Simba 3-in-1 Duvet review: one duvet to rule them all?

The Sun

5 days ago

A 3-in-1 duvet bundles two separate layers you can use on their own or fasten together, giving you three tog options in one — light for warm nights, medium for in-between weather, and a thicker combo when the temperature drops.
Smart, space-saving, and in theory, ideal for year-round comfort.

The catch? At £349 for a double, Simba's version sits firmly at the premium end.
I put it to the test for this Simba 3-in-1 Duvet review to find out if it's a clever investment or a costly gimmick.
As someone who prefers a cooler bedroom, I was curious — should you add more just because you can?
There are thoughtful touches here, from easy-to-swap layers to more eco-conscious materials, with the fill made from recycled plastic bottles and a Better Cotton cover.
On paper, it's everything you need in one package. The question is whether it feels as good in bed as it looks on the spec sheet.

How I tested the Simba 3-in-1 Duvet
I'm certainly no stranger when it comes to Simba products.
I've had a Simba mattress for the last 10 years, and it transformed my sleep from being an insomniac to achieving a sleep score over 80 every single night. My Simba APEX Mattress is probably one of my most prized possessions.
That means I came into this Simba 3-in-1 Duvet review with high expectations.
Simba Hybrid 3-in-1 Duvet review: Quickfire Q&A
How much is the Simba Hybrid 3-in-1 Duvet? Brace yourself — prices start at £249 for a single and rise to £449 for a superking. Simba does run regular sales, however, so you should be able to pick it up for less during sales events.
Which way up does the Simba Duvet go? Either side works—choose the layer you need, pop them together if required, and keep the cover's closure at the foot.
Can you wash it? Yep, it's machine washable, but good luck fitting it into your home washing machine.
Who's it best for? Individuals who struggle to regulate their body temperature and sleep patterns throughout the year. With the UK's weather as unpredictable as it is, it's nice to be able to whip off a layer and still sleep peacefully.
What we loved: I loved the softness and quality feel of the duvet. It's warm but still feels lightweight and non-restrictive.
What we didn't: The price. And if we're nit-picking, the buttons can be a little fiddly, but it's not a deal-breaker.

First impressions
Luckily, the delivery process from Simba is very straightforward. At the time of writing, Simba uses DPD Local for its non-mattress products.
Unpacking the boxes is easy, and getting the duvets ready to go is a piece of cake.
The duvet comes with a storage case, which I used to store the half of the duvet that I wasn't sleeping with.
However, I found it wasn't much of a space saver, as it took up the same amount of space under my ottoman bed as any other duvet would.
As I had hoped, though, Simba's 3-in-1 duvet felt premium right away.
It's got a soft cotton cover, which still feels quality beneath a bedsheet, and the 'renew clusters' in the filling, which are made from recycled plastic, are evenly distributed and divided into pockets so they can't form clumps.

Does it deliver?
I tested this duvet in the summer and mostly used it with its lightest 3.5 tog (blue binding), which I didn't find unbearable, even in the middle of a heatwave.
That could be down to the duvet's moisture-wicking properties, which help it draw sweat away as you sleep.
Simba has always been great at incorporating cooling tech into its products, and the duvet seems to be no exception.
The spring/autumn duvet (grey binding) is a 7-tog covering, and I'd back up Simba's claim that it's suitable for the majority of the year.
This is the one that I gravitated towards the most.
Similar to the light summer duvet, the 7 tog feels luxurious and is incredibly soft.
Combine the two duvets and (you maths whizzes guessed it), you get a 10.5 tog duvet designed for cold winter nights.
Given the premium design and the options available, I'm surprised to find someone who wouldn't like at least one of the options year-round.
How much does the Simba 3-in-1 Duvet cost?
The price is the biggest hurdle for the Simba 3-in-1 duvet.
At the time of writing, its RRP on the Simba website for a single is £249.
That's just too much, in my opinion. A quick search of the web reveals that you can find something similar for well under £50 elsewhere.
However, Simba often has discounts, so if you can nab one during a sale, it's more than worth it — we've seen it go as low as £186.75 during sale periods.
Simba distinguishes itself from rival brands with its premium quality, eco credentials and carbon-neutral delivery, but even with these positives, I felt that £449 (RRP) is a steep price for a Super King duvet.
In my experience, internet mattress brands are notorious for having killer sales during peak periods, so you should be able to find this 3-in-1 duvet at a discount in the near future.
We'll update this page with offers on this duvet when we spot them.
Can you wash a Simba 3-in-1 Duvet?
Yes, the Simba 3-in-1 duvet is machine washable, and I'm reassured by Simba's claim that the duvet will retain its softness and shape even after repeated washes.
I can tell from the off that it isn't going to fit in a standard drum, so it'll require a trip to the local laundrette..
Of course, I'll let you know when the time comes for a laundry cycle.
Where to buy the Simba 3-in-1 Duvet
You can buy Simba products from several retailers as well as the official website.
I've listed some of the options we've seen below.
What's the difference between the Simba 3-in-1 Duvet and the Simba Hybrid Duvet?
The two duvets Simba offers at the time of writing are similar in quality.
They're both made from a mixture of Better Cotton and recycled plastic, they both feel luxurious, and they're both temperature-regulating.
But the standard Hybrid Duvet is a 10.5 tog cover, whereas you get three options with the 3-in-1: 3.5 tog, 7 tog and 10.5 tog.
Simba 3-in-1 Duvet alternatives
Not sold on the price? There are plenty of Simba 3-in-1 Duvet alternatives worth a look.
For a similar mix-and-match setup, consider standard all-seasons sets (a 4.5 tog and a 9 tog that can be buttoned together) from Silentnight, Dunelm, or Dusk, which offer year-round flexibility for less.
Hot sleeper? Panda's bamboo Cloud Duvet is breathable, hypoallergenic and feels light and floaty.
If your temperature swings through the night, Woolroom's British wool duvets naturally regulate heat and moisture, keeping things comfy in every season.
Prefer that plush down feel without feathers? Soak & Sleep's Soft As Down microfibre range offers impressive loft with an all-seasons bundle.
Still like Simba tech but want simpler? The Simba Hybrid Duvet is a single-layer option with cooling tech and easy care.
Premium seekers can step up to Hungarian goose down all-seasons sets at retailers like John Lewis—luxurious, warm and long-lasting if properly cared for.
The Verdict: is a Simba 3-in-1 Duvet worth the money?
If you're willing to spend the money on a Simba 3-in-1 Duvet, I don't think you would be disappointed
It does everything you'd hope it would and feels luxurious doing so. It's also incredibly practical and should last a long time.
I also appreciate Simba's commitment to environmentally friendly manufacturing and delivery.
But would I spend my own money on this duvet? Short answer, no — but when it's on sale, I could be swayed.
I'd say to keep your eyes peeled for deals on this duvet around Black Friday and Christmas if you feel like treating yourself.
