerocoil® micro springs with pressure relieving Simbatex® is a winner. 

    Recommended super king-size mattress: any Hybrid® Super King Mattress

  • Which is Simba’s best super king mattress for couples?

    Sharing a bed can cause two common sleep issues: being woken by your partner’s tossing and turning, and being more likely to overheat. 

    But Simba’s innovative Aerocoil® springs are designed to offer tailored support for each partner, limiting motion transfer from one person to another. Their unique conical design means they compress inwards rather than sideways. Strong but small, they’re able to nestle unnoticed at the upper surface of your super king mattress where they help with increased airflow through the mattress. So we suggest going for a mattress with more in, like those in our Deluxe range

    Recommended Super King Mattress: Any of our super king mattresses that feature our patented Aerocoil® springs; opt for the highest number of springs you can afford for the most tailored support – like our Hybrid® Ultra. 

  • Which of Simba’s super king size mattresses is best for heat control?

    Did you know your body temperature drops a few degrees when you sleep? So if you’re too warm in a bed where that natural process is halted, and you might find it harder to sleep. 

    That’s why all our super king Hybrid® mattresses are designed to help keep you cool, from our Comfort range to our Deluxe mattresses. It’s thanks to our Aerocoil® springs, which help push air gently through the top layers, and the Simbatex® foam in our Hybrid® mattresses. Our Earth range also has natural mattress materials to help you stay fresh and comfortable throughout the night. 

    Recommended Super King Mattress: All our hybrid super king mattresses are designed for cooler sleep, but any mattress from our Earth range (whether that’s Source, Escape or Apex) are help you stay fresher more naturally. 

  • Which of Simba’s super king size mattress is best for back pain?

    Poor alignment of the spine or inadequate body support may cause debilitating aches and pains. But we’re not medical professionals, so we can’t judge what’s right for your back. What we can say is that we’ve received huge amounts of positive feedback from people who say they’ve suffered from aches and pains, and our Simba mattresses have helped them to reach a great night’s sleep. 

    Recommended Super King Mattress; the Hybrid® Luxe or Ultra super king mattress 

  • How are Simba Super King mattresses delivered and how much does it cost?

    Don’t worry, these luxurious mattresses are delivered free of charge, even in super king mattress sale periods. Some mattresses are rolled and boxed for extra convenience, like our Comfort range and Deluxe mattresses. Our entire Earth range, comes flat, unboxed and ready to go; you’ll get VIP delivery on these to a room of your choice. 

    You have 200 nights to decide whether you are happy with your new super king mattress. But if you decide you’re not, for whatever reason, you can arrange a free collection.  

  • Can I buy a refurbished mattress for a super king bed?

    Yes. We believe refurbishment represents a more responsible use of resources and also gives more people the opportunity to enjoy better sleep at a lower price. 

    So any super king mattresses returned to us are rigorously inspected and assessed by our expert renewal team for refurbishment. Then they’re either recycled or refurbished by our trusted third partners, where they check, deep clean and sanitise every single component, replacing them where necessary, before a final inspection to receive a certified Simba guarantee. 

    For more information check our range of Refurbished Mattresses

  • Is my super king mattress recyclable?

    Because we’re committed to sending no mattresses to landfill, all the super king size mattresses for sale at Simba are suitable for recycling via our collection service or specialist providers. If you return a mattress during your 200-night trial (or under our 10-year guarantee), it’ll be refurbished; any with too much wear and tear are recycled. And when your mattress reaches the end of its life, check out the specialised Simba Mattress Recycling Service on our site: pay a small fee, and we collect it for you. Any brand, any size – no Simba purchase necessary.

  • How to care for and maintain your super king mattress

    Rest easy: you don’t need to flip your Simba super king mattress at any point. What we do suggest is rotating your Comfort and Deluxe mattresses head to foot once a month for the first three months, then once every three months for the rest of its life. As for our super king Earth mattresses, twice a year after the first few months is enough, so your natural mattress fillings stay comfortable for longer. 

    Simba mattresses in our Comfort and Deluxe ranges feature a machine washable cover you can zip off and wash, but it’s also a good idea to get one of our quilted cotton Super King Size Mattress Protectors to help protect your mattress from accidental spillages and general wear and tear. 

  • How long will my Simba super king mattress last for?

    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.

  • Looking for a firm super king mattress?

    There’s no universal industry system that scores one so-called ‘firm mattress’ against another. But we believe a medium-firm super king mattress is most likely to offer the comfort our customers are looking for, so we’ve created our Hybrid® mattresses accordingly. They’re designed to offer supportive body alignment alongside soothing pressure relief.
