WHY DELARA WORKS BETTER
Organic cotton's hollow fibers promote continuous airflow, releasing excess warmth as body temperature rises for a cooler, more comfortable sleep.
GOTS is the world's most rigorous organic textile certification, ensuring cotton is responsibly grown and processed without harmful chemicals.
Free from synthetic fillers, harsh chemicals, and pesticide residues, with GOTS-certified materials independently tested for safety, comfort, and purity.
Organic cotton uses less water and no synthetic pesticides, while GOTS certification ensures responsible materials and ethical production throughout.

Certified, Not Just Labeled
Organic is one of the most misused words in bedding. Here's what makes ours verifiably different.
GOTS is the world's leading organic textile certification, covering everything from cotton farming to final production. Unlike brands that certify only the shell, Delara's certification covers both the fill and shell for complete peace of mind.
Yes. The breathable structure of GOTS-certified organic cotton allows heat and moisture to escape naturally, helping your body stay comfortable without overheating-especially for warm sleepers and humid climates.
No. It has a soft, gently grounding weight that feels comforting without pressure. It settles naturally over the body rather than feeling bulky or restrictive.
Yes. This cotton duvet insert is designed for everyday, all-season use. It’s breathable enough for warmer months and pairs easily with layers or a cover for cooler nights.
Cotton offers a clean, breathable, and lightweight feel. Compared to wool, it’s less insulating and better suited for warm or neutral sleepers. Compared to microfiber, cotton is more breathable, natural, and free from synthetic heat-trapping fibers.
Yes. Made with GOTS-certified organic cotton, it’s produced without harmful chemicals or synthetic treatments, making it a gentle choice for sensitive skin and everyday use.
Yes- its all-cotton construction makes it easy to care for; machine wash on gentle and tumble dry low.

"Great loft, generous size, perfect for all year round and comfortable:"
"Breathable, best quality and temperature control I’ve found!"
"Beautifully made with excellent quality. LOVE the hard-to-find 8 tabs for securing my duvet cover. Highly recommend."
"We've used our organic cotton air duvet now for a little over a month. we like it well enough - does seem like it keeps us cooler at night. we've taken it to the dry cleaners and have not noticed any difference in the fill. I like that it's bigger than our last duvet because my husband is a cover hog."
"Love this duvet insert. So light and comfortable and feels really clean. Very happy with it."
"Perfect! I was really worried it would be too warm or not warm enough. I read reviews on this brand and several others. This seemed to be my best option because I can switch them out or use them together. It is still getting into the high 80s here and the all season layer is what we are currently using. It will probably be enough for the winter months, we rarely get below freezing. I may use the light layer during the summer months. I am usually a very hot sleeper and wake up drenched to the point of having to shower but so far I have had no problems with getting too hot. Will probably be purchasing for our grown children as well. This is our first wool duvet, really glad I went with this one!"
"We've only been using the wool 3 in 1 duvet insert for a week or so, and I'm already so glad I purchased it. We are using the all season insert as it's fall now, and I love it. We don't sweat like we did prior to using this wool insert. We still get a tad warm sometimes but nowhere near as bad as before we started using this wool duvet insert. The cotton material of the wool duvet insert, the cotton of the duvet cover, along with the cotton of the flat sheet seems hold it all together and the bed doesn't seem to get as crumpled and messy as it did with mixed fabrics (cotton & polyester). I am looking forward to trying the summer insert in my duvet next year. I'm donating my polyester insert. If you're on the fence, make the leap and get one."
"Love this. Researched many different brands, didn’t want to pay $500 and also didn’t want cheap plastic fill. This was the best option, no chemicals, organic cotton, works perfect inside my new linen duvet. I love warmth level options so I’m comfortable all year round"
"I have both organic cotton king size comforters and the Percale sheets. They are great. Wish the king size comforter was a little wider but it still fits well."
"I got the 3 in 1 wool comforter, so can speak to both the quality of the spring/summer weight and the all season. This is a really high quality product and I love that it is wool fill. Wool is sustainable, natural, non-allergenic for many, and temperature regulating. I don't overheat at all (which is a problem I have had with down and poly fill comforters) but am perfectly warm. The comforters are not as "poofy" as normal down or poly fill comforters but still very substantial, especially with both snapped together, and have a really comforting weight to them that really helps me sleep. Wool does have a "natural" smell especially when fresh but I found it in this product to be very mild and comforting, and it faded quickly with use. It is a sign that the wool is real and high quality anyway. Customer service was spectacular, there was an unexpected issue with my order and the team went above and beyond to make it right. I don't leave a lot of reviews but I am so happy with my Delara comforters!"
