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. 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.

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. 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. 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:

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. 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. Yes. All Simba mattresses are 100% recyclable, so there’s no need for any Simba mattress to go to landfill at the end of its life. In fact for a small fee we offer a removal service for your old mattress whenever you buy a new one from Simba; whatever the brand or size, we’ll make sure it’s properly and responsibly recycled. 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. 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.

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

Does the Simba Hybrid Luxe mattress' 10-layer design deliver a premium sleep experience?

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 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. Above the airy Aerocoil layer, and keeping things cool beneath the soft hypoallergenic cover, is open-cell graphite-infused Simbatex, which offers 30 times more airflow than memory foam, while also adding an extra layer of comfort. The graphite naturally draws away heat from the body to bring even more freshness to the Simba Hybrid.

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. But if you’re concerned about not having enough space, do have a look at our King Size Mattresses; they still feel really indulgent without taking up the entire bedroom. Alternatively, we offer a wide range of cool and comfortable Double Mattresses for you to choose from. 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. 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.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?

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. 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 are founding members of BRC climate action roadmap. All Simba mattresses are made in the UK in zero waste factories from 100% recyclable materials, reducing air miles in the process. Our foam is CertiPUR® verified and free from dyes and heavy metals. Nothing is sent to landfill and all waste is recycled or repurposed into other products – like dog beds and carpet underlay! This is similar to the Nectar Original, which also took up to 72 hours to be fully ready during our Nectar Memory Foam Mattress review. At the other end of the scale, the Emma Original was ready to sleep on within minutes from unboxing. 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.

What size is a Simba double mattress?

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.
