What is a King Single Size Mattress?

The king single mattress size falls between a single bed and a double bed. It provides more width than a standard single mattress, offering additional space for a single sleeper. Typically, a king single bed measures around 107 cm wide and 203 cm long, making it longer than a single bed.

The single bed is the smallest bed available in Australian sizes and is a popular choice for children due to its compact nature and manoeuvrability. Despite this, the single bed can be a little too small for growing bodies, resulting in the need to buy more beds or different frames as your children grow up.

This is where the king single mattress outshines against the single bed. Both longer and wider than a single mattress, while still smaller than every other size, the king single bed size is perfect for children while being just as adaptable and compact for guest rooms and most bedrooms.

The king single mattress is perfect for stretching out to accommodate sleeping, with plenty of extra space left over in your rooms for other furniture. Its long single-bed dimensions make it the ideal mattress size to build your room around without sacrificing comfort.

Find Your Perfect Fit

When it comes to the king single mattress size, there are many options available, including differences in materials, durability, and other features. Here's a breakdown of some common options:


  • Innerspring: Innerspring mattresses feature coils or springs at their core, providing support and durability. They may have additional layers of foam or padding for comfort.
  • Memory Foam: Memory foam mattresses contour to the body's shape, providing personalised support and pressure relief. They are known for their comfort and ability to minimise motion transfer.
  • Latex: Latex mattresses offer a responsive and breathable sleep surface. They provide excellent support and durability while also being hypoallergenic and resistant to dust mites and mould.
  • Hybrid: Hybrid mattresses combine different materials, such as innerspring coils and memory foam or latex layers, to offer a balance of support, comfort, and durability.

Durability and Firmness

Durability can vary depending on the materials used and the construction of the mattress. In general, mattresses made with high-quality materials and craftsmanship tend to be more durable and long-lasting. Look for features like reinforced edges and sturdy support systems to ensure the mattress maintains its shape and support over time.

A King single size mattress comes in various firmness options, ranging from soft to hard. The right firmness level depends on personal preference and sleep position. Some mattresses offer customisable firmness levels, allowing sleepers to adjust the feel of the mattress to their liking.

Special Features and Warranty

Some king single mattresses may include additional features such as cooling technology to regulate temperature, moisture-wicking fabrics to promote airflow and keep sleepers dry, or antimicrobial treatments for added hygiene.

Consider the warranty and trial period offered with the mattress. A longer warranty and trial period can provide peace of mind and allow you to test the mattress to ensure it meets your comfort and support needs.

When choosing a king single mattress, it's essential to consider factors such as material, durability, firmness, and any special features to find the best option for your sleep preferences and needs.
