The Best Mattress Wedge: Our Choices


  • A mattress wedge is used for the visitor's gap that occurs in a double bed with two mattresses. This creates a uniform surface.
  • With a mattress wedge, you should definitely pay attention to the slip resistance and the allergy friendliness. Whether it is washable is also important.
  • The width of the gap between the mattresses is important. The length of some models can be easily adjusted by cutting them to size.

Guide: Questions you should ask yourself before buying a mattress wedge

For whom is a mattress wedge useful?

A mattress wedge is intended for the so-called visitor's gap, i.e. the gap between two mattresses in a double bed.

With the help of the mattress wedge, also called a love bridge, this gap is closed by placing it between the two mattresses and fastening it.

This creates a beautiful and larger bed to snuggle up in.

In addition, everyone has different preferences and requirements when it comes to a mattress. For this reason, separate mattresses are very popular. However, so that the feeling of closeness is not lost, mattress wedges are used.

So it only makes sense to buy a mattress wedge if you and your partner want to maintain the closeness to each other, or if the gap bothers you during sleep.

What do I have to consider with a mattress wedge?

The most important thing to consider when buying a mattress wedge is the dimensions, as there are various mattress sizes.

If the desired size is not available, which is not likely, some mattress wedges have the option of being cut to size.

Depending on the material of the mattress, the right material can be chosen for the mattress wedge, if possible.

Since we move during sleep, slip resistance is of great importance.

Furthermore, for allergy sufferers, it is important to know whether the mattress wedge is allergy-friendly or not.

It is also important to know whether it is washable, and if so, how it should be washed.

How much does a mattress wedge cost?

Mattress wedges are relatively inexpensive. However, the price depends on the material and the size.

The price range for mattress wedges made of synthetic fibre, terry cloth and cotton is about 14 - 60 €.

What the prices are for the respective material can be seen in the following table.

Type Price range
Mattress wedge made of synthetic fibre approx. 21 - 22 €
Mattress wedge made of terry cloth approx. 15 - 34 €
Mattress wedge made of cotton approx. 14 - 60 €

As shown in the table, the cotton mattress wedge is the cheapest to buy at about 14 €, but it can also be available for about 60 €.

With a maximum amount of about 34 €, the mattress wedge made of terry cloth is the average, the mattress wedge made of synthetic fibre is in the low price segment with about 22 €.

How can I make a mattress wedge myself?

Making a mattress wedge yourself is very easy and has only a few steps.

First of all, you need to know the important measurements. The length of your mattress, the width of the visitor's groove and its depth, i.e. the depth of the mattress, are important.

After you have this information, you need to get your filling material, such as foam. You can find materials at the DIY store.

We recommend that you buy the filling material in its entirety so that you can cut it yourself later according to your needs.

To protect the finished mattress wedge, it is recommended to use a cover.

Now you can place your own mattress wedge in the gap.

What is the alternative to a mattress wedge?

If you do not choose a mattress wedge, you will find alternatives in the following table.

Alternative Description
Mattress topper Using a mattress topper results in a uniform surface. Mattress toppers are available in different sizes. Among other things, they make the mattress softer. However, you should note that your and your partner's requirements for a mattress cannot be met because individualisation is not possible.
Extra cover Some manufacturers offer an extra cover to prevent a visitor's crack from forming altogether. Due to the force exerted on both mattresses, the mattresses lie firmly against each other and no visitor's crack is formed that can be felt.

If you are not sure whether a mattress wedge is right for you, we recommend that you compare it with the alternatives and make the right decision for you.

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

Once you have decided on a mattress wedge, it depends on which material it is made of.

In this section, we will introduce you to three different materials and their advantages and disadvantages.

You have the choice between one:

  • Mattress wedge made of synthetic fibre
  • Terrycloth mattress wedge
  • Cotton mattress wedge

We would like to help you find the right material for you. Take the time to weigh up the advantages and disadvantages of the materials.

What are the advantages and disadvantages of a mattress wedge made of synthetic fibre?

When you look at mattress wedges online, you will come across the term foam. Foam is made from synthetic fibres.

Synthetic fibres are made from petroleum, which is chemical. That is why they are also called man-made fibres.

  • Durable
  • Immune to infestation by insects
  • Tear-resistant
  • Environmentally hazardous

Synthetic fibres are viscose, polyester, polyacrylic and polyamide. Each synthetic fibre is used for different things, such as viscose for upholstery covers.

What are the characteristics of a terry towelling mattress wedge and what are its advantages and disadvantages?

The word terrycloth is derived from the French of terry and means to rub. Due to its high absorbency, terry cloth is very popular in the production of towels.

Terrycloth is a textile fabric and is usually made of cotton, which is combined with fancy yarn.

  • Easy care
  • Resistant
  • Pleasant on the skin
  • None

During the production of terry cloth, the yarn is twisted into loops and loops. Terrycloth has a somewhat rough surface because of these loops and loops.

What are the characteristics of a cotton mattress wedge and what are its advantages and disadvantages?

Cotton is a natural plant fibre and consists of about 91% cellulose. It is obtained from the fruit capsules of the plant. Cotton is grown exclusively on plantations. In the past, the plant was picked by hand, but today this is done with the help of machines called cotton harvesters.

  • Skin-friendly
  • Allergy-friendly
  • Durable
  • Easy-care
  • Cotton wears out
  • Fluctuating quality and strength of fibres

The largest cotton producers are China, India, the USA and Pakistan, among others.

There are three types of cotton: Mako cotton, Sea Island cotton and organic cotton. Malo cotton only comes from Egypt, Sea-Island cotton from America. Certified organic cotton has not been exposed to chemical pesticides and fertilisers.

Buying criteria: You can compare and evaluate mattress wedges based on these factors


This purchase criterion is very important because not every mattress is the same size.

Depending on the size of the gap, the mattress wedge must be adapted to it.

Without the right size, the mattress wedge cannot perform its function. This means that the width of the love bridge must be adapted to the width of the gap.

In addition, it must be as long as your mattress.


Slip resistance is also very important for this product.

Since we move a lot during our sleep, a non-slip mattress wedge is very important. It must not come out of the gap easily.

So pay attention to the product information when searching for the perfect love bridge.

The measurements are also important here, as the wrong ones will cause the gap filler to slip.

Cutting to size possible

As already mentioned, the measurements of mattress wedges play a significant role. Some manufacturers offer mattress wedges that can also be cut to size.

If, for example, the width is right but the length is not, you can easily adapt them to your mattress.


According to our research, every material we have presented here can be washed. The majority can only be washed at 30º C and must be 100% dry before the love bridge can be used again.


You must always be careful when washing: if you wash something incorrectly just once, it can break immediately or the longevity is lost.

When it comes to a mattress, allergy friendliness is very important. This also applies to mattress wedges.

Here, too, you should pay attention to manufacturers' instructions. A certification should be available.


Cotton is the most commonly used material in the textile industry. For this reason, you should be aware that pesticides are often used on plantations. If you want to be on the safe side, we recommend organic cotton.

As a rule, synthetic fibres are allergy-friendly. Cotton is a little different. Cotton is often treated with pesticides or bactericides. This can cause problems for allergy sufferers.

This also includes terry cloth, as it is also partly made of cotton.

Facts worth knowing about the topic of mattress wedges

How can I wash the mattress wedge?

The manufacturer will tell you whether mattress wedges can be washed at all. The manufacturer will also tell you whether you should wash them normally in the washing machine or by hand. You should definitely pay attention to this.


It is easier to always wash everything in the washing machine, but this is not suitable for all materials and products. Therefore, you should always pay attention to the manufacturer's instructions.

As already mentioned, synthetic fibres, cotton and terrycloth can generally be washed at about 30º C.

Do I need a cover for the mattress wedge?

A cover for the mattress wedge is not really necessary. However, if you want to protect it from dirt and dust, it is advisable to buy a crevice filler with a cover.

If you can't find a mattress wedge with a cover, you can easily make your own.

Can I also use a mattress wedge for my head or legs?

There is no such thing as a mattress wedge for the head and for the legs. This product is called a wedge pillow.

Wedge pillows for the head help with reflux and back and shoulder problems. It is also supposed to counteract snoring. This happens by slightly elevating the body through the pillow.

The wedge pillow for the legs is also often called a vein pillow.

Wedge cushions can also be used as a seat cushion. You can find them in various sizes.
