  • Benefits of using a super king size mattress topper

    After a few years of use, even the best king size mattresses will get tired, offering you less support and responsiveness. And this is where a super king size mattress topper helps. Some of the key benefits include:

    ● Extends the lifespan of your super king mattress - helping you save money on replacing the mattress, while reducing your environmental footprint
    ● Provides you with various comfort and support features
    ● Well suited to taller people and couples who find that super king mattresses on their own don’t provide all the support they need
    ● More hygienic - Simba mattress toppers have a removable cover that can be washed

  • Why choose a super king Simba mattress topper?

    A Simba mattress topper means you experience all the innovative features of a super king Simba mattress. Our mattress topper range works with our own mattresses, as well as those of other manufacturers (and even airbeds or pull out beds).

    We designed our mattress toppers for super king mattresses to bring you unique Simba innovations:

    Innovative technology: We’ve packed them with several smart Simba features to help you sleep better, including patented spring designs that provide more support to your body, clever temperature control thanks to our use of open cell foam, and an anti-slip base to give you a secure sleep.
    Better for the planet: We manufacture our mattress toppers in UK factories to reduce their carbon footprint. We also use SimbaPure® foam which is free of CFCs, TCPPs and other chemical nasties, and all materials used are recyclable (and come primarily from sustainable sources). We also offer carbon neutral delivery as well as a collection/recycling service whenever you buy a new mattress or topper from Simba.
    Flexibility: Our mattress toppers work with all kinds of super king size mattresses. They’re also easy to store and carry, and their elastic straps mean they attach securely to the base below.
    Quality guaranteed: Our sprung mattress toppers feature a whopping 365-night trial, free returns and a 10-yr guarantee.

  • What size is a super king size mattress topper?

    Simba mattress toppers in super king size measure: W180cm x L200cm x D7cm

    We also provide single mattress toppers, small double mattress toppers, double mattress toppers and king size mattress toppers

  • Simba Super king size mattress topper materials

    Our research and development teams designed our mattress toppers for super king size beds with sustainably sourced and highly performant materials such as:

    ● CertiPUR® foam
    ● Aerocoil™ springs in polyester pockets

    Simba mattress toppers are made in the UK using 100% recyclable materials - when your mattress topper is at the end of its life, we can collect/recycle it for a small fee whenever you buy a new Simba mattress or topper. Simba packaging is also made with 60% recycled materials, and the rest comes from approved FSC sources.

  • How to wash a super king mattress topper

    Washing a Simba mattress topper is very easy. Start by unzipping the white sleep surface (only the top half), then pop it in the washing machine on a 40°C spin (maximum). You can also tumble dry it on a low setting.
