  • What size is a Simba double mattress?

    Our most popular mattress for double beds is a standard UK double mattress, measuring 135cmW x 190cmL; we also offer a range of longer European Double Mattresses and space-efficient Small Double Mattresses. If you’d like something roomier, have a look at our King-size Mattresses or our Super King Mattresses.

  • Do Simba also offer mattresses in smaller sizes?

    Yes. We also have a range of super-comfortable Single Mattresses as well as the slightly longer Euro Single Mattresses.

  • What to consider when choosing a double mattress

    It’s easy to under or overestimate how much space you have available. So it’s a good idea to measure out the dimensions of your double mattress, making sure there’ll be enough space to open doors and cupboards. But don’t worry about whether you ‘ll be able to get it up the stairs, because all our double mattresses are delivered vacuum packed and boxed.

    A double bed mattress is the perfect size for stretching out, without swallowing up the entire room; it’s a great option for growing teens, smaller bedrooms and guests, but could be a squash for some couples.

  • Choosing the right Simba double mattress

    Woken up by a fidgety partner? Too hot to sleep? All our double mattresses are engineered to keep you cool, comfortable and of course perfectly supported, whatever your sleeping style.

    So what is perfect support? It’s about having the exactly the right balance between a top layer that compresses in response to your body, and an underlying layer that gently resists that response. Without the top comfort layer you’d feel like you were sleeping on a plank, but without the support layer you’d feel like you were sleeping on a trampoline.

    And how do Simba achieve that balance? With our unique blend of Aerocoil® springs and Simbatex® foam (or in the case of the Green Organic mattress certified organic Latex), all of which have the benefits of increasing airflow through the mattress. Simba’s foam mattresses don’t have springs, but extra foam layers provide sufficient support.

  • How to care for your Double Mattress

    There’s no need to turn your double mattress over to prolong its life; just rotate it head to foot once a month for the first three months, then every quarter after that.

    We also strongly recommend one of our machine washable, quilted cotton Mattress Protectors to help keep your double mattress fresh and clean.

  • Will my new double mattress qualify for Free Delivery & Returns?

    Yes. All our double mattresses are delivered free of charge, rolled and boxed for efficient, convenient transportation; just give them 48 hours to regain their shape. Returns are free too; you have 365 days to decide whether you are happy with your purchase, and if not we’ll collect it from you free of charge.

  • Can my double mattress be recycled?

    We don’t want any of our mattresses to end up in landfill. That’s why we make sure all Simba mattresses are 100% recyclable. It’s also why we offer a removal/recycling service for your old mattress (even when it’s not one of ours) when you buy a new one from us.

  • Can I buy a refurbished Simba double bed mattress?

    Yes, we often have double mattresses available in our Simba Refurbished range.

    We refurbish or recycle all the mattresses that are returned to us; it’s kinder to the planet and makes our unique Simba sleep tech more accessible to everyone. Having tested every single component, we replace parts, deep clean and sanitise everything, before a final inspection by our expert renewal team to receive a certified Simba guarantee.

    The result? You can rest assured our range of Refurbished Mattresses will give you the full Simba experience, at a fraction of the price.

  • Need a new double bed frame for your mattress?

    Have a look at our beautifully made, easy-to-build, Upholstered Bed Frames. You can choose from three stylish designs, each of which is available in three different colours and a variety of leg colour and shape.

What are the different types of Simba double bed mattress on offer?

The Green Organic Double Bed Mattress: The natural choice, for climate-conscious couples

Our most sustainable mattress: Rest easy. Because the organic mattress offers all the usual Simba comfort, but it’s crafted by hand from certified organic Latex and recycled or renewable materials.
Superb cushioning: A Latex layer offers superb cushioning and unrivalled pressure point relief.
No partner disturbance: Ideal for couples, our Aerocoil® springs prevents motion transfer from one partner to another
No overheating: If you get too hot to sleep at night, sharing a double bed can make it worse. But Simba’s unique mix of patented springs and cushioning, breathable latex encourages increased airflow to keep you cool.
