A king mattress measures 183 x 203 cm, 30 cm wider than a queen. It's the choice for couples who want more personal space, families with kids who climb in, or anyone sharing the bed with pets.

Mattress types

  • Pocket spring: individually wrapped coils that reduce partner disturbance.
  • Memory foam: contours to your body; cool gel versions sleep cooler.
  • Latex: springy, responsive and breathable.
  • Euro top: an extra comfort layer for a plusher surface.

Which firmness?

Side sleepers usually prefer soft to medium, so shoulders and hips can sink in a little. Back sleepers tend to suit medium to medium-firm, and front sleepers often find firm keeps the spine level. Use the Firmness filter to narrow the range.

Will it fit?

A king bed works best in a room around 3.5 x 3.5 m or larger, with space to walk around both sides. If space is tight, a queen mattress may suit better.

Frequently asked questions

Side sleepers usually prefer a medium to medium-soft mattress that cushions the shoulders and hips, back sleepers a medium-firm one, and stomach sleepers a firmer one that keeps the spine straight. If you share the bed, a medium-firm pocket spring mattress is a good middle ground.

Pocket spring mattresses use individually wrapped coils that support each part of your body separately. They feel bouncier and let air flow through, so they tend to sleep cooler.

Memory foam mattresses mould to your shape and absorb movement, so you feel less of a partner turning over. Cool-gel foam helps reduce heat. Hybrid mattresses combine pocket springs with foam layers.

Orders ship from our Australian warehouse the next working day after payment clears.
