Product Information

Our mattresses are easy to care for; all you need to do is rotate them once a month for the first three months, and then roughly every quarter after that. You don’t need to turn them over at all. 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. 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.

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. 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. 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. As mentioned, the Simba Hybrid is the original and flagship mattress in the brand's range. It's the second cheapest of the hybrid models – there's also a more budget-friendly Essential mattress, while those looking for an upgrade can opt for the seven-layer Pro or 10-layer Luxe versions (our Simba Hybrid Luxe mattress review will fill you in on that one), both designed to offer enhanced support and pressure relief. 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.

Benefits of using a double mattress topper

We do advise you though to invest in one of our Mattress Protectors; they’re made from soft, quilted cotton and really help protect your mattress from wear and tear. You can even pop them in the washing machine to freshen them up when needs be. For instance, when considering temperature, all-foam mattresses will retain heat more so than others, which would make them a less suitable option for those prone to overheating. 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.

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. 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.

The best double mattresses you can buy in 2023

You can of course opt for one of our standard Single Mattresses or a slightly longer European Single mattress for kids, depending on the size of their bed. But for raised beds or bunk beds we recommend our Hybrid Kids’ mattress; it’s a UK single size but has a shallower depth (16cm) to meet safety regulations.
