Buying a new mattress can be tough. There are so many different brands and materials available on the market today that it can all become a bit overwhelming pretty quickly. You want to make sure that you’re making the best decision for yourself and your family. But, with all the options to choose from, how do you even know what’s best?

While we can’t handpick your mattress for you, we have done a bit of the hard work. We’ve compiled an in-depth comparison of the Casper vs Purple mattress, two of the popular options on the market today, comparing everything from the warranty and firmness, all the way down to the price, to help you decide which mattress, Purple vs Casper, is the absolute best for you.

Construction: What Are Purple and Casper Made From?

One of the main things to consider when shopping for a new mattress is what it’s made out of. Mattresses are available in an array of different materials these days. Everything from memory foam, to latex, to soybean or coconut husk foam—and even a mixture of several different materials.

All materials offer different qualities, levels of softness, and levels of firm support. One isn’t necessarily better than the other. But, it’s important to determine what mattress construction is best for you.

Purple Construction

The Original Purple Mattress has been scientifically engineered with four individual layers, harnessing the best qualities of a few different materials that all come together into one comfortable, supportive mattress.

The first layer you’ll find in this mattress is the Purple Smart Comfort Grid. The Comfort Grid has been specifically engineered to provide soft, cradling comfort in some areas while remaining firm and supportive exactly where you need it. The grid actually softens and relaxes under the pressure points of the body, such as the hips and shoulders to relieve pressure pain and stiffness, while the rest of the grid holds its shape and remains supportive. This allows the mattress to literally mold to your shape, size, and position, night after night.

Underneath the Smart Comfort Grid is a layer of plush comfort foam. This layer is constructed of a plush yet high-density polyurethane foam that is certified by Certi-PUR US. This core layer of the mattress is designed to boost the performance of the Comfort Grid above, allowing for increased comfort and even better responsiveness.

Bringing up the bottom of the Original Purple Mattress is a thick layer of high-density polyurethane support foam. This foam layer, which is also Certi-PUR US Certified, is medium-firm and provides overall structural support to the entire mattress, further enhancing the qualities of the above layers and providing durability and stability. The whole Purple Mattress is covered in a super-stretchy responsive knit cover that flexes and moves with the layer to ensure that you get the best performance out of the Smart Comfort Grid and provides a top layer of soft comfort to lay on.

Casper Construction

Casper has combined the best qualities of both memory foam and latex to come together into one satisfactory mattress. The top layer of the Casper is constructed with 4 individual layers of memory foam. These layers have been specifically constructed to mold around your body, relieving pressure points and joint pain while you sleep. The top layers of the Casper mattress feature zoned support to help guarantee that you’re getting the correct level of softness vs firmness in the correct areas. This also helps ensure a comfortable sleep by providing the proper neck and spinal alignment.

Bringing up the bottom of the Casper is a supportive layer of latex foam. This thick layer allows for overall reinforcement of the entire mattress and helps to ensure that you’re getting firm support where you need it.

Who Wins?

While the Casper mattress is definitely constructed with high-quality materials, in the overall construction of the Casper vs Purple mattress, we have to give Purple the win. The zoned support system of the Casper mattress doesn’t allow for a lot of position change and still remain supportive and comfortable. While the Comfort Grid featured in the Purple mattress in conjunction with the high-quality foam layers allows for comfort and support no matter how or where you lay.

Temperature Control: Purple vs Casper

No one wants to be left waking up hot and sweaty every morning, after a long night of tossing and turning, due to a mattress that sleeps way too hot. And in today’s world, it’s just not necessary anymore. More and more mattress companies are figuring out the best way to keep you cool and comfortable throughout the night. Mattresses are now equipped with anything from cool gel memory foam to perforated top layers to allow for ideal airflow, breathability, and temperature regulation.

So, when it comes down to Purple vs Casper, who has the best temperature control in their mattress?

Purple Temperature Control

The Original Purple Bed uses two different technologies to help guarantee that you sleep cool and comfortably every night.

The Smart Comfort Grid provides the first layer of heat retention defense. The grid is scientifically engineered and specifically constructed with an open design that is completely temperature neutral. This open grid allows for adequate airflow and breathability to ensure that the mattress never traps heat against your body. It is also designed to pull your natural body heat away from you and disperse it.

On top of the Smart Comfort Grid is the knit cover. This cover surrounds the Purple mattress and is designed to promote an extra level of airflow and breathability against your skin.

Casper Temperature Control

Casper actually utilizes every layer of their mattress to achieve optimal temperature regulation. The top layer of the Casper mattress is constructed with an open cell foam that actually harnesses the powers of convection and conduction to physically move the heat away from your body as you sleep. Underneath that is the layer of memory foam that provides satisfactory airflow and breathability throughout the mattress. This layer extracts heat from the top layer of the mattress.

The bottom layer of latex foam actually absorbs the heat that is pulled away from the top layers and distributes it evenly through the bottom of your mattress, away from your body. This overall setup not only quickly wicks away your natural body heat, but actually makes for a significantly cooler sleeping surface.

Who Wins?

When we consider the temperature regulating properties of Purple vs Casper, Casper definitely takes the win. Purple certainly does equip their mattress with cooling qualities. But, Casper utilizes every layer of their mattress to not only do away with naturally occurring body heat but to actually make the surface of the mattress cooler.

Firmness vs Softness

Everyone is different when it comes to the firmness to softness ratio that they prefer in their mattress. Those that battle with back pain regularly often looks for a firmer mattress that will provide them with the utmost support through the night. Others may prefer a soft, plush, cradling mattress that will relieve pressure points and achy joints.

Unless you have a specific reason to lean more towards one extreme or the other, most people tend to sleep best on something that’s right in between. The most common mattress will lend a perfect balance of firm support and just right softness.

In the Casper vs Purple mattress, which one hit that perfect proportion of plush comfort and stable support?

Purple Firmness

The Original Purple Bed is considered a medium-firm mattress. Due to the unique construction of the smart Comfort Grid, the Purple mattress is able to provide you with a truly soft, comfortable firmness in a way that other mattresses can’t.

Their comfort Grid is specifically made to collapse under pressure points such as the hips, shoulders, and head. With the layers of soft high-density foam beneath the grid, your joints and pressure points are left cradled and molded to avoid any stiffness or pain upon waking. However, the rest of the grid, combined with the bottom layer of firm high-density polyurethane foam ensures that you still receive adequate firmness and support in all the places that you need it.

Some mattresses feature “zoned firmness”, where the company has added an extra layer of firm material where they think you’ll need it, the Purple actually adapts to your body position night after night. Relaxing where you need it, remaining firm everywhere else, and bouncing back to its original shape every morning.

While it is considered a medium-firm mattress, and it does provide firm support on certain areas of the body, the Purple mattress is not considered an all-around firm mattress and may become too soft under pressure points for some sleepers.

Casper Firmness

The Casper mattress is also described as a medium-firm mattress. One of Casper’s primary construction materials is memory foam, which is certainly not known for its overall firmness. However, the memory foam layer is backed up by a thick layer of latex foam that helps to provide that firm support that a lot of sleepers are looking for in a mattress.

The combination of the two materials allows for a soft, plush, comfortable top layer, while still providing stable support and firmness underneath.

Who Wins?

When it comes to the firmness of the Casper vs Purple mattress, Purple certainly takes the win. While Casper reviewers do like the ration of softness to firmness in the Casper mattress, the Smart Comfort Grid in combination with the high-quality base foam construction gives Purple the leg up in this category.

Price: Casper vs Purple

While many important factors go into making that final purchase of your brand-new mattress, one of the most important is how hard it’s going to hit your wallet. You want something of high-quality that’s going to keep you comfortable and cool and last you a good long while. But, you certainly don’t want it to break the bank if it doesn’t have to.

When we consider the price of a Casper vs Purple mattress, who’s going to give you the best price?


The Original Purple Mattress will cost you $899 for a full-size, $999 for a queen-size, and $1299 for a king or California king size mattress. When it comes to the average price of a new mattress, The Original Purple Bed lands somewhere in the middle. Of course, there are always cheaper and more expensive options available on the market. But, given the qualities of the Purple mattress, it’s a fairly neutral price point, and you can upgrade to a California king for the same price.


The Casper mattress will run you $805.50 for a full-size mattress, $895.50 for a queen-size, and $1075.50 for a king. Again, these are fairly run of the mill prices for a decent mattress with adequate firmness, temperature regulating properties, and high-quality construction.

Who Wins?

When it comes to Purple vs Casper, Casper takes the overall win on price with a savings of nearly $100 with each size upgrade. However, it could serve to keep in mind that you can upgrade to a California king size Purple mattress for the same size as their standard king-size option.

Pros & Cons of Purple vs Casper

You can research all day, combing through website after website for all of the technical details on the mattresses you’re considering. But, when it comes down to it, experience speaks louder than technical details.

The best way to really determine how well your potential new mattress is going to perform is to take a look and see how well it performed for those that have already bought it. You’ll get a bit of firsthand experience and opinions before you ever spend a dime.

So, what did reviewers have to say about the Casper vs Purple mattress?

What Do Reviewers Love About Purple?

Reviewers have a lot of wonderful things to say about The Original Purple mattress. However, the biggest selling point with those that have already purchased and love their Purple mattress seems to be the pressure point relief.

According to the reviewers of the mattress, the Purple really does deliver on its promise to provide cradling joint and pressure point relief while still remaining firm and supportive over the rest of your body. Reviewers love the fact that the Comfort Grid actually adapts and responds to your body and movements, allowing for adequate pressure relief exactly where you need it, no matter which sleeping position you end up in. Many reviewers have even mentioned the fact that they have severe arthritis or chronic back pain issues and The Original Purple Bed does a wonderful job at relieving their pain and allowing them to wake up stiffness and pain-free.

Overall Pros

  • The Purple mattress is comfortable and supportive for all sleep positions
  • Reviewers hail that the Purple mattress actually keeps you cool throughout the night
  • The Smart Comfort Grid is specifically designed to hold up to regular wear and tear, making the Original Purple Bed durable
  • The combination of the Comfort Grid and the high-quality foam makes the mattress extremely responsive and allows it to bounce back to its original shape quickly
  • The Purple company offers a good warranty and sleep trial

What Are The Drawbacks Of Purple?

One of the biggest complaints about the Original Purple Bed is that the support system doesn’t perform well for people that are extra large or extra petite. Larger sleepers have noticed that the support grid tends to simply collapse under them and the following layers of foam don’t offer enough support to keep them from just sinking into the mattress. While small framed sleepers have noted that the Comfort Grid doesn’t actually work under their light weight. Instead of folding in on itself to cradle pressure points and joints like it’s supposed to, if you’re of a small weight, the grid just remains upright, leaving you to sleep on a too-firm, uncomfortable surface.

Overall Cons

  • The Purple doesn’t offer a lot of edge support, especially for sleepers of a heavier weight
  • The Purple company has noted that it can take up to 30 days for your body to adjust to the Original Purple Bed and you may experience discomfort or pain during this time
  • The Purple mattress must be used on a very supportive bed frame or box foundation to perform correctly and to guarantee your warranty
  • It is not recommended to use the Purple mattress on a conventional box spring, as the spring may break down and cause sagging, damaging the integrity of the mattress.

What Do Reviewers Love About Casper?

Reviewers rave about that perfect ratio of softness vs firmness in the Casper mattress. Not unlike the Purple mattress, Casper has provided its consumers with a just-right level of firmness where they need it and soft comfort in all the right places. Many reviewers have mentioned that they suffer from arthritis or chronic pain issues, and the Casper mattress ha allowed them to wake up refreshed and without pain or stiffness.

Overall Pros

  • The Casper mattress is equipped with several layers of heat retention defense
  • Reviewers rave about Casper’s timely and friendly customer service
  • The Casper mattress provides lots of amenities without breaking the bank
  • According to many reviewers, the Casper mattress provides that “just right” level of firmness
  • The Casper company offers a decent sleep trial and warranty on their products

What Are The Drawbacks Of Casper?

While most reviewers seem to be satisfied the overall performance of the Casper mattress, many have noticed that the Casper has a lingering off-gassing odor. While it’s common for foam mattresses that have been vacuum sealed to have a noticeable smell upon opening, it usually dissipates quickly with adequate ventilation. However, some Casper consumers have reported that the “chemical smell” has lingered on their mattress for upwards of weeks to even months.

Overall Cons

  • Due to the way the Casper mattress is packaged and shipped, it can take up to a full 72-hours for the mattress to fully expand and be ready for use
  • There is virtually no edge support in the Casper mattress, which could lead to issues with rolling off the bed, sitting on the edge, or for larger framed sleepers
  • While reviewers love the perfect firmness of the Casper, some have noted that when sleeping with a partner, the mattress has a tendency to lean to one side
  • Some consumers have reported that the Casper mattress lacks durability, wearing down and offering less support in as little as 6 months

Warranty: Purple vs Casper

The fact of the matter is, you want to know for sure that the mattress you’re purchasing is of high-quality, and you certainly want to guarantee that you won’t be left footing the bill if it turns out that it’s not up to par after all.

A good company will offer a good warranty on their product simply because they trust it to be a good product. They will happily back up their mattress and repair or replace it if necessary.

When we considered Purple vs Casper, which company offered the very best warranty for their mattress?


The Purple Company offers a 100-night risk-free sleep trial as well as a 10-year limited warranty. If you don’t love your Purple mattress within the 100-night trial period, then Purple will pick up the mattress from your home and give you a full refund on your purchase.

If you decide to keep your Purple mattress after the 100-night sleep trial period, you will still receive a 10-year limited warranty from the Purple company. This warranty guarantees that the company will repair or replace (at their discretion) your mattress if the damage meets the terms of their warranty. This includes an indention greater than 1” or any splits, cracks, or failures of the material so long as the mattress has been used properly. The 10-year warranty will not cover any damage that is a result of improper use or abuse by the owner.


When the folks at Casper founded their mattress company, one of their main goals was to allow consumers to try their product for a sufficient amount of time before they were forced to make any final purchasing decisions. So, Casper offers a 100-+night risk-free sleep trial when you purchase their mattress. If you’re not completely satisfied within 100 nights, they will refund your full purchase price and pick up the mattress themselves.

If you decide you do love your Casper mattress, you will remain covered for 10 years with a limited warranty from Casper. This warranty, like most others, covers any indentions in the mattress that are greater than an inch, and damage, splitting, or cracks in the material, and any defects within the zipper mechanism. Of course, the warranty does not cover the improper use of the product or any strenuous abuse.

Who Wins?

When it comes to the Casper vs Purple mattress warranty, there really isn’t a definitive winner for this category. Both the Casper and the Purple mattress company offer a 100-night risk-free trial period as well as a 10-year limited warranty that covers basically the same damages and conditions.

About The Companies

Learning a bit about the company you’re buying from isn’t necessarily crucial to your decision. But, it can be nice to have a bit of background when you’re still up in the air. How long has the company been in business? How did they get their start? Have they won any awards or accreditations?

The Purple Company

The Purple mattress company was founded n 2013 by two brother, Tony and Terry Pearce. Tony Pearce is literally a rocket scientist and Terry is considered a comfort tech genius. Between the two of them, they started working on the inventions and technologies that would be needed to eventually form the Purple mattress in 1989. By 1993 the Pearce Brother’s invention of Floam was being used in everything from wheelchair seats to preemie baby nests. In 2013 the brothers decided to make mattresses. It wasn’t until 2016 that they get all their ducks in a row, created a patent pending machine called the Mattress Max and started producing the Purple mattresses that we know today.

The Casper Company

In 2014 five individuals came together to create what is now known as the Casper mattress company. They weren’t happy with the way people were expected to shop for and purchase a mattress. They felt like the bright showrooms and pushy salesmen just didn’t make for a comfortable environment to decide on the mattress you wanted to sleep on night after night. So, they decided to change the way that we buy mattresses.

They created the Casper mattress company that sells online directly to the customer to cut out the middleman experience as well as the middleman costs. Since their founding in 2014, Casper has been recognized by Good Morning America, Forbes, and The New York Times. In 2017, they were named one of the most innovative companies by Fast Company and received Good Housekeeping’s Lab Pick in 2018.

So, What’s The Final Conclusion?

When it comes down to who takes the win in our individual categories, Purple and Casper are pretty much tied. However, we think that the Smart comfort Grid really gives the Purple mattress just the slightest leg up in this comparison. The Comfort Grid allows for every sleeper, no matter their position, to be comfortable, cradled and supportive across the entire surface of the mattress.

So, if you’re looking for a mattress that will respond to your body perfectly night and night, no matter which position you land on, then Purple is a fantastic choice for you.
