Who is a Super King best suited to?

Largest bed size

Because it is equally wide as it is long, the Super King bed offers extensive room for a couple to spread out and enjoy restful, undisturbed sleep.

This mattress sits on two separate bases, which helps to reduce partner disturbance. With this in mind, a Super King bed is suited to shift workers and restless sleepers.

It is also ideal for growing families. As the largest bed size available, the Super King has space for young children to join their parents without the bed feeling cramped or crowded.

What size room will fit a Super King?

As the largest mattress available, a Super King is best suited for more spacious bedrooms. In Australia, a master bedroom is often 20 square metres, or 5m wide, which provides enough space to fit a Super King bed.

When measuring your bedroom for an appropriate mattress, it’s important to leave sufficient space around the bed. We recommend a clearance of 75 to 90cm on all sides. This will provide you with ample room to move freely, open doors, and rotate your mattress without bumping into any walls. Do not forget to consider the additional measurements of a bedframe or bed base.
