How to choose between a duvet and a blanket

Short answer: A duvet insulates with air in the filling and can hold an even temperature. A blanket has less air and ends up either too cold or too heavy.

The air insulates

The duvet filling holds still air. It is the air and not the filling that warms. A blanket has less of it. See bamboo bedding.

Weight is not warmth

A heavy blanket feels warm, but does not necessarily insulate better. The weight itself can feel pleasant, but that is something else.

For warm sleepers

A light duvet or a thin blanket combined with a sheet that can release moisture is often the right choice. See home and homewear in bamboo.

One duvet each

If two people sleep at different temperatures, two duvets solve more than anything else. See bamboo nightwear for women.

The cover matters too

A dense cover limits the duvet ability to release moisture. See washing and care.

Frequently asked questions

Is a duvet warmer than a blanket?

Usually yes, because the filling holds still air that insulates.

Not necessarily. Weight feels pleasant, but does not insulate in itself.

What helps when two people sleep at different temperatures?

Two duvets. That solves more than any other single move.
