The ultimate mattress buying guide | Sleepyhead

Our bed buying guide takes the guesswork out of mattress shopping. We’ll help you do a little bit of research before heading in-store to try out your dream bed, find out where to start, the key questions you need to ask yourself and, most importantly, what bed is right for you.

1. Plush, medium or firm mattress, which is best for me?

Whether you like a plush, medium – the best of both worlds, firm or extra-firm bed, choosing the correct feel comes down to your own personal sleeping preference. For example, a plush (soft) feel bed tends to provide pressure relief at core compression points, like the hips and shoulders. This tends to be the perfect choice for side sleepers, whereas front and back sleepers tend to apply an even radius of compression across a wider surface area and might prefer a firmer sleeping environment.


The softest feel in the range offers the highest level of conformance to relieve crucial body pressure points.

Our bed buying tips for choosing the right firmness

2. When you find the mattress firmness you prefer, try a range of beds in that same comfort range.
3. Spend at least 10 minutes resting on the bed you prefer. Kick off your shoes and rest in your natural sleeping position (side, front or back).

2. How do I know what size mattress is best for me?

We all know that sleep plays a vital role in restoring and healing the body. If you’re suffering from sleep problems or feeling tired during the day, it’s important to assess the quality of the mattress you’re sleeping on. Mattress size plays a key role in getting good quality sleep and choosing the right size can depend on a variety of things. For example, how many people will be sleeping with you? What is the size of the person(s) who will be sharing it with you? Do you have kids who like to spend time in bed with you? Do you sleep with your pets on the bed? And so on.

4. Steps to test your bed in store

  1. Dress comfortably and kick off your shoes so you can recreate your normal sleeping environment.
  2. Are there two of you in bed? If so, try the beds together to make sure you’re getting the best solution for both your sleep needs.
  3. Try a range of mattresses within and just outside your price range. Take your time to experience the key differences in a variety of ranges and identify what you liked and didn’t like.
  4. Next, try a range of feels available to see which one you prefer the most – spend at least 10 minutes on each one in your typical sleeping position, ideally with your partner.
  5. Ask one of our expert retail salespeople for some guidance on the various features and benefits available in each bed, i.e. which spring system is used and why, temperature regulation technologies such as Kulkote, allergy support treatments and so on.
  6. You’re ready to make the perfect decision!
