ad collaborative post | A king-size bed offers the perfect sleeping solution for most couples, providing a generous 15cm more width and 10cm more length than a standard double bed. This extra space ensures a comfortable night’s sleep for 99% of couples, giving you both plenty of room to stretch out and find your perfect sleeping position.

But what if you’re looking for even more luxurious space? That’s where the super king comes into play. Super king beds offer an impressive 30cm more width than king-size beds while maintaining the same length, making them an ideal choice for spacious bedrooms where you want to maintain valuable floor space at the foot of the bed.
The choice between these two bed sizes ultimately comes down to your personal space requirements, both in terms of sleeping area and available room space. Here’s everything you need to know to make an informed decision:
Sizing the beds up
A king-size bed comes with a mattress measuring 150cm x 200cm (width, length), whilst a super king bed boasts more generous proportions with a mattress size of 180cm x 200cm. These measurements are crucial when planning your bedroom layout.
The super king’s additional width represents a significant 20% increase in sleeping space. To put this into perspective, that extra 30cm is equivalent to the width needed for a full-size adult lying on their back – quite a substantial difference when you’re considering your options!

When considering whether more space equals better sleep, it’s worth noting that king-size beds already offer a generous 15cm more width and 10cm more length than double beds. This size comfortably accommodates a large couple or even three people (perfect for those occasions when your little one wants to snuggle up between mum and dad). King size beds strike an excellent balance between spaciousness and practicality, providing ample sleeping room without dominating your bedroom space.
Super king beds, with their impressive width, can comfortably sleep four adults, which means a couple will have an abundance of space regardless of their size. You’ll never feel cramped or confined, and there’s plenty of room for stretching out, reading, or working on your laptop in bed.
However, it’s important to note that super king beds might be too broad for most standard bedrooms. While some double bedrooms can accommodate a king-size bed quite comfortably, fitting a super king often proves challenging unless you have a particularly spacious room. The extra width can make the room feel cramped and restrict movement around other furniture.
Measuring up your bedroom
When it comes to bed placement, you’ll need to allow at least 50cm of clear space around the front and sides of your bed for comfortable movement. While both kings and super kings share the same 200cm length, the super king’s 180cm width requires significantly more lateral space than its king-size counterpart.
Consider these essential factors when measuring your room:
- Adequate space for comfortable movement around the bed
- Clearance needed for doors to open and close freely
- Sufficient room for existing or planned storage furniture like cupboards and wardrobes
- The overall aesthetic balance of your bedroom (will the bed’s size overwhelm the space?)
Even if your measurements suggest a super king could fit, it’s worth considering whether the extra space justifies both the higher price point and the potential impact on bedroom intimacy.
How much do you value intimacy?
The bed size you choose can significantly impact your relationship dynamics. A king-size bed offers an excellent balance, keeping you close enough to maintain intimacy while providing sufficient personal space for comfortable sleep.
Super king beds, with their additional 30cm width, create more physical distance between partners, which some couples find can lead to feeling disconnected during bedtime. This extra space, while luxurious, might not be conducive to maintaining the same level of closeness and intimacy that a king-size bed naturally encourages.
Whether or not this extra space is beneficial largely depends on your personal preferences and sleeping habits. Perhaps your partner’s nocturnal movements and snoring make proximity less than ideal?
In such cases, a super king bed could be the perfect solution for maintaining both relationship harmony and quality sleep (though you might want to broach this subject delicately with your partner!). To enhance your sleeping experience further, consider investing in luxurious silk bed sheets, which can transform either a king or super king bed into an even more sumptuous retreat.
Super kings cost more than king beds – so look for deals!
When it comes to the financial aspect, it’s worth noting that super-king mattresses typically command a higher price point than their king-size counterparts. If you’re working within a specific budget, a king-size mattress and bed frame often represent better value for money whilst still providing generous sleeping space.
The price differential isn’t insignificant – you can expect to pay between 10% and 20% more for super king options. This premium applies not just to the mattress but also to bed frames, bedding, and accessories.
It’s also important to consider that some mattress manufacturers limit their range to king size as their largest option, viewing super king as a specialist size. This limitation can restrict your choices when selecting your perfect mattress, particularly if you have specific requirements for comfort or support.

A mattress-in-a-box makes life easier, whichever size you choose
For both king and super king sizes, mattress-in-a-box options have revolutionised the buying and installation process. These innovative products make navigating tight corners and narrow staircases significantly more manageable than wrestling with a traditional mattress, regardless of which size you choose.
These cleverly designed mattresses arrive vacuum-packed and compressed to approximately one-third of their original size, neatly contained within a manageable box (hence the name). This convenient packaging solution has made upgrading to larger bed sizes more practical than ever before.
Most modern hybrid mattresses and an increasing number of innerspring options now come in this format, making the transition to a larger bed size remarkably straightforward.
