Después de deshacer la cama, quiero cambiar la funda del edredón.

After después de, Spanish normally uses an infinitive if the subject is the same as in the main clause.

So:

• Después de deshacer la cama, quiero cambiar la funda del edredón. = After unmaking the bed, I want to change the duvet cover.

You do not use a conjugated verb like deshago after de.

If the subject changes, Spanish usually uses después de que + conjugated verb:

• Después de que mi hermano deshaga la cama, cambiaré la funda. = After my brother unmakes the bed, I’ll change the cover.

Deshacer la cama literally means to undo the bed, but in natural English it usually means:

• to unmake the bed
• to strip the bed (in some contexts)
• to mess up the bed or to take the bedding off, depending on context

In this sentence, because the speaker then says they want to change the duvet cover, it strongly suggests taking the bed apart / removing the bedding rather than just leaving it messy.

It is the opposite of hacer la cama = to make the bed.

Spanish often uses the definite article where English might use a possessive or no article at all.

So Spanish says:

• deshacer la cama
• literally: unmake the bed

Even if it means my bed from context, Spanish commonly prefers la cama instead of mi cama unless the speaker specifically wants to emphasize whose bed it is.

Compare:

• Voy a hacer la cama. = I’m going to make the bed / my bed.
• Voy a hacer mi cama, no la tuya. = I’m going to make my bed, not yours.

Quiero cambiar literally means I want to change.

It expresses intention or desire.

Possible alternatives:

• Cambio la funda del edredón.
  = I’m changing the duvet cover / I change the duvet cover.
  This sounds more direct or matter-of-fact.

• Voy a cambiar la funda del edredón.
  = I’m going to change the duvet cover.
  This focuses more on a near-future plan.

• Quiero cambiar la funda del edredón.
  = I want to change the duvet cover.
  This highlights the speaker’s wish or intention.

So the original sentence is perfectly natural if the speaker is expressing what they intend or want to do next.

Spanish often omits subject pronouns because the verb ending already shows the subject.

• quiero = I want

So yo quiero is possible, but yo is often unnecessary.

You would include yo for emphasis, contrast, or clarity:

• Yo quiero cambiar la funda, pero tú no. = I want to change the cover, but you don’t.

In neutral speech, quiero cambiar... is more natural than yo quiero cambiar...

Funda means a cover that goes over something.

In household vocabulary, it can refer to things like:

• funda de almohada = pillowcase
• funda del edredón = duvet cover
• funda del sofá = sofa cover
• funda del móvil = phone case

So here, la funda del edredón is the removable fabric cover that goes around the duvet or quilt.

Both structures can exist in Spanish, but they are not always used in the same way.

• la funda del edredón = the cover of the duvet / the duvet’s cover
• una funda de edredón = a duvet cover as a type of item

So:

• Quiero cambiar la funda del edredón.
  means you are talking about a specific duvet and its cover.

• Necesito comprar una funda de edredón.
  means you need to buy a duvet cover in general.

This is similar to the difference between the cover of the duvet and a duvet cover.

In Spain, edredón generally means a duvet, quilt, or comforter, depending on context.

In everyday Spain Spanish, many people also use nórdico to refer to the duvet, especially the kind used with a removable cover.

So in Spain you may hear:

• edredón
• nórdico

And for the cover:

• funda del edredón
• funda nórdica

Both are common, though funda nórdica is especially frequent in Spain when talking about the removable duvet cover sold in shops.

Yes. That is grammatically correct.

• Después de deshacer la cama...
• Después de haber deshecho la cama...

Both mean after unmaking the bed.

The difference is that después de haber + past participle makes the completed action a bit more explicit. It can sound slightly more formal or more precise.

In everyday conversation, después de deshacer la cama is usually the simpler and more natural option.

Because deshacer is an irregular verb, built from hacer.

Its forms follow the same irregular pattern as hacer:

• hacer → hecho
• deshacer → deshecho

Some useful forms:

• deshacer = to undo / unmake
• deshago = I undo
• deshice = I undid
• deshecho = undone / unmade

So if you use the perfect construction:

• He deshecho la cama. = I have unmade the bed.

The original word order is natural, but Spanish allows some flexibility.

Standard version:

• Después de deshacer la cama, quiero cambiar la funda del edredón.

You could also say:

• Quiero cambiar la funda del edredón después de deshacer la cama.

This puts the focus first on what you want to do.

Both are correct. The original sentence sounds very natural because it sets up the sequence clearly:

1. unmake the bed
2. change the duvet cover

Usually cambiar la funda means change the cover, which normally implies replace the current one with another one, often a clean one.

By itself, it does not usually mean only take it off.

If you wanted to focus specifically on removing it, you might say:

• quitar la funda = take the cover off
• sacar la funda = remove the cover

So in the original sentence, the most natural interpretation is:

• first, unmake the bed
• then, put on a different / clean duvet cover

The original sentence is already natural. But in Spain, many speakers might use nórdico instead of edredón in this context.

For example:

• Después de deshacer la cama, quiero cambiar la funda nórdica.

That is very common in Spain and often sounds more idiomatic when talking about modern bedding.

Still, funda del edredón is correct and understandable. It may just sound a bit more descriptive than the shorter everyday term funda nórdica.
