What you’ll get

  • A personalised ComfortScoreTM for every mattress, showing how closely it matches what you need
  • Your top recommendations, ranked by how well they suit you

How does our ComfortScoreTM work?

  1. Start with the basics. Your height, weight and body shape help us work out how much support you need.
  2. Tell us how you sleep. Your sleeping position, any aches or pains, whether you sleep hot, and who you share your bed with.
  3. Pick your size and budget. So we only show you mattresses that work for you.
  4. We then score every mattress in our range. ComfortScoreTM checks your answers against [XX] data points for each of our [XX] mattresses.
  5. See your best matches. Your results are ranked by our ComfortScoreTM within your budget, so you can compare your top picks side by side.

Here’s what your results from our mattress finder quiz could look like:

  • Over 20 years of mattress expertise. We’ve helped over 900,000 customers find the right mattress, and everything we’ve learned has gone into ComfortScoreTM.

  • Built on our full range. Every mattress we sell is scored, so you see your best match, not just our bestsellers.

  • Shaped by real customer feedback. We use customer reviews to check that our scores match real sleepers.

Created by our sleep expert

ComfortScoreTM was created by Hannah Shore, our Head of Sleep Science. Hannah is a University of Oxford graduate with advanced qualifications from the university’s Sleep Medicine Programme and a background in biomechanics.

She analysed our entire mattress range, scoring each one on hundreds of data points, so your mattress selector recommendations are based on how a mattress supports your body.

Meet our Head of Sleep Science

I've spent my career combining the science of how our bodies move and rest with the latest sleep research, because I believe everyone deserves to understand what better sleep really means for them.

With a BSc in Sport Science and an MSc in Biomechanics from the University of Central Lancashire, and a Postgraduate Diploma in Sleep Medicine from the University of Oxford, I bring both academic expertise and practical knowledge to every recommendation you'll find here. All of the advice and product guidance across these pages is informed by my research - including published studies on mattress ergonomics.

My goal is simple: to cut through the noise and help you find a sleep solution that genuinely works for you.

Is it time for a new mattress?

Most mattresses last around 7 years. But if yours isn’t giving you the support you need, it might be ready for an upgrade sooner. Here are a few signs to look out for:

  • You can’t remember when you bought it. If it’s been a while, it’s worth checking how it’s holding up.
  • It’s started to sag or feel lumpy. Dips and lumps mean it’s no longer supporting you evenly.
  • You wake up stiff or achy. Your mattress should help you feel rested, not sore.
  • You sleep better anywhere else. If a hotel or guest bed feels like a treat, your mattress might be the problem.
