What's the best duvet for hot sleepers?

For hot sleepers, we recommend lightweight and breathable duvets with 150GSM loft, and excellent moisture absorption.

What does GSM mean on a duvet inner?

For a duvet inner, GSM stands for Grams per Square Metre. It measures the weight and density of the filling – basically, how much “stuff” is inside.

Here’s a quick breakdown for choosing one:

• 150 – 250 GSM: Light, breathable and best for summer or warm sleepers.
• 300–450 GSM: Great for year-round comfort in most New Zealand homes.
• 500+ GSM: Designed for maximum warmth and insulation to suit colder climates or homes with poor insulation. Has that “heavy” feel people find cosy during cold nights.

What is the best duvet inner for year-round comfort?

The ideal insert balances weight and breathability. Choose NZ wool or feather and down for natural temperature regulation, or a high-quality microfibre-filled product as a down alternative. All Season duvets feature two separate inners – a lightweight one (for summer) and a medium-weight one (for autumn/spring).

You can clip, snap, button or tie them together to create a heavy, high-GSM duvet for maximum winter warmth. It’s the most versatile option for New Zealand's changing seasons.

Is the duvet inner the same as a doona or a quilt?

Yes, they are all the same thing and are often used interchangeably. Essentially referring to a bed covering filled with down, feathers, or synthetic fibres. The terminology depends on who you are talking to.

• Duvet Inner is the standard term here in New Zealand.
• Doona is what Australians call it.
• Quilt is the term Americans use. Although some people in NZ use “quilt” to mean a decorative bedspread used as a top layer for additional warmth, no cover is required.

What size duvet inner should I buy for my bed?

The general rule is to match the duvet to your mattress.

For a more hotel-style, luxurious look, we recommend going up a size (e.g., a King inner for a Queen bed). This provides better overhang, especially for deep mattresses or with a plush topper. Also, perfect if you have a partner who likes to steal the covers. Just make sure to buy a cover that matches the insert's size.

How often should I replace my duvet inner?

You should generally replace your duvet inner (or insert) every 5 to 10 years. While they last longer than pillows, their ability to keep you warm and fluffy declines over time.

How to tell when it’s time for a new one

• Feels flat or thin, and no longer keeps you warm
• The filling has clumped, creating cold spots.
• Persistent yellowing or smell, even after a wash.
• If the feathers and down filling are poking out.
• Your allergy symptoms have worsened, suggesting a buildup of dust mites and other allergens.

What are the best duvet cover materials for people with allergies?

If you or someone in your household has allergies or sensitive skin, consider a hypoallergenic duvet cover. Look for materials such as organic cotton, bamboo, Tencel and wool.
