  • Why choose a King size mattress?

    As with all mattresses it depends how much space, what size bed you have, and who’ll use it!

    A King size mattress is ideal for couples, offering ample sleeping space; just pair yours with one of our UK King Size Beds for a great Simba sleep.

    But if you have kids who like to come into your bed at night then one of our UK Super King Size mattresses is the answer; for the nearest equivalent EU size check out our European Queen mattresses.

    If you need to size down, Double Mattresses are a space-efficient option, while Small Double Mattresses are great for growing teenagers or spare rooms, as are Single Mattresses that can be used in pairs.

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 Natural Hybrid® 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.

  • Natural Hybrid® Mattresses

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