A king single mattress measures 106 x 203 cm: wider than a single and 15 cm longer. It's the size kids grow into, with enough length for teenagers and adults while still fitting a smaller bedroom.

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.

Check your bed size

King single and single mattresses (92 x 188 cm) aren't interchangeable, so measure the inside of the bed frame before you buy. Need a frame? See our king single bed frames.

Delivery

Orders are dispatched from our Melbourne warehouse the next working day after payment. The delivery cost to your state is shown on every product page before you check out, and you can pay in four with Afterpay.

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. Outside peak season, delivery usually takes about 3–8 working days in Victoria, 5–10 working days in NSW, SA, ACT and QLD, and 7–14 working days in WA, NT and TAS.
