Duvet Insert Buying Guide

Choosing the right duvet insert involves more than just buying the right size. To get the look and comfort your want and need from your duvet, it's important to understand all of the different options that are available. Here are a few important features to keep in mind as you shop Pottery Barn's selection of inserts.

Fill Type

The first thing you'll want to consider when buying a duvet insert is the fill type. A duvet filled with duck or goose down will provide better insulation than down alternative, but it is not an ideal choice for allergy sufferers. Down alternative, on the other hand, is hypoallergenic, but not as warm as down.

Fill Power

Equally as important as a duvet insert's fill type is its "fill power." This refers to the amount of actual space the down takes up within the comforter. The more space the down takes up, the warmer the duvet. A good quality duvet insert will have a fill power of at least 600 (or equivalent rating if down alternative).


The shell of a duvet can be made from a variety of materials, including cotton, silk and silk blends. Cotton is the most durable and easy-to-maintain choice, while silk and silk blends have a luxurious finish that's elegant enough to use uncovered - although they may require specialized care.


A duvet's construction type will determine how well the filling stays in place and resists flattening. Duvets feature two basic types of construction: box stitch and baffle box. Box-stitch construction, also referred to as sewn-through construction, consists of two pieces of fabric filled and sewn into squares, creating a quilted pattern that prevents fill from shifting. Baffle-box duvets have sewn-in chambers with side walls that not only keep the fill from shifting but also ensure more even distribution of warmth.

Tog Rating

A tog rating is a measure of a duvet's thermal insulation based on a scale of 1 to 15, where 1.5 is cool and lightweight and 15 extra toasty. If you live in a climate with cold winters, you'll want a duvet insert with a tog rating of at least 13. If you live in a warmer climate, a duvet with a tog rating between four and nine will keep you cozy at night without causing you to overheat.


When buying a duvet cover, consider if you'll need a cover for it or if you plan to use it without. Add style with a duvet cover and some throw pillows. Some duvets come with a cover, saving you the time and hassle of shopping for a separate piece.

When it comes to duvets, not all inserts are created equal. Keeping the above points in mind as you shop will help you choose a cover that's perfectly tailored to your bed.
