Product Information

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: 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. 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. 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.

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

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. Most of our mattresses are available in standard UK and European sizes (please note that mattress depth varies depending on the model you choose): 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. 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.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.
