Tom's Guide Verdict
In our experience, the Larke Nature's Blend duvet delivers excellent breathability and comfort. Made using natural tree fibre filling and pure cotton, the lightweight duvet is hypoallergenic and easy to maintain, since it's washing machine and tumble-dry-friendly. The biggest drawback is the luxury price tag; this duvet starts at £120 for a single size. But the added benefits, and quality sleep it helps you achieve, make it worth every penny.

Larke Nature's Blend Duvet: Review in brief
Can sustainability and comfort go hand in hand? Larke has proved it's possible with their Nature's Blend duvet, crafted using breathable eucalyptus tree fibres and pure cotton.
The duvet, which is OEKO-TEX and FSC certified, is made to feel luxuriously comfortable no matter the season. It has a lightweight build with pretty seashell-inspired stitching and holds its shape well, even if you're someone prone to tossing and turning during the night.
Thanks to the natural materials, it's also naturally hypoallergenic and temperature-regulating — features that could earn it a spot in our best duvets guide. You can choose from three tog ratings (4.5, 10.5 and 13.5) and four sizes (single, double, king and super king) to suit your bed dimensions and comfort preferences.
While in our tester's experience, it delivered on the promise of luxury comfort and breathability, very hot sleepers should look for duvets with more actively cooling elements, which can prevent night sweats and help you stay cool.
That's the summary of our findings. Scroll down to know about the Larke Nature's Blend duvet in detail:

The prices for each size vary according to the tog rating you opt for. You can choose from three options: 4.5, 10.5 or 13.5 tog, with the price increasing the higher the tog rating.
For reference, the all-season Nectar Duvet is 10.5 tog and starts from £49 for a single size (read the full Nectar Duvet review to know more details).
However, the Nature's Blend duvet comes with benefits like a 30-night trial period, five-year warranty covering manufacturing faults (stitching, filling and outer fabric issues except those due to normal wear and tear) and free delivery in the UK, which is excellent for bedding.
The brand also promises a full refund if you're not satisfied by the end of your 30-day trial period.
Larke Nature's Blend Duvet: Design and materials


The Larke Nature's Blend duvet is OEKO-TEX and FSC-certified (the former meaning it's free from harmful substances, and the latter indicating raw materials sourced from responsibly managed forests) and features a lightweight Tencel-Lyocell (which is eucalyptus tree fibre) filling. The outer shell, meanwhile, is made from 280 thread count, 100% pure cotton.
According to the brand, the moisture-wicking tree fibres provide temperature regulation, while the top cover adds a layer of soft-to-touch, breathable comfort. However, it's worth noting that the Larke is not going to feel like your typical fluffy down duvet.
For those who struggle with allergies, Larke also highlights that the duvet is naturally hypoallergenic and "free from dust mites and skin-irritating synthetics."
The Larke duvet comes in a lovely creamy white colour with seashell-inspired stitching, which ensure an even distribution of the fill at all times. The stitch design and the piped edges add to the overall premium look of the duvet.
Larke Nature's Blend Duvet: Performance
I tested a king-size Larke Nature's Blend duvet with a 10.5 tog rating, which, according to the brand, can be used all year round.
Let's take a closer look at how it performed during the month-long testing period:
Setup




The Larke Nature's Blend duvet arrived in a cardboard box, rolled and packed in a reusable, adjustable cloth bag. It does not require any expansion time, and there was no off-gassing smell once it was out of the bag.
I did, however, notice that it's flatter and less fluffy compared to the microfiber duvet I was using before.
Our score: 5 out of 5
Temperature regulation
I tested the 10.5 tog Larke Nature's Blend duvet during British springtime when temperatures fluctuated considerably over 24 hour periods; anywhere between 5℃ and 20℃ (41F and 68F).
It's useful to note that I'm someone who tends to sleep cold and goes to bed with cold feet (unless it's peak summer). I wore a pair of socks and breathable pyjamas during the testing period. I also used a top sheet, which helped me gauge the softness of the duvet's outer shell to some degree, while still creating a barrier in between.
The Larke duvet, however, surprised me with its temperature regulation. While I slept all night snugly, I never woke up due to stuffiness or discomfort, even when the temperature soared.
The initial doubts I had about its flatter build also disappeared when I realised how comfy it is, regardless of the weather.
That said, if you are a hot sleeper, Larke does not advertise this duvet as actively cooling, so it would be better to opt for a lower tog rating or consider cooling bedding.
Our score: 5 out of 5
Care and maintenance
Maintaining the Larke duvet seems like an easy task. The brand recommends washing it at 40℃ (104 F) using a gentle detergent and tumble-drying on a low heat setting or air-drying, laying it flat.
If air drying, I'll also suggest using a dehumidifier, which can speed up the process.
Trying to redistribute the fill evenly after washing a duvet can be a nightmare, but Larke underlines that no shaking is needed — thanks to the stitches made to hold its shape.
Our score: 5 out of 5
Should you buy the Larke Nature's Blend Duvet?
The Larke Nature's Blend duvet is designed to be hypoallergenic, breathable, lightweight and most importantly, durable.
We felt, after testing it, that it largely kept its promise. It looks beautiful draped on the bed, feels comfy and is easy to handle and maintain (no running to the dry cleaners).
The downside, in our opinion, is the price. If you're someone who values quality sleep and are able to stretch your bedding budget, the Larke Nature's Duvet is a great purchase that justifies the higher spend.
Plus, there is a safety net: if you're not satisfied after the 30-day trial period, you get a full refund.

Don't buy the Larke Nature's Duvet if...
❌You want a cheap duvet: Starting at £120 for a single size, the Larke duvet is a premium purchase.
