Bed Frame Buying Guide for AU Bedrooms: Sizes, Materials, and What Lasts

A bed frame is the one piece of bedroom furniture you sleep on every single night for the next decade or two. Get the size wrong and the mattress overhangs or the room feels cramped. Get the joinery wrong and the slats start creaking at year three. This guide covers how to size a bed frame for a real Australian bedroom, how the major frame styles actually differ in practice, and how to spot the construction details that separate a twenty-year solid timber frame from a two-year flat-pack one.

The 30 second answer

For most Aussie households, a Queen bed frame (152 x 203 cm) is the default master-bedroom choice and fits comfortably in a 3.0 x 3.4 m room. A King (180 x 203 cm) is the upgrade if you sleep with a partner and a dog, or want generous shoulder room. Pick a solid timber frame with a slat base for the best balance of durability, mattress support, and price. Pick a platform frame if you want the simplest, lowest-maintenance build. Avoid MDF or particle board frames if you want it to last past the warranty.

Australian bed sizes: what each one actually measures

Australia's bed sizing standard is different from the UK and the US. Before you commit to a frame, check the actual measurements against the mattress you have (or plan to buy). Here is the standard sizing.

If you are upgrading from a Double to a Queen, factor in around 15 cm extra width and a full 15 cm extra length. That extra length is usually the part that surprises buyers: a Queen needs a longer wall than a Double, not just a wider one. Confirm both your wall and your existing bedside tables clear before ordering.

Bed frame styles: platform, slat, and sprung base

These three terms describe how the mattress is supported. They look similar from the outside but feel different to lie on and last different lengths of time.

Platform bed frame

A platform frame supports the mattress on a solid panel or close-set wooden slats with no underlying base required. The mattress sits directly on the platform. The result is a lower-profile bed that uses less vertical room space, with no boxspring or base to buy separately. Platform frames work well with modern mattresses (foam, latex, hybrid) and pair beautifully with minimalist or Scandinavian interiors. 

Slat base bed frame

Wooden slats run across the width of the frame, spaced 5 to 10 cm apart, and support the mattress directly. The most common style in AU. Slats allow airflow under the mattress, reduce mattress weight on the floor, and let the mattress flex naturally. Look for solid timber slats rather than plywood strips, since solid slats hold their flex over years of use.

Sprung base or boxspring bed frame

Less common in Australia now. The frame holds a separately-built sprung base (boxspring) on which the mattress sits. Adds height, adds price, and adds another component to wear out. Mostly seen in traditional or hotel-style beds. Skip unless you specifically want that look.

Material: what your bed frame is actually built from

This is where most of the long-term performance is decided. The same bed shape can be built in three completely different ways, and the difference only shows after a couple of years.

Solid timber (oak, ash, walnut)

The longest-lasting option. A solid timber frame uses real planks for the head, foot, and side rails, mortise-and-tenon or dowelled joinery at the corners, and either timber slats or a solid platform for support. With reasonable care, a solid oak bed frame lasts 20 to 30 years and often outlives the house. The frame is also repairable if a joint ever loosens. This is what our entire bed frame collection at Oak Furniture Store is built from.

Upholstered (fabric over a timber sub-frame)

A timber frame wrapped in foam and fabric. Looks soft and quiet, ideal if you read in bed or want a padded headboard. Lifespan depends entirely on the sub-frame underneath. Good upholstered beds have solid timber sub-frames and last well; cheap ones have MDF cores that fail at the corners after a few years.

Metal frame

Lower priced, lighter weight, often noisier. Bolts loosen and start squeaking after a year or two of use, and the connection points wear over time. Metal frames are fine as a short-term solution but rarely the right call for a bedroom you plan to keep set up for a decade.

MDF or particle board (flat-pack)

Cheapest, weakest, and usually only lasts 3 to 5 years before screws strip and joints loosen under normal sleeping movement. The full reasoning for why we avoid these materials is in our guide on particle board versus solid wood furniture. If a flat-pack bed is the budget option, also consider why a second-hand solid timber frame may serve you better. 

What separates a quality bed frame from a cheap one

Most bed frames look similar in a showroom photo. The construction details that decide whether a frame lasts five years or twenty-five years are usually buried where you cannot see them. Here is what to check (or ask about) before you buy.

1. Joinery at the frame corners. Mortise-and-tenon or dowelled is excellent. Bolt-and-bracket is acceptable if the bolts engage into solid timber rather than into MDF inserts. Screws driven straight into chipboard are the warning sign.
2. Slat material and thickness. Solid timber slats 6 to 9 mm thick hold up over decades. Thin plywood strips bow and crack within a few years of nightly use. Count the slat number too: a Queen should have 14 to 16 slats minimum.
3. Centre support beam. Queen and King frames all need a centre support beam running head to foot under the slats, with at least one centre leg. Without it, the slats sag under the middle of the mattress within a year.
4. Headboard attachment. The headboard should bolt into the side rails and into the foot of the bed at two solid contact points, not screwed into the back panel only. A wobbly headboard is the first thing buyers regret.
5. Side rail height. Side rails should be at least 18 cm deep so the mattress sits inside the frame rather than perching on top. Shallow rails make the bed feel taller than it is and let the mattress shift.

Sizing the bed frame for your bedroom

Pick the bed size first, then check that the room accommodates it with comfortable clearance. Leave at least 60 cm of floor on each side of the bed for walking around and for opening any wardrobe doors. If the bedside table has drawers that pull out, leave 75 cm on that side.

One mistake we see in NZ villas and townhouses: choosing a King because the wall is wide enough, then realising the bedside tables no longer fit between the bed and the side walls. Measure the wall, subtract 167 cm for the King frame, divide the remainder, and check whether what is left on each side fits your bedsides comfortably.

Pairing the bed frame with the rest of the bedroom

A bed frame feels right in a room when the bedside tables and the rest of the bedroom storage echo the same timber tone or finish. The usual companion pieces:

• Two bedside tables in the same timber as the bed frame, one on each side. The most important pairing in the room.
• A chest of drawers or tallboy on the wall opposite the bed for folded clothing storage.
• A wardrobe for hanging items if the bedroom does not have built-ins.
• A blanket box at the foot of the bed for spare bedding and seasonal duvets.
• A statement headboard if the bed frame uses a low or removable head panel.

You can browse the full bedroom collection as a single set, or build it up piece by piece with the bed frame as the anchor. The same room-sizing logic that applies to dining furniture (leaving real walking clearance, matching timber tones) carries across; if you have not seen it, our dining table and dining chair sizing guide uses the same approach.

Frequently asked questions

What is the standard bed size in AU?

The Queen (153 x 203 cm) is the most common bed size in Australia for adult couples and master bedrooms. King Single (107 x 203 cm) is the standard for older kids and teens.

What is the difference between a AU King and a US King bed?

Australian bed sizes differ from US sizes. An Australian King (183 x 203 cm) is slightly narrower than a US King, while an Australian Super King is larger again. If you are bringing US mattresses or bedding into Australia, always check the dimensions carefully because sheets may not fit correctly.

How long does a solid wood bed frame last?

A solid oak or solid ash bed frame, built with mortise-and-tenon or dowelled joinery and proper slat support, typically lasts 20 to 30 years of daily use. Many outlast the house they were bought for and are passed down. The first thing to wear is usually the slat base, which can be replaced individually without rebuilding the frame.

Do I need a boxspring under my bed frame?

No, not for a modern slat or platform bed frame. Modern foam, latex, and hybrid mattresses are designed to sit directly on slats or a solid platform. A boxspring adds height and cost without adding much support; skip it unless your specific mattress brand requires one.

What is a platform bed frame?

A platform bed frame supports the mattress on a solid panel or close-set slats with no need for a separate base or boxspring. It sits lower, looks cleaner, and pairs well with modern mattresses. 

Can a King bed frame fit through a standard Australian doorway?

Yes. Bed frames in Australia are usually shipped flat-packed or in separate components (headboard, footboard, and side rails) for exactly this reason. A standard interior doorway clears every Australian bed frame component. The mattress is the part to watch: a King mattress flexes through a standard doorway with a small lift, but thicker pillow-top mattresses may need to come in vertically.

Is a slat base or a platform bed better?

For most Australian buyers, a slat base offers better mattress airflow and a slightly more forgiving feel, while a platform offers a cleaner low-profile look. Both are durable when built from solid timber. Choose based on the look you want and the mattress you have; both will support the mattress equally well over the long term.
