Frequently asked questions
What does GSM mean for linen duvets?
GSM (grams per square meter) indicates the fabric's weight. Lighter linens (under 150 GSM) are airy and best for summer, while medium (150-180 GSM) are versatile year-round, and heavy (over 180 GSM) provide a substantial, cozy feel. Our picks range from 140 to 200 GSM.
How do I wash linen duvet covers?
Machine wash on gentle cycle in cold water, and tumble dry on low or line dry. Avoid bleach and high heat to maintain fiber integrity. Pre-washed linens shrink less, but all linen may shrink slightly on first wash. Wash before first use.
Is linen better than cotton for a duvet?
Linen is more breathable and moisture-wicking than cotton, making it ideal for temperature regulation. It also gets softer over time and has a natural, textured look. However, linen wrinkles more and is often pricier than cotton percale.
What certifications should I look for in a linen duvet?
OEKO-TEX Standard 100 ensures no harmful substances, while GOTS (Global Organic Textile Standard) certifies organic fibers and ethical production. Both are common in quality linen duvets. Our picks include OEKO-TEX and GOTS certifications.
Can I use a linen duvet cover with a synthetic insert?
Yes, linen duvet covers work with any insert, but corner ties help keep it in place. For best breathability, pair with a down or wool insert. Check the cover’s size (twin, full, queen, king) to match your insert dimensions.
The verdict
The Linoto Linen Duvet Cover is our top overall pick for its premium weight and OEKO-TEX certification, while the Brooklinen Linen Core offers unbeatable value. For hot sleepers, the Cultiver Linen with its open weave is the best cooling option, and the Piglet in Bed is ideal for side sleepers seeking stability.
