Purchasing a king bed frame is one of the most significant furniture investments you'll make for your home. Unlike smaller beds, a king-size frame becomes the centrepiece of your master bedroom, influencing not just your sleep quality but the entire aesthetic of your personal sanctuary. If you're new to the world of king bed frames, the sheer variety of options can feel overwhelming. This comprehensive guide will walk you through everything you need to know to make a confident, informed decision.

Understanding Australian King Size Dimensions
Before you start shopping, it's crucial to understand that bed sizes vary between countries. The Australian king size measures 183cm wide by 203cm long (approximately 72 inches by 80 inches). This is different from American king dimensions, so if you're looking at imported furniture or reading international reviews, always verify the actual measurements.
When measuring your bedroom for a king bed frame, add at least 60cm clearance on each side of the bed for comfortable movement. You'll also want 90cm at the foot of the bed for walking space. This means your room should be at least 3.5 metres wide and 4 metres long for a king bed to fit comfortably.
The mattress sits on top of the frame, but the frame itself typically adds 5-15cm to both the width and length, depending on the design. Frames with prominent headboards or footboards will require additional space. Always check the external dimensions of the specific frame you're considering, not just the mattress size it accommodates.
Types of Bed Frame Construction
Bed frames come in several fundamental construction types, each with distinct advantages. Understanding these will help you narrow down your options quickly.
Platform Beds
Platform beds feature a solid or slatted surface that supports the mattress directly, eliminating the need for a box spring. These frames typically sit lower to the ground, creating a modern, minimalist aesthetic. They're excellent for foam and hybrid mattresses and often provide superior ventilation through their slat systems. The lower profile makes them ideal for rooms with low ceilings or for those who prefer a contemporary look.
Traditional Frame and Slat Systems
Traditional frames use a combination of side rails, a headboard, and a footboard, with wooden or metal slats spanning the width to support the mattress. The spacing between slats is critical for proper mattress support, ideally no more than 7cm apart for most mattress types. Many traditional frames require a centre support beam for king-size beds to prevent sagging.
Adjustable Bases
Electric adjustable bases allow you to raise the head or foot of the bed independently, offering customised sleeping and lounging positions. While more expensive, they're increasingly popular among Australians who read, watch television, or work from bed, as well as those with certain health conditions like acid reflux or sleep apnoea.
Key Takeaway
Platform beds work best with foam mattresses, traditional frames suit innerspring and hybrid mattresses, and adjustable bases offer versatility but require compatible mattresses designed for bending.
Material Options Explained
The material of your bed frame affects its durability, appearance, maintenance requirements, and price. Here are the most common options available in Australia:
Solid Timber
Hardwood frames made from oak, walnut, or Australian species like blackwood and jarrah offer exceptional durability and natural beauty. Solid timber frames can last generations with proper care and often develop a richer patina over time. They're heavier and typically more expensive, but they provide unmatched stability and a premium feel. Look for frames made from sustainably sourced timber with FSC certification.
Engineered Wood
Medium-density fibreboard (MDF), particleboard, and plywood are commonly used in more affordable bed frames. While less durable than solid timber, quality engineered wood frames can still provide years of reliable service. They're lighter, easier to move, and often feature veneer finishes that mimic the appearance of solid wood at a lower price point.
Metal
Steel and iron bed frames offer industrial aesthetics and excellent durability. Modern metal frames range from minimalist platform designs to ornate traditional styles. They're typically lighter than timber, resistant to pests, and easy to clean. However, metal frames can be noisier if joints loosen over time, and they may feel cold in winter months.
Upholstered
Fabric or leather-covered frames add softness and luxury to the bedroom. Upholstered headboards provide comfortable support for sitting up in bed, and the textile covering helps absorb sound for a quieter sleeping environment. Consider maintenance requirements, as fabric may require regular vacuuming and occasional professional cleaning.
Essential Features to Consider
Beyond basic construction and materials, several features can significantly impact your satisfaction with a bed frame:
- Under-bed storage: Drawers or lift-up bases maximise bedroom space in smaller Australian homes and apartments.
- Headboard design: Consider whether you want a tall statement headboard, a low-profile design, or no headboard at all. Learn more in our headboard selection guide.
- Weight capacity: King frames should support at least 300kg combined weight of sleepers and mattress. Premium frames often rate to 400kg or more.
- Assembly complexity: Some frames require professional assembly, while others are designed for easy DIY setup. Check our assembly guide for tips.
- Noise reduction: Look for frames with rubber or felt padding at joint points to minimise squeaking.
Always verify that your chosen bed frame is compatible with your mattress type. Memory foam and latex mattresses require solid or closely-spaced slat platforms, while innerspring mattresses may benefit from box spring support. Using an incompatible frame can void your mattress warranty.
Setting Your Budget
King bed frames in Australia span a wide price range, from under $300 for basic metal platforms to over $5,000 for premium solid timber or designer pieces. Here's a general breakdown of what to expect at different price points:
- Under $500: Basic metal or engineered wood frames. Functional but may lack premium features or exceptional durability.
- $500-$1,000: Quality mid-range options including upholstered frames, solid pine, and feature-rich metal designs. Best value for most buyers.
- $1,000-$2,000: Premium materials, superior construction, extended warranties, and design-forward aesthetics.
- $2,000+: Luxury and designer frames, Australian-made solid hardwood, and adjustable bases with advanced features.
Remember that a bed frame is a long-term investment. A quality frame that costs more upfront but lasts 15-20 years provides better value than a cheap frame that needs replacing after 5 years. Consider the cost per year of use when evaluating options.
As you continue your search, don't forget to consider practical factors like delivery (will it fit through your doorway?), returns policies (especially when buying online), and warranty coverage. For ongoing care tips, check out our guide on maintaining your bed frame for maximum longevity.
