The Best Coffered Ceiling: Our Picks

Guide: Questions you should ask yourself before buying a coffered blanket

Who is a cassette blanket suitable for?

In principle, a cassette blanket is suitable for everyone who uses a blanket in everyday life. With its many advantages, the cassette blanket is one of the most popular among blankets.

The cassette quilt is characterised by the fact that its construction protects the inner lining from slipping. The filling is divided into individual closed cassette chambers, which means that the material has less freedom of movement and cannot slip. There are cassette blankets that are suitable for winter, summer and year-round use. Which cassette quilt is right for you depends on your personal requirements. You can choose between different models.

Cassette blankets help keep you warm by regulating your body temperature and absorbing sweat. While you sweat, it ensures that you stay dry.

The health aspect of the cassette blanket is also not to be sneezed at. Because of the way they are made, cassette blankets offer you a high level of thermal insulation. The even distribution of the filling in the cassettes protects your body from excessive heat loss.

What material should a cassette blanket be made of?

Cassette blankets can be made of different materials. A distinction is made between the cover and the filling of the cassette blanket.

The filling of a cassette quilt is usually made of feathers or down. The outer material, on the other hand, is usually cotton.

Cotton is characterised by the fact that it is a very durable material, which is robust and tear-resistant. It is very absorbent and has a low allergy potential. That is why its coarse fibres make it perfect to use as the cover for the filling of a cassette quilt.

The filling of a duvet, on the other hand, usually consists of feathers or down. Both materials have different properties and thus fulfil different tasks. You can find out more about these in the decision section. Which material you ultimately choose depends on your own preferences and requirements.

What are the alternatives to a cassette quilt?

Cassette quilts belong to the group of quilts. Each quilt has a different quilting. In addition to the cassette shape, there are also other quilting styles. In the following section we will give you a brief overview of the alternatives to the cassette quilt pattern.
Type Description
Pull-in quilt top and bottom fabric are joined together, heat can be easily dissipated. Suitable as a summer quilt
Checkered quilt quilting sewn in a chequered pattern, filling can wander but is sewn crosswise and in a straight line.
Balloon quilt quilt is not sewn, filling can move freely. Balloon duvet loses importance due to property
Cassette duvet Suitable all year round, Chambers divided into cassettes prevent heat from escaping

Each of the quilts has certain advantages that are not to be sneezed at. Nevertheless, the cassette quilt seems to be superior to the others in many criteria. Because of its multifunctionality, it combines the functions of the other quilts.

Decision: What types of coffered ceilings are there and which is the right one for you?

Basically, a distinction can be made between two different types:

  • Feather cassette quilt
  • Down cassette quilt

We will explain the advantages and disadvantages of each in the following paragraphs to make your decision easier.

What are the characteristics of a feather quilt and what are its advantages and disadvantages?

A quilt with an inner filling of feathers is characterised above all by the naturalness of the material. Due to their properties, feathers are particularly suitable for when you get warm quickly. Since they do not serve as a heat accumulator, your body temperature cannot rise and you sweat less. Feathers also offer a high filling quantity due to their size. If you are looking for a pillow, it is recommended that you choose a pillow filled with feathers, as this offers good support due to the high filling quantity. The following table shows the advantages and disadvantages of feather filling.

  • filling quantity
  • offers weight
  • natural material
  • low price
  • unprocessed product
  • Heavy
  • No thermal insulation
  • Material can prick

Which material is right for you depends on your personal preferences and wishes. If you like it cool and don’t want your body temperature to rise, you should go for a feather filling.

What are the characteristics of a down duvet and what are its advantages and disadvantages?

A cassette duvet with down filling is characterised by its multifunctionality. Because the material does not have a keel, the down is particularly soft and does not prick. Down consists of the lower material of geese or ducks. They are particularly fluffy and resemble a tuft. One of the properties of down is its high thermal insulation. It provides a temperature balance between body temperature and the blanket. Down can store air well. This makes it fluffy and voluminous. The material is particularly soft because there is no stalk. The following table shows the advantages and disadvantages of down filling.

  • Temperature compensation
  • Natural material
  • Lightweight
  • Suitable for allergy sufferers
  • Suitable for sweating
  • Expensive
  • Not suitable for pillows
  • Material can prick
  • Can tear

Which material is right for you depends on your personal preferences and wishes. If you like to be warm and don’t want to freeze at night, you should choose a down filling.

Buying criteria: These are the factors you can use to compare and evaluate duvets

In the following, we would like to show you which factors you can use to compare and evaluate cassette blankets. This will make it easier for you to decide whether a certain cassette blanket is suitable for you or not. In summary, these are:

  • Quilting
  • Warmth class
  • Size
  • Layers


The quilting of your coffered quilt can have different patterns. Most of the time it consists of box-shaped squares. However, it is also possible for you to have a check pattern or diamond pattern. The pattern has no influence on the filling quantity of your coffered quilt. Which pattern you choose depends on your own personal preferences. There are also blankets that are not sewn in layers. However, the filling can easily slip out of place. That is why it is advisable to use a cassette blanket

Did you know that there are no cold bridges with a cassette blanket? Because of the integrated bar in cassette blankets, the blanket has the desired height/density at every point. The filling cannot slip and heat cannot escape. Depending on the height of the filling, the blanket is insulated against the cold. A winter duvet therefore has a higher filling quantity than a summer duvet.

Warmth class

There are different warmth classes for duvets. These tell you when you can use your duvet. Depending on your requirements, you will need a different duvet. In the following table you can see all the warmth classes with their areas of application.

Warmth class Application
Warmth class 1 Very light duvet with low heat output, high bedroom temperatures from 25 degrees
Warmth class 2 Light duvet with low heat output – suitable for summer.
Warmth class 3 sleeping temperature approx. 17-21 degrees, suitable for people with a balanced feeling for warmth
Warmth class 4 cosy and warm with a high heat output, suitable from autumn to winter.
Warmth class 5 very high heat output, also suitable for sub-zero temperatures.
Warmth class 6 4 seasons blanket, consists of two blankets. Underblanket and overblanket. Suitable for winter and summer.

Which warmth class you choose depends on your ambient temperature and your own needs and preferences.


The size of your cassette duvet plays a big role in your comfort. There are cassette quilts that you can use alone or quilts that are large enough for two people to use. Which model you choose depends on what your needs are. When buying, it is important that you choose a duvet that is not too small, as this would cause a lot of heat loss.

Cassette quilts are characterised by the fact that you have the pattern of individual filled cassettes that are closed. These boxes are available in 4×6 or 3×4 grid.

The standard size for duvets is 135×200 cm for a normal body size and average build. The comfort size starts at 155×220 cm. There are also duvets that are larger or smaller.


A duvet consists of several layers. One is the inner lining and the other is the outer material, which acts as a protective cover. All materials have different functions and properties. The outer layer serves to protect your filling and is therefore very robust or tear-resistant. Coarse-fibre cotton is often used for this purpose. Alternative materials are microfibre and synthetic. Different inner layers are also used for the filling. The most common materials are feathers and down, as these offer good bulk. The individual filled boxes in the inner lining are sewn together with ribbons in the inner life so that the filling cannot slip. These create a plane and the blanket is not just bottom and top, but offers a space in between that can be between 2 cm and 15 cm wide, depending on the amount of filling.

Did you know what is called a bar in coffered blankets? The inner web of a coffered ceiling is the height separation that separates the upper and lower ceiling. The inner web is worked into the box by tapes and serves to prevent the inner material from slipping.

Facts worth knowing about cassette quilts

How do I wash a cassette quilt?

Before you wash your cassette quilt, you should first read the manufacturer’s information on the label. In the following, we explain the best way to wash your cassette duvet in the washing machine: Make sure your cassette blanket is in perfect condition and has no tears before washing it.

  1. Shake out your cassette quilt well before washing it. This will help remove excess dirt before washing.
  2. Fold your cassette quilt and place it in your washing machine. Choose a low spin cycle to avoid damaging your fabric.
  3. Attention. You should always use a special detergent for the material of your cassette blanket. Never use fabric softener when washing
  4. If your duvet is made of down or feathers, you should always put 3 tennis balls in the drum to prevent the feathers from clumping together. You can also dry a duvet made of down with 3 tennis balls in the dryer at 40 degrees.

The following video gives you a general overview of down care tips.

How do I sew a cassette quilt?

If your cassette quilt is damaged, you should first identify the area of damage. Once you have found it, you can either sew your cassette quilt yourself or have it professionally sewn. We recommend that you have the blanket professionally repaired if you do not know exactly how to sew a blanket. However, before you sew your blanket, you should collect any lost lining and put it back into the blanket. In the following video you will see instructions on how to mend a hole with an open filling without the seam being visible.

How do I dispose of a cassette blanket?

If you decide to dispose of your cassette blanket, you have several options. If your duvet is made of natural material, such as down, you can have your duvet recycled. There are organisations and contact points that will accept your duvet. You can also hand in your duvet at an old clothes donation centre. Another option would be to separate the cover and the filling to ensure better recycling. However, this is a big hassle and not necessary if your blanket is fully recyclable.

If your cassette blanket is contaminated with chemicals, you should dispose of it in hazardous waste to prevent damage.

Otherwise, you can dispose of your cassette blanket in your household waste.
