Although one is a household name while the other is an underrated newcomer, Casper and Puffy are both reputable online mattress companies who offer some of the best memory foam mattresses on the market. Since its launch in 2014, Casper has consistently maintained its reputation as a leader and trendsetter in the mattress startup sphere. Puffy, on the other hand, has only been around since 2017, but is already proven a formidable competitor due to its high-quality materials and versatile design.

Both Casper and Puffy manufacture a number of multi-layer memory foam mattresses intended to eliminate issues commonly associated with memory foam. Casper has three selections ranging in price-point, number of layers, and luxury add-ons, whereas Puffy has two. For the purposes of this comparison, we’ll just be focusing on the companies’ flagship models: the original Casper and the Puffy.

While both mattresses aim to enhance the comfort of traditional memory foam with the firmness, support, and cooling properties of other types of mattresses, they contain significant differences. In this guide, we’ll break down what those are and help you decide on the one that best suits your needs.

Mattress Construction Comparison


The Puffy is made out of three distinct foam layers that come out to a total of 10 inches. At the top sits a two-inch comfort layer made out of memory foam. Unlike traditional mattresses made out of this material, Puffy’s memory foam comfort layer is infused with a Cooling Cloud Gel that pulls away your body heat while responding to your body’s pressure points and weight distribution for adaptive support.

Underneath, another two-inch layer is made out of ClimateComfort polyfoam, which resists temperature changes that come with the seasons and keeps the mattress at a comfortable temperature regardless of what time of year it is. All of this sits on top of a six-inch support layer of firm-set polyfoam that provides exceptional durability and firmness for a memory foam mattress. It’s designed with versatility in mind, making it suitable for all sleeping positions and support needs. Puffy’s website also states it can be used on top of any stable surface.

The Casper is made out of four distinct foam layers that add up to a total of 9.5 inches. At the top sits a one-and-a-half-inch comfort layer made out of open-cell foam, which works to keep the mattress bouncy, breathable, and combating the heat-trapping properties traditional formemory foam. Underneath, another one-and-a-half-inch layer made out of high-density memory foam provides the mattress with contouring and pressure relief. This is followed by a one-and-a-half-inch layer of transition foam that offers bounce and zoned support, with more softness near the shoulders and firmness near the hips. All of this sits on top of a five-inch thick base layer of polyfoam that provides  a solid amount of support.

The Casper also has the option for a hybrid technology add-on. This tacks on a base layer of inner springs that add lift, edge support, and additional cooling properties not found in other memory foam mattresses.

Firmness Comparison

Firmness is the most important aspect when it comes to shopping for a mattress, because it’s the first step to determining how comfortable you’ll be during sleep. Since everyone prefers different levels of firmness and softness, and these definitions even differ from person to person, what a “good” level of firmness is depends entirely on your specific needs. For the sake of quantifying and qualifying firmness, we use the same 1-10 scale to rank all mattresses on this site, with 1 being extremely soft and 10 being extremely firm. Side sleepers may want mattresses around the 2-3 firmness scale for maximum cushioning around their pressure points, while heavier sleepers and those who sleep on their back and sides may prefer mattresses rated a 7-10 in firmness.

Generally speaking, most people will find medium-firm mattresses (4-6 on the scale) the most accommodating of a wide range of needs. Being each made of layered foam over a thick polyfoam support layer, both the Casper and the Puffy fall in this category. This puts them at around the same level of comfort and support, allowing them both to provide contouring and cushioning for pressure point relief while preventing too much sinkage. Since the Puffy’s support layer is 1 inch thicker than Casper’s and is made out of a firm-set, supportive base, it scores a 5-5.5 on the firmness scale, with the Casper scoring a 4.

The mattresses’ firmness also depends on the position and location of your body. The Casper’s zoned support layers means it’s softer around the shoulders and firmer around the hips, while the Puffy’s adjusts its firmness and softness depending on your weight distribution.

Sleep Experience

While firmness is a major factor when it comes to choosing a mattress, it’s just one thing that affects how comfortable you’ll be throughout the night. You should also take into account the features that determine the rest of your sleep experience: temperature control, motion transfer, responsiveness, resilience and bounce, edge support, and off-gassing and smell. These affect everything from how hot you’ll sleep, to whether you’ll be disturbed by the movement of your partner, to how suitable the mattress is for sex.

Temperature Control

Whether you tend to sleep hot, or simply want a bed that stays cool and comfortable throughout the night, temperature control is an important detail that shouldn’t be overlooked. This is especially true for memory foam mattresses, which traditionally trap heat due to the material’s high density and conforming properties. Luckily, both Casper and Puffy are designed to counteract this.

Casper’s open-cell foam comfort layer is unusually bouncy for memory foam, which keeps the air flowing and reduces the type of sinkage that causes and traps heat. Meanwhile, Puffy’s top two layers are both geared towards temperature control: Its top-most comfort layer is infused with a cooling gel and paired with a second layer that resists seasonal temperature changes to maintain the same temperature year-round.

Both the Casper and the Puffy are solid choices for keeping sleepers cool, but we’d rank the Puffy slightly higher due to its climate-responsive warming effect in the winter.

Motion Transfer

An important detail if you plan on sharing your bed, motion transfer dictates how much you’ll be able to feel your bedmate’s movements throughout the night. If one or both of you tend to toss and turn, or if you happen to be a light sleeper, then you’ll want to go with a bed that offers good motion isolation.

Traditionally, memory foam is an excellent material for this. The Casper, however, is built with more bounce and responsiveness than typical memory foam mattresses, so your sleep may still be disturbed by your partner’s movements. Meanwhile, the Puffy’s comfort layer is made out of a soft memory foam that offers superior motion isolation. Therefore, we’d recommend the Puffy over the Casper if motion transfer is important to you.


A mattress’ responsiveness refers to  how quickly it adapts to changes in pressure, which determines whether your weight will be adequately supported when you switch to a new sleeping position. This is especially important if you tend to shift your weight a lot when you sleep.

The Casper’s zoned support levels, paired with its memory and open-cell foam comfort layers, give sleepers targeted support and pressure-point relief. The Puffy’s comfort and support layers are also highly adaptive to the sleeper’s weight. Therefore, we’d rank the two mattresses the same when it comes to responsiveness.

Resilience and Bounce

How easily a mattress can “bounce back” to its original firmness depends on its resilience. Not only do mattresses with high resilience make it easier to have sex and switch sleep positions in bed, but they also are also less likely to lose their shape or start sagging over time.

Traditional memory foam mattresses have pretty limited resilience, and the Puffy, which incorporates the material in its comfort layer, is no exception. The Casper, on the other hand, is known for its unique bounce, so we’d suggest it over the Puffy when it comes to resilience.

Edge Support

Just as the name implies, a mattress’ edge support dictates how much you’ll be supported if you sit or sleep near the border. This is important even if you tend to sleep near the middle of the mattress because you’ll have to move over the edge every time you get out of bed. Due to their softness and signature “sinkage,” memory foam mattresses traditionally offer poor edge support, and this sagging can get even worse over time due to compression without proper support.

Unfortunately, neither the Casper nor the Puffy provides more edge support than the average memory foam mattress. That said, Casper’s “hybrid technology” option does provide a perimeter of added edge support for an additional $200. Because of that, we’d rank the Casper over the Puffy when it comes to this feature.

Off-gassing and Smell

When you first unwrap your mattress, you may experience an odor coming off of it that lingers for anywhere from a few hours to a few days. This is called off-gassing and could make for an uncomfortable sleeping experience if you plan to use your mattress immediately. Casper’s off-gassing smell only lasts for a few hours, while Puffy’s can remain up to a few days, so we’d suggest you go with the Casper over the Puffy if the smell is an important factor.


Shipping, Trial, Warranty, and Returns

While the sleep experience provided by a mattress should trump all else, you should still take a company’s shipping, trial, warranty, and return policies into account. This way, you can make sure you get to try out a mattress before you make a commitment and return it hassle-free if you find out it’s not for you. Additionally, whether the company will replace your mattress for life or only after a few years can make a huge difference in the long run when it comes to your final price tag.

Prices, Sizes, and Value

While price isn’t as important as the factors that determine your sleep experience, you should still keep it in mind when shopping for a mattress. You want to make sure you’re getting a good deal while staying within your budget, and price can make or break a choice if you’re comparing two incredibly similar mattresses.

Mattress SizePuffyCasper
Twin XL$825$695
California King$1,350$1,295

If we’re simply looking at the price-tags of their individual mattresses, Puffy is the more expensive choice. On average, Puffy’s flagship model costs around $100 more than its Casper equivalent, with this price difference going up to $200 when it comes to smaller sizes.

That said, this doesn’t necessarily mean Puffy is more expensive overall. If we take into account such variables as the different companies’ warranties, luxury add-ons, and white-glove delivery options, the difference gets a lot murkier. For one, Puffy comes with a lifetime warranty while Casper’s is only 10 years long, so you may find the $100 – 200 price difference worth it if you don’t want to have to purchase another mattress after 10 years. Meanwhile, Casper’s flagship model gives you the option of a $200 hybrid add-on that gives your memory foam mattress additional cooling properties and innerspring support, while Puffy doesn’t. Finally, you can tack on another $149 to Casper’s price-tag if you opt for its white glove delivery service, which comes with free mattress removal, neither of which Puffy offers as an option.

Which one ends up being more expensive in the long-run, and whether the more expensive one is more worth it, depends entirely on which mattress better suits your needs.


Puffy vs. Casper Mattress – Which One Should You Buy

Even with all of these factors in mind, you still might find it tough to make a final choice between Puffy and Casper. We’ve summarized these two mattresses’ main differences so that you can easily refer to it while deciding which mattress is the best for you.

Buy the Puffy mattress if you:

1. Want superior motion isolation

Puffy’s memory foam comfort layer offers better motion isolation than Casper, which is unique for having more bounce and resilience than the average memory foam mattress. This makes it an excellent choice for sensitive sleepers who have partners that toss and turn.

2. Want more responsive temperature control

Unlike most memory foam mattresses, Puffy has not one but two layers designed to regulate temperature. Not only will the mattress stay at a comfortable temperature throughout the night, but it will also offer either cooling or warming properties depending on seasonal changes in temperature.

3. Want a lifetime warranty

Unlike the Casper, which only offers a 10-year limited warranty, the Puffy comes with a lifetime warranty so that you can get your mattress replaced whenever you need it.


Buy the Casper mattress if you:

1. Want a bouncier and more resilient mattress

The Casper is famous for its unique bounce and resilience, which it has over both traditional memory foam mattresses and the Puffy. This makes it an excellent choice for active sleepers and sexual activity.

2. Want a memory foam mattress with edge support

The vast majority of memory foam mattresses have poor edge support, so the enforced edge offered by Casper’s optional hybrid add-on definitely gives it a huge advantage. Keep in mind that this will set you back an extra $200, although you’ll also get enhanced support, a pocketed coil support core, and additional cooling properties.

3. Need a brand with a more established reputation

Because Casper has been around for about three years longer than Puffy, you’ll be able to draw from a lot more reviews and journalistic coverage when doing your research. It’s also the more famous brand by far, and its mattresses have been around long enough for customers to give feedback on their durability.
