Bed Sizes And Mattress Dimensions

The importance of bed and mattress sizes in shaping your sleep experience cannot be overstated.

From the dimensions of your sleeping surface to the room you have to move, these factors influence everything from comfort to posture, ultimately determining the quality of your slumber

Picture this: You're nestled under your sheets, ready to embrace the tranquillity of sleep. Your head sinks into the pillow, and your body stretches across the mattress. But wait – is your bed truly the right fit for you?

Australia has seven commonly available mattress sizes.

  1. Single: Ideal for children and teens. 
  2. Single XL: Ideal for one person when space is at a premium.  Also known as Long Single and Single Extra Long.
  3. King Single: Ideal for growing children, teens and mature single sleepers.
  4. Double: Cosy for two sleepers, roomy for one.
  5. Queen: Ideal for couples and the bed size most commonly sold.King: Becoming more and more popular because of its generous sleep area.
  6. King: Tends to be best suited for couples and equivalent to each individual sleeping on their own twin XL bed.
  7. Super King: Not very common as a mattress size, but more popular for bed linen. Created because people often buy a doona and doona cover one size bigger than their bed size.  (For example - Super King linen on a King-size bed).

Below you can find the exact sizes for each bed size. If you are looking for a European bed size, a US bed size or UK bed size, please scroll down.

Maybe you are wondering if you need to buy a new mattress because you wake up with a sore back or neck. More often than not, the neck and back pain people feel comes not from your posture during the day, but how your head rests on your pillow at night. Sleeping on the wrong pillow can make achieving good-quality rest a near impossibility!

A good night’s sleep not only helps recharge your body’s natural energies, but it also goes a long way in determining just how much aching and pain you’ll be feeling the next day. Investing in a high-quality and supportive contour pillow helps ensure you achieve the sort of restful sleep needed in order to enjoy a happier and healthier lifestyle!

Also known as a cervical or orthopedic pillow, this type of support has a curved design that adapts to the head, neck, and shoulders, offering supreme comfort tailored to your body’s build, shape, and size. From our Memory Foam Pillows to our Natural Latex Pillows, our collection of contour pillows give your body the rest you need to perform your best the next day!

If you think your mattress is to blame for your sore neck and back, then you might want to opt for a mattress topper.  Mattress toppers can help you stay cool and get a comfortable night’s sleep. A good night’s sleep is important for you to wake feeling refreshed and ready for the day’s activities. Therapeutic Pillow offers a variety of latex, memory foam and foam mattress toppers designed for the perfect sleep.
