The closure on a duvet cover

Short answer: Buttons, a zip or nothing. Buttons last longest, a zip is fastest, and an open end is cheapest but lets the duvet slide out.

Buttons

Five to seven buttons across the end. They can be replaced if one comes off, and there is nothing that can break. The drawback is that closing takes longer.

Zip

Fast to close and completely closed. The drawback is that a zip in a cover is washed hundreds of times and can jam or come off its track. See bamboo bedding.

No closure

A simple opening with nothing. It works if the duvet fills the cover completely, but it works its way out over time. See bamboo sheets and bamboo pillowcases.

Frequently asked questions

Are corner ties important

They keep the duvet in place inside the cover and are worth having.
