  • Benefits of using a king size mattress topper

    After a few years of use, generic mattresses can start to get tired, losing their support and responsiveness. Using a king size mattress topper is a smart solution to this common problem. Benefits include:

    • Extends the lifespan of your mattress - avoiding the costs of buying a new mattress while also reducing your environmental footprint
    • Boost your comfort quickly with the various comfort and support features of a Simba mattress topper
    • Ideal for taller people and couples who find mattresses alone don’t provide all the support they need
    • Easier to clean, Simba mattress toppers have a removable cover that can be washed
  • Why choose a king size mattress topper from Simba?

    Because we use exactly the same, innovative tech you’ll find in our award-winning, top-rated king mattresses in all our mattress toppers, which in our view makes them among the very best mattress toppers you can buy.

    We’ve engineered our mattress toppers in this size to bring you unique Simba innovations:

    • Clever technology: We’ve packed our king mattress toppers with several smart Simba features to help you sleep better. These include our high-tech springs which are designed to provide greater support and enhance freshness thanks to our open structure foam, and an anti-slip base to give you a secure sleep.
    • Homegrown: Simba king size mattress toppers are made in the UK, and we use CertiPur® foam which is certified free of heavy metals. We make sure the materials used in our mattress toppers are as recyclable as possible. We also offer a recycling service when you buy a new mattress or topper from us.
    • Flexibility: A Simba mattress topper works with all kinds of king size mattresses. They’re easy to store and carry, and their elastic straps mean they attach securely to the base below.
    • 200-night trial: Our ingenious, sprung mattress toppers feature a 200-night trial, free returns and a 10-yr guarantee.

  • What size is a king size mattress topper?

    Simba king mattress toppers measure: W150cm x L200cm x D7cm

    We also provide single mattress topperssmall double mattress toppersdouble mattress toppers and super king size mattress toppers.

  • King size mattress topper materials

    Our engineers work hard to source highperformance materials in our king size mattress toppers, including:

    • CertiPur® foam
    • Pocketed Aerocoil™ springs

    Simba mattress toppers are made in the UK using recyclable materials; when your mattress topper is at the end of its life, we can remove and recycle it for you when you buy a new mattress from us (and for a small fee).

  • How to wash a king size 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.
