Most of our mattresses are available in standard UK and European sizes (please note that mattress depth varies depending on the model you choose): 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. As we explain in our feature answering what is a hybrid mattress, this type of mattress has multiple layers to boost sleep comfort. Here there are five layers of the Simba Hybrid each offer qualities that combine to provide overall comfort and cooling. The top layer is the breathable surface, followed by a layer of open-cell graphite infused Simbatex foam for temperature control. The hot sleepers on our review panel found it effective. The best memory foam mattresses work hard on cooling, as foam is notorious for trapping heat, so we’re pleased to see Simba focus here. 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. Yes. We also have a range of super-comfortable Single Mattresses as well as the slightly longer Euro Single Mattresses.

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. 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 result? You can rest assured our range of Refurbished Mattresses will give you the full Simba experience, at a fraction of the price. verifyErrors }}{{ message }}{{ /verifyErrors }}{{ We tested the Simba Hybrid in a small double size for four weeks before writing our review. We focused on performance, rating it on pressure relief, motion isolation, temperature regulation, edge support and durability, as well as ease of set-up. The Simba Hybrid is a solid and affordable choice if you are after a reliable and breathable hybrid mattress, made from non-toxic materials and from a trusted brand. If you are lighter in weight it might be a little too firm, and this mattress is probably not ideal for all stomach sleepers either. But overall we really enjoyed sleeping on the Simba Hybrid and found it performed very well. During our review period, our lead reviewer found the Simba Hybrid mattress was comfortable from the first night, especially for side sleeping, although a couple of stomach sleepers on our testing panel found the mattress too firm. The Simba felt breathable, and the motion isolation was also very good – the co-sleepers on our testing panel weren't disturbed by each other getting in and out of bed. While the comfort of the Simba Hybrid was obvious from the first night, we did feel there was an adjustment period with this mattress, but after a couple of weeks we fell into a comfortable place with it. One of our main reviewers noted an improvement in knee pain, which had been an issue when sleeping on their previous innerspring mattress. 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?)

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. 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. The Premium Hybrid is brilliantly comfortable and supportive, and it does a great job of keeping you cool throughout the night. Not only that, but we also found it to be very effective when it came to reducing motion transfer. As such, it’s a great mattress for light sleepers as well as couples who move around a lot during the night. 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. 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.

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.
