And The Winner Is…

While these two mattress brands sound like something out of a children’s ghost story, they’re actually two of the most famous mattress manufacturers in the industry (both of which have excellent customer reviews).

The Puffy is one of the newest brands to come out with their own variation of foam that’s been designed to put memory foam brands out of business with the performance it provides. It’s a super cool, super advanced mattress that represents the cutting edge of modern-day mattress materials technology.

The Casper, on the other hand, sticks to more standard materials (that are still reasonably advanced) and instead uses clever design patterns to create the performance of their product. Their complex memory foams and zoned support sections have had us mattress nerds excited about the brand since they first released their product.

Today we’re going to put the Puffy and the Casper head to head in this review. We’re going to be looking at each layer of material that they have inside of them to see which ones we like (and which ones we don’t like). We’re going to conclude by answering some common questions before giving you our opinion on which one you should buy when we announce the winner.

Let’s get started.


  • Both products sleep cool
  • Both use advanced design patterns
  • They’re more or less the same price


  • The Puffy doesn’t use memory foam
  • The Casper has a zoned support section
  • The Puffy uses cooling gel the Casper uses open cell material

Construction Comparison

We’re looking at two hybrid products today, which sounds fancy but all it actually means is that these mattresses use different layers of different materials. This is pretty standard stuff these days, and it allows brands to create advanced designs that benefit from different properties of different materials.

Casper Construction

The Casper is a 4 layer hybrid product that’s 10 inches thick. This thickness gives the mattress a sense of luxury and opulence that thinner products can sometimes struggle with.

Open Cell Memory Foam

The top layer of the Casper is made from one of the most advanced kinds of memory foam on the market called open cell memory foam. This kind of memory foam is one of the most difficult (and expensive) memory foams to create – but it is well worth the effort as it solves the overheating issues that normal memory foam is well known for.

To understand why open cell foam is good (and not just a marketing gimmick) we need to take a quick science class.

Memory foam has the contouring properties that it does because it is made up of lots of little cells of air on the microscopic level. Throughout the night body heat enters the mattress and gets inside these cells and heats the air that is trapped inside of them up. Because the cells have no gaps in their walls and are completely enclosed the hot air cannot escape, and hot spots form underneath the sleeper.

As the name suggests, open-cell memory foam opens these cells partially on one side to allow for ventilation inside the mattress. Hot air can escape the cells and go out into the bedroom reducing the overall temperature in the mattress and eliminating the hot spot issue.

It’s an obvious solution to the problem, but actually creating and designing the material is much harder than it sounds.

High-Density Memory Foam

The next layer down is made from standard memory foam (that’s closed cell). The lack of cooling technology in this layer isn’t a huge problem as it’s not in direct contact with the sleeper – although it wouldn’t have hurt for Casper to include it. This layer provides some of the support of the mattress, it also acts as a gradient between the softer top layer and the firmer section below.

Zoned Support Section

This is where things really get interesting with the Casper. This layer uses what is known as a zoned design pattern, which isn’t unique to Casper – but it’s a design type that you’ll only get from the best brands.

Normal mattresses have the same kind of material across the entire length of the mattress in each layer. Zoned mattress, however, use different materials in different parts of the product to give you various properties across the sleeping surface.

In this section Casper have done this by splitting the layer into two parts, one section towards the top has a slightly firmer foam, and the other section towards the bottom has a slightly softer foam.

This configuration has been specifically designed for side sleepers and allows your hips to sink in and get more support (as that’s where the most pressure is) and it also allows your shoulders to sit a little higher. This promotes proper spinal alignment and mitigates some of the joint issues that side sleeping can cause

High-Density Support Foam

As usual, the base of this mattress is boring and uninteresting. It’s made from a normal high-density support foam that gives some stability and security to the layers above. It’s a high-quality foam that’s not going to degrade and it does its uninspiring yet essential job well.

Pros And Cons


  • Zoned support section
  • Open cell memory foam
  • Reputable brand
  • Very supportive
  • Great for side sleepers
  • Comfortable luxurious feel


  • Could benefit from cooling tech in second memory foam layer (if we were being fussy)

Puffy Construction

The Casper above is a reasonably advanced mattress in terms of both design and materials technology (compared to other products in this price bracket). However, the Puffy makes it look like it’s from the stone age. There are only two layers in the Puffy, which is unusual for a hybrid mattress, but as you’re about to learn – there’s no need for a third material here.

Comfort Cloud

Comfort Cloud is one of the most advanced materials that a mattress manufacturer has ever created. It’s a proprietary material that took Puffy over 4 years to create. It was designed to improve upon memory foam in every possible way, and they very nearly succeeded.

The only shortcoming of Comfort Cloud compared to memory foam is in terms of contouring. Like memory foam, Comfort Cloud will contour to your body and shape itself based on the pressure that is applied to the material. While it does a very good job of this, memory foam is still slightly better. The difference in performance is small, but it’s noticeable.

However, the benefits of Comfort Cloud massively outweigh this very slight difference in contouring.

Comfort Cloud doesn’t use the cell-based design of memory foam that we talked about in the Casper section above. As such there’s no place for hot air to get trapped in the mattress and create hotspots. Comfort Cloud was specifically designed to disperse heat and be extremely good at natural ventilation – it’s one of the coolest sleeping surfaces on the planet.

Comfort Cloud on its own is already going to be cooler than the most advanced memory foams on the market, but Puffy didn’t stop there. They added a cooling gel too.

However, the combination of Comfort Cloud and a normal cooling gel would possibly make the mattress a bit too cool to be considered comfortable. Due to this, they had to create their own kind of special cooling gel (called Cooling Cloud) that aims to achieve an optimum temperature instead of going for full cooling.

The other main benefit that Comfort Cloud has over memory foam is the speed at which it contours to your body.

If you’ve slept on a memory foam mattress before you probably already know that it takes some time for the contouring to fully take effect. This delay is because body heat needs to enter the mattress and weaken the walls of the cells inside the material to allow them to collapse fully.

As Comfort Cloud doesn’t use a cell-based design like memory foam, it doesn’t have this delay and the contouring action is almost instant. This sounds like a little “added extra benefit” over memory foam, but it’s actually very noticeable. When you get into bed or change sleeping position throughout the night you’re going to really appreciate it.

High-Density Support Foam

Again the bottom layer of this product is a standard high-density foam. It does exactly the same job as the bottom layer in the Casper, it’s made from a high-quality material, and it provides the stable base the top layer of awesomeness needs.

Pros And Cons


  • Comfort Cloud
  • Cooling Cloud
  • Super cool sleeping surface
  • Instant contouring action
  • Very comfortable
  • Highly supportive


  • Doesn’t have a zoned section like the Casper

Firmness Comparison

There’s not a lot of difference between the Puffy and the Casper in terms of firmness. They are both medium firm products that rate 6.5 out of 10 on the firmness scale.

Medium firm mattresses are by far the most popular level of firmness. Unless you’re someone that knows for a fact that they like a firm or soft product, this is going to be a firmness level you find enjoyable.

Price Comparison

There are a couple of small differences in the prices of these two products, but honestly they more or less cost the same.

Something we want to point out is that you should pay no attention to the “time-limited discount” that Puffy have on their website. It’s fake, you can clear your cookies and when you visit the site again you’ll get the discount. Worst case scenario – just visit from a different computer on a different connection when you’re ready to buy.

We’re disappointed in Puffy for resorting to such trickery and high-pressure tactics, and we wish they’d stop it – the mattress is more than good enough to sell itself without them.

Puffy Prices (With The “Time Limited” Discount Applied)

  • Twin – $595
  • Twin XL – $625
  • Full – $795
  • Queen – $950
  • King  – $1,150
  • California King – $1,150

Casper Prices

  • Twin $595
  • Twin XL $645
  • Full $895
  • Queen $995
  • King $1,195
  • California king $1,195

Which Bed Sleeps Cooler?

The Casper is an exceptionally cool memory foam product thanks to the open cell design that provides huge amounts of ventilation. We highly doubt anyone reading this would be able to complain about its thermal regulation capabilities.

But while the Casper is good, the Puffy is great…

The Puffy is one of the coolest sleeping surfaces that we’ve ever seen. It’s got excellent ventilation, Comfort Cloud is inherently good at distributing heat, and the Cooling Cloud gel is the cherry on top.

Don’t hold this against the Casper, it’s rare we find a product that can compete with the Puffy in terms of thermal regulation.

Which Bed Would Be Best For A Side Sleeper?

The Casper wins this category thanks to its zoned support section.

The Puffy is an excellent product that will be great for side sleepers – just like any other quality memory foam product – but it’s still a “one size fits all” design pattern.

By tailoring the amount of support along the sleeping surface the Casper promotes proper spinal alignment for side sleepers in a way a single zone product could only dream of.

Should I Buy A Casper Or Puffy Bed?

Quite honestly we could understand if you brought either of these products, they are both excellent and provide great value for money.

Which one you should go for really depends on what you prioritize more.

  •    If you want the coolest sleeping surface possible with instant contouring then the Puffy is your best bet.
  •    If you prefer to prioritize spinal alignment and support, then you should probably consider the Casper

Note: The Casper is still a cool sleeping surface, and the Puffy still provides excellent levels of support and optimizes spinal alignment – it’s just that these are the two main ways the products differ.


So there you have it, that’s what we think about the Puffy and the Casper.

They’re both excellent products that have been created and designed with care. Either of them is going to make you a very happy sleeper and you’re going to get years of enjoyment out of both of them.

Sweet dreams.
