  • 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 180W x 200L (cm). The depth of your super king mattress will vary according to the type of mattress you select; for example the Hybrid® Luxe Super King mattress is our deepest and most luxurious mattress at 31cmD.

  • Why choose a Super King mattress?

    Super king mattress sizes offer a sumptuous sleep space, but here at Simba our super king mattresses are also specially engineered to help you sleep better; our super king mattresses are layered with award-winning sleep tech that offers superb support, increased airflow and limits partner disturbance.

    If you’re worried a super king mattress will be too big for your bedroom, have a look at our UK King Size Mattresses and European Queen Mattresses; both feature all our innovative technology for temperature control and balanced support.

    We also have a range of Double Mattresses, and Small Double Mattresses, as well as a full range of Single Mattresses if you decide to opt for twin beds.

  • Why should I choose a Simba Hybrid® super king mattress?

    Not sure what’s different about a Simba Hybrid® super king mattress? It’s all about the innovative, patented sleep technology we’ve designed, and the perfect balance of support and comfort it creates. Take our cone-shaped Aerocoil® micro springs; they’re engineered to ensure correct spinal alignment and increase air circulation through the mattress, while our airy Simbatex® foam makes sure your whole body stays cooler and more comfortable.

  • 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 and our Green Organic super king mattress offer excellent support for all sleeping styles; the combination of our patented titanium alloy micro springs with pressure relieving foam or organic latex is a winner.

    Recommended Super King Mattress: any Hybrid® super king mattress, or the Green Organic 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 specifically designed to offer tailored support for each partner, limiting motion transfer from one partner to another; their conical design means they compress inwards rather than sideways. They’re strong but also small, so they’re able to nestle unnoticed at the upper surface of your super king mattress where they ensure increased airflow through the mattress.

    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.

  • Which of Simba’s super king 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 bed that natural process is halted, and it’s harder to sleep.

    That’s why all our super king Hybrid® mattresses are designed to keep you cooler; our Aerocoil® springs push air gently through the top layers and the Simbatex® foam in our Hybrid® and Foam mattresses offers more airflow than standard memory foam.

    The Green Organic super king mattress also features these ventilating Aerocoil® springs, as well as breathable organic latex with added perforations to aid air circulation.

    Recommended Super King Mattress: All our hybrid super king mattresses offer superior heat control, but the Green Organic super king mattress is our most eco-friendly option; our Simbatex® foam super king mattresses are also cooler than memory foam and ideal If you ‘re on a budget.

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

    Poor alignment of the spine or inadequate body support can cause debilitating aches and pains, so it’s a good idea to make sure you get extra layers of support and comfort from a deeper mattress such as the Hybrid® Luxe super king mattress.

    For a more sustainable option try our Green Organic Super King mattress, which offers superb cushioning and unrivalled pressure point relief.

    Recommended Super King Mattress; the Hybrid® Luxe super king mattress or the Green Organic 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! They’re also rolled and boxed for extra convenience.  

    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 returned super king mattresses are returned to us and assessed by our expert renewal team for refurbishment; we check, deep clean and sanitise very 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.

  • How to care for and maintain your super king mattress

    There’s no need to wrestle your super king bed mattress onto its other side; just rotate it head to foot once a month for the first three months, and then repeat that process quarterly.

    All Simba mattresses 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.
