What is the best kind of mattress to buy?


We construct our Sealy mattresses using coil springs, which are arranged in a structured way to form the mattress core. A combination of specially selected comfort layers and premium natural materials are applied above the spring unit to assist in conformance and pressure relief.

Sealy innerspring mattresses have many benefits, including:

  • A support system that has been designed with orthopaedic and sleep scientists to cradle your body, relieve muscle tension, and align the body to its natural position
  • Allows for air circulation for a healthier, more comfortable sleep experience
  • A durable structure that provides years of performance for ongoing use

Consider comfort levels when buying a mattress

Comfort levels range from very soft to extra firm. Visit our physical store to try out our mattresses and find your comfort preference or view our mattress buying tips below.

  • Ultra-Plush – exquisitely soft
  • Plush – firmer than the ultra-plush, but not as firm as the medium
  • Cushion Firm / Medium – firmer than a plush but softer than a firm
  • Firm – a firm sleeping surface
  • Extra Firm – the most stable and sturdy of all available comfort levels

Which mattress is right for me?​

front rev


Look for a firmer comfort layer with a quality support system that will keep your spine aligned throughout the night. Softer mattresses may cause lower neck and back pain by allowing your body to curve too much.

side rev


You’ll sleep well on a softer mattress, allowing your shoulders and hips to push deeper into the plushness than the rest of your body. This helps disperse pressure and improves circulation, reducing the chance of tossing and turning at night.

back rev


A medium amount of comfort – not too hard or soft – is right for you. It will ensure that your shoulders, back, and hips are cradled with the right amount of cushioning while the rest of your body can enjoy absolute comfort.

Other things to consider when buying a new mattress

Couple icon


When contemplating what to look for when shopping for a mattress, it’s crucial to consider your partner if you’re sharing a bed. Comfort and support are the keys to avoiding tossing and turning during the night. In many cases, the need to roll over regularly comes from feeling sore or uncomfortable, which often triggers your partner’s movements. The right level of comfort and support is essential to prevent tossing around throughout the night. Mattress size is also important, as some people need more space around them, which can affect the overall quality of your sleep.

Child icon


If you are purchasing a mattress for a child, consider the right size for their needs. Invest in a bigger size, ensuring they don’t outgrow it too soon. A good night’s sleep is crucial for young children, as it can impact their mental and physical development. If you are buying for a guest room, consider a mattress that will cover a wide variety of different sleepers – we recommend a medium to firm mattress in this case.



If you like to sleep in warmer circumstances, you should choose a softer mattress due to the added material and surrounding comfort layers. On the contrary, firmer mattresses are better at helping you stay cool with increased airflow from the elevated mattress surface. Other factors to consider are your choice of bedding, the mattress protector, and the room temperature or airflow in the room.

Allergies icon


Choose a mattress designed to reduce allergies. Look for options that contain natural materials in the upper layers of the mattress, such as wool, silk and/or other natural fibres. A mattress protector can also help to protect against bed bugs, dirt, and allergens.

Health icon


A good balance of comfort and support is vital when selecting a mattress, as it helps to keep the spine aligned and may assist with back ailments or injuries. If you are experiencing sleep issues due to health reasons, speak to your medical practitioner about your best options.

What to do once your mattress arrives

  • When you receive a new mattress, it may have a new mattress smell, so remove the packaging and give it time to air out before putting on your mattress protector and sheets.
  • Some people find that their new mattress feels different from when they tried it in-store. Often, it may feel slightly firmer as it has never been used before. Keep in mind that store mattresses have been tried several times, so they’ll feel softer than brand-new ones. If this happens, give it a try – it should soon be how you remembered it!
  • A mattress will have various layers of padding and foam for adequate comfort.
  • As you lay on the mattress, a body signature will start to form in the place where you sleep. To prevent these impressions from appearing too quickly, we recommend rotating the mattress every 3 – 4 months or with a change of season.

Which mattress is right for me?

  • Buy the best quality you can afford. Good quality mattresses aren’t cheap, but this doesn’t mean you have to spend a fortune to get the right one. What’s most important is finding a mattress that supports you and makes you feel comfortable. Refer to our mattress buying guide for help choosing the perfect firmness.
  • Dress comfortably and take your pillow to the store to simulate your regular sleeping environment.
  • Try out each mattress and take the time to feel the difference, noting what you liked and what you didn’t.
  • Lie on a few different beds within your comfort level. Our retail salespersons are there for guidance to explain each range’s features and benefits.
  • Try before you buy – taking the time to lie on the bed is a valuable investment. Make sure you lie on each mattress for at least 10 minutes in your normal sleeping position to help determine the best fit.
