Product Information

When compared to the competition, which we would class as the Nectar Hybrid, the Eve Premium Hybrid and the Emma Premium, among others, Simba’s RRPs are slightly cheaper. That said, depending on the mattress sales that are live at any one time, Nectar, Simba and Emma can often undercut. After four weeks of sleeping on the Simba Hybrid we noticed the height of the mattress had reduced a little where our heavier tester slept. However, Simba does advise rotating the mattress once a month for the first three months, so we will keep an eye on this. (For more guidance, read our feature answering how often should you rotate your mattress?) If you are looking for support, the Simba Hybrid mattress has plenty of it. However, when it comes to pressure relief the amount of comfort depends a bit more on your body weight and sleep position. Our heavier weight tester commented that they felt cushioned no matter how they slept on this mattress, with their shoulders, hips and knees feeling comfortable with no pressure. 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.

Our official B Corp™ accreditation is an accolade that is only awarded to select businesses that promote social and environmental change through how we work and operate, something we consistently strive for. For Simba, protecting the planet is as important as restful sleep. We’re proud to be the first UK-born sleep brand to be awarded certified B Corp™ status. After this comes the Aerocoil spring comfort layer, where up to 2,500 conical springs isolate motion and distribute weight evenly across the Simba Hybrid. Below the coil layer is CertiPUR-certified toxin-free Simba-Pure foam to keep you supported no matter where you sleep on the Simba Hybrid. There’s a helping of Edge Lift Technology here too, so you won’t feel as though you’re falling out of bed if you sleep right up to the edge. Before we make a final judgement, we take any trial runs that might be on offer into account – which is often the case within the bed-in-a-box market – before asking the important question, is the product good value for money?

All our hybrid and foam mattresses are made here in the UK*; we’re committed to local production so that we can support local communities and reduce our carbon footprint. *The latest addition to our range, the Simba Go, will also be made here in the UK from early 2023. The middle Aerocoil comfort layer in the Simba Hybrid features up to 2,500 conical springs designed to distribute weight when pressure is applied, and keep motion transfer to a minimum. Simba describes this layer as its “pride and joy”, with the springs being smaller and slimmer than your average bulky bed spring. The micro 25mm coils are made with strong titanium, so they offer plenty of support without the obvious feel of more traditional springs. 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. The result? You can rest assured our range of Refurbished Mattresses will give you the full Simba experience, at a fraction of the price.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.

Buying a mattress isn’t an easy task, so it’s worth doing plenty of reading before making the plunge. If you still have unanswered questions, below are a few of our guides and best buys that should help answer them: While the Simba Hybrid can feel a little firmer for lighter weights, the sensation of resting on top of the mattress rather than in it is still by no means uncomfortable, and the top layer conformed just the right amount to the body, which was extremely cosy. If you are after an extra layer of comfort, support or cushioning, then the Simba Hybrid Pro with double support could be a better fit. For the ultimate Simba experience, look no further than the 31cm-deep Hybrid Luxe with its plushness and other cosy qualities delivered across ten layers. Overall, the contouring with the Simba Hybrid was good for the majority of our testers. Stomach sleeping seemed to be the least comfortable option, as the firmness doesn’t support the pressure points as well in this position. But again, this is subjective and it depends on your weight and sleeping style. We did notice the cover on our review sample was a little loose and baggy on the mattress, which didn’t look so attractive, but when covered with sheets it really didn't matter.Most of our mattresses are available in standard UK and European sizes (please note that mattress depth varies depending on the model you choose):

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. 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.Simba used 70 prototypes and the “body data of 10 million sleepers” to create the original Hybrid mattress. The five-layer design includes titanium coils and a layer of open-cell graphite-infused Simbatex, which is designed to be a more breathable version of memory foam. The first thing to do of course is get your tape measure out; remember your mattress will sit higher in the room once it’s on its bed frame. If you have room, our Super King Mattresses are the widest mattress we make, followed by the European Queen mattresses; they feel super-luxurious and they’re ideal if you have kids (or pets) that like to creep in for cuddles at night. We also strongly recommend one of our machine washable, quilted cotton Mattress Protectors to help keep your double mattress fresh and clean. The small double Simba Hybrid we reviewed measured 120cm x 190cm x 25cm. As such, we expected it to be a little easier to move around than a double or king. The box measures 107cm x 50cm x 50cm, so it wasn’t cumbersome, however at 24kg in weight, if you need to get it up stairs or into a different room, you will probably need an extra pair of hands to help you.
