Introducing our sleep experts

He's also owned his own mattress shop for decades and has hands-on experience recommending the best sleep products for a wide variety of people.

โ€‹Walter swears that healthy sleep is the most important thing for our physical and mental well-being, with every part of our sleep setup - from mattress to frame, pillow, and blanket - playing a vital role.

Working with doctors, he knows that many aches and pains are actually related to misaligned sleep. The trick is to find the perfect combination of mattress and frame (and everything in-between) to ensure the ideal sleeping conditions.

How do our sleep experts help us test?

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

From the beginning, our sleep experts have helped us identify the most important aspects to consider when testing products.

These aspects include the sinking depth, firmness level, and sleeping positions.

Perfect for all sleeping positions.

We've used the knowledge of our experts as a basis to structure our entire testing process.

For a complete guide to our testing process, visit our Product Research Methodology page.

However, our experts not only advised us on our testing process but also played an essential role in shaping our knowledge base by sharing their experiences with us.

They've repeatedly reminded us that there's no one-size-fits-all mattress and that different body sizes and types have different requirements, continuously highlighting the importance of posture, mattress ergonomics, and optimal spinal alignment.

Their knowledge and experience of different mattress materials and the best mattress constructions, optimal alignment, and the human body were essential to us in figuring out how comfortable a particular mattress is for a specific person.

But they didn't just help us with the mattress test.

Their expertise has helped our content writing team in shaping the understanding of a variety of sleep accessories such as duvets, mattress protectors, pillows, duvets, and more.

They've shared their knowledge and understanding of how different mattresses and sleeping positions require using different pillows and how other sleep accessories can positively impact the quality of your sleep.

Over the past few years, Sleep Hero has grown beyond just being a product review site, and we're also interested in other sleep-related topics.

We ask ourselves and our experts' questions on some important topics, such as.

  • How does diet affect your sleep quality?
  • How do you deal with sleep disorders?
  • What modern sleep gadgets can help you sleep better?
  • How can mattresses help with back pain?
  • How much sleep do you actually need?

We try to keep up with the latest research and trends in the world of sleep, and our sleep experts have always been just a phone call away to provide us with the proper medical and scientific background knowledge we need to give our readers the most helpful advice.
