A king single with trundle is a space-efficient bed frame that features a full-size king single mattress on top and a hidden pull-out trundle bed underneath. The trundle typically holds either a standard single mattress or a slightly thinner mattress designed to slide smoothly beneath the main bed.
In simple terms, it’s a two-in-one sleeping solution that gives Australian households an extra bed without taking up extra floor space.
The main reason Australians love a king single with trundle is its ability to combine everyday comfort with instant guest accommodation—making it ideal for children’s bedrooms, teenage retreats, holiday homes, and compact living spaces.
Instead of buying two separate beds, a king single with trundle delivers flexibility, practicality, and modern style in one smart furniture piece.
Not all king single with trundle beds are designed the same. Here are the most popular styles available across Australia.
Crafted from solid timber or engineered wood, these frames offer durability and timeless appeal. They suit coastal, Hamptons, and Scandinavian-inspired interiors.
Featuring fabric or faux leather finishes, upholstered options bring softness and luxury. They work well in modern and contemporary bedrooms.
Some models combine a trundle with built-in drawers, providing extra space for bedding, toys, or seasonal clothing.
These trundles lift to match the height of the main bed, creating a temporary king-size sleeping surface—perfect for sleepovers.
Designed for modern apartments, these low-profile frames focus on clean lines and functionality.
Supportive collections from brands like Florabelle Collection, Café Lighting & Living, Gallery Home, OneWorld Collection, Zaffero, and Emac & Lawton often reflect these design trends in contemporary bedroom furniture.
Choosing the right king single with trundle requires more than just picking a style. Here’s how to make the best decision.
Allow space for the trundle to fully extend. You’ll need at least 90–100cm clearance at the foot or side of the bed.
Most trundles require thinner mattresses (15–18cm). Always confirm depth limits.
If adults will use the trundle, choose reinforced frames with strong slat systems.
If your home lacks storage, consider dual trundle-and-drawer designs.
Choose timber for classic spaces, upholstery for luxury, and metal frames for industrial looks.
Here’s why this matters: the right king single with trundle should support both everyday living and occasional hosting without compromise.
