Choosing the right mattress size is essential for creating a comfortable and functional bedroom — especially when space is limited. At Fitting Furniture, we design and manufacture our beds locally in Melbourne, giving you the flexibility to choose from standard Australian mattress sizes as well as compact options that are perfect for kids’ rooms, shared spaces, and clever small-room layouts.

This guide breaks down the most common Australian mattress sizes and highlights how smaller formats like cot, toddler, and Caravan Single mattresses can help you maximise every centimetre of your home.

Standard Australian Mattress Sizes

Single — 92 × 188 cm

A classic choice for kids, teens, and compact bedrooms. Ideal for bunk beds, narrow rooms, and space-efficient layouts.

Long Single — 92 × 203 cm

Same width as a Single but longer. Great for tall sleepers or rooms where you want extra legroom without increasing the bed’s footprint.

King Single — 107 × 203 cm

A little wider and longer than a Single. Perfect for growing kids, teens, and adults who want more space without moving up to a Double.

Double — 138 × 188 cm

A spacious option for solo sleepers or a cosy fit for two. Works well in medium-sized rooms and shared spaces.

Caravan Single Mattress Size (Compact & Space-Saving)

Caravan Single — 70–76 × 188 cm

Although originally designed for caravans, the Caravan Single mattress size is a used in bedrooms where space is tight. It’s narrower than a standard Single but keeps the same length, making it ideal for:

• narrow bedrooms
• lofts and mezzanine spaces
• small guest rooms
• multifunctional rooms
• tiny homes

This size allows you to fit a proper bed into spaces where a standard Single simply won’t work.

Cot & Toddler Mattress Sizes (Perfect for Small Rooms)

Smaller mattress sizes can be a smart, space-saving solution — especially for families with young children or homes with compact bedrooms.

Cot Mattress — approx. 69 × 130 cm

Perfect for nurseries and early childhood rooms. A cot-sized bed frame can fit into corners and tight spaces where a standard bed would overwhelm the room.

Toddler Mattress — approx. 70 × 160 cm

A great transition size between a cot and a Single. Toddler mattresses are ideal for:

• small bedrooms
• shared kids’ rooms
• Montessori-style setups
• low-to-the-ground beds
• rooms where you want to keep floor space open for play

Because we manufacture locally, we can scale many of our designs down to suit cot and toddler mattresses without compromising strength, safety, or style.

Why Smaller Mattress Sizes Are Ideal for Tight Spaces

Compact mattress sizes aren’t just for little kids — they’re a clever way to make the most of limited space. They help you:

• fit a bed into narrow or awkward rooms
• keep more floor space free for play or storage
• create functional layouts in shared bedrooms
• design cosy sleeping nooks
• maintain a clean, uncluttered look in small homes

Smaller mattresses paired with well-designed furniture can completely transform the usability of a space.

Custom Sizes & Made-to-Order Options

One of the biggest advantages of buying from a local manufacturer is flexibility. If your mattress doesn’t match a standard size — or you need a frame built to a specific measurement — we can customise:

• width
• length
• height
• under-bed clearance
• storage options

This includes custom frames for cot, toddler, Caravan Single, and other compact mattress sizes.
