Why “Bigger King” Is the Buzzword in Modern Bedrooms
If you’ve ever found yourself clinging to the edge of your bed while your partner snores peacefully with limbs spread out, you’re not alone. For couples, bed real estate is a nightly battle. This discomfort is sparking a growing trend: investing in a “bigger king mattress.” But this isn’t just about extravagance. It’s about comfort, better sleep, and what many are calling “sleep independence.”
In a time when people are rethinking their sleep environments, this trend goes beyond size. It touches on personal wellness, relationship dynamics, and even lifestyle. So what exactly is a bigger king mattress, and why is it earning such a loyal following?
What Is a Bigger King Mattress, Really?
The term “bigger king mattress” often refers to mattress sizes that go beyond the standard king, and often considered as Super king size mattress, Depending on where you live, this can mean different things:
In everyday slang, “bigger king” can mean any of these or even a custom-sized bed. What unites them is one thing: extra space.

With Luxe Mattresses, customers can even customise dimensions to suit their specific room or body needs, length, width, firmness, and more. It’s this level of personalisation that is turning a bigger king mattress from a niche product into a mainstream must-have.
The Rise of the Bigger King: Where and Why It’s Trending
While the U.S. has long embraced oversized furniture and bedding, the UK is catching on fast. Driven by trends like co-sleeping with children or pets, hybrid home living (where beds become offices), and simply a desire for better rest, the bigger king is being welcomed with open arms.
Luxe Mattresses, a UK-based custom mattress manufacturer, has noted a surge in orders for larger sizes. The demand isn’t limited to luxury homes either. Even flat owners and small-space dwellers are rearranging rooms to accommodate bigger beds. Why? Because a better night’s sleep is worth the space.
What Room Size Do You Need for a Bigger King Mattress?
When planning to upgrade to a bigger king mattress, one of the most important considerations is whether your bedroom can comfortably accommodate it. While mattresses like the Super King or Alaskan King offer unmatched space, they do require proper planning.
As a general guide:
Super King (180 x 200 cm): Minimum room size should be around 3.5m x 3.5m to allow for walking space and furniture.
California King (183 x 213 cm): Ideal in rooms larger than 3.6m x 3.6m.
Alaskan King (274 x 274 cm): Works best in master suites or large open-plan rooms with at least 4.5m x 4.5mavailable.
Make sure to leave about 60–90 cm clearance on each side of the bed for ease of movement and access to nightstands. If your room is tight, consider wall-mounted or floating furniture to save space. Luxe Mattresses also provides guidance on custom-fitting larger beds into smaller UK rooms with smart layout strategies.
The Science of Space: How More Surface Area Supports Better Sleep
According to the Sleep Foundation, the average person changes position 12-20 times a night. When sharing a smaller bed, these movements often lead to accidental elbow jabs, blanket wars, and fragmented sleep.
Here’s what a bigger surface area can do:
Reduce disturbances from partner movement
Allow freedom of position, from starfish to side-sleeper
Minimise pressure points, especially for people with chronic pain
Support spinal alignment across a wider range of sleeping postures
Add to this the psychological benefit of personal space, and the bigger king starts looking like a necessity rather than a splurge.
Motion Isolation: The Secret Weapon of a Bigger Mattress
Let’s face it, we’re all a bit sleep-fragile during the night. Especially pregnant women, light sleepers, or anyone suffering from anxiety or insomnia.
motion isolation in mattress
Motion isolation refers to how well a mattress absorbs movement so that it doesn’t ripple across the surface. A bigger mattress paired with quality materials (like those found in Luxe’s hybrid or memory foam models) drastically reduces motion transfer.
Your partner can toss and turn without waking you up.
Kids or pets jumping in won’t shock your sleep cycle.
You stay deeper in REM sleep, improving cognitive and physical recovery.
This feature is particularly useful if you’re a light sleeper or dealing with chronic fatigue or hormonal imbalances.
Luxury vs Necessity: Is the Bigger King Just a Fancy Upgrade?
Some may call a bigger king mattress a “nice to have.” But let’s compare it to investing in good shoes or ergonomic office chairs. You spend a third of your life in bed, comfort and support should be non-negotiable.
Couples in particular benefit from space. As relationship therapists point out, personal sleep comfort can actually improvea couple’s intimacy and communication. If one partner is uncomfortable, neither of you sleeps well. That has a knock-on effect on your mood, productivity, and even immune function.
Fitting a Bigger King Mattress in the UK: Yes, It’s Possible
The common concern in the UK is space. British homes and bedrooms are typically smaller than their American counterparts. But thanks to customisation options from companies like Luxe, even modest rooms can be upgraded smartly.
Here’s how:
Use under-bed storage drawers to replace bulky wardrobes
Opt for low-profile headboards or floating nightstands
Choose a split or modular mattress for easier delivery and flexibility
Customise the length and width to fit your unique layout
Real-Life Story: “We Finally Stopped Fighting Over Space”
Amy and James, a couple from Leeds, upgraded from a double to a custom super king Luxe mattress last year.
“We were sceptical at first, our bedroom isn’t huge. But we called Luxe, explained our needs, and they helped us customise the dimensions to fit our space. The difference was immediate. No more kicking each other at night, no more sleep arguments.”
Their Luxe mattress even came with dual firmness soft on Amy’s side, firmer on James’.
“It’s honestly the best thing we’ve bought for our relationship,” she added.
Who Should Consider Buying a Bigger King in the UK?
While not everyone has the square footage of a country estate, a bigger king mattress isn’t reserved for the ultra-wealthy or those with enormous bedrooms. It’s actually a smart, practical upgrade for a wide range of people. Couples who value personal space, restless sleepers, families with young children who occasionally share the bed, and even pet owners can all benefit.
If you or your partner struggle with disrupted sleep due to tossing, turning, or simply feeling cramped, this extra surface area could be a game changer. Even in smaller UK bedrooms, opting for a bespoke or modular version of a bigger king allows you to enjoy the added comfort without sacrificing layout or flow.
What to Look for in a Bigger King Mattress
Before you go all in, make sure you’re choosing the right features:
Material quality: Look for high-density memory foam or hybrid coils
Firmness options: Consider dual firmness zones for couples
Cooling layers: Bigger beds trap more heat; breathable fabrics and gel-infused foam help
Edge support: Prevents the mattress from sinking at the sides
Motion isolation: Essential if one or both of you moves a lot
And of course, check delivery logistics will it fit through your stairs or hallway? Luxe Mattresses offers home consultations and delivery guidance to help with this.
Final Thoughts: Is Sleep Independence the New Couple’s Goal?
We all love the idea of closeness, but modern couples are learning that closeness in a relationship doesn’t require physical crowding in bed.
A bigger king mattress is not just a product, it’s a personal investment in your health, relationship, and mental wellbeing. From better sleep posture and motion isolation to custom firmness and cooling comfort, it provides a true upgrade to how we rest, recover, and reconnect.
And if you’re still clinging to the edge of a double bed wondering why you’re always exhausted, maybe it’s time to stretch out – literally.
