Key Points

  • The Casper Mattress is an all-foam mattress made of polyfoam and memory foam, providing support and pressure relief.

  • It's most suitable for back and side sleepers.

  • It features perforated AirScape® foam for temperature regulation and improved breathability.

  • While the Casper Mattress excels in motion isolation, its edge support is weaker, and it may not be ideal for stomach sleepers or those over 230 pounds.

Some sleepers have simple needs. Why buy an extravagant Purple Mattress or the futuristic "smart" mattress that came out in 2022? If you're looking for an all-around quality mattress that does its job well, meet the Casper Mattress. It's an all-foam champ blending polyfoam and memory foam that most back and side sleepers can easily fall in love with.

With its innovative AirScape® foam, the Casper Mattress ensures cooler, more breathable nights. It's also an expert in motion isolation, albeit a bit lackluster in edge support. Though it's not perfect for stomach sleepers or those over 230 pounds, for many, it hits that Goldilocks "just right" mark.

This article dives into the specifics of the Casper Mattress, demonstrating that simple is sometimes superior.

How To Choose a Mattress

Choosing a mattress can be tough. Start by assessing the construction of the mattress you're considering, as all-foam, innerspring, and hybrid varieties offer distinct differences in support and comfort. The material of the comfort layer has a huge impact as well. While memory foam contours to your body, latex is bouncy and firm. Consider the firmness level that meets your needs, as this greatly influences your quality of sleep.

Remember that your sleep position — back, side, or stomach — plays a huge role in what kind of mattress you need. Back sleepers need a mattress on the medium-firm side to keep their spine in healthy alignment, while side sleepers need a slightly softer mattress to allow their shoulders and hips to sink in and remain aligned throughout the night. Meanwhile, stomach sleepers need a firmer mattress to ensure they don't sink in too far and feel like they're being suffocated.

When looking for a new mattress, make sure that you research trial periods, warranties, and return policies, as these can have a significant impact on your experience with the product. Also, decide whether you prefer to shop online or in-store, as each approach has its pros and cons. Shopping online offers convenience and the ability to compare multiple options at once, while in-store shopping allows you to physically try the mattress before purchasing. Whichever one you choose, knowing what to look for when shopping for a mattress helps you make an informed decision that will lead to a better night's sleep.

Casper Mattress Performance

The all-foam Casper Mattress provides superior pressure relief and support. Its perforated AirScape® foam regulates temperature for a cooler sleep experience. However, while the mattress excels in motion isolation, it falls short in terms of edge support.

The Construction of the Casper Mattress

The Casper Mattress is made entirely of foam and has a straightforward layer construction:

  • The top layer of polyfoam contours to your body, providing much-needed pressure relief, while the perforation in the foam allows for airflow and prevents the buildup of excessive heat or humidity.

  • The second layer is made of memory foam, which is designed to contour closely to your body.

  • The final support layer is a thick and dense polyfoam that forms the base of the mattress, which prevents you from sinking too far into the mattress and promotes healthy spinal alignment.

The Casper Mattress has no zoned areas, meaning there's no reinforcing around the edges of the mattress or the lumbar area. If you prioritize back support or often sleep or sit on the edge of your mattress, the Casper Mattress may not excel in these areas.

Temperature Regulation and AirScape® Foam

Overheating can disrupt your sleep, and Casper understands this. Physician James Hamblin specializes in preventative medicine and public health. He told The Atlantic that people "found that they slept longer in temperatures of 61 degrees Fahrenheit versus 75 degrees."

The Casper Mattress is designed with temperature regulation in mind, using the perforated AirScape® foam to enhance breathability and dissipate heat for a more comfortable night's sleep. This design maintains a cooler sleep environment, promoting better sleep.

While a perforated upper foam layer is desirable, foam mattresses sleep hotter than all other mattress types. This is the unfortunate reality when it comes to foam mattresses — they build up heat no matter what. There are other ways to sleep cool, such as choosing the right pillows and bedding.

Motion Isolation

The Casper Mattress excels in motion isolation, thanks to its layered foam construction. The foam layers work together to minimize motion transfer, ensuring that you won't be disturbed by any movements from your sleep partner. The Casper Mattress provides reliable motion isolation, allowing you to enjoy a restful night's sleep.

Edge Support

Edge support is an area where the Casper Mattress falls short. The lack of reinforcement means that the mattress may not provide adequate support and stability around the edges or the lumbar area. This could be problematic for individuals who require strong edge support or frequently sit or sleep on the edge of the mattress (or if they're pushed there by a space-hogging bed partner or pet). It's important to consider this aspect if edge support is a priority for you.

Why Choose the Casper Mattress

The Casper Mattress is a strong choice for a wide range of sleepers, including back and side sleepers, who will appreciate the medium-firm feel of the mattress. However, stomach sleepers, especially those over 230 pounds, may find that the Casper Mattress isn't right for them. Stomach sleepers run the risk of sinking too far into the mattress, thereby throwing their spine out of alignment and making them feel like the foam layers are suffocating them.

While the Casper Mattress offers a wealth of advantages, it may not be suitable for individuals seeking an extremely firm or soft mattress, since it falls within the medium-firm range. Furthermore, those with a limited budget might find the Casper Mattress to be too costly, especially for an all-foam mattress. If that's the case for you, explore budget-friendly alternatives.

Overall, the Casper Mattress is a solid all-foam mattress that comes with all the pluses and minuses commonly associated with that category.

Pros and Cons of the Casper Mattress

Knowing the advantages and disadvantages of this popular all-foam mattress, from its excellent pressure relief and motion isolation to its weaker edge support and potential issues for certain sleep positions, helps you decide whether it's the right one for you.


  • The polyfoam and memory foam layers provide good pressure relief.

  • As with most all-foam mattresses, the Casper Mattress isolates motion well.

  • The combination of the memory foam and the denser bottom layer of foam provides support and healthy spinal alignment.

  • The perforated AirScape® foam helps with temperature regulation.

  • Medium-firm feel is good for back and side sleepers.


  • The edges aren't zoned, so edge support performance is fairly weak.

  • Because all of the layers are made of foam, it's difficult to move around on the surface of the mattress.

  • The mattress might be too soft for stomach sleepers and/or sleepers over 230 pounds.

Final Thoughts on the Casper Mattress

The Casper Mattress boasts a mix of interesting designs and materials that work together to provide a good sleep experience. Each layer serves a unique purpose, and the different types of foam ensure that you receive the ideal mix of support and pressure relief. The mattress also features airflow and cooling technology, which allows you to remain comfortably cool throughout the night, preventing heat-related discomfort that can disrupt your slumber. However, it's important to keep in mind that all-foam mattresses, by their very nature, sleep hotter than other mattresses.

This mattress provides good pressure relief, effectively isolates motion, and promotes proper spinal alignment. It also features perforated AirScape® foam for temperature regulation, ensuring a comfortable sleep environment. With its medium-firm feel, it's particularly well-suited for back and side sleepers. These qualities make the Casper Mattress an attractive choice for those seeking a supportive and comfortable sleep environment.

Lastly, Casper's customer-focused policies further solidify their commitment to providing an exceptional sleep experience. With a 100-night sleep trial, a limited 10-year warranty, and top-notch customer service, you can feel confident in your purchase.
