Kursi belakang lebih nyaman daripada kursi depan.

In Indonesian, a noun usually comes before the word that describes or specifies it.

So:

• kursi belakang = the back seat / rear seat
• kursi depan = the front seat

This is similar to how Indonesian often puts the main thing first, then adds more information after it.

Compare:

• rumah besar = big house
• mobil baru = new car
• kursi belakang = back seat

So belakang and depan are coming after kursi to specify which seat.

Here:

• belakang = back / rear
• depan = front

In this sentence, they act like location-based descriptors for kursi:

• kursi belakang = rear seat / back seat
• kursi depan = front seat

These words can also be used in other ways:

• di belakang rumah = behind the house
• di depan toko = in front of the shop

So they are flexible words that can refer to position or location depending on context.

Lebih ... daripada is the normal pattern for comparisons in Indonesian.

Structure:

• lebih + adjective + daripada + noun

In your sentence:

• lebih nyaman daripada = more comfortable than

So:

• Kursi belakang lebih nyaman daripada kursi depan.
  = The back seat is more comfortable than the front seat.

More examples:

• Dia lebih tinggi daripada saya. = He/She is taller than me.
• Mobil ini lebih mahal daripada mobil itu. = This car is more expensive than that car.

A very useful pattern to remember is:

• A lebih X daripada B = A is more X than B

Yes, in comparisons like this, daripada usually means than.

For example:

• lebih besar daripada = bigger than
• lebih cepat daripada = faster than

However, daripada can also appear in some other expressions, so it is not always a perfect one-word match in every situation. But in this sentence, thinking of it as than is exactly right.

Indonesian often does not use a verb like is / are in simple descriptive sentences.

So instead of saying something literally like:

• The back seat is more comfortable than the front seat

Indonesian simply says:

• Kursi belakang lebih nyaman daripada kursi depan

This is very normal. Indonesian often leaves out the equivalent of to be when describing something.

Examples:

• Rumah itu besar. = That house is big.
• Dia sakit. = He/She is sick.
• Kursi belakang lebih nyaman... = The back seat is more comfortable...

Yes, kursi is repeated for clarity, but in some contexts it can be omitted if the meaning is obvious.

Full version:

• Kursi belakang lebih nyaman daripada kursi depan.

A shorter version you may hear:

• Kursi belakang lebih nyaman daripada depan.

The full version sounds clearer and is especially good for learners. Repeating the noun is very common and completely natural.

So:

• daripada kursi depan = clearer, more explicit
• daripada depan = shorter, but depends more on context

Yes, nyaman is an adjective.

It usually means:

• comfortable
• pleasant
• cozy

In this sentence:

• lebih nyaman = more comfortable

You can use nyaman for many situations:

• Kursi ini nyaman. = This chair is comfortable.
• Rumahnya nyaman. = His/Her house is comfortable/cozy.
• Saya merasa nyaman di sini. = I feel comfortable here.

So nyaman is a very useful everyday word.

Usually yes, especially in context like a car.

• kursi belakang = back seat / rear seat
• kursi depan = front seat

If the context is a vehicle, that is the most natural interpretation.

However, outside a vehicle context, kursi belakang could also literally mean the chair at the back. Context tells you which meaning is intended.

So in many everyday situations, especially talking about cars, kursi belakang is best understood as the back seat.

Indonesian does not normally use articles like English a/an/the.

So:

• kursi belakang can mean the back seat or a back seat
• kursi depan can mean the front seat or a front seat

The exact meaning depends on context.

In this sentence, English naturally uses the:

• The back seat is more comfortable than the front seat.

But Indonesian does not need separate words for that.

In everyday speech, many speakers do say lebih nyaman dari, and you will definitely hear it.

However, for standard grammar and for learners, lebih ... daripada is usually the safer and more recommended form for comparisons.

So:

• lebih nyaman daripada kursi depan = standard, clear
• lebih nyaman dari kursi depan = common in speech, but less formal/less preferred in careful grammar

If you are learning, it is best to master lebih ... daripada first.

The original sentence is already natural. In speech, people might also say:

• Kursi belakang lebih nyaman daripada kursi depan.
• Kursi belakang lebih nyaman daripada depan.
• Di belakang lebih nyaman daripada di depan.

The last one shifts the focus from the seat to being in the back versus being in the front:

• Di belakang lebih nyaman daripada di depan.
  = It’s more comfortable in the back than in the front.

So the best version depends on exactly what you want to emphasize.
