How do our sleep experts help us?

We started working with sleep experts to understand mattress testing better and provide more in-depth information to our readers.

From the very beginning of our deep dive into the testing process, our experts have helped us identify some key aspects to consider when testing.

Some of these include the degree of firmness, sinkage depths, and sleeping positions.

sleep positions

We've used our guiding expert knowledge as a base to structure our testing process.

You'll find a complete guide to our testing process on our product research methodology page.

But our experts haven't only guided our processes - they've also been instrumental in shaping our knowledge base by sharing their experiences with us.

They've guided us in understanding that there is no one-size-fits-all mattress and that different body types and builds have different mattress requirements, continuously highlighting the importance of mattress ergonomics, body posture, and optimal spinal alignment.

Their knowledge of different mattress materials and the best mattress designs, the human body, and optimal alignment has been paramount in helping us decipher how well-suited a particular mattress would be for a specific individual.

But they haven't only helped us with mattresses.

Expert knowledge has been instrumental in shaping our understanding of a wide variety of sleep accessories as well, including pillows, mattress toppers, duvets, bed frames, and more.

They've shared their understanding of how different mattresses and sleep positions require the use of different pillows, and how sleep accessories can affect your overall sleep quality.

Over the last little while, Sleep Hero has also grown beyond being a product review site, and other sleep-related matters interest us.

We're asking ourselves questions about some vital topics, such as:

  • How do you deal with sleep disorders?
  • Does diet affect your sleep?
  • How can your mattress help with back pain?
  • How much sleep do you really need?
  • Which modern sleep gadgets help you sleep better?

We keep up with all the latest trends and research happening in the sleep world, and our sleep experts are only one call away from providing the medical and scientific background we need to give our readers the best advice.
