What Makes Luxo Living King Single Mattresses Different?

At Luxo Living, we’ve spent over 20 years helping Australians get the rest they deserve, and our king single mattresses are no exception. 

Made for local homes and climates, they combine breathable fabrics with durable high-density foam or pocket springs for lasting comfort. Many include CertiPUR-US® certified foams, meaning they’re safe and built to last. Memory foam options, often recommended by Australian physios for spinal support, offer smart support without the sky-high price tag. Because great sleep shouldn’t be a luxury.

FAQs

Do I need special sheets for a king single bed?

Yes, king single beds need sheets made to fit their unique dimensions. Luckily, you don’t need to look far. Luxo Living’s king single bed sheets are made to match, with styles and materials to suit any sleep setup.

How does a king single compare to a single or double mattress?

Compared to a single, a king mattress is both wider and longer. It’s the perfect in-between for solo sleepers who want extra room without upgrading to a full double bed. Narrower than a double , it’s ideal for smaller rooms where space is limited, but comfort is a priority.
