What mattress size fits a standard Australian bedroom?

A Queen (1.53m by 2.03m) fits comfortably in most main bedrooms from about 3.0m by 3.4m, leaving bedside access both sides. A King (1.83m wide) needs roughly 3.3m of clear wall and suits larger main suites. Measure the room and the doorway before you buy.

Is a mattress-in-a-box as good as a showroom mattress?

Yes, for most sleepers. The compression and expansion does not harm the foam, and buying direct usually costs less than the same quality in a showroom. The key advantage when moving in is that it ships to your door and a 30 night trial lets you judge it at home rather than in a two minute store test.

How long does a boxed mattress take to expand?

Most foam mattresses are usable within a few hours and reach full shape within 24 to 72 hours. Unbox it on the base in a ventilated room and the light new-foam smell clears within a day or two.

Do I need a mattress protector straight away?

Yes. Fit a waterproof, breathable protector before the first night. It keeps a new mattress clean and is commonly required to keep the warranty valid. Choose a cotton or bamboo terry style so it breathes in summer.

How do I keep a new bedroom clean after a build?

Vacuum carpet, hard floors and skirtings thoroughly before setting up, because construction dust keeps surfacing for weeks. A robot vacuum scheduled daily handles the ongoing dust under the bed and along edges with no effort, which is useful while you are still unpacking the rest of the house.

This guide has been reviewed for South Australia (Adelaide metro + regional SA). Building licensing, warranty, stamp duty and approval rules differ in other Australian states — verify against your local authority before acting.

The bedroom is the room you will spend a third of your life in, yet it is usually the last one sorted when you move into a new home. Boxes get dumped, a mattress goes on the floor, and six months later you are still sleeping on a setup you chose in a rush on handover week. This checklist walks through the decisions that actually affect how you sleep in a new Australian home: getting the mattress size right for the room, choosing a base, layering bedding for our climate, controlling light and airflow, and getting the space clean before the bed goes in. Costs below are 2025 and 2026 Australian metro pricing for supply and delivery.

Key takeaways

Measure the room first: a Queen usually lives better than a King in a standard Australian bedroom
Get the mattress, protector and pillows right before spending on the frame and decor
A mattress-in-a-box with a 30 night trial is the easiest, lowest-risk option when moving in
Fit blockout blinds and vacuum out construction dust before the first night

Things to consider before you choose

Plain practical advice for Australian builds. No fluff.

Measure the room before you buy the bed

A King mattress is 1.83m wide and needs roughly 3.3m of wall to leave bedside access on both sides. In a standard 3.0m by 3.4m second bedroom a Queen (1.53m wide) usually lives better than a King. Measure the doorway and hallway turns too, because a boxed mattress is easy to move but a built bed base is not.

Mattress first, everything else second

The mattress is the single biggest comfort decision and the hardest to change later. Memory foam suits side sleepers and couples who move at different times because it isolates motion. A mattress-in-a-box ships compressed and expands in a few hours, which makes it the easiest option when you are moving in and cannot get a truck up a new estate street.

Base, ensemble or frame

A slat base with 5cm or smaller gaps supports a foam mattress and lets it breathe. An ensemble base is cheaper and firmer, a timber or upholstered frame looks better but costs more and is harder to move. Whatever you pick, check the mattress warranty, as some require a rigid or slatted base to stay valid.

Protect the mattress from day one

A waterproof, breathable mattress protector goes on before the first night. It keeps spills, sweat and dust out of a brand new mattress and is usually required for the warranty. In Australian summers a cotton or bamboo terry protector breathes far better than a cheap plastic-backed one.

Pillows and bedding for the climate

Match the pillow to how you sleep: a higher, firmer pillow for side sleepers, a flatter one for back and stomach. For bedding, layer a light cotton sheet set with a 250 to 350gsm quilt for most of the year and keep a wool or higher-gsm quilt for cool nights. Natural fibres handle humidity far better than polyester.

Light control and blackout

New estate homes often have large bedroom windows and no established trees, so morning light arrives early. Blockout roller blinds or lined curtains make the biggest difference to sleep quality. Budget around $120 to $350 per window installed, and fit them before you need the room for shift work or a nursery.

Airflow, cooling and power

Check where the ducted vent or split head sits relative to the bed, as sleeping directly under airflow is uncomfortable. A ceiling fan is cheap to run and worth adding if the room does not have one. Confirm there are power points on both sides of the bed for lamps and chargers before the furniture goes in.

Clean the room before the bed goes in

New builds leave fine construction dust in carpet, skirtings and wardrobe tracks that keeps surfacing for weeks. Vacuum the carpet and hard floors thoroughly before you set up the bed. A robot vacuum is handy here because it runs daily under the bed and along skirtings where dust collects, keeping a new room clean with no effort.

Memory foam mattress (in a box)

A visco-elastic foam core with a breathable cover, shipped compressed and expanded at home.

Typical cost: $650 to $1,500 for a Queen

Pros

• Excellent motion isolation for couples
• Pressure relief for side sleepers
• Easy to move into a new home

Cons

• Sleeps slightly warmer than spring unless the cover is breathable
• Needs a few hours to fully expand

Best for: Couples and side sleepers moving into a new home

Pocket spring mattress

Individually wrapped coils under a comfort layer, often with a pillow top.

Typical cost: $800 to $2,200 for a Queen

Pros

• Cooler and more breathable
• Responsive, easier to move on top of

Cons

• More motion transfer than foam
• Heavier and harder to carry upstairs

Best for: Hot sleepers and those who prefer a traditional bounce

Slat bed frame

A timber or metal frame with a slatted base that supports and ventilates the mattress.

Typical cost: $250 to $900

Pros

• Lets a foam mattress breathe
• Storage space underneath

Cons

• Slats can creak over time
• Assembly needed, harder to relocate

Best for: Most bedrooms where looks and airflow both matter

Ensemble base

An upholstered sprung or solid base that the mattress sits directly on.

Typical cost: $200 to $600

Pros

• Firm, even support
• Cheaper than a frame, simple to move

Cons

• Plainer look without a bedhead
• Less underbed storage

Best for: Guest rooms and budget-conscious main bedrooms

How much does it cost in Australia?

Setting up a comfortable main bedroom in a new home from scratch runs roughly $1,500 to $4,000. A good Queen memory foam mattress is $650 to $1,500, a base or frame $200 to $900, a mattress protector $60 to $150, two quality pillows $120 to $300, a bedding set $150 to $400, and blockout blinds or curtains $120 to $350 per window installed. A ceiling fan fitted by an electrician adds around $250 to $450. Buying a mattress, protector and pillows direct from the maker usually beats a retail showroom on price, and a 30 night trial lets you confirm the feel at home rather than after a two minute lie-down in store. Spread the spend if you need to: get the mattress, protector and pillows right first, then add the frame, blinds and furniture over the following weeks.

Common mistakes to avoid

Buying a King because it sounds better, then losing all bedside walking space
Skipping the mattress protector and voiding the warranty on a brand new mattress
Putting a foam mattress on a solid base with no ventilation so it traps moisture
Leaving bedroom windows bare for months because blinds got pushed down the list
Setting up the bed before vacuuming out weeks of fine construction dust
Forgetting to confirm power points on both sides of the bed during the build
