Who is this Casper Sleep Original Foam Mattress recommended for?

Before we begin, I would like to quickly point out which kind of people will benefit most from Casper Sleep Original Foam Mattress as well as who should look for different types of mattresses.

Recommended for

This mattress is really great for the following types of people.


Back Sleepers

Back sleepers will find the Casper Sleep Original to be very comfortable due to its all-foam construction. The tri-layer design features a zoned layer which is firmer in the middle (where your back will be) yet softer at the top (where your shoulders will be). This helps back sleepers get a comfortable sleep.

Lightweight Sleepers

Lightweight sleepers will have no issues using this mattress. Its medium firm build is bouncy and responsive due to the softer top layer. It supports light sleepers in all kinds of positions without making them uncomfortable.


People who sleep in different poses throughout the night will find this mattress a comfortable fit for their needs.

People with Back and/or Shoulder Pain

The zoned layer with a firm middle and soft edges provides enough support for the back to remain in a neutral position. The softer edges let the shoulders sink and provide pressure relief. This helps relieve pain in these areas.

Here is a review from TM from Amazon. Quoting them directly, here is what they said.

“OMG…like seriously OMG…the first night and every night afterwards, my sleep has been deeper and better than ever. My husbands back pain is poof!”

Robert Strecker from Amazon says the following:

“wow this is impressive and ideal for people with spine as well as shoulder issues”

As they go on to describe their injured shoulder issues and how this mattress helped them.

Not Recommended for

The Casper Sleep Original Mattress is not recommended for the following types of sleepers.

Strictly Stomach Sleepers

People who only sleep on their stomachs will become uncomfortable because their core will sink into the bed. This disturbs the sleeping posture and results in discomfort.

Heavy Sleepers

Heavy sleepers (250 pounds+) will not get the desired support from this all-foam mattress. They should look into firmer beds to support their weight.

Strictly Side Sleepers

People who only sleep on their sides will not like this mattress as it cannot provide sustained support for their shoulders and hips.

Let our Mattress Reviews be your guide to finding a mattress that feels like it was made just for you.

How is the Casper Sleep Original Mattress Designed/Constructed?

Casper Sleep Original Foam Mattress Review

The Casper Sleep Original is an 11 inches tall, all-foam mattress that is made of three layers of memory foam. The first layer is made of a proprietary foam called AirScape and is a product of Casper. This serves as the comfort layer and is quite soft, therefore it contours around the body quite snugly.

The second layer is made of a zoned memory foam. This layer has differing softness/firmness in different parts, hence being called zoned. Put simply, the top and bottom of the layer where the shoulders and feet lay are soft, while the middle where the back lies is firm. The firm middle portion is great for providing lumbar support for back sleepers.

The third layer is called the support layer and it is much firmer than the comfort layers. This provides support for the sleeper and prevents them from sinking into the mattress.

What are the Features of Casper Sleep Original Mattress?

In this section, we will do a deep dive into the features of the Casper Sleep Original Mattress. We will take a look at how its construction translates into the mattress’ features.

Motion Isolation/Transfer

As an all-foam mattress, the Casper Sleep Original is quite good at motion isolation. Its top layer is bouncy and soft so it is great at absorbing motion rather than transferring it. This is further improved by the presence of the second, zoned comfort layer. 

My own testing as well as reviews corroborate this fact. If you want a better idea, then consider this.

  • Small movements such as tossing and turning cannot be felt.
  • Medium movements such as sitting up or sitting down on the bed are barely felt.
  • Large movements such as jumping or throwing things are felt, but not to a disturbing extent.

As such, sleepers who get disturbed by their pet’s or partner’s movements should benefit a lot from the Casper Sleep Original mattress.

This short and sweet review by Rosemary really tells you a lot about this feature.

“For the price a great mattress. It is firm which I like. I don’t feel my partner getting up and down all night. Would buy again. Recommend to my brother.”

Pressure Relief

One of the most attractive features of a mattress is pressure relief. Thanks to the triple-layer construction and a zoned comfort layer, the Casper Sleep Original is great at providing pressure relief. 

In ideal cases, customers such as you want to have a soft layer underneath the shoulders so that they don’t feel pressure and can relax. But they also want a firmer surface underneath their pelvis to provide spine support. With the zoned comfort layer that is possible and as such provides relief to both the shoulders and the back/hips at once. 

Reviews also corroborate this fact as you can see below.

Joe O, an Amazon customer had this to say in their five-star review.

“It comes with Casper’s Signature ProSupport that prevents you from sinking into the mattress and the Premium memory foam conforms to your body to absorb pressure.

I’m getting such a great sleep with this mattress and wake up so refreshed every morning.”


Carol C, another Amazon customer had this to say:

“I’ve been sleeping well on this mattress for over three years now — It is as comfortable and supportive as the day I unrolled it. The mattress isn’t overly plush, but it is a sweet spot of soft and supportive

Edge Support

All mattresses do not usually have great edge support. That’s due to the absence of reinforced edges. However, the Casper Sleep Original does not have this as bad as others due to the firm support layer.

So, if you sit at the edge of the mattress, you will feel some sinking, but you will never sink right to the edge of the bed frame (provided you are not too heavy). Sleepers who weigh more than 240 pounds will find the edge support quite lacking as the support layer is not enough to hold their weight.

If you are looking for better edge support then you look at spring mattresses or other similar options that have reinforced edges.

Temperature Regulation

The Casper Sleep Original is much better than other foam mattresses at cooling. This is thanks to the AirScape layer at the top. This layer of foam has lots of small perforations that allow trapped warm air to escape. This promotes cooling as any heat generated by the body escapes promptly.

So, hot sleepers who insist on using foam mattresses can use the Casper Sleep Original to get all the benefits of a medium-firm mattress with none of the cooling drawbacks. Amazon reviews also tend to agree that the temperature regulation of this mattress is quite good.

Here is an excerpt from an Amazon review by Victoria Moore:

“…best of all sleeps much cooler than my mattress with the foam top, something that is very important when you live in a desert.”

Testing Casper Sleep Original Foam Mattress with Different Weights and Sleeping Positions

This mattress is primarily aimed at lightweight and average-weight people. Heavier people will not find this mattress to be as comfortable because all-foam construction is not firm enough to bear their weight. 

With that said, we have still tested this mattress with all weight classes in all three sleeping positions. The results should help you make a better decision when you are looking to make a purchase.

Light Weight Sleepers in all three positions

So, first of all, light weight sleepers are people who weigh less than 130 pounds (app. 59 kg). Light sleepers require a soft mattress so that it can contour to their body shape. Soft mattresses work for light sleepers because such people do not sink into them. The top AirScape comfort layer helps provide that bouncy and soft feel that lightweight people require. So they can sleep well in all positions. Here’s the breakdown of all positions.

Light Weight Side Sleepers

Lightweight side sleepers will have no problems at all. Their shoulders will and midsection will sink into the mattress just enough that their spine is in a neutral position. That way they will have no sore backs or aching shoulders when they wake up.

Light Weight Back Sleepers

Lightweight back sleepers will find that this mattress is great for them. The zoned support layer will provide lumbar support and assist in spinal alignment. The very same zoned support layer will also ensure that the shoulders are pressure-free.

Light Weight Stomach Sleepers

Lightweight stomach sleepers will have no issues sleeping for extended periods of time on their stomach. The zoned support layer that is firmer under the hips will ensure that the midsection does not sink too much into the mattress.

Explore the detailed insights provided in the Casper Sleep Snow Mattress Review 2023 for a thorough understanding of this mattress.

Average Weight Sleepers in all three positions

Average-weight sleepers will also have no trouble using the Casper Sleep Original. Average weight here refers to people in the weight range of 130 pounds (59 kg) to 230 pounds (104 kg). These people will find this mattress comfortable in all three positions as well.

Average Weight Side Sleepers

Side sleeping requires that the shoulders and midsection sink into the mattress moderately so that the spine remains neutral. The Casper Sleep Original facilitates this through the use of its comfort layer which is relatively softer than the support layer.

This greatly benefits people with neck and shoulder pains because of the great position and pressure relief.

Average Weight Back Sleepers

If the Casper Sleep Original had a really specific target market, it would be these people. Average-weight back sleepers will find the Casper Sleep Original to provide the utmost comfort. The mattress will contour to their body shape without letting them fall into the mattress. The zoned layer of the mattress offers excellent lumbar support, while the softer sections provide relief to the shoulders.

Average Weight Stomach Sleepers

Average-weight stomach sleepers will have some issues depending on their weight. The closer they are to the upper limit, the less time they can spend in this position. So, strict side sleepers should take note before buying this mattress. Combination sleepers on the other hand will have no issues.

Delve into the comprehensive insights provided in the Casper Mattress Review for a detailed understanding of this product.

Heavy Weight Sleepers in all three positions

This mattress is not really good for people who weigh more than 230 pounds. The top two layers of the mattress are too soft to support such weight. So, heavy sleepers will sink right into the support layer. But it’s not all doom and gloom as you will see in the following sections.

Heavy Weight Side Sleepers

Heavy-weight side sleepers are not going to like this mattress. Their shoulders will sink too deep into the mattress and throw their spine out of alignment. An extended amount of rest in that position will result in sore shoulders, an aching neck, and a sore back.

Heavy Weight Back Sleepers

Heavy-weight back sleepers can actually have a really comfortable rest on the Casper Sleep Original mattress. But this is only true if the weight is close to 230 pounds. For people much heavier than this, they will sink right to the bottom of the mattress.

Heavy Weight Stomach Sleepers

Unfortunately, since even average-weight stomach sleepers cannot enjoy an extended rest on this mattress, neither can heavy-weight sleepers. There just is not enough support. 

And that is understandable since this mattress is not for heavy people. This is primarily aimed at average and light-weight sleepers.

Ease of Use and Customer Service/Support of the Casper Sleep Original Foam Mattress

How easy is it to Unbox and off gas

The Casper Sleep Original is a typical mattress-in-a-box product. So, it comes wrapped in two layers of plastic and packed in a box. To unpack it, you only need to open the box, move the mattress to the room where it will be used, and cut the plastic layers.

The mattress will start to expand quickly but it is recommended that you give it 24 hours to expand fully. As for off-gassing, a chemical smell will be released upon unpacking, but if you put the mattress in a ventilated space, it will clear out within a day or two.

This review from Amazon customer “Brabs” provides some info about this.

“Love it! We replaced an old mattress in our motorhome. Super comfy, no odor, quick delivery, fast easy set up. We’re sleeping like babies and waking with lots fewer aches and pains!!!”
