Firmness and Feel Differences

The commonalities and differences between the Casper and Puffy have a big impact on these beds’ firmness and feel. Let’s take a closer look at what it’s like to sleep on each mattress.

How Firm Are the Casper and Puffy Mattresses?

We ranked both the Casper and Puffy around a 7/10 on the firmness scale. The industry standard for medium firmness is 6.5, so both beds are a touch firmer than medium-firm.

It’s important to note that a person’s weight and size impacts their perception of a bed’s firmness. Different people might rank these mattresses’ firmness levels a bit differently.

Sleeping on the Casper and Puffy Mattresses

We slept on the Casper and Puffy mattresses to see how they feel for us in different positions.


We felt fantastic while back sleeping on the Casper. The bed allowed our hips to sink in, so it gave pressure relief without sacrificing spinal support. In particular, we felt great lumbar support when we were back sleeping on the Casper.

While side sleeping on the Casper, we just felt okay. We didn’t feel a ton of pressure relief, so this position might become uncomfortable for someone who spends all night on their side. That said, lighter-weight side sleepers will probably enjoy better pressure relief on the Casper mattress.

Casper Mattress - Side Sleeping

Moving to our stomach, we felt decent support from the Casper’s support layer. However, strict stomach sleepers might want to look for a firmer mattress with even more overall support.


We felt a balance of comfort and support while back sleeping on the Puffy. This is ideal for back sleepers, especially folks who don’t require a significant amount of lumbar support.

While side sleeping on the Puffy, we did feel some pressure around the shoulder and hip. That said, lighter-weight people should enjoy better pressure relief while side sleeping on the Puffy.

Puffy Mattress - Side Sleeping

The Puffy felt a bit too soft for stomach sleeping. Our hips bowed into the mattress, throwing the spine out of alignment. Strict stomach sleepers will want to look for a firmer, more supportive mattress.

What Do the Casper and Purple Mattresses Feel Like?

The Casper has a bouncy, responsive foam feel. During our bounce tests, the ball bounced up pretty high. This means it should be easy to move around on the Casper mattress without feeling stuck.

The Puffy has a balanced foam feel with a classic memory foam feel on top. The memory foam makes the Puffy a bit slower-moving than the Casper, but it’s not hard to move around on this mattress.

Average Weight Sleepers – 130 lb – 230 lb

The Casper should be a nice fit for average weight back sleepers because it offers a blend of comfort and support (especially lumbar support). Average weight side sleepers might feel more pressure than they’d like when lying on the Casper. It offers decent support for stomach sleepers, although people who spend all night in this position might want a firmer mattress.

The Puffy offers decent support for back sleepers, although there’s better lumbar support on the Casper mattress. Folks who are on the lighter end of the weight range (closer to 130 lb) could enjoy decent pressure relief while side sleeping on the Puffy. This is thanks to the memory foam on top. The Puffy isn’t supportive enough for average weight stomach sleepers, and they could feel their hips bowing into the mattress.

Heavyweight Sleepers – Over 230 lb

The Casper could be a good fit for heavyweight back sleepers who are close to 230 pounds because it offers nice lumbar support. Much heavier people will need a more supportive mattress (such as one with a coil construction). It’s not a great match for heavyweight side sleepers, who are likely to feel too much pressure around the shoulder and hip. The Casper could support heavyweight stomach sleepers who are close to 230 pounds, but it might not be supportive enough for heavier folks.

The Puffy might provide enough support to heavyweight back sleepers, but much heavier people will want to look for a more supportive mattress with coils. As with the Casper, the Puffy probably won’t offer enough pressure relief to heavyweight side sleepers. It’s also not a great fit for heavyweight stomach sleepers, who will likely find the Puffy too soft to offer adequate support in this position.

Lightweight Sleepers – Under 130 lb

The Casper mattress offers excellent lumbar support that should appeal to lightweight back sleepers. Even though the Casper is designed to be softer around the shoulders, lighter-weight side sleepers might not feel enough pressure relief. The Casper mattress should be supportive enough for lightweight stomach sleepers to enjoy healthy spinal alignment.

The Puffy offers decent support and comfort for lightweight back sleepers (although it won’t offer as much concentrated lumbar support as the Casper). The soft memory foam on top of the Puffy should let lightweight side sleepers enjoy decent pressure relief. The Puffy should be supportive enough for lightweight stomach sleepers to feel like their hips remain elevated and aligned with the spine.

Mattress Construction Differences

Let’s take a deeper dive into the Casper and Puffy. We’ll look closely at the materials in each mattress and assess how these materials might impact the beds’ overall feel and performance.


The Casper’s cover is made of recycled bottles and is very breathable, allowing for airflow. The Puffy features a thin, stretchy cover that’s also breathable.

Comfort Layers

The Casper’s top layer is made of Airscape foam, a plush, responsive, and breathable foam. Underneath the Airscape foam is the Casper’s main feature, the Zoned Support system. This is a foam layer that’s firmer near the center and softer near the head and foot of the mattress. The firmer section supports spinal alignment while back sleeping and stomach sleeping, and the softer sections create more pressure relief around the shoulders.

Casper Mattress - Construction And Foam Layers

The Puffy’s primary comfort layer is made from Cooling Cloud memory foam, which has a slower-moving feel and is gel-infused to help with cooling. Below the Cooling Cloud layer, there’s a Climate Comfort layer that is firmer and more responsive. This adds some bounce to the mattress and also helps regulate temperature.

Support Layer

The Casper’s support layer features a sturdy base poly foam that gives structure and support to the entire mattress.

The Puffy’s Firm Core Support base layer is a firm-set foam layer that is unique to the Puffy. It’s firmer and more supportive than a lot of foam base layers, adding durability and structure to the mattress.

Mattress Height

The Casper is 11″ tall, while the Puffy is just a touch shorter at 10″ thick.

Casper vs Puffy Performance Differences

We put the Casper and Puffy through a range of tests to see how they perform with regard to cooling, motion transfer, edge support, and more. Let’s see how these beds stack up.

Sleeping Hot Or Cold

Both mattresses are all-foam beds with cooling components, so we called this a tie. The Casper features a breathable AirScape foam to promote airflow throughout the mattress, while the Puffy’s gel infusion helps prevent overheating.

Motion Transfer

This is a pretty close call, but we’re giving the win to the Puffy. Its memory foam layer does a nice job of absorbing motion and preventing motion transfer across the bed. Because the Casper has a bouncier feel, it didn’t perform quite as well.

Puffy Mattress - Motion Transfer

Edge Support

The win goes to Casper. Its Zoned Support system and firm base layer create a sturdier feel when sitting or standing near the edge.


The Casper and Puffy are both all-foam beds that should last for a similar amount of time (approximately 7 years).


Another tie! We found that the mattresses seemed to off-gas the same amount. Smells should dissipate within a couple of days.


The Casper and Puffy are pretty even here. Neither mattress made a significant amount of noise.


A mattress for sex should be responsive enough that nobody feels stuck in the bed. It’s also ideal if the mattress doesn’t make a ton of noise. Both the Casper and Puffy meet these criteria. Couples shouldn’t feel stuck in either mattress, and they won’t have to worry about squeaky springs on either bed.

Warranty Info

The Casper comes with a 10-year warranty and a 100-night sleep trial. The Puffy comes with a lifetime warranty and a 101-night sleep trial.
