Corovin Duvets: Easy-Care, Hypoallergenic Warmth at an Honest Price
Some blankets are bought just to look nice. Others are bought because they actually work. Corovin blankets are definitely in the second group, and they do a really great job at it.
Our Corovin blankets start at less than £10 and come in four different warmth levels, from a light 4.5 tog all the way up to a heavy 15 tog. They're filled with hypoallergenic hollow fiber, stitched in channels so the filling doesn't move around, and you can throw them straight into the washing machine. Our product pages say they're made in the UK and follow British Standard 5335. If you're looking for a practical, easy-to-care-for blanket that doesn't cost a lot of money and doesn't need special treatment, this is the perfect choice for you.
What Is a Corovin Duvet?
Corovin is a brand name for a special kind of fabric made from polypropylene that isn't woven like regular cloth. Instead of weaving threads together the way you'd make cotton fabric, it's created by bonding tiny fibers into a thin but tough sheet. You'll find this material used as the outside layer of certain duvets, which is why some stores call them "polypropylene duvets".
Underneath that outer layer is a hollow fiber filling. Each tiny fiber has a small air passage running down the center, and this air passage keeps heat trapped inside without making the duvet heavy. The whole duvet is stitched with channel stitching, which means it has long lines of stitches sewn through it so the filling stays in place and doesn't bunch up at one end while you sleep.
Here's something that gets confusing on websites a lot: the outside covering is made of polypropylene, but the filling inside is made of polyester. These are actually two completely different materials that each do their own important job.
Why Choose a Corovin Duvet?
It's hypoallergenic: There's no feather or down inside, so nothing for a feather-sensitive sleeper to react to. That's a big part of why people with allergies pick synthetic bedding.
It's easy to look after: Machine washable, and fine on a low tumble dry. No specialist cleaning, no worrying about a label.
It's made in the UK: Not a detail you'll find on every budget duvet.
It's light. The filling gives you loft without heaviness, so even the warmer togs don't feel like sleeping under a pile of bricks.
It's genuinely affordable: Prices run from under £10 to just over £13 on the listings we checked, which makes it a practical choice when you're kitting out more than one bed.
Corovin vs Poly Cotton vs Microfibre
All three of our synthetic duvet ranges use a hollow fibre filling, but the outer fabric is what sets them apart. The choice of fabric affects how each duvet feels against the skin, as well as its price.
The Corovin range, made with a non-woven polypropylene outer, is the most affordable option and is well suited to everyday use. For a softer feel with the texture of woven fabric, the Poly Cotton range combines a poly cotton outer with the same hollow fibre filling. If you prefer a smoother, silkier finish, the Microfibre range offers a soft feel against the skin while keeping the benefits of synthetic filling.
In simple terms, choose Corovin for affordability and easy care, Poly Cotton for a softer woven feel, or Microfibre for a silky finish.Corovin's outer has a lighter, slightly crisper feel than a woven fabric. Most people never notice, because the duvet lives inside a duvet cover. If touch matters to you, step up to poly cotton or microfibre. If value and easy washing matter most, Corovin is hard to beat.
What to Expect From a Corovin Duvet (and What Not To)
Let's be real about what you're getting, because it helps avoid being let down later.Look for a light, warm, easy-to-wash duvet that works great night after night. Look for channel stitching that spreads the warmth evenly, and a price that lets you spend money on a nice duvet cover and pillows too.
Don't look for the super soft, fluffy feeling of goose down or the smooth feel of microfibre. Corovin is a practical material, and that's why it's made this way. It gives up a little bit of softness to be tougher and cost less. Bedding that lasts longer also means you don't have to buy new stuff as often, which is good for your money and also good for the planet.

Choosing the Right Tog
Tog is simply a measure of warmth. Higher means warmer.
Corovin summer duvet: the 4.5 tog is the lightest option. It suits warm bedrooms, hot sleepers and the odd stuffy July night.
All-rounder: the 10.5 tog covers spring, autumn and most of winter. Only buying one? Start here.
Winter: the 13.5 tog is for cold bedrooms and people who feel the chill.
Coldest nights: the 15 tog is our warmest. It's the one for draughty older houses and anyone who wakes up cold.
Unsure between two? Think about the coldest three months of your year, not an average night.
Corovin Duvet Sizes
The same construction is used across every size, with each duvet scaled to provide the right fit for different beds. A Single duvet (135cm x 200cm) is ideal for single beds and children’s rooms. A Double duvet (200cm x 200cm) suits most couples and shared beds, while a King duvet (225cm x 220cm) is designed for king-size beds or provides extra drape when used on a double bed. For the largest UK beds, the Super King duvet (260cm x 220cm) offers the most generous coverage.
Measure your mattress rather than guessing from the bed frame. A size up, such as a king on a double bed, gives a generous drape and stops the covers wandering. Browse more sizes in Super King Size Duvets or the full Duvet Collection.

Corovin Duvets for Guest Rooms, Holiday Lets and Kids' Beds
Corovin works really well in places where bedding gets used a lot and washed frequently. This includes guest rooms, vacation rentals, rental homes, college dorm rooms, and kids' beds. It's perfect for anywhere you need a dependable duvet that you can wash and put right back on the bed the same day.
If you want something practical like what hotels use, this is exactly what you'll get: steady warmth, easy to take care of, and fair prices. If you're looking for that natural, cozy hotel feeling, our feather options are a better choice. We'd rather help you find the right duvet than try to sell you something that isn't the best fit.
Are Corovin Duvets Good for Allergies?
These are a really popular choice, and it's easy to see why. Since there's no feather or down stuffed inside, people who are sensitive to feathers won't have any problems sleeping on them.
Two important things to know. Hypoallergenic just means it's less likely to make you have a reaction, but it's not a cure or medical treatment. Also, dust mites can get into any kind of bedding, so you need to wash it regularly and let it air out. If you have eczema, asthma, or an allergy that a doctor confirmed, you should talk to your doctor or pharmacist about what bedding would be best for you.
How to Care for a Corovin Duvet
Our Corovin duvets are machine washable and suit a tumble dry on a low heat.
Check the label: Then wash in a large-capacity machine if you can. A duvet squashed into a small drum won't rinse properly.
Go gentle: A delicate cycle and mild detergent are plenty. Skip the fabric softener, which can coat the fibres and flatten the loft.
Dry it fully: Low heat, with a couple of dryer balls if you have them. Shake it out halfway through. Never put it away damp, or you'll get that musty smell.
Use a cover: A washable duvet cover takes the daily wear, so the duvet itself needs washing only once or twice a year.
How to Choose the Best Corovin Duvet
A quick checklist:
- Tog: choose for your bedroom and how you sleep, not the coldest night you remember.
- Size: measure the mattress first.
- Construction: look for channel stitching, which keeps the filling evenly spread.
- Care: confirm it's machine washable.
- Returns: check the policy. Ours covers regular-priced items for 30 days.
