Simba Hybrid 3-in-1 Duvet Review (King Size)
I’ve been lucky enough to test & review some flagship items from the Simba Mattress collection over the past year, including the Simba Ludlow King Size Bed and the Simba Hybrid Original Mattress. This month I’m sharing my thoughts on another exciting product from the range: the Simba Hybrid 3-in-1 Duvet (king size). Thanks Simba Sleep team! This duvet held special appeal for me, as someone who changes duvet according to the season. We also pay the dry cleaners to clean our extra thick winter duvet for us, as it doesn’t fit in our washing machine. The Simba Hybrid 3-in1 Duvet seems the perfect solution; a clever snap-together design which can easily be toggled for your warmth preference or weather, and which can be machine washed at home, saving travel & dry-cleaning costs as well as time. Read on to find out how we got on with this ingeniously versatile duvet from Simba!

As someone who struggles to regulate a comfortable body temperature at nights, thanks to perimenopause (hot flushes/night sweats) as well as the changeable British weather, the Simba Hybrid 3-in-1 Duvet appealed from the start. A duvet which can offer very lightweight, medium-weight or combine for the heaviest, warmest tog, seemed a duvet dream come true. Not only is this Simba duvet versatile in its weight/warmth offerings, the two layers (which can be ‘snapped’ together or used separately to provide the three usage options) are also machine washable. There are many other benefits to this luxurious duvet too, beyond these top priority & most obvious ones.
However, we must talk about the price of this king size duvet. I know, “it’s almost £400!” I hear you cry, incredulously. I know this, because before it arrived, I too was bewildered at how a king-sized duvet could possibly be worth a price tag of almost £400. Ehh, I can’t make the price sound any better I’m afraid. All I can say, is that after using the Simba Hybrid 3-in-1 Duvet for several months now, I would consider it a sound investment if you’re looking for a year-round, top-quality duvet which will likely last a lifetime.
Would I buy it myself? Surprisingly, after a few months of use… yes, I absolutely would. And I didn’t expect that to be the case before it arrived.
Let me start at the beginning, then once you read through my experiences with this almost-magical duvet, you can make your own mind up.
Duvet Delivery (& Packaging)
As always, dispatch & delivery notifications from the Simba team were provided quickly and were easy to follow. My new duvet was dispatched via DPD, who provided a one-hour timeslot for delivery and were punctual, then friendly upon arrival.
The duvet was contained in a zip-up Simba storage bag, inside the outer mailing bag packaging. Opening this zip-up storage bag revealed our new, luxurious duvet (well, duvets, really) and an information card.
Video
I hope you enjoy my short video of the Simba Hybrid 3-in-1 Duvet below, showing unboxing, the included information, the storage bag, how the duvet sits when first on the bed, me randomly throwing a heavy dildo on it (!) and how the popper fasteners snap together firmly and are undone (which I promise is much easier with two hands, rather than just one while you’re videoing the process):
Usage Options & Set-Up
As mentioned earlier, there are (unsurprisingly!) three different duvet options available to you with the Simba Hybrid 3-in-1 Duvet:
- 3.5 tog – the lightest weight, ideal for hot weather and summer (with blue edging)
- 7 tog – great for those chillier days in early spring/autumn (with grey edging)
- Combine the two to create a 10.5 tog heaviest weight duvet, with the additional benefit of layering to provide cosy warmth through the coldest nights. Because of all the layers, this option provides more warmth and cosiness than your run-of-the-mill 10.5 tog duvet, so don’t be deceived into thinking it can’t be warm enough.
When using the two separate duvets together as the thickest/warmest option, you need to snap them together using the sturdy popper fasteners you find along the edges of the duvet. The popper fasteners are sturdy, like I say – they don’t pop back open and have withstood many nights of my husband and I tossing and turning in bed without separation issues. The duvet survived intact as well (!)
Material & Care
The Simba Hybrid 3-in-1 Duvet is made of ‘Simba Renew’ airy filler, contained in a smooth cotton cover which is blended with modal fibres to assist air flow. The Simba Renew filler inside the duvets is soft and down-like. It’s eco-friendly too, as it’s made from recycled plastic bottle fibres, combed into light, downy clusters, blended with 20% modal for sublime warmth and comfort. Modal is a semi-synthetic fabric made from beech tree cellulose that is used for clothing and household items.
Both duvet layers which make up the Simba Hybrid 3-in-1 Duvet are machine washable, if your machine is large enough of course (min. 8kg capacity load). We wash ours at max 30°C, then it can be hung to dry (over the top of the banister is a favourite in winter) or even tumble dried on a low heat setting.
Full care details and washing instructions can be found in the FAQ on the Simba Sleep website. Helpfully, there’s a QR code on the edge of the duvet leading to Simba’s recycling & care advice – these labels also help to indicate you’ve got the duvet the right way round on your bed!
I love how the layers that make up the Simba Hybrid 3-in-1 Duvet are stitched. Instead of the old-fashioned and unhelpful design where all the filling is just in one huge area with just the sides stitched up, Simba have contained their Simba Renew filling in rows of stitched pockets. This means that the filling remains a consistent, warm layer throughout the duvet, no matter how many times it’s moved, or how roughly, through the night. Plus, if you’ve ever washed a single duvet at home (we can’t fit our old king size one in the washing machine as mentioned earlier) you’ll understand how frustrating it is trying to redistribute the filling after it all bunches up in one end. I’ve had duvets which were simply never the same again after a wash, due to the filling splitting up and balling in the ends, or all just at one end, rendering the duvet useless. The stitched pockets design is clever, practical, and is another directly helpful quality feature of the Simba Hybrid 3-in-1 Duvet.
Versatility
There are so many top-quality features and eco-conscious, ethical choices which make up the Simba Hybrid 3-in-1 Duvet that it’s difficult to cover them all in one brief blog review. The stand-out feature, for me, is versatility. The ability to transform this Simba product into a multi-layered, lightweight but cosy and warm winter duvet, or the lightest tog ‘hot summer nights’ covering, or the medium tog for those chillier nights, is incomparable in my experience.
It’s so easy to do as well, thanks to the popper fastenings. You might think that these would easily detach and come apart during nightly movement, but we haven’t had one popper come undone through our several months of use. They fasten very firmly and don’t pull apart accidentally.
As we have been using the Simba Hybrid 3-in-1 Duvet through the colder months of the year – the end of autumn 2024 and through the winter season into 2025 – we haven’t used the duvet layers separately as yet. However, I have connected then separated the layers to see how easy it is to do, and how simple it is to put them back together. Because of the helpful labels on the duvet layers, you always know which way round to put the duvet in your duvet cover, then on your bed. The tag actually shows an arrow pointing to the foot of a bed to indicate which way round it goes. Brilliant!
The First Night
When we first received the Simba Hybrid 3-in-1 Duvet, early October 2024, I was a little concerned upon taking it out of the storage bag for the very first time. The duvet felt slightly crinkly and quite lightweight, overall, for a top-quality, luxurious duvet. My husband and I snapped the two layers together to form the heaviest weight winter duvet and put it in one of our king-size duvet covers, changing the rest of the bed linen to match in the process, then left it on our bed ready for use that night.
By the time bedtime rolled around and I climbed into bed, I was amazed at how much the duvet had ‘fluffed up’ since we first unpackaged it earlier that day. The Simba Renew filling had clearly benefitted from being left to rise, out of the packaging constraints and on our bed, for the majority of the day. A big relief. The covering of the Simba duvet, felt through our duvet cover, still felt a little crinkly to me through the cover fabric, but softer than when I first laid hands on it. I kept in mind all the benefits of the duvet I’d read about on the product page at Simba Sleep, and eventually drifted off into a restful sleep under our new duvet.
Waking the next morning, I realised something. I hadn’t been as hot in the night! Well, my perimenopausal body had done its thing of night sweats and hot flushes through the night as usual, but the duvet had somehow (via its temperature-regulating Stratos, apparently) kept any horrible consequence of this to a minimum. With our old duvet, particularly the heavier weight one for autumn & winter, my nightly hot flushes would often lead me to waking in clammy or actively wet surrounds, the duvet damp to the touch and with myself caught in a hellish horror of hot flush contained in a heavyweight winter duvet which soaked up yet caused ever more sweating. The Simba Hybrid 3-in-1 Duvet wasn’t damp at all – and even more amazingly, I hadn’t woken up in the night feeling like I was drowning in a perimenopausal hot flush hell.
Ok, I thought. I can’t hope to get my head around all the tech that has gone into making this (admittedly costly) Simba duvet. But whatever all that tech is, it works. And isn’t that what we all care about, at the end of the day? Something that does what it promises to do?
I was beginning to see why this duvet has such an initially shocking high price tag. If that first night wasn’t just a lucky blip, if this truly was a menopause-friendly, year-round duvet solution built to last, I would have happily paid the £400 price tag myself. Before experiencing it for myself, though, I could never have imagined saying such a thing.
Continued Use (Autumn & Winter)
Happily, that first night wasn’t just a lucky blip. I could never go back to any other bog-standard duvet now I’ve experienced the ingenious temperature-regulating tech, the cosy luxury, the easy year-round versatility and the convenient wash-at-home capability the Simba Hybrid 3-in-1 Duvet offers.
During extended use throughout October, November and December, into the start of January 2025, I have found that the initial crinkliness of the uppermost layer of the duvet has softened. Almost like it has been ‘broken in’, where the Simba duvet has been through rigorous use, doing its job keeping my husband and I warm and cosy enough through the nights while the temperature-regulating tech prevents sweaty-mess hell. I now wake every morning after the best nights’ sleeps I’ve had for a long time, because I’m not waking up with a cold, wet duvet trapping my miserable, perimenopausal body. Unfortunately, it hasn’t done away with my bladder’s requests to visit the loo several times a night, but duvet tech has its limits I suppose.
I genuinely love waking in the morning cuddled up to this duvet. I didn’t even know I needed it in my life, but now it’s here, I absolutely love it. It’s just perfect.
As mentioned above, my husband and I have been enjoying the Simba Hybrid 3-in-1 Duvet through autumn and winter. Therefore, I have been unable to share my thoughts on using the lightest weight layer of this duvet to help us enjoy restful sleep through hot summer nights. Later this year, once the weather warms up, I plan to return to this review and update with how this duvet handles the terrible twosome of hot flushes and heatwaves.

Final Thoughts
Would I recommend the Simba Hybrid 3-in-1 Duvet? Absolutely.
Is it worth the £400 price tag (for the king size option)? Strangely enough (and I never thought I’d be saying this) yes, it is. What makes the price easier to swallow is the fact Simba offer payment instalment options, so I would opt to pay it off monthly for a year (instalments are subject to application). For the king size duvet we have, this works out at just over £33 a month for 12-months.
There’s just so much to recommend this duvet it’s difficult to cover all its brilliant facets adequately in one review. Here are the features we love the most:
Versatility: You get a heavy winter-weight duvet, a medium spring/autumn duvet and a lightest weight summer duvet which can be toggled easily whenever you wish.
Machine-washable: the components are machine washable, saving on dry cleaning fees and extra travel expenses. You can even tumble dry on a low heat setting if you don’t have room to hang to dry.
Temperature-regulating tech: I still think it’s magical how this duvet has done away with my waking in a hot flush/cold clammy perimenopausal hell in the nights, surrounded by a damp duvet. The Simba Hybrid 3-in-1 maximises air flow which means that although I still get hot flushes in the night, it’s just me that’s affected, not the duvet. It isn’t disgustingly soggy and unusable. Plus, my nightly hot flushes have calmed since using this duvet. Magical.
Stitched pockets: The clever design of both layers making up this versatile duvet means that the filling remains consistent throughout, even through washing and drying. This is unlike traditional duvets, where the filling often bunches into balls or down one end through rigorous use or after it’s been in the washing machine.
Thoughtful labelling: If you’ve ever been confused about which way round your duvet goes mid bed linen change (this tends to happen more with double or king size beds), you’ll be delighted to hear Simba have solved this problem, too. There are clever labels on the ends of the duvet layers which give clear instructions which way round it goes on your bed.
Feels luxurious and cosy: Quite apart from all the techy and eco-conscious details which make up this brilliant sleep accessory, it simply feels fantastic. It’s cosy and warm without being suffocating or clammy; you can tell it is a top-quality duvet which will last through many years of use.
Comes with storage: The Simba Hybrid 3-in-1 Duvet comes with a zip-up Simba branded storage bag which is useful to keep one of the layers in if you’re only using the lightest weight or the medium weight layer, depending on the season. If using both layers together, the bag easily folds up and you can pop it in a drawer or under the bed until you need to use it.
Pay in instalments: If you can’t pay the full price right away, the Simba Hybrid 3-in-1 Duvet is still accessible to you. Simba offer a pay-in-instalments option which makes the price tag a little easier to bear, when spread over 12-months.
