If you’ve browsed through beds online, you’ve likely stumbled upon the Casper. Launched in 2014, Casper became one of the most popular mattress brands on the market and offers a vast array of different mattresses. In this review, our team is looking specifically at the all-foam Casper original mattress.

Curious to know what this bed’s made of, how it feels, and who it could be best for? Then keep on reading for my full review of the original Casper mattress. Or, skip down to my review summary for an overview.

Is the Casper Original a Good Mattress for You?

Before I go into all the details, let’s answer the most important question: will it suit your needs? This medium-firm mattress has a gentle all-foam feel that works particularly well for certain types of sleepers.

Who I Recommend the Casper Mattress for

• I think this mattress could be a great fit for back sleepers. Not only is it easy to move around and change positions, but the bed does a great job of positioning the spine in a nice, even line.
• The Casper has a softer feel at the shoulders, making it an awesome option for those trying to avoid shoulder pain.
• This mattress could be a good fit for folks who are struggling with back pain as it strikes a satisfying balance between pressure relief and support.

Who I Don’t Recommend the Casper Mattress for

• This all-foam bed doesn’t suit heavy people in need of firmer support. I’d recommend they check out one of our best innerspring mattresses to find a more supportive option.
• Similarly, some strict stomach sleepers might find this bed a bit too soft. I’d recommend one of our best hybrid mattresses instead.
• The Casper mattress doesn’t feature much body-contouring. If you’re looking for sinkage, one of our best memory foam mattresses might be a better fit.

How Firm is the Casper Mattress?

Now that we’ve got a solid overview of the Casper mattress, let’s talk about how it feels, starting with firmness.

Like any feel factor, firmness is quite subjective, and changes depending on one’s body type and preferred sleeping positions. Therefore, my read of this bed’s firmness could differ from your own.

When I first pushed into the Casper and sat on it, I thought it felt pretty soft. However, after laying down and rolling around on the bed, it felt firmer to me as it lifted me up and offered me support. Because of this, I decided to give the Casper a 7 out of 10 on the mattress firmness scale. When compared to the industry standard of 6.5 for medium firmness, this bed is slightly firm.

The mattress got a 7 from me because I think it has a firm, supportive feel. Though the foam materials are soft to the touch and provide nice relief at the shoulders and hips, the overall design works to lift the sleeper up and out of the structure. This creates more of an “on top” of the bed feel, which could work great for back and combination sleepers.

It’s worth mentioning the Casper is zoned for support. So, it uses firmer foams at the lower back for extra lift, and softer foams at the shoulders for extra cushion around pressure points. This combo is nice for sleepers suffering from lower back or shoulder pain, since it helps keep the spine in a healthy alignment without creating stiffness in the shoulder area.

Casper Mattress Performance

While firmness can tell us a lot about how a bed feels, it’s far from the only thing to consider when shopping for a new mattress. So, I tested this bad boy for factors like pain relief, support in different sleeping positions, and more.

Testing the Casper Mattress in Different Sleeping Positions

Everyone has different mattress needs depending on their preferred sleeping position and body weight. Take a look below to see if the Casper could work for yours.

Is the Casper Mattress Good for Light Sleepers (Under 130 pounds)?

• Light Back Sleepers – Light back sleepers should feel great on the Casper. Its zoned support system should keep their spines in a nice even alignment.
• Light Side Sleepers – Light side sleepers might find the Casper a bit too firm. They may not sink through its foams enough to get the necessary pressure relief.
• Light Stomach Sleepers – The Casper should work well for light stomach sleepers. It’s firm enough to keep their hips lifted up in line with their shoulders.

Is the Casper Mattress Good for Average Weight Sleepers (130 – 250 pounds)?

• Average Weight Back Sleepers – The Casper should feel fantastic to these sleepers. I sank through the top layer of aerated foam and felt the materials lifting up my hips and filling in the space at my lumbar region.
• Average Weight Side Sleepers – Average weight side sleepers should like the Casper, especially if they alternate between their side and another position at night. The softer foams at the shoulders should allow nice, pressure-relieving sinkage.
• Average Weight Stomach Sleepers – These sleepers will find their hips sinking into the mattress too far, creating a bend in their spines. That can lead to pain over time. So, average weight stomach sleepers should opt for a firmer bed (if that’s their sole sleeping position).

Is the Casper Mattress Good for Heavy Sleepers (over 250 pounds)?

• Heavy Back Sleepers – Heavy back sleepers might want something with firmer innerspring coil support. I’d recommend they opt for one of our best mattresses for heavy people.
• Heavy Side Sleepers – Heavy side sleepers might like the Casper, as its zoned support could offer the right balance of sinkage and support for them. If you think you’ll need extra support, you might want to stick to a hybrid mattress.
• Heavy Stomach Sleepers – The Casper is too soft for heavy stomach sleepers, and will let their hips sink into the bed too far. This can throw their spines out of alignment and lead to back pain.

Casper Mattress Pain Relief Performance

Pressure relief refers to a bed’s ability to alleviate tension at the shoulders, hips, and lower back. This is an important measure for all sleepers, but especially those struggling with pain at night. To demonstrate the Casper’s pressure relief, I’ll be testing it out with a pressure map.

It works like this: I roll out the device, hop aboard, and let the map do the rest. As I roll around, the map records how much force I’m exerting on the mattress, creating a colored “map” of the pressure. For reference, blue/green indicates areas of low pressure and orange/red indicates areas of high pressure. The results below will help me determine if the Casper is a good choice for relieving pain.

Back Pain — These results (especially when I’m lying on my back) tell me the Casper would be great for relieving pain, especially at the lower back. The zoned support foams offer extra support, keeping your hips boosted up in line with your shoulders. This is key to avoiding back pain. For this reason, the Casper is featured in our best mattress for back pain roundup. However, stomach sleepers will likely want a firmer mattress to help alleviate back pain.

Shoulder Pain — The Casper should relieve shoulder pain for back and stomach sleepers. Side sleepers with shoulder pain might want to opt for a mattress with an additional layer of memory foam to get even more cushioning.

Hip Pain — The Casper may not be the best choice for back sleepers with hip pain. The firm foams at the hips are great for back support, but not ideal for extra hip pressure relief.

Casper Mattress Performance for Couples

Couples need a mattress that combines motion isolation, mobility, cooling properties, and edge support. Read on to learn more about why, and to find out how the Casper performs in those areas.

Motion Transfer

Motion transfer refers to the amount of movement detectable from one side of the bed to the other. All sleepers will want to pay attention to this feel factor, though it’s most relevant for those who share their bed with a partner and don’t want to feel disturbed at night.

To illustrate motion transfer, I dropped a 10-pound steel ball from heights of four inches, eight inches, and 12 inches and measured the disturbance it caused. The bigger the lines, the bigger the disturbance.

These motion transfer results tell me that the Casper does a decent job of isolating motion across the structure. While you’re still likely to feel your bed mate moving around, it shouldn’t be so major as to seriously disrupt your slumber.

Sex

Generally, the best mattress for sex is fairly responsive, so it’s easy to move around and change positions on it. So, the Casper should be a nice option for couples looking for a bed that is easy to move around on during sex. Its combination of motion isolation and mobility should hit a sweet spot for many couples.

Cooling

You’re much more likely to overheat when you’re sharing a bed with a partner, so a cooling mattress is paramount. The Casper sleeps cool for a foam mattress thanks to layers of open-cell Airscape foam that encourage breathability. Most couples and hot sleepers should feel comfortable on this bed. However, for more options, check out our favorite cooling mattresses.

Edge Support

Edge support is a measure of whether or not you can sleep on the side of a bed without it collapsing under your weight. Strong edges make a bed feel larger, which is important for couples who want to maximize the surface area of their mattress. The Casper has good edge support; I felt stable sitting and lying on the edge of this mattress.

What is the Casper Mattress Made Of?

The Casper mattress is built with three layers of foam, including a top layer of breathable aerated foam, a middle section of zoned support, and a sturdy bottom layer of high-density poly foam.

This combination of materials is intended to produce a balanced, medium-firm feel. To see if the brand pulls this off, let’s take a peek under the cover.

Cover — Made of a knit polyester blend, the Casper’s mattress cover has a soft and stretchy feel.

Comfort Layer — Things truly kick off with this top layer of Casper’s Airscape foam. This material has a slow response to pressure, allowing the sleeper to sink in for pressure relief at the shoulders and hips. Though this kind of contouring would usually produce overheating, small aerations along the material’s surface increase breathability to promote airflow and release trapped body heat.

Transition Layer — Up next, you’ll land on a memory foam layer of zoned support. This section has been divided into three different zones, all of which feature slightly different firmnesses. There’s softer foam at the shoulders for a bit of pressure relief and firmer foam at the hips for a little lift. This creates a nice, balanced vibe that works to position the spine in a healthy, neutral alignment.

Base Layer — A thick layer of high-density poly foam, which provides shape and stability to the structure, rounds things out.

Casper Mattress Unboxing and Off-Gassing

Like most bed-in-a-box mattresses, the Casper does release a bit of a chemical smell once it’s opened. This odor should dissipate within 24 to 48 hours, and is no stronger than the smell of a typical box mattress. Unboxing the Casper is easy. This bed isn’t overly heavy or difficult to remove from its box.

My Final Thoughts About the Casper Mattress

Now that we’ve tested the Casper mattress, it’s time to go over who would get a great night of sleep on it, and who might need to take a look at some other options.

My Favorite Things About the Casper mattress

This all-foam mattress is a great option for back sleepers who want a balance of support and pressure relief, as well as combination sleepers, who should easily change positions throughout the night. My favorite feature of this bed is its zoned support system, which really promotes healthy sleep posture. I’d highly recommend this bed to anyone with back pain.

I appreciate that the Casper sleeps cool and suits hot sleepers. This cooling might be a nice perk for couples, who tend to overheat in bed more quickly than solo sleepers.

My Casper Mattress Complaints

I wouldn’t recommend the Casper to strict side or stomach sleepers. It’s medium-firm feel is great for a lot of people, but it’s not firm enough for strict stomach sleepers. Nor is it plush enough for strict side sleepers, who need a lot of cushion. Other than that, I don’t have many complaints about the Casper. If it works for your sleeping preferences, it should be a great replacement for your old mattress.

Casper Mattress Vs

After giving the Casper a thorough once-over, I thought it might be beneficial to size it up against some of its biggest competitors on the mattress market, namely the Purple and Nectar mattresses.

Casper vs Purple

• Though the Purple is also a popular bed-in-a-box mattress, it’s got a different feel from the Casper, thanks to its hyper-elastic polymer smart comfort grid.
• This grid is composed of a bouncy and cooling material, so could be great for combo sleepers who overheat at night.
• The collapsible grid is fantastic at alleviating tension across the body, especially at the hips, shoulders, and lower back.
• Read my full Purple mattress review to learn more. Or check out our Casper vs Purple mattress comparison.

Casper vs Nectar

• Like the Casper, the Nectar is an all-foam bed, but it’s built almost entirely of memory foam.
• This gives the mattress a super plush feel with plenty of sinkage, body-contouring, and pressure relief.
• I recommend the Nectar for strict side sleepers who are likely to enjoy the bed’s thick top layers of memory foam.
• For more, read the full Nectar mattress review. Or check out my Casper vs Nectar mattress comparison.

Casper Policies and FAQs

Does Casper offer a mattress warranty?

Yes! All Casper mattresses come with a 10-year limited warranty.

How does the Casper mattress ship?

All Casper mattresses ship for free. They’ll arrived compressed in a box, so will need a few hours for off-gassing and decompression after unboxing.

Does the Casper come with a sleep trial?

Yes, Casper offers a 100-night trial period with this bed. If you decide you don’t like your Casper within this period, you can return it for a full refund (minus some shipping costs).

Do I need a box spring with the Casper?

No, any hard flat surface will work to support this bed. That includes platform bed frames, adjustable bases, and box springs.

What do customers have to say about the original Casper mattress?

“From the delivery of the box to the magical unfolding of the king size mattress to the first time laying on the bed, all smiles here!” – Paul

“Pretty comfy but lacking some edge structure and way too soft if you add a topper.” -Kim

“Being used to sleeping on a firm mattress, switching to Casper had an initial adjustment period…but later it really helped with shoulder pain for side sleeping and gives good back support.” -Ravi Teja

Other Models from Casper

The Casper mattress doesn’t just face competition from other brands. It also faces some stiff competition from other beds in the Casper line. So, let’s go over two other popular Casper beds.

Casper Original vs Casper Wave Hybrid

• Billed as Casper’s luxury model, the Wave is made up of five layers of foam and springs to create a structure that’s as pressure-relieving as it is supportive.
• This bed is a great option for sleepers who struggle with aches and pains at the shoulders and hips thanks to special gel pods in its center that promote healthy sleep posture.
• The Wave is more expensive than the original Casper, so budget shoppers might want to stick with the original bed.
• Learn more in our full Casper Wave Hybrid mattress review.

Casper Original vs Casper Nova Hybrid

• The Casper Nova Hybrid is a dynamic mattress that’s both super plush and incredibly supportive.
• Like other Casper mattresses, the Nova comes equipped with a special layer of zoned support, which works to lift the hips and cradle the shoulders for optimized spine alignment.
• Compared to the Original Casper, the Casper Nova is much softer. So, it could be especially nice for side sleepers or those who prefer a cuddly sink.
