Why A King Mattress Matters

A king mattress size offers unmatched comfort and elegance for couples and individuals who appreciate plenty of room to move. After all, the quality of this royal-worthy mattress is in the name. With more width than a queen, a king-size bed mattress creates a sense of space and serenity during your night’s sleep. Many of our options also promote better spinal alignment, allowing you to sleep soundly through the night knowing you’re choosing the best option for your back.

Compared to a single, king single, double, or queen mattress the size of a king mattress offers enough space for two adults and even a smaller body like a pet or child to share comfortably. Its width compared to a queen provides that much-needed extra space that transforms an ordinary bedroom into a luxurious sanctuary.

Features to Look for in a King Bed Mattress

When choosing the best mattress for your needs, it’s worth paying attention to what makes a new mattress truly exceptional:

• Support System: Look for precision-engineered coils or pocket springs that minimise partner disturbance while enhancing long-term resilience.

• Comfort Layers: Decide whether a medium firm or soft feel best complements your sleep preferences and sleeping style.

• Durability: Premium materials ensure your investment lasts, preventing sagging and maintaining comfort over time, meaning a good night’s sleep every time.

• Temperature Control: Innovative fabrics and airflow channels promote good sleep all year round.

• Maintenance: Regular rotation keeps your mattress fresh, especially when replacing an old mattress.

• Compatibility: Match your king mattress with our sturdy bed bases or frames for optimal support and longevity.

Frequently Asked Questions

Why should I choose a king mattress?

A king mattress is perfect for anyone who wants room to stretch out and unwind. Its expansive length and width create a sense of luxury that makes it the perfect mattress for couples or anyone seeking ultimate comfort.

How big is a king mattress?

A standard king mattress measures approximately 183cm x 203cm, the same length as a queen but noticeably wider. For even greater coverage, consider a super king mattress option for maximum relaxation.

What’s the key difference between a king and super king?

The key difference lies in width: while a standard king offers ample space, a super king provides even more area for extra comfort and shared support. This makes a super king mattress ideal for those who want the ultimate luxury and plenty of room to stretch out. A super king mattress measures 203cm x 203cm.

Will a king mattress fit in my room?

Most master bedrooms will easily accommodate a king. We recommend you measure your space and the chosen bed to ensure the two are compatible. Also ensure you have adequate room for side tables and movement around the bed. Small spaces that don’t offer much room may only be able to accommodate a queen, double or single mattress.
