  • 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 varies with the type of mattress you select; for example, our Natural Hybrid® range is packed with natural mattress materials and our signature sleep tech, with our Apex model measuring 30cm deep. But our Hybrid® Essential is just 20cm deep, so please check the product details before buying.

    If you’re concerned a Super King will be too big for your space, we recommend considering a King Size Mattress. Otherwise head over to All Mattresses for more details about our range. 

  • 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.       

    Find out more about our Mattress Recycling Service here.
