Explore Our Cotton Duvet Cover Collection

Slip into something a little more colourful with our cotton Duvet cover collection—where comfort meets creativity. From bold, mood-boosting prints to vintage-inspired florals and playful patterns, there’s a design to suit every bed and dreamer. Think sun-faded tones, expressive palettes, and limited-edition artworks you
won’t find anywhere else—each one bursting with Sage x Clare’s signature boho charm. Available in a range of sizes to fit every bed, our buttery-soft cotton Duvet covers are made to be mixed, matched and layered to your heart’s content.

Why Choose Cotton Duvet Covers?

Nothing beats that soft-against-your-skin, snuggle-me-now feeling of cotton. Loved for its breathability, buttery texture and all-season comfort, cotton sheets are a forever favourite in the bedroom—and for good reason. It keeps you cool in summer, cosy in winter and
comfy always, thanks to its clever ability to regulate temperature naturally. Gentle on sensitive skin and hypoallergenic by nature, cotton is a dream for allergy sufferers. Plus, it’s durable enough to keep up with daily life while staying beautifully smooth wash after wash. Wrapped in Sage x Clare’s signature prints and joyful palettes, our cotton Duvet covers are equal parts functional and stylish—a feel-good choice in every way.

Caring for Your Cotton Duvet Covers

Want that fresh-sheet feeling to last? A little love goes a long way. To keep your cotton Duvet covers looking and feeling their best, we recommend a gentle machine wash in cold water with a mild detergent—no bleach or harsh chemicals needed. Line drying in the shade is ideal to preserve colour and softness, but a tumble dry
on low heat works when the weather’s not playing nice. When not in use, store your covers in a cool, dry space. With just a touch of care, your cotton Duvet covers will stay soft, vibrant and snuggle-ready for many dreamy nights to come. For more tips head to our Care Instructions.

Take the guesswork out of making your dream bed—check out our Bedding Size Guide for all the sizing details you need. 

Is 100% cotton good for a Duvet cover? 

It sure is—100% cotton is one of the best choices you can make for a Duvet cover. Naturally breathable and temperature-regulating, it keeps you cool in the warmer months and cosy when it’s cooler, making it perfect for year-round comfort. It’s hypoallergenic, kind to sensitive skin and only gets softer with every wash. Strong yet irresistibly soft, cotton is made to go the distance—through lazy sleep-ins, Sunday snuggles and everything in between. Add
Sage x Clare’s signature joyful palettes and nostalgic prints and you’ve got a Duvet cover that’s as beautiful as it is blissful to sleep in.

What is the best thread count for a cotton Duvet cover?

When it comes to cotton Duvet covers, higher thread count doesn’t always mean higher quality—it’s all about balance. The magic number for cotton Duvet covers? Anywhere between 200 and 400, where the fabric feels beautifully soft, breathable and durable enough for daily use. Too high, and you risk a heavy, less breathable fabric; too low, and it may not wear as well over time. At Sage
x Clare, we choose thread counts that strike just the right harmony between comfort and longevity—so your bedding feels luxe, lives well and looks amazing.

Is it better to sleep on linen or cotton?

It really comes down to your personal sleep style—both cotton and linen bedding bring their own kind of joy to the bedroom. If you’re after that crisp, smooth feel with a soft-to-the-touch finish, cotton Duvet covers are just the thing for you. Breathable, hypoallergenic and oh-so-easy to care for—perfect for everyday comfort with a
polished twist. On the flip side, linen Duvet covers have a beautifully relaxed texture, a bit more weight and a naturally rumpled charm that gets softer over time. It’s ideal for those who love a laid-back, lived-in look and crave that breathable, temperature-regulating magic year-round. Can’t decide? No worries—we’re big believers in mixing, matching and making your bed your way. Blend a little linen, toss in some cotton pillowcases and layer up the comfort to create the ultimate sleep space that’s uniquely yours. Dive into our bedding
collection
and start building your best-ever bedroom setup.
