King Size Mattresses

Why Choose a King Size Mattress?

A king is the top choice for couples who want the best possible sleep experience. Here's who a king size mattress is well suited to:

• Couples who want maximum personal sleeping space (around 91.5 cm each)
• Taller individuals who need the full 203 cm length
• Families who regularly share the bed with young children or pets
• Those with larger master bedrooms who want the furniture to suit the space
• Anyone after a premium, uncompromising sleep setup at home

Spinal Support in a King Size Mattress

A king size mattress needs to do more than feel comfortable. It needs to support two sleepers of potentially different weights, body types, and sleeping positions, every single night.

Our king mattresses are built to handle this with high-count pocket spring systems where each coil responds independently to local pressure, multi-zone foam layers that provide targeted support for the shoulders, lumbar, and hips, and reinforced edge support that extends the usable sleeping area right to the mattress border. The width of a king also means each sleeper can settle into their natural sleeping position without compromise, which is one of the most underappreciated practical benefits of upgrading to this size.

Mattress Types Available in King Size Mattress

Pocket Spring King

High coil count pocket spring systems respond independently across the full mattress surface, which is especially important for couples on a king where each person's sleeping zone needs to perform on its own.

Memory Foam King

Premium memory foam conforms precisely to body contours, relieving pressure points and providing full-body support across the wider surface of a king.

Gel Foam King

Built for couples who sleep warm. Gel foam actively helps regulate temperature by drawing heat away from the body, which makes a real difference on a shared sleeping surface.

Pillow Top King

A deeply cushioned surface layer over a robust support core, delivering a five-star hotel feel at home. The pinnacle of comfort for those who want to indulge in their sleep setup.

Hybrid King

A strong choice for couples with different sleep preferences. The combination of pocket springs and foam comfort layers gives you the responsiveness of springs alongside the pressure relief of foam.

How to Choose the Right King Size Mattress?

• Room size: We recommend a minimum room size of 4m x 4m to comfortably fit a king with bedside tables and enough space to walk around both sides.
• Combined sleeper weight: Heavier sleepers need more robust support cores. If the combined weight of both sleepers exceeds 200 kg, look for high-density foam bases and high-coil-count spring systems.
• Firmness for couples: When partners have different preferences, a medium-firm is usually a good middle ground. Some brands also offer split-feel options in king size.
• Edge support: On a king, strong edge support means both sleepers can use the full width of the mattress rather than feeling like they might roll off.
• Delivery and access: King mattresses are large and heavy. Before purchasing, measure your staircase, hallways, and doorways to make sure delivery is straightforward. Ask us about our delivery and setup options.

An Australian standard king size mattress measures 183 cm wide by 203 cm long. That's 30 cm wider than a queen (153 x 203 cm), which is a significant difference when it comes to sleeping space.

For couples who want maximum sleeping space and minimal disturbance through the night, a king is well worth it. With around 91.5 cm each, both partners essentially have the equivalent of their own single mattress worth of personal space, while still sharing the same bed.

A standard king measures 183 x 203 cm, while a super king is typically 203 x 203 cm, making it a true square. Super kings require purpose-sized bed frames, linen, and more floor space. Standard kings are much more widely available across a broader range of styles and price points.

Hybrid models that combine pocket springs with foam comfort layers tend to work well for couples with different preferences, as they offer a balanced mix of responsiveness and pressure relief. If the difference in firmness preference is significant, a split-comfort king with different feels on each side is also worth looking into.

No. A king mattress at 183 cm wide is 30 cm wider than a queen frame (153 cm) and won't sit correctly on it. You'll need a purpose-built king size bed frame or ensemble base.

King size mattresses generally weigh between 40 and 70 kg depending on the materials used. Pocket spring models with foam layers tend to be on the heavier end. Having two people available for setup is a good idea, and we offer delivery and installation services if you'd like us to take care of it.
