When you purchase a Casper mattress, it generally takes between a few hours to 72 hours to fully expand. However, most customers report that their mattress feels ready for sleep within just a few hours after unboxing. The complete expansion and firmness level can vary slightly based on room temperature and the mattress’s composition.
Factors Impacting Casper Mattress Expansion Time
The time it takes for a Casper mattress to expand can be influenced by various factors. It’s important to understand what can affect this process to ensure that your mattress is set up for the best possible sleep experience.
Temperature
Room temperature plays a significant role in the expansion time of a memory foam mattress. Memory foam responds to heat, and in a colder room, it will take longer for the mattress to reach its full size. A warmer room accelerates the expansion process, so if you want your Casper mattress to expand more quickly, consider increasing the room temperature slightly.
Size and Thickness of the Mattress
The thicker and larger the mattress, the longer it may take to fully expand. A Casper king-sized mattress with a higher profile might need more time compared to a twin-sized model or one with a lower profile.
Shipping and Storage Conditions
How long your Casper mattress was compressed in its box during shipping and storage can also impact the expansion time. If the mattress has been rolled up for an extended period, it might need more time to decompress.
Product Line Variations
Casper offers different mattress models, each with unique layer constructions. Some may have additional materials or higher-density foams that affect the time required for full expansion.
Setting Up Your Casper Mattress for Expansion
To maximize the efficiency of the expansion process, you should set up your Casper mattress properly. Here’s what you need to do:
Unbox Your Mattress Promptly
It’s advisable to take your Casper mattress out of the box as soon as possible. This not only reduces the risk of prolonged compression but also starts the expansion process immediately.
Place It on the Right Foundation
Lay your mattress on a flat, sturdy, and breathable base. Ensure that the foundation supports the mattress evenly, as uneven surfaces can hinder expansion and affect the mattress’s performance.
Give It Space
Make sure there’s ample room for your mattress to expand—avoid cramming it into a tight space. Airflow around the mattress aids in expansion and helps to dissipate any “new mattress” smell more quickly.
Tips for the First 72 Hours After Unboxing
The first few days after unboxing are crucial for your Casper mattress to expand and off-gas. Here are some additional tips to ensure this process goes smoothly:
Avoid Sleeping on It Immediately
Although it can be tempting to sleep on your brand-new mattress right away, it’s best to give it a little time to fully expand and air out. If you can, wait a few hours before sleeping on it to enjoy the optimum comfort and support it was designed to offer.
Do Not Disturb
Resist the temptation to press down or walk on the mattress as it expands. This can interfere with the foam’s natural expansion process and potentially damage the mattress.
Provide Ventilation
Keep the room well-ventilated by opening windows or using a fan. This helps clear out new mattress odors and moisture, which can accompany the unboxing.
Understanding Off-Gassing in Memory Foam Mattresses
New mattresses often emit an initial odor known as off-gassing. This is due to the release of volatile organic compounds (VOCs) that were contained within the packaging materials and the foam itself.

Off-gassing is usually not harmful, though it can be unpleasant for some people. The smell tends to diminish significantly within a few days.
Minimizing Off-Gassing Smells
To minimize the odor, keep your mattress in a well-ventilated area and avoid using it immediately. You might also choose to use a mattress protector or fitted sheet to cover the mattress after it’s fully expanded to help contain any residual odors.
Regular Care and Maintenance for Your Casper Mattress
Proper care can extend the life of your mattress and ensure it remains comfortable and supportive.
Rotating Your Mattress
Casper recommends rotating the mattress 180 degrees every few months to promote even wear and prolong mattress life. However, flipping is not advised as the layers are designed with a specific order in mind.
Cleaning and Protecting
Using a mattress protector from the start can help shield your mattress from spills, stains, and other damages. When cleaning your mattress, spot clean any stains with a mild detergent and avoid soaking the foam layers.
Finishing Thoughts
Setting up and waiting for your Casper mattress to fully expand can be a test of patience, but it’s a crucial step in making the most out of your new investment. By following the setup guidelines and allowing the full 72 hours for expansion – even though you may be able to sleep on it sooner – you’ll be ensuring that your mattress performs at its best for years to come. Remember that the expansion and off-gassing processes are normal and expected parts of getting a new mattress, and with a little time, you’ll be on your way to enjoying restful, supportive sleep every night.
