How Long Does It Take for a Casper Mattress to Expand?

You’ve received your Casper mattress and are eager to enjoy a peaceful night’s sleep. But one question keeps popping up: “How long does it take for a Casper mattress to expand ?” Let’s make it easy to understand.

How Long Does It Take for a Casper Mattress to Expand

Mattress Type

Casper offers various mattress types, each with a different expansion time. Some mattresses have more layers, meaning they might need more time to puff up. If you’ve chosen a more complex mattress, be patient; it’s working on becoming your dream bed.

Room Temperature

It matters what temperature your room is today. The foam expands more when it’s cold, so your mattress may take longer to stretch out when it’s hard. 

So, a sweltering room isn’t ideal either. As long as the room isn’t too hot or too cold, your mattress will grow as planned.


Mattress density affects expansion time. Denser foam takes a bit longer to expand. If your mattress feels soft and thick, don’t worry how long it takes to get to you. It’s making sure you’re super comfortable.


Imagine stacking pancakes; the more you stack, the longer they cook, right? Well, thicker mattresses have more layers to puff up, so they need extra time. If you’ve chosen a thicker mattress, give it the time it needs.


Humidity, or moisture in the air, can influence expansion. In humid areas, your mattress might take longer to expand due to the humidity affecting the foam. In drier climates, it may grow faster. Think of it like how a sponge absorbs water – the more moisture in the air, the slower the expansion.

On average, a Casper mattress can take 24 to 72 hours to reach its full size. But remember that it’s already expanded to about 90% even after a few hours. So, if it doesn’t look puffed up immediately, don’t worry; it’s well on its way.

How Long Does It Take for a Casper Mattress to Inflate?

Your new mattress arrived, and now you want to make your bed as comfortable as possible. But one question looms: “How long does it take for a Casper mattress to inflate fully?” Let’s get straight to the facts.

How long does Casper mattress take to inflate

Memory Foam

Casper offers memory foam mattresses that typically take some time to inflate. A memory foam Casper mattress may take 24 to 72 hours to grow. However, you’ll notice that it expands up to about 90% of its full size in 4 to 6 hours. It won’t be at its highest point immediately, but it will be comfortable quickly.


If you’ve opted for a Casper spring mattress, you’re in for a different experience. Spring mattresses tend to inflate faster than memory foam ones. A Casper spring mattress can reach its total inflation within 12 to 48 hours. It’s a quicker process than memory foam, thanks to the nature of spring coils.


Latex mattresses, like memory foam, may need some patience. A Casper latex mattress usually inflates within 24 to 72 hours. It expands to its intended size and comfort level during this time. Like memory foam, you’ll notice it’s pretty usable within the first few hours.


Casper also offers hybrid mattresses, combining memory foam, springs, and latex features. Hybrids tend to fall between memory foam and spring mattresses’ inflation time. You can expect a Casper hybrid mattress to inflate fully within 18 to 60 hours.

Latex Hybrid

Lastly, Casper offers latex hybrid mattresses, a blend of latex and spring features. Like hybrid mattresses, latex hybrids have a moderate inflation time. A Casper latex hybrid mattress usually takes 18 to 60 hours to reach its full size and comfort potential.

 What does Rezone mean if your Casper mattress won’t expand?

You got your Casper mattress and followed all the instructions. But it’s growing differently than you thought it would. That’s when you might hear the term “Rezone.” So, what does Rezone mean if your mattress won’t expand?

Rezone is a term used to describe a specific process designed to help a mattress expand when it’s not doing so. It moves your mattress in the right way.

Here’s what Rezone involves:

Massaging the Mattress

The first step in Rezone is massaging the areas of the mattress that are struggling to expand. Think of it as giving your mattress a friendly pat to encourage it. You can use your hands to apply gentle pressure to the areas that appear less puffy.

Allowing More Time

Sometimes, your Casper mattress may need more time to expand. If you rezone something, it doesn’t mean something is wrong. It has one more chance to find the right amount of comfort. 

Checking for Obstructions

Rezone also includes checking the mattress for any obstacles or things stopping it from expanding. It could mean getting rid of anything putting pressure on the mattress. 

Remember that Rezone is a valuable process that will help your mattress perform at its best. It’s not a sign that something is wrong with your mattress. Extra care and time are sometimes all it takes to ensure your mattress grows to the correct size and comfort.

Final Thoughts

You must be patient to get a great night’s sleep on your Casper mattress. Quality materials affect how your Casper mattress expands. It has intelligent shipping compression, air, and careful design.

While the wait may seem long, it’s worth it. The gradual expansion ensures that every mattress layer. Memory foam, latex, or springs can regain their intended shape. In other, you get the most relaxation and support possible.

Additionally, this waiting period contributes to the long-term durability of your mattress. It helps reduce any initial odors. So, even though it might feel like watching paint dry, the result is a good night’s sleep on a good mattress. So, relax, wait, and know that your mattress is working to make you sleep.
