Puffy Lux vs Casper Mattress Comparison

It’s high noon, which means it’s time for another showdown between two high-quality mattresses! Today’s comparison pits Puffy’s medium soft luxury mattress—the Puffy Lux—against the medium firmness of the original Casper mattress. To achieve their varying degrees of softness, the Puffy Lux turns to layered memory foam, while the Casper uses a combination of memory foam, latex, and heavy-duty poly foam.

We’ll be discussing these differing textures, as well as the similarities between each mattress, their pros and cons, feel, construction, prices, and policies. By the time you’re done reading, you’ll hopefully have a strong idea of which new mattress is best for you and your sleeping needs.

Puffy Lux vs Casper: Similarities and Differences

Before we get too far, let’s outline a few of the more notable similarities and differences between the two mattresses. Because of their different foams, each one will likely appeal to a different type of sleeper. For further details, I recommend reading the full Puffy Lux mattress review and Casper mattress review.

Main Similarities 

  • Both mattresses are made entirely of foam, meaning that they don’t include any pocketed or innerspring support coils.
  • Although the type of foam differs layer by layer, both mattresses make extensive use of memory foam and poly foam.
  • Neither bed may be quite right for heavy people, who might be in need of the firmness and stronger support offered by innerspring mattresses. 
  • Strict stomach sleepers may not find what they need in either mattress. The Puffy Lux could lead to their hips sinking too far into the bed, and the Casper—while slightly better suited for stomach sleepers—probably doesn’t have the right level of firmness. We’d recommend checking out our best mattresses for stomach sleepers.

Main Differences 

  • Casper’s zoned support system and medium firmness make it a better fit for back sleepers and combination sleepers. Side sleepers will likely find more comfort in the softness of Puffy Lux’s gentle memory foam.
  • While the Casper only has one layer of memory foam and is good for hot sleepers, the Puffy Lux has a top layer of Cooling Cloud Foam that allows it to sleep just a bit cooler. Both options should work for hot sleepers, but if temperature is a high priority for you, it’s probably best to go with the Puffy Lux
  • For those factoring in price, the Casper is less expensive than the Puffy Lux.
  • Even though both mattresses do a decent job at isolating motion, Puffy Lux’s thick memory foam means partners are less likely to disturb one another while sleeping.

Which is Better for You?

Let’s briefly break down what kinds of sleepers each bed might be good for. Remember, the right mattress for you will depend on your body weight, height, and preferred sleeping position.

  • If you’re a back sleeper or a combination sleeper you’ll likely prefer Casper because of its firmness and the design’s ability to lift the sleeper up and out of the structure.
  • If you’re a side sleeper the Puffy Lux could be a better fit because of its extra softness, which gives the sinkage and contouring needed for pressure relief at the hips and shoulders.
  • If you sleep hot the Puffy Lux has a slight edge over the Casper because of its top layer of Cooling Cloud Foam. That being said, the Casper’s top layer of aerated foam promotes cooling breathability that should also be comforting for hot sleepers.
  • If you sleep with a partner both mattresses should work, although the Puffy Lux has a thicker and more abundant memory foam that makes for stronger motion isolation. 

Puffy and Casper Feel Comparison

Now that you know the basics about both mattresses, let’s go into greater detail about how each of them feels.

Puffy Lux Vs Casper Firmness
The Puffy Lux is much softer than the Casper.

Puffy Lux 

Of the two foam beds, the Puffy Lux is definitely softer. I’d rank it at about 5.5 out of 10 on the firmness scale

This places the Puffy Lux in the medium-soft category, indicating that it will likely focus more on hug and contour, with slightly less bounce and mobility. While the form-fitting should be a good match for side sleepers, back sleepers may need more support and combo sleepers could have a tough time changing positions. Strict stomach sleepers might also experience back pain from sinking too far into the bed.

But it’s also important to note that the Puffy Lux does offer some support. The firmer bottom foam layers in the Lux construction do create a foundation throughout the surface level of the bed. This mattress doesn’t have the best edge support, so you should be cautious about sleeping all the way on the very edge.

Finally, the Puffy Lux has a leg up on most memory foam mattresses because of its top layer of gel memory foam. Playfully called Cooling Cloud Foam, its gel microbeads tend to trap less heat than other types of memory foam, making it ideal for hot sleepers.

Puffy Lux Side Sleeping
Side sleeping is great on the Puffy Lux


Clocking in at a 7 on the firmness scale, the Casper is less soft than the Puffy Lux. It’s just a bit firmer than the industry standard for medium firmness of 6.5.

Rather than hug and contour, the combination of memory foam and poly foam creates more of an “on top” of the bed feel on the Casper. This should make it the more comfortable mattress for back and combo sleepers, especially anyone who experiences back pain

Stomach sleepers are a different story. While the mattress is firm enough to support occasional stomach sleeping, those who sleep strictly on their stomach might want to seek out a firmer option that lifts the hips in completely neutral alignment with their shoulders. The mattress also has a high level of edge support

Even if Puffy Lux might appeal slightly more to hot sleepers, the Casper still sleeps cool due to its top layer of aerated foam and a grid composed of bouncy, cooling material throughout.

Comparing Puffy and Casper Mattress Materials

Let’s go through each bed layer by layer to see how they’re constructed.

Puffy Lux

The Puffy Lux is Puffy’s all-foam luxury mattress.

  • CoverThe Puffy Lux cover is made of a thin polyester blend. Although fairly basic in terms of design and comfort, it is stain-resistant and easily removable to wash.
  • Comfort Layer – Beneath the cover is a two-inch comfort layer of gel memory foam, colloquially referred to by Puffy as Cooling Cloud Foam. Per the name, the foam contains gel microbeads that trap less heat than other types of memory foam. Not only do they help keep the mattress cool—they respond slowly to pressure, allowing the sleeper to sink into the mattress. This is the same comfort layer found in the original Puffy mattress.
  • Contour Layer – This is where the plush luxury element comes in. Unlike the original Puffy mattress, the Puffy Lux has an additional two inches of memory foam that makes for greater contouring, hug, and pressure relief
  • Transition Layer – Next is a two-inch layer of poly foam. Firmer than the memory foam, the transition layer is meant to provide support as you sink further into the mattress. It’s also more resistant to pressure, designed to cradle sleepers and keep them from sinking into the mattress too far down into the bed. 
  • Support Layer – Finally, the Puffy Lux has a six-inch base layer of high-density poly foam. Firmer than everything above it, the base layer supports the other foam layers, gives the mattress its shape, and—most importantly—provides sturdy support to the sleeper.

  • Cover – Made of a knit polyester blend, the Casper mattress‘ cover has a soft and stretchy feel to it for comfort and durability.
  • Comfort Layer – Next comes a layer of perforated Airscape foam. The perforations permit healthy airflow in the mattress throughout the night, which helps the bed sleep cool. The foam itself has a slow responsiveness to pressure, so sleepers can sink ever so slightly for pressure relief at the shoulders and hips. You should be able roll around and change positions fairly easily. 
  • Transition Layer – The transition layer on the Casper mattress is a little bit more complex than the foam layers above it. Its memory foam provides zoned support, which essentially means that the foam has been divided up into three sections, all with a different level of firmness. For example, soft foam at the shoulders gives a small amount of pressure relief while firmer foam at the hips gives a slight lift. The balanced texture works toward a healthy, neutral spinal alignment. The Airscape foam above prevents the transition layer from succumbing to the usual memory foam drawbacks of heat and slow mobility.
  • Support Layer – Last but not least, the base of the Casper mattress is made of a thick layer of high-density poly foam for added structure and stability.

Puffy Lux vs Casper: Best Qualities

We’re getting down to the wire. So which mattress should you choose? Since these mattresses are so different, it really comes down to your budget and what kind of sleeper you are.

Puffy Lux Best Features

  • If you’re a side sleeper, the hug and medium softness of the Puffy Lux mattress will likely give you the support and contouring you need.
  • Some people simply prefer a softer mattress that they can sink into. If this applies to you, then the Puffy Lux might make more sense than the Casper. There’s no denying the plushness of that extra contouring layer. 
  • We’ve discussed how both the Puffy Lux and the Casper mattress sleep cool. But if temperature is a high priority for you, the Puffy Lux might be worth it for the gel microbeads of the Cooling Cloud Foam. 

Casper Best Features

  • If you’re a back sleeper or combo sleeper, the medium firmness of the Casper mattress should provide the support for your sleeping position
  • Thanks to the zoned support of the transition layer, the Casper is more targeted in its pressure relief
  • It’s worth noting how much less expensive the Casper mattress is when compared to the Puffy Lux mattress. If price is a significant factor for you, then the Casper might be the way to go.

Comparing Puffy and Casper Customer Service

Now we’ll give each mattress’s customer service team a score of Stellar, Great, Satisfactory, or Poor based on our own experience interacting with each team.

Puffy Sleepopolis Customer Service Rating

Satisfactory: If you have a question, Puffy has a toll-free number you can call, as well as an emailed response form, although both involve a little bit of a wait (email can take up to 72 hours for a response). Although I was able to get an answer to my question, it would have been nice to have some kind of live or automated service for a quicker response.

Casper Sleepopolis Customer Service Rating 

Great: I gave Casper a Great score because there was an automated response on their website that was able to answer the question I had. Speaking to a live agent on the phone took a little more time (no longer than 15 minutes), but I was more than satisfied with the comprehensive answers from the automated response. 

Comparing Other Models from Casper and Puffy

Puffy and Casper both have other mattress models to choose from. Read below for more info on these beds.

Puffy Lux Mattress vs Puffy Mattress 

  • As the original Puffy mattress, this model is similar to the Puffy Lux, but without the contour layer of extra memory foam. This gives it a medium-firm score of 6.5, which might make it more appealing to side sleepers and back sleepers
  • The original Puffy doesn’t sleep as cool as the Puffy Lux, since it doesn’t have quite as much cooling technology. If you’re a hot sleeper, I’d recommend the Puffy Lux.
  • The Puffy Lux absorbs motion better than the original Puffy, which doesn’t come as a surprise because it has added layers of movement absorbing memory foam. This makes the Lux a better choice for couples, who are less likely to be disturbed by their partner on this mattress.

Casper Mattress vs Casper Wave Hybrid Mattress

  • Unlike the all-foam original Casper, the Casper Wave Hybrid combines three layers of various foams with multiple layers of springy, pocketed coils. 
  • The addition of the springs makes the Casper Wave Hybrid a good fit for heavier people in need of extra lumbar support.
  • The Casper Wave Hybrid sleeps a bit cooler than the original Casper, since its pocketed coils offer some added airflow through the mattress.
