King mattress dimensions*

When evaluating standard mattress sizes, the traditional king mattress size represents the pinnacle of personal space for couples. Measuring an approximate size of 1,830mm* (W) x 2,030mm* (L), a king mattress is substantially bigger than a standard double mattress or queen. It offers roughly an incredible 300mm of additional width compared to a queen, giving you and your partner a generous amount of extra wiggle room to rest without compromise. While it requires a larger room to fit comfortably, compared to smaller mattresses, it shares the approximate 2,030mm length as a queen, ensuring it fits beautifully against standard walls while leaving sufficient space for walkways and companion furniture pieces.

*Dimensions are approximate and may vary based on the mattress brand. Please refer to our Bed Sizes Guide for specific brand dimensions.

Frequently asked questions

Who is a king mattress best suited for?

A king mattress is tailored perfectly for couples who desire maximum personal space, light sleepers easily awoken by movement, and families who love a little extra room for weekend morning cuddles. It generally requires a generous bedroom footprint, making it the definitive choice for a principal master bedroom.

What is the difference between a King mattress and a Queen?

The primary difference is the overall width. While both options share an identical length of 2,030mm, a standard king-size mattress is approximately 1,830mm wide, making it approximately 300mm wider than a queen. This extra width provides each adult with the equivalent sleeping space of a standard single mattress, giving you all the extra space you need to move freely.

Will a king mattress fit on standard king bed frames?

Yes, all the king mattresses in our collection are built to standard Australian dimensions, meaning they will fit seamlessly on standard king bed frames. We recommend checking the internal dimensions of your bed frame or choosing a matching set from our bedroom furniture range for an exact fit.

How do I choose the correct firmness for a king bed?

Your choice should be guided by your sleeping position. Dedicated side sleepers usually prefer a medium or plush surface that relieves pressure on the shoulders and hips and cradles your body. Meanwhile, back and stomach sleepers require a firmer or extra-firm support feel to maintain healthy spinal alignment and prevent sagging throughout the night.

Where can I test a king mattress before buying?

You can experience our full range of mattresses in-store at any Bedshed location. Trying the mattresses in person allows you to find your ideal bed and take advantage of great deals with the guidance of our expert sleep team.

Real Reviews by Real People

Tempur Zero G has been great as my husband has mobility issues. He can now get in and out of bed more easily. The remote is simple to use and the delivery men adjusted the legs perfectly. It is also easy to get the vacuum under it.

Heather

The King Single that I purchased is very good for a restful nights sleep with no pain in the morning.

Kevin

We have to give this mattress 5 stars. After being recommended to try this mattress I was surprised as it’s comforting and supportive at the same time. And I think we all wonder what it will be like when we get it home. Well it’s the same. Perfect for us.
