Casper Mattress Video Review

How Does the Casper Mattress Feel? 


The Casper Original is a medium-firm mattress, with its firmness falling at a 6 on the 1-10 firmness scale, with 1 being the softest and 10 being the firmest. Most sleepers prefer a medium-firm feel because these beds tend to do a good job at providing both pressure relief and support, and the Casper Original does an excellent job at delivering a balanced sleeping experience that suits every sleeping position. 

The Casper Original’s comfort layer is a plush and responsive polyfoam that brings immediate comfort and light contouring that works well for back, stomach, and side sleepers. The next layer provides ergonomic support, with firmer memory foam found along the body’s lumbar region and softer foam at the shoulders and foot of the bed. What this means is that side sleepers experience excellent pressure relief while back and stomach sleepers won’t sink too far into the mattress. 

While lightweight and average-weight people are well supported on the Casper Original no matter their sleeping position, heavier folks are not as good of a fit. If you weigh more than 230 pounds, you may require more support at your hips—stomach and back sleepers—or more cushion at the shoulders—side sleepers

Does the Casper Original Sleep Hot?

The Casper Original is a memory foam mattress, and traditional memory foam beds are known to sleep hot. To reduce the risk of overheating, Casper utilizes perforated polyfoam in the top layer. Not only do the perforations mean greater airflow, but the polyfoam doesn’t retain body heat to the same degree as memory foam. This means that the Casper Original sleeps cooler than many all-foam mattresses, but it’s not as cool as the average innerspring or hybrid bed. While the Casper is cool enough for the average person, most people who often wake up hot and sweaty would be better off considering one of the beds that made our best cooling mattresses list.  


The Casper Original is supportive for an all-foam bed. Thanks to a durable foam base and stronger memory foam along the middle of the mattress—where the heavier parts of the body are—the Casper is likely to last lightweight and average-weight people around seven to ten years with plenty of support for healthy spinal alignment in every sleeping position. 

Another perk of the Casper is that it performed nearly perfectly in our test for edge support, which is how stable it feels when you lie or sit along the edges of the mattress. Whether you sit on the edge of your bed to put on your shoes or stretch out all the way to the perimeter while you’re sleeping, you should feel supported on the Casper Original mattress. This also allows couples to maximize sleeping space and allows older people to use the edges when getting into bed. See our top picks for the best mattresses for seniors.

While the Casper is plenty supportive and durable for people who weigh less than 230 pounds, it’s less so for those who weigh more. Because the Casper has no durable innerspring coil support system and a soft comfort layer, it doesn’t provide the extra support needed by bigger bodies. This means you heavyweight sleepers could face excess sagging, potential lower back pain, and poor durability

Back Sleepers

If you’re a back sleeper looking for a mattress that fills in the small of your back, keeps the hips and neck in line, and offers a decent amount of soft comfort, the Casper Original is a great choice. Though this is an all-foam mattress, the ergonomic Zoned Support foam provides firm support along the body’s core with soft foam at the shoulders, neck, and feet. 

Heavyweight back sleepers may experience more sinkage than a lightweight or average-weight back sleeper, but it shouldn’t be enough to throw the spine out of alignment. For more top mattress options, see our picks for the best mattress for back sleepers

Side Sleepers

The foam layers of the Casper Original mattress provide quality support for side sleepers who are lightweight and average-weight. The brand has constructed the mattress with Zoned Support, meaning the mattress is softer around the shoulders and more firm near the hips and lower parts of the back. This type of construction protects pressure points in the shoulders and keeps the spine and neck aligned. 

However, the firmer core foam may lead to too much pressure at the hips of heavyweight side sleepers, and the softer foam at the shoulders may sink in too far. For this reason, we recommend heavier side sleepers consider one of the beds that made our best mattresses for side sleepers roundup.   

Stomach Sleepers

The best mattresses for stomach sleepers are firm enough to keep the hips and thighs from sinking too deeply into the mattress while soft enough to deliver a touch of cushion to the front body. We wouldn’t say the Casper Original is the best mattress for strict stomach sleepers, but it’s okay for some stomach sleepers

The Casper’s soft top layer isn’t firm enough to minimize sinkage at heavier parts of the body in heavyweight stomach sleepers. Still, lightweight and average-weight stomach sleepers may enjoy the Casper because their hips won’t sink in too far. 

Combination Sleepers

Combination sleepers, who move around often throughout the night to change positions, are a good fit for the Casper mattress. Like many of the best mattresses for combination sleepers, the Casper uses a responsive foam in the top layer that makes it easy to move around. Additionally, it supports lightweight and average-weight sleepers in every sleep position, so you can sleep in whatever position you find comfortable while being properly supported. 

We do not recommend the Casper Original for heavyweight combo sleepers. There are no responsive coils, so heavier folks may find it hard to move around and get comfy. Additionally, the comfort layers are thinner than is needed for people who weigh more than 230 pounds to experience sufficient pressure relief.  

NERD RATING: Will this bed work for you? 

Lightweight (< 130 lbs):  5 4 4
Average weight (130 – 230 lbs): 5 3 5
Heavyweight (> 230 lbs):  3 2 2

1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent

Does It Fit Your Lifestyle?


We think the Casper Original is a great mattress for couples. Not only does it support sleepers in every sleeping position, which allows couples with different sleeping habits to co-sleep comfortably, but it isolates motion transfer very well. Stellar motion isolation helps couples sleep through their partner’s movements, whether that’s tossing and turning, going to the bathroom, or getting into or out of bed. 

Additionally, the Casper is an all-foam bed, which means there are no bouncy springs to make noise when someone moves. And the Casper’s edges are comfortable to lie along, so you can carve out some personal space without worrying that you’ll roll off during the night. 


The Casper mattress has a competitive price point when considering its unique perks. For instance, the Original Casper is one of few mattresses that cost around $1,000 for a queen-size bed that boasts ergonomic support. The zoned layer of memory foam provides excellent pressure relief and spinal alignment in every sleeping position, and the durability at the body’s core boosts the longevity of the Casper mattress

While the Casper Original is a good bed for budget shoppers, there are some less expensive all-foam mattresses. Check out our best cheap mattresses lineup to find other budget-friendly beds. 

Back Pain

The Casper Original is one of the best beds for lightweight and average-weight people with back pain. With a soft comfort layer that cushions the body and a Zoned Support transition layer, the Casper is designed to keep the spine properly supported in every sleeping position. Healthy spinal alignment is essential for people with back pain to reduce the risk of greater pain. For some people, the healthy alignment supported by Casper may even relieve pain over time. If you are waking up in pain, see the best mattresses for back pain.

Construction: What’s Under the Surface?

The Casper Original mattress is made from three layers of foam. The top layer is a soft and responsive polyfoam with holes throughout for generous breathability. The second layer is Casper’s zoned support memory foam, an ergonomic design that keeps heavier body parts supported while cushioning lighter areas like the feet and shoulders. These two layers create a light conforming feel that falls between sleeping “on” and “in” the bed. The final base layer of high-density polyfoam creates an all-foam feel with outstanding motion isolation and solid durability

Layer #1: Breathable Mattress Cover: Casper’s cover is made from a fabric blend that contains up to 57 recycled bottles. The fabric is soft, stretchy, breathable, and durable. 

Layer #2: Airscape Perforated Foam (1.5”): Casper’s proprietary Airscape foam is soft, delivering generous cushion along the mattress surface. By utilizing polyfoam instead of memory foam in this top layer, Casper maintains a slightly bouncy feel that supports ease of movement. 

Layer #3: Zoned Memory Foam (2”): A transition layer of ergonomically designed memory foam provides give and support to the areas that need it. This means softer foam along the top and bottom third of the mattress and firmer foam along the middle, creating a contouring and supportive feel.

Layer #4: High-Density Base Foam (7”): The final layer is a durable and dense polyurethane foam that brings a distinct all-foam mattress feel. This means excellent cushion and motion isolation.

How Do the Policies Measure Up? 

Shipping & Unboxing

The Casper mattress, available at Casper.com, Amazon, and retailers like Macy’s and Target, arrives rolled and compressed in a box. Shipping is free when you order directly through Casper Sleep to the continental United States and parts of Canada. Casper does ship to Alaska and Hawaii, but adds a shipping fee. Most orders arrive in two to five business days thanks to the abundance of Casper warehouses found across the U.S. and Canada. 

As with other bed-ina-box mattresses, the Casper may take a day or two before it’s ready to be slept on. The foams within take time to fully expand, and during this process, they release an odor known as off-gassing. Because Casper uses CertiPUR-US certified foams, you don’t need to worry about any health issues caused by the odor. Casper foams are certified to be low in VOCs and free from ozone depleters, formaldehyde, and heavy metals.

Unboxing is simple, but you may want to find a friend to help out because the mattresses are heavy. With two of us here at Mattress Nerd, it took us just about two minutes to remove the Casper from the packaging and unroll onto a bed frame.   


The Casper mattress comes with a 10-year limited warranty. The policy covers defects in materials and workmanship when used as intended, including using a proper foundation that adequately supports the mattress. The warranty covers sags greater than 1” that did not result from improper use or a weak foundation. It also covers any problems with the zippers or cracks in the foam.

Trial Period & Returns

The Casper Original comes with a 100-night trial period. What sets Casper’s return policy apart from most bed-ina-box mattress brands is that they accept returns at any time during the 100 nights. Most companies require you to keep the bed for a waiting period of around 30 days to allow your body to get used to the new feel. 

If you decide to return your new mattress during this time, Casper sends a courier to pick it up at your convenience. The brand tries to donate used mattresses to local charities but sometimes ends up recycling them. You should receive a full refund within two weeks of returning the Casper mattress.

Casper Mattress FAQs

Are Casper mattresses good?

Casper is one of the most popular bed-ina-box mattress brands with primarily positive customer reviews since they opened in 2014. They carry a wide selection of high-quality foam and hybrid models to fit the needs of diverse customers, and they back every mattress with a risk-free sleep trial. 

Do you need a box spring with a Casper mattress?

Casper recommends that you don’t use a box spring with their beds. Instead, they recommend an adjustable base, a slatted base with slats less than 4” apart, a foundation, or a platform base. A box spring isn’t as supportive as these other options and may cause damage to the bed. 

Do Casper mattresses sag?

Casper mattresses are unlikely to sag in the first seven to ten years of ownership so long as they are set atop a supportive base. Casper covers body indentations of greater than 1” during the 10-year warranty, so you’re covered in the case of a deep impression. 

Comparing the Casper Mattresses

Casper vs. Casper Element

The Casper Element and Original mattresses are both all-foam beds with a similar medium-firm feel. While both have the same soft Airscape top layer and high-density foam base, only the Original has a transitional layer of Zoned Support memory foam

The Zoned Support brings added softness to the shoulders and support to the core, which makes the Original a better fit for both side and stomach sleepers. Both beds work well for back sleepers, and the Element has a more competitive price point.

Casper Element

The Casper Element is not fancy. It features three memory foam layers, one each designed for comfort, support, and stability. Casper says all three are also breathable and able to release heat.

Casper vs. Casper Wave Hybrid

The Casper Wave Hybrid is Casper’s most luxurious mattress. It boasts thick foam comfort layers and pocketed coils that provide even better pressure relief and support than the Casper Original mattress. The Original is a slightly firmer mattress than the Wave, which leads us to recommend the Wave over the Original to side sleepers and lightweight people. 

While the Wave Hybrid does a good job at reducing motion transfer, it’s not quite as good for light sleepers who share the bed as the Casper Original. The Original comes at a much more affordable price than the Wave Hybrid

Casper Wave Hybrid

The Casper Wave Hybrid strikes a balance with a middle-of-the-road firmness level and features that make it appropriate for sleepers of all shapes and sizes. It’s an excellent choice for those who enjoy the Original Casper’s balance of conforming support but want more bounce.

Casper Original vs. Nectar Original Mattress

The Nectar is another leading memory foam bed-ina-box mattress. Because Nectar places its memory foam along the top layer, it has a more traditional memory foam cradling feel than the Casper mattress

While both of these beds have a similar medium-firmness, their feel is quite different. Casper’s top layer is a touch softer, and its Zoned Support means greater structure at the hips and spine. Lightweight sleepers tend to sink in better on the Casper, finding the Nectar’s surface too firm. The Nectar has a slightly lower price point than the Casper.

Check out our Casper vs. Nectar comparison to see how these two beds stack up. 


The Nectar is an affordable quality mattress with an excellent trial period. It suits all types of sleepers, couples and people who love sleeping on memory foam.

Casper Original vs. Puffy Mattress

The classic Puffy and Casper mattresses are both three-layer memory foam beds with a medium-firm firmness. One of the biggest differences between these mattresses is that Puffy uses memory foam on the top layer and polyfoam in the second layer, while Casper does the opposite. What this means is that the Puffy bed has more of a hugging memory foam feel, delivering superior pressure relief but sleeping slightly warmer. The Casper is easier to move around on. 

Another difference is that only Casper incorporates Zoned Support. What this means is that the Casper has a softer feel at the shoulders and firmer support at the hips. The greater core support means the Casper is a better fit for stomach sleepers.

Check out our Casper vs. Puffy comparison to see how these two beds stack up. 


Coined by some as "the internet's most comfortable mattress," this three-layer mattress is on the firmer side and suits back and stomach sleepers very well.

  • Minimizes Motion Transfer: The Casper is an all-foam mattress that does a good job of dampening motion rather than spreading it to your sleeping partner. Good motion isolation protects people who share the bed from frequent disruptions. 
  • Supports Healthy Spine Alignment: Casper’s zoned memory foam layer does an excellent job keeping the spine properly aligned, which is great for people with back pain
  • Cushions Pressure Points: Casper pairs a soft top layer with zoned memory foam that’s ultra-soft at the shoulders—a common area for pressure and pain for side sleepers. The combination makes the Casper a good pick for side sleepers
  • Good for All Sleeping Positions: Thanks to a medium-firm feel and zoned support, the Casper mattress works well for back, stomach, side, and combination sleepers. 


  • Can Sleep Hot: The Casper mattress sleeps too warm for many hot sleepers. Without any advanced cooling technology or breathable innerspring coils, the Casper can store body heat along the mattress’s surface. 
  • Not a Traditional Memory Foam Feel: Even though the Casper has a layer of memory foam, it uses plush polyfoam along the top of the bed. This means the Casper doesn’t have the hugging feel of a traditional memory foam bed, like a Tempur-Pedic mattress. 
  • No Innerspring Bounce: Some people love the bouncy feel of innerspring mattresses. As an all-foam bed, the Casper doesn’t have the same level of springiness as a hybrid or innerspring bed. 
  • Not Best for Heavyweight People: The Casper Original isn’t built for bigger bodies. With average support and relatively thin comfort layers, we don’t recommend the Casper for people who weigh more than 230 pounds.  

What’s the Bottom Line?

The Casper Original mattress is one of the best memory foam beds for people with back or joint pain. The Zoned Support means adequate give at the shoulders and sufficient support along the middle of the body, providing a balanced feel that works for back, stomach, and side sleepers. And for an all-foam mattress, the Casper is easy to move around on and works well for combo sleepers. 

Another group of people who tend to love the Casper is couples and people who share their bed with pets or kids. The Casper’s thick foam layers absorb motion rather than spreading it, helping people sleep together with fewer interruptions. And with a risk-free 100-night sleep trial, you get to try out the Casper in real life before committing to it for the long haul.
