I tested the royal mattress that's fit for King Charles – here's my thoughts & expert tips to keep cool on summer nights

KING Charles is hardly going to sleep on an IKEA mattress - and luckily, I was able to experience a truly regal sleep experience that's fit for the royals.
The Sleepeezee Regency Kennington 4200 Pocket Sprung Mattress holds the prestigious Royal Warrant of HM King Charles III, a mark of quality and excellence.
And thankfully, I managed to get my hands on the posh mattress - which certainly doesn't come cheap.
The pricey buy, which will set shoppers back an eye-watering £1,199 for a Single, £1,499 for a Double, £1,699 for a King and just under £2,000 for a Super King, is sure to burn a hole in your wallet, but is it worth it?
Would it be magic or a money pit? Here, I put it to the test.
After hearing that this Sleepeezee mattress, which has carried the Royal Warrant of HM King Charles III for over 60 years, is made with 'naturally breathable and cooling bamboo and certified British wool,' to ensure exquisite comfort, I knew I had to give it a try.
So forget counting sheep or scrolling through YouTube desperate for relaxing ASMR videos when you next can't sleep - you'll have to count your money if you dream of having one of these mattresses in your home.
As someone who exercises (or at least, tries to) several times a week while working full-time, I need a mattress that will let me sleep easily.
And to add a slipped disc and chronic back pain to the mix, could this mattress give me the restorative sleep I needed to tackle everything?
Here, I share my honest thoughts on the Sleepeezee, as I reveal whether it's worth the splurge.
While the mattress world is a minefield of options - this buy, which you can buy from Dreams store, has been a hit online so far, with numerous five star reviews and an average rating of 4.8 out of five.
Comments describe it as 'so comfortable' and it is said to provide 'wonderful sleep,' but would it really offer Buckingham Palace -quality rest every evening?

First impressions
First things first, this mattress is HEAVY.
Thankfully, I had it delivered by pros, but it's worth noting it would definitely be a challenge to move by yourself.
However, once it was on my bed, things were super smooth-sailing.
The mattress has 2,306 pocket springs and is said to be 'medium comfort grade for all-round support.'
As well as layers of ultra-supportive mini springs, it also has a sumptuous pillow top.
And that's not all, as it's also got antibacterial bamboo woven through the plush pillow top surface, ensuring your mattress stays fresh.
So...does it deliver?
And for those looking for an out of this world sleep, this mattress could be just the thing for you.
It's a great mattress and albeit expensive, if you ask me, it's well worth the investment.
Not only have I woken up feeling well rested this last fortnight, but I'd even go as far to say I've actually had the best two weeks of sleep I've had in a very long time.
Rather than spending hours of an evening chilling on the sofa, I can't wait to get into bed

It's genuinely one of the most comfortable mattresses I have ever slept on and I don't think I've ever slept so deeply and fallen asleep so quickly (the latter being something I often struggle to do).
Now, rather than spending hours of an evening chilling on the sofa, I can't wait to get into bed.
It really is like sleeping in a cloud and as well as being incredibly comfy, it moulds to the body, meaning I can catch Zs in any position.
And thanks to the wool and bamboo in this mattress, it is said to work to regulate your temperature throughout the night.
Benefits of the Sleepeezee Regency mattresses
SO, why is this mattress better than the best?
Hannah Hayden, a Junior Buyer at Dreams, has revealed why the Sleepeezee Regency mattresses are ones you won't want to miss.
Hannah tells Fabulous: 'Each mattress in the Sleepeezee Regency range is handcrafted in Kent and features the timeless support of individually encased pocket springs, with options ranging from 1,600 springs in the Kenilworth mattress, 2,800 in the Kew mattress, to 4,200 in the Kennington mattress.
'These are paired with layers of naturally breathable bamboo and certified British wool, working together to regulate your temperature throughout the night.
'That makes a big difference in helping you stay cool, calm, and comfortable instead of tossing and turning – especially during this hot weather.
'Each mattress is infused with antibacterial bamboo, adding an extra layer of softness while also helping to keep the mattress fresher for longer.
'It's especially useful for allergy-prone sleepers who need a clean, healthy sleep environment.
'With a layer of adaptive pocket springs, these mattresses provide targeted support exactly where you need it while minimising movement transfer, so you're less likely to be disturbed by a restless partner.
'For extra peace of mind, every mattress in the Regency range comes with a 10-year manufacturer's guarantee, a 100-night Comfort Guarantee, and the prestigious Royal Warrant of HM King Charles III, a true mark of exceptional British craftsmanship and quality.'
I can't say that I haven't had sweaty nights in this past fornight, but then again, the temperatures in the UK have been quite wild recently.
Overall, yes this nine-layer mattress is expensive, but you can't expect top notch quality at bargain prices, right?
Experts advise that mattresses should be replaced every eight years, so although forking out for this is sure to make anyone's bank account wince, if you're feeling lost in a sea of memory foam, springs and hybrids, I'm sure you'll sleep easy once this lavish buy is in your bedroom.
So if you've been tossing and turning on the same mattress for over a decade and have noticed it's got more lumps than a badly stirred gravy, it may just be the time to upgrade.
My rating: 5/5

Keep yourself cool when you sleep this summer
And if you're keen to know more about ways to stay cool this summer, we've got you covered.
Not only does this mattress work to help you feel cool, but Sammy Margo, a Dreams Sleep Expert and a Chartered Physiotherapist for 32 years, here shares her top eight tips to battle the heat during summer nights.
Hang a wet sheet in front of your window
If you find yourself tossing and turning at night as the temperature rises, Sammy reveals why a damp sheet could be your saviour.
The sleep pro explains: 'Dampen a sheet with cold water and hang it in front of your open window.
'The breeze will blow through the sheet and cool down your room.'
Put your beauty bits in the fridge
Secondly, Sammy reveals why keeping your beauty products in a make-up bag is a big mistake.
She says: 'If you use beauty products such as facial sprays, toners, or moisturisers, consider storing them in the fridge.
'Applying chilled products to your skin can help soothe and refresh you, especially on hot and sticky nights. Plus, it can feel like a mini spa treatment before bed.'
The best sleep routine and environment
Thomas Høegh Reisenhus, TEMPUR® sleep specialist & sleep counsellor, reveals the key components of a good bedtime routine and environment...
A sure-fire way to facilitate a better night's sleep is to practice good sleep hygiene.
Establish a sleep routine that works for you and stick to it.
This will help your body establish a consistent, natural sleep-wake cycle which can do wonders for your overall sleep quality.
As such, try to avoid making up for lost sleep with a lie-in.
Instead of sleeping in, spend your morning reading a book in bed or having a leisurely coffee in the kitchen.
Ensure that your bedroom, bedding, and sleepwear are fit for purpose too.
The ideal sleep environment is dark, quiet, and cool – much like a cave.
If you find unwelcome sources of light are keeping you up, consider investing in an eye mask or black-out curtains.
Adding soft furnishings can be a great way to reduce noise, with the surfaces having an absorptive quality, but if this doesn't work, consider embracing a soothing soundtrack to block it out.
In terms of temperature, try to keep your bedroom at 18°C. You can further reduce the risk of waking up due to overheating by ensuring that all your bedding and sleepwear is made with natural, breathable materials such as cotton and linen.
Bear in mind that everyone is different; what might work for most, may not work for you!
Whilst knowing how much sleep you should get, how to overcome common barriers, and practicing good sleep hygiene can facilitate a great night's sleep, if you continue to struggle with sleep or fatigue persistently, do not hesitate to visit a doctor or health professional for support.
Try a cold-water bottle
Additionally, Sammy shares the hot water bottle hack you'll need to try, as she advises: 'Fill a hot water bottle with cold water and put it in the freezer for a few hours before bed.
'Then, place it at your feet or other cool parts of your body to help you fall asleep.'
Keep a spoon nearby
Not only this, but you'll want to keep a spoon by your bed if you're desperate for a good night's sleep, as Sammy recommends: 'Consider keeping a cold metal object, such as a spoon or a pan, within reach on your bedside table.
'Using this object to cool down specific areas of your body, such as your wrists or neck, before bed can help you feel more comfortable and refreshed.
'Plus, having it nearby means you can easily grab it during the night if you need a quick cool-down.'
Freeze your sheets
As well as hanging a wet sheet in front of your window, you'll need to keep the bedding on your bed chilly too, as Sammy says: 'Put your sheets and pillowcases in a plastic bag and stick them in the freezer for a few hours before bed.
'This can create a cool and refreshing sleeping surface.'
Use cooling bedding
Not only this, but if you're really struggling with the heat, you may also want to consider investing in cooling bedding.
Sammy shares: 'Look for bedding made with breathable materials, such as bamboo or cotton, that can help regulate body temperature.
'Additionally, there are special cooling bedding products, such as the TheraPur Cool Mattress Protector, TheraPur ActiGel® Glacier 1800 Combination Mattress and TheraPur Cool Fibre Pillow Pair - just to name a few - that are designed to stay cool and promote a comfortable sleep environment.'
Make a DIY air conditioner
But if you're looking for a more affordable alternative, why not make your own DIY air conditioner?
Sammy shares her tried-and-tested trick, as she explains: 'Fill a shallow bowl with ice and place it in front of a fan.
'The air blowing over the ice will create a cool breeze that can help lower the temperature in your room.'
Sleep solo
And if you thought that was it, think again, as Sammy concludes: 'If you usually share a bed, consider sleeping alone during a heatwave.
'This can help prevent body heat from building up and making you even hotter.'
