Mattress queen size refers to the standard Australian Queen mattress, which measures approximately 152.5 cm wide × 203 cm long. It is one of Australia's most popular mattress sizes and is designed to comfortably accommodate two adults while fitting into many standard bedrooms and guest rooms.
A Queen mattress offers a practical balance between sleeping space, room proportions and versatility, making it a popular choice for couples, single adults who enjoy extra room and guest bedrooms.
The standard Australian mattress queen size is approximately:
152.5 cm wide × 203 cm long
Some retailers round this to 153 × 203 cm, so both measurements can appear when researching Australian Queen mattresses. Small manufacturing variations are also possible.
| Mattress Size | Approx. Width | Approx. Length |
|---|---|---|
| Single | 91.5 cm | 190 cm |
| King Single | 105.5 cm | 203 cm |
| Double | 138.5 cm | 190 cm |
| Queen | 152.5 cm | 203 cm |
| King | 183.5 cm | 203 cm |
| Super King | 203 cm | 203 cm |
The Queen mattress is popular because it provides a generous sleeping surface without requiring as much bedroom space as a King.
It can work particularly well for:
Its 203 cm length is also useful for taller sleepers compared with a standard Double, which is approximately 190 cm long.
Yes. An Australian Queen mattress is designed to accommodate two adults and is considered a versatile option for couples.
It provides approximately 76.25 cm of width per person if the sleeping surface is divided evenly.
For couples who want substantially more personal space, an Australian King provides approximately 31 cm of additional overall width.
The difference between Double and Queen is significant.
Double: approximately 138.5 × 190 cm
Queen: approximately 152.5 × 203 cm
A Queen mattress is approximately:
This additional space can make a noticeable difference for couples and taller sleepers.
The Queen and King share approximately the same 203 cm length.
The main difference is width:
Queen: 152.5 × 203 cm
King: 183.5 × 203 cm
A King therefore provides approximately 31 cm more width than a Queen.
A Queen can be preferable when bedroom space is limited, while a King is appealing when additional sleeping room is a priority.
Memory foam responds to body pressure and can provide a cushioned, contouring feel.
It may suit sleepers who enjoy:
Pocket springs are individually enclosed within fabric pockets.
They can provide responsive support while helping limit movement transferring across the sleeping surface.
A hybrid combines different materials, commonly springs with foam or latex comfort layers.
Hybrid designs can offer a balance of support, responsiveness and cushioning.
Latex provides a responsive feel and can be suitable for people who prefer a mattress with less sinking.
A firm Queen mattress provides a more supportive, stable sleeping surface.
Medium firmness offers a balance between cushioning and support and is a popular starting point for many sleepers.
A plush mattress provides a softer, more cushioned feel.
Your sleeping position should influence the firmness you choose.
Side sleepers often benefit from cushioning around the shoulders and hips.
Back sleepers generally need balanced support through the body.
Stomach sleepers often prefer a firmer surface that limits excessive sinking.
If two people share the mattress, consider:
A mattress that suits one person may feel very different to another.
Look beyond the exterior fabric.
Check the construction and materials, including:
A Queen mattress itself measures approximately 152.5 × 203 cm, but the bedroom needs additional room for the bed frame, bedside furniture and comfortable circulation.
Sealy suggests a Queen is generally suited to a room around 10 × 10 feet or larger, while other Australian bedroom guides suggest approximately 3.0 × 4.0 metres as a practical starting point.
These are guidelines rather than strict requirements.
Before purchasing, consider:
To confirm your mattress queen size, measure:
Measure from one long edge directly across to the opposite edge.
Measure from the head to the foot of the mattress.
Measure vertically from the bottom edge to the highest point of the sleeping surface.
Record the dimensions as:
Width × Length × Depth
For example:
152.5 × 203 × 30 cm
The exact mattress depth will depend on the particular model.
Yes.
Two Queen mattresses can have identical width and length but very different depths.
Mattress depth can affect:
Always check the maximum mattress depth supported by fitted sheets and mattress protectors.
A Queen mattress requires appropriately sized Australian Queen bedding.
Common Queen bedding includes:
A fitted sheet must accommodate both the mattress's width and length as well as its depth.
For example, a mattress protector designed for an Australian Queen is commonly listed around 152 × 203 cm, depending on the manufacturer.
A Queen mattress should be paired with a compatible Queen bed frame or base.
Options include:
Remember that the external dimensions of a bed frame can be larger than the mattress itself.
Always check the frame's internal mattress dimensions before purchasing.
A Queen mattress is a practical choice for many couples.
It offers enough room for two adults while remaining relatively space-efficient.
For couples, consider:
If both sleepers want significantly more personal space, moving to a King may be worthwhile.
A Queen mattress is particularly versatile for guest accommodation.
It can comfortably accommodate couples while also providing a spacious sleeping surface for a single guest.
A Queen bed can also make a guest bedroom feel more luxurious without requiring the floor area of a King.
A Queen can work beautifully in a medium-sized bedroom when the layout is carefully planned.
Consider pairing it with:
Avoid filling the room with oversized pieces that compete with the bed.
In a master bedroom, a Queen mattress can be styled as a refined focal point.
Consider adding:
The goal is to create balance around the mattress rather than simply adding more furniture.
The proportions of a Queen mattress work particularly well with a range of Australian interior styles.
Combine white or natural linen with pale timber, soft blue and relaxed textures.
Use neutral bedding, clean-lined furniture and sculptural lighting.
Consider upholstered furniture, layered whites, soft blue tones and classic bedside pieces.
Pair natural linen, timber, ceramics and earthy colours.
Use layered textiles, elegant lighting, substantial bedside tables and a sophisticated upholstered bedhead.
A split Queen consists of two separate mattress sections placed together to form the overall Queen sleeping area.
This can be useful for couples who want:
The overall Queen footprint remains approximately the same, but the construction is divided into two sections. Sealy also offers split Queen configurations.
The Australian Queen mattress is approximately 203 cm long, making it considerably longer than a standard Double at approximately 190 cm.
This additional 13 cm can be valuable for taller sleepers.
If you are particularly tall, also consider:
The lifespan of a Queen mattress varies according to:
Signs that a mattress may need replacing include:
Follow the manufacturer's care and warranty recommendations.
To maintain your mattress:
A mattress protector can help protect the sleeping surface from spills, stains and everyday wear.
