King Single Mattress Size
The King Single mattress is perfect for growing children, teenagers, or solo adults who need more room than a standard single mattress. Its extra length provides more legroom, making it ideal for taller sleepers, while its compact width ensures it fits comfortably in smaller rooms without sacrificing comfort. At the same time, its relatively compact width allows it to fit comfortably in smaller bedrooms, apartments, and guest rooms typical of Australian urban housing, where space efficiency is essential.
King Single - 203 x 107 cm
In Australian homes, king singles are often favored for:
- Teenagers transitioning from a standard single who require more space without upgrading to a double bed.
- Solo adults in smaller dwellings wanting a spacious mattress that doesn’t dominate the room.
- Guest bedrooms and multi-purpose rooms that need flexible, space-conscious bedding solutions.
