Pudebetrækket er lige så blødt som dynebetrækket, så sengen føles mere behagelig.

Danish very often makes compound nouns, just like English does in words such as bedroom, toothbrush, or pillowcase.

• pude = pillow
• betræk = cover, case

So:

• pudebetræk = pillow cover / pillowcase
• dynebetræk = duvet cover

Then -et is added because the nouns are in the definite form:

• pudebetræk = a pillowcase

• pudebetrækket = the pillowcase

• dynebetræk = a duvet cover
• dynebetrækket = the duvet cover

So the long words are built in a very regular way.

In Danish, the definite article is often added to the end of the noun instead of being a separate word before it.

For neuter singular nouns like betræk, the definite ending is -et:

• et betræk = a cover
• betrækket = the cover

This is why you get:

• pudebetrækket = the pillowcase
• dynebetrækket = the duvet cover

This is one of the biggest differences from English.

Because blødt agrees with the noun it describes.

The noun behind pudebetrækket is betræk, which is a neuter noun:

• et betræk

When an adjective describes a singular neuter noun after er, it usually takes -t:

• Betrækket er blødt = The cover is soft

Compare:

• en pude er blød = a pillow is soft
• et betræk er blødt = a cover is soft

So blødt is there because the thing being described is grammatically neuter.

Lige så ... som means just as ... as or simply as ... as.

Structure:

• lige så + adjective/adverb + som

Examples:

• lige så blødt som = as soft as
• lige så stort som = as big as
• lige så hurtigt som = as quickly as

In your sentence:

• Pudebetrækket er lige så blødt som dynebetrækket
• The pillowcase is just as soft as the duvet cover

The word lige adds the sense of exactly / just.

Yes, sometimes you can, but lige så ... som is the normal full pattern for as ... as.

• lige så blødt som = just as soft as / as soft as

If you leave out lige, the sentence may still be understood in some contexts, but lige så ... som is the standard form learners should aim for.

So this sentence is using the most natural textbook pattern.

There are actually two different uses of så in this sentence.

1. In lige så blødt som, så is part of the comparison pattern as ... as.

2. After the comma, så means so / therefore:

• ..., så sengen føles mere behagelig
• ..., so the bed feels more comfortable

So the same word appears twice, but it has two different functions.

It actually does match English pretty closely here:

• sengen = the bed
• føles = feels

So:

• sengen føles mere behagelig
• the bed feels more comfortable

The word order is normal Danish main-clause word order: subject + verb.

Because så here means so/therefore and connects two main clauses, the second clause keeps normal main-clause order:

• ..., så sengen føles mere behagelig

If this were a subordinate clause introduced by words like fordi or at, the word order would be different.

Føles comes from at føle.

In this sentence, føles means feels in the sense of seems to feel / has a certain feel.

The -s form is very common in Danish and can have several uses. Here it works like English feel in sentences such as:

• Stoffet føles blødt = The fabric feels soft
• Sengen føles mere behagelig = The bed feels more comfortable

So you do not need a reflexive pronoun here. Danish simply uses the -s form naturally in this kind of sentence.

Because behagelig describes sengen, and seng is a common gender noun:

• en seng = a bed

With a common gender singular noun, the adjective stays in its basic form:

• sengen føles behagelig = the bed feels comfortable
• sengen føles mere behagelig = the bed feels more comfortable

Compare with a neuter noun:

• et værelse føles behageligt = a room feels comfortable

So:

• en seng → behagelig
• et ... noun → behageligt

Danish often forms the comparative with mere + adjective, especially with longer adjectives.

• behagelig = comfortable
• mere behagelig = more comfortable

For many short adjectives, Danish often uses an ending instead:

• blød → blødere = softer
• stor → større = bigger

But with longer adjectives like behagelig, mere behagelig is the natural choice.

The base form is seng:

• en seng = a bed
• sengen = the bed

This is a common gender noun, so the definite ending is -en.

Compare:

• en seng → sengen
• et betræk → betrækket

So the sentence contains both common-gender and neuter definite forms.

Danish punctuation usually places a comma between clauses more often than English learners may expect.

Here the comma separates two clauses:

• Pudebetrækket er lige så blødt som dynebetrækket
• så sengen føles mere behagelig

So the comma helps show the boundary between the first statement and the result clause.

Even if comma rules vary a bit by style and system, a comma here is very normal and natural.

You would remove the definite endings:

• et pudebetræk = a pillowcase
• et dynebetræk = a duvet cover
• en seng = a bed

Then a sentence could look like:

• Et pudebetræk er lige så blødt som et dynebetræk.
• A pillowcase is as soft as a duvet cover.

So the original sentence is talking about specific items:

• pudebetrækket = the pillowcase
• dynebetrækket = the duvet cover
• sengen = the bed

Not exactly. Dyne usually means a duvet or quilt-type bed covering, the thick bedding you put inside a duvet cover.

So:

• dyne = duvet
• dynebetræk = duvet cover

A general blanket is more often tæppe or, in some contexts, et tæppe depending on what kind of blanket is meant.

So dynebetræk is specifically a cover for a duvet, not just any blanket.

Yes. It is a very useful pattern:

• X er lige så + adjective + som Y, så Z + verb + comparative adjective

Examples:

• Sofaen er lige så blød som sengen, så rummet føles mere hyggeligt.

• The sofa is as soft as the bed, so the room feels cozier.

• Skjorten er lige så ren som bukserne, så tøjet ser mere pænt ud.
• The shirt is as clean as the trousers, so the clothes look nicer.

So this sentence is good practice for:

• compound nouns
• definite forms
• adjective agreement
• comparisons with lige så ... som
• result clauses with så
