King Mattresses

king size bed and ensemble

Sleep in the starfish position? Have plenty a spacious bedroom? A King Mattress could be the ideal selection for you!

King Mattresses are perfect for couples who like their own sleeping space, for families and pets who cuddle in bed, for pregnant women, or for those with injuries who need the space to spread out. If it is for your guest bedroom, you can be assured that your guests sleep healthy and wake up feeling amazing, every morning during their stay. Warning, they might not want to go home!

Whether it is for yourself, for you and your partner or even for your guests, you will not be disappointed with the luxury and comfort a King Mattress provides.

King Mattress Dimensions

At 183cm x 203cm, King Mattresses are extremely spacious. They provide restful recovery for pregnant women or those who are injured, as well as ensuring an amazing night’s sleep.

Mattress Size Difference

Our Australian bedding manufacturers advise due to the handmade nature of their mattresses, the length, width and heights listed may vary slightly and they allow a 2 cm tolerance across these measurements.  If you do choose to measure your mattress, please ensure you make these checks from bottom or underside of your mattress.

Chiropractic King Mattresses

Our exclusive Chiropractic Collection — designed by SleepMaker and rigorously tested by the Australian Chiropractors Association — features many King Mattresses. Our Chiro mattresses ensure correct spinal alignment and help you to maintain your posture sleeping, allowing you to achieve a better night’s sleep.
