With a super king bed, the extra space helps maintain a serene and luxurious atmosphere, preventing the room from feeling overcrowded. This allows you to create a relaxing environment with ample storage and seating options.
WHO IS A SUPER KING MATTRESS BEST SUITED FOR?
A super king mattress is ideal for those who want the maximum available space or for couples who prefer to sleep without disturbances.
This mattress size offers plenty of room to stretch out comfortably without invading a partner's space, making it perfect for individuals who value personal space during sleep. It is also a great option for families with young children or pets that may occasionally join you in bed, ensuring that everyone has enough room to relax.
Special & Uncommon Bed Sizes
Special and uncommon bed sizes offer flexible options for unique space requirements. The three-quarter bed (107 cm x 190 cm), once popular in smaller rooms, sits between a single and double mattress. A small double (120 cm x 190 cm) offers a bit more space than a king single without taking up the full width of a standard double.
For those with specific needs, custom sizes are also available from select Australian retailers, catering to unique room layouts or spaces such as RVs, boats, or tiny homes.
What’s the Biggest Bed Size?
The biggest bed size commonly available in Australia is the super king, measuring 203 cm by 203 cm.
How To Choose the Right Bed Size
When choosing the right bed size, consider your room dimensions to ensure there's enough space for movement without the area feeling empty.
Your height matters too; taller individuals should opt for longer beds like a king or super king to avoid discomfort. If sharing the bed, factor in both partners' preferences for personal space.
Finally, your sleeping habits are key. If you like to stretch out, a queen or king may be best to ensure there's enough room for both partners to sleep comfortably without any disturbance.
- Here are a few key aspects to consider when choosing the right bed size:
- Room Size: Make sure your bed fits comfortably in the room, leaving enough space for walking, furniture, and easy movement.
- Height: Choose a bed that accommodates your height, especially if you are taller than average.
- Sleeping Arrangements: Decide whether you will be sleeping alone or with a partner, and consider whether you both need extra space.
- Style Preferences: The size of your bed can significantly impact the overall style and feel of your room. Larger beds often make a bold statement, while smaller beds can create a cosier atmosphere.
- Future Needs: Consider any potential changes in your living situation. For instance, a larger bed might be more appropriate if you plan on sharing the space with a partner in the future.
