Best matress tips and tricks right now? When Casper first launched as a bed-in-a-box mattress company seven years ago, it did so with the Casper Original. This bed has undergone upgrades since then and, in addition to the all-foam Original, is also available as the Original Hybrid (which places 13th in our ratings). One of the biggest ways the Original Foam has improved from the first Casper mattress is with its AirScape foam. This top layer in the mattress has small holes across the entire surface to increase airflow. It’s designed to combat one of the major drawbacks of a foam mattress: overheating. Underneath this is a foam layer that has a section of firmer foam under your hips and lower back for more support. This zoned support relieved neck and back pain for some professional reviewers.

It comes at a cost, but our reviewer has slept better than ever since having the Simba Hybrid Luxe. With barely any motion transfer and amazing edge-to-edge support, sharing a bed is never a problem. To add to this, the mattress has several layers that aid cooling among its 10 (yes 10) layers. There is an open cell casing wrapping a moisture wicking bamboo wool layer and a bamboo sleep surface that can be removed for washing. Overheating is less of a problem and only on the hottest nights does our reviewer find herself kicking off the covers. Paired with Simba’s Hybrid duvet temperature regulation is much easier. It also has three layers of springs in total. Two rows of 25mm Aerocoil springs sit together, then there are larger 40mm carbon steel springs further down the mattress. What this results in is not only supreme support, but really good weight distribution and minimal motion transfer – a must if your bed fellow is a fidget. Finally, we must mention Simba’s efforts towards making the most sustainable mattress they can. Their foam is made from recycled materials and fast-growing bamboo has been used in place of sheep’s wool to make this mattress pretty hot on eco credentials. The only drawback is the cost as starting at over £750 for a single, this may be out of the price range of many. If you can afford it, it is a great investment in amazing sleep.

We were thoroughly impressed with this hybrid mattress. A layer of memory foam moulds to your body, gently cradling you, while a layer of springs gives more considered support, which saw us wake without any aches or pains. Just under the surface of the mattress is a layer of wool, which has natural temperature-regulating and hypoallergenic properties. We didn’t overheat on the Simba hybrid pro, and there was a noticeably improved amount of airflow compared to traditional, older-style memory foam mattresses. The hybrid pro has edge-to-edge support with no trail off towards the sides. A multi-zoned foam layer at the base adjusts to movements and body shape to ensure you’re held in all the right places. With seven layers, this is Simba’s second thickest mattress, so it’s definitely at the more luxurious end of the spectrum.

Your bodyweight will determine how firmness feels to you. As a general rule of thumb, heavier people prefer firmer mattresses, as soft mattresses may see them sinking, and not getting enough support. On the other hand, lighter builds might find that firm mattresses result in pressure points. Sleeping position also has a role. Back and stomach sleepers prefer firm mattresses – their weight is more distributed, so they will benefit from the support without feeling any pressure. Side sleepers tend to prefer softer mattresses because they have less surface area in contact with it, which increases pressure on hips and shoulders. See even more details on Mattressly.

The soft outer cover provided a lot of give but the springs beneath provided a sleep experience that was both cushioning and supportive for the back and shoulders. The Simba sleep app, which you can download to your smartphone is a nice accompaniment. It’s a tracker that helps you discover your sleep style – our testers were Night Owl and Sleep Master since you ask – and offers tips to improve your night, tailored to the way you slumber. For our restless ‘Night Owl’ sleeper, the Pro felt a little warmer than some other hybrids but our ‘Sleep Master’ was out like a light and stayed that way until morning. You can take up to 200 nights to decide if you like it, there’s a 0% finance option and a 10-year guarantee.
