How to Choose a King Mattress
A king is a big investment, so focus on what matters most to you both:
- Room size: A king works best in bedrooms of about 3.6 × 3.6 m or larger, with space to walk around the bed.
- Firmness: Medium firm suits most couples. If one partner needs more support, look at firm mattresses.
- Motion isolation: Pocket springs and foam layers stop movement travelling across the bed.
- Cooling: A larger bed holds more heat. Cooling gel mattresses and breathable fibres help.
- Base and access: Check your king base or ensemble base suits a 183 cm wide mattress, and measure doors and stairs before delivery.
- Adjustable beds: If you plan to use an electric adjustable bed, choose an adjustable-friendly mattress.

Frequently Asked Questions
A king mattress in Australia measures approximately 183 cm wide by 203 cm long. It's 30 cm wider than a queen and the same length. Sizes can vary slightly between brands, so check the product page before buying a frame or bedding.
A king is worth it if you have the room and want undisturbed sleep. The extra width means less contact and less motion transfer between partners, and it leaves space for children or pets. It's ideal for bedrooms of about 3.6 × 3.6 m or more.
At Bedworld, king mattresses start from $699. Most quality pocket spring, foam and orthopaedic kings sit between $800 and $2,500, and premium luxury models start from around $3,500. Sale prices change often, so check each product for current pricing.
A medium firm pocket spring or hybrid king usually suits couples with different needs. Individually wrapped springs support each person separately and limit motion transfer. Visit our Osborne Park showroom to test options together.
Yes, if the mattress is adjustable friendly. Foam, latex and some pocket spring mattresses bend with the base, while some traditional innerspring designs do not. Our team can recommend king mattresses that suit our electric adjustable beds.
