How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
Is sleeping on your back the healthiest position?
It is often said that sleeping on the back is the ideal position for good body health. Studies show that this sleeping position ensures peaceful sleep with little movement - you'll often wake up in the same position!
When you sleep on your back, your weight is naturally distributed in the right way, your joints are relaxed, and you avoid any pain. It is the ideal position to prevent neck and back pain. In addition, sleeping on your back also reduces gastric reflux.
One disadvantage is that sleeping on the back promotes snoring.
A quick tip: For ideal spinal alignment, place a pillow under your head or neck and another one under your knees. But avoid this position if you're pregnant - it decreases blood flow to the heart and the baby.
Choosing the right degree of firmness
If you sleep on your back, then it is very important that you don’t sink into the mattress too deeply. If you sink in too deeply, then this will result in a hollow back, leading to back pain. But if the mattress is too firm and you don’t sink at all, then you’re also likely to suffer from back pain.
Optimally, the perfect mattress allows for a little bit of sinkage. We would recommend a mattress between 5 and 8 out of 10 on the Sleep Hero firmness scale. This medium degree of firmness guarantees that your spine will remain in an optimal position.
In addition to the firmness of the mattress, you also need to pay attention to your body weight and height. Heavier-weight sleepers, for example, would benefit from a slightly firmer mattress (6-8 on the firmness scale). Lighter-weight sleepers, in contrast, would benefit from a slightly softer mattress (5-6 on the firmness scale).
The ideal mattresses consist of a combination of a firmer foam and a softer, more adaptable foam in the upper layers. Latex or similar materials combined with memory foam or gel foam are ideal for this purpose. This offers you a stable but comfortable upper layer.
