Nectar and Casper are two leading bed-in-a-box companies. Their flagship mattresses come at a similar price point and offer great value for money. If you’re in the market for an all-foam mattress at an affordable price, then you’re on the right track.
The Nectar mattress features a memory foam comfort layer supported by a high-density polyfoam base. The Casper mattress is also an all-foam mattress but includes layers of open-cell polyfoam as well as memory foam in the comfort layers to add more bounce.
Casper makes five all-foam and hybrid mattresses in total. Both companies stock bed frames and bedding as well.
This review will stick to a comparison of the flagship Nectar vs. Casper mattresses, taking a look at construction, performance, sleeper ratings, trial periods, and other practical information to help you choose between the two.
How Are These Mattresses Built?
The Nectar and the Casper both contain memory foam comfort layers over a high-density polyfoam base. The main difference between the two mattresses is that the Casper also has polyfoam comfort layers, which gives it a more responsive feel. In turn, the Nectar has closer conforming due to more memory foam.
Given their similar construction, the Nectar and the Casper share some of the same advantages. However, slight differences in the type of foams and the height mean that each bed will appeal to different types of shoppers.
While all-foam mattresses can be fairly durable, they will eventually develop body impressions that can affect the level of comfort and support provided by the bed. Higher-density foams tend to last longer before succumbing to these impressions. The Nectar and the Casper use foams with similar densities, meaning they enjoy a comparable lifespan. All foams are also CertiPUR-US certified, meaning they are free of harmful substances like formaldehyde and ozone depleters, and low in volatile organic compounds (VOCs).
All-foam mattresses tend to be best-suited to sleepers under 230 pounds. Sleepers who weigh more than this prefer beds with coils or sometimes latex, which provide extra support.
The Nectar starts with a cover made from a blend of polyester, polyethylene, and nylon. The resulting fabric is soft and highly breathable.
The 3-inch comfort layer is made of gel memory foam, and this is followed by a 2-inch polyfoam transitional layer. These materials deliver close, even contouring without absorbing too much body heat.
The support core is made of 7 inches of high-density polyfoam. This is fairly standard for an all-foam mattress, and it provides a stable base to keep the mattress from bottoming out. The relatively high density ensures that sleepers of all body types, even those who weigh more than 230 pounds, should enjoy even spinal alignment with the Nectar mattress. The high density also helps lengthen the lifespan of the mattress.
The Casper has four layers in total and a cover made of 100 percent polyester. The bottom cover contains 98 percent polyester and 2 percent spandex.
Instead of just memory foam like in the Nectar mattress, the Casper’s comfort layer features layers of both polyfoam and memory foam. A layer of open-cell polyfoam on top of the mattress adds some initial resilience, reducing the “stuck-in-the-mud” feeling that can happen with memory foam and making it easier to move around. This layer is 1.5 inches tall.
Following this is a 1.5-inch layer of memory foam with a density of 4 PCF, which is considered medium density. This layer supplies the traditional “hug” feel of memory foam, contouring to the body to alleviate pressure points.
Next is a 1.5-inch transitional layer of polyfoam with a density of 3.5 PCF. In addition serving as a buffer between the comfort layer and the firmer base layer, this layer is also zoned. Firmer foam under the lower back and hips helps to keep the spine aligned, while softer foams in the rest of the layer ease pressure on sensitive areas like the shoulders.
The bed has a 7.5-inch polyfoam base layer, which is slightly taller than the Nectar mattress. However, the polyfoam has a lower density than the Nectar mattress, which is partly why it doesn’t rate as well with sleepers over 230 pounds.
How Do The Nectar and Casper Mattresses Feel?
Firmness refers to how hard or soft a mattress feels. It’s often described using a scale from 1 to 10, with 10 being the firmest. The vast majority of sleepers prefer a mattress that falls between 5 and 7 on the firmness scale, although it depends on your body type and preferred sleep position.
The Casper mattress has a firmness level of 5 out of 10, or medium. You’ll find that although the mattress offers some bounce, it also conforms closely to relieve pressure points, letting you sink in somewhat. This firmness level is ideally suited to back and side sleepers weighing less than 230 pounds.
In contrast, stomach sleepers and those who weigh more than 230 pounds will sink in too far and may find the bed too plush, meaning it will fail to keep their spines properly aligned.
The Nectar is a little firmer, coming in at a 6 out of 10, or medium firm. A thick memory foam layer conforms slowly to the sleeper’s body, providing a tight, firm cradle that keeps pressure from building up. You’ll mostly sleep “in” and not “on” this mattress.
At the same time, the Nectar provides more than enough support for most sleeper types, even those who weigh over 230 pounds. The exception is side sleepers who weigh less than 130 pounds. If you fall in this category, you may find the mattress a little too firm.
While neither mattress will be as bouncy as a latex or hybrid mattress, the Casper has noticeably more bounce than the Nectar. This is due to the top layer of polyfoam, which provides some responsiveness as soon as you lie down on the mattress.
While it’s really a matter of personal preference, most couples find that a bouncy mattress is preferable for sex. A bouncy surface facilitates motion and provides a responsive surface to push back against, making it easier to keep a rhythm.
For its part, the Nectar only has memory foam in its comfort layer. This means the mattress will have a very slow response to pressure and little to no bounce. Couples and combination sleepers will find that the non-responsive surface of the Nectar makes it harder to switch positions.
Although they’re quiet and very discreet, all-foam mattresses generally aren’t the best for sex. In addition to lacking bounce, they trap heat and tend to have weak edge support, limiting the positions you can adopt. However, if sex is important to you and you have your heart set on an all-foam mattress, the Casper is probably a better choice.
Responsiveness and motion transfer go hand-in-hand, since bouncier mattresses tend to transfer more motion across the surface. If you sleep with a partner, it may be hard to find a mattress that’s bouncy enough for sex, but not so bouncy that it wakes your partner up every time you roll over.
Edge Support and Ease of Movement
Edge support refers to how sturdy the edges of a mattress feel when you put pressure on them. Having good edge support helps minimize feelings of instability if you sleep near the edge of the bed, or if you frequently sit on the edge. A mattress with strong edges is also practical for people who share the bed, as it enables each party to use the full half of the bed without shrinking toward the middle.
Closely related to edge support is ease of movement, which describes how easy it is to change positions. In general, the firmer the mattress, the less you’ll sink into it, and the easier it will be to move around on top of the bed.
Ease of movement also depends on how responsive a mattress is. Sleeping on a non-responsive mattress can feel like sleeping in quicksand, as it adapts slowly to changes in pressure and hinders movement. This is why combination sleepers usually prefer more responsive mattresses.
Foam mattresses aren’t known for having good edge support or ease of movement. Most foams tend to compress easily and allow the sleeper to sink in, which inhibits movement and causes feelings of roll-off along the edges.
As expected, neither the Casper nor the Nectar stands out for its edge support or ease of movement. Both models feature close-conforming foams with a slow response to pressure, on par with other similarly constructed foam mattresses. That said, the Nectar uses slightly denser foams and has a firmer feel, which means the mattress offers slightly better edge support than the Casper.
A notorious drawback of memory foam is its tendency to trap heat. All-foam mattresses have little to no room for airflow, meaning that body heat has a hard time dissipating from the mattress. To combat this, many modern mattresses feature infusions of gel, graphite, or copper designed to pull heat away from the sleeper.
The Casper uses open-cell foams that let some heat escape, while the Nectar features a breathable cover plus gel-infused memory foam designed to distribute body heat. The Casper is slightly more successful at maintaining temperature neutrality.
However, if you often find yourself uncomfortably warm during the night, you might be better off with another type of mattress altogether. Hybrid mattresses allow room for airflow through their coils, while natural latex is highly breathable. Both are solid choices for hot sleepers.
As you can see, the Nectar and the Casper have different strengths despite being constructed with comparable materials.
With its breathable open-cell foams, the Casper stands out for its superior temperature regulation, making it the clear choice for people who sleep hot. This mattress also has a more responsive surface that lends itself well to sex and to combination sleepers.
In turn, the close-conforming memory foam layer in the Nectar offers unbeatable motion isolation, making it an excellent choice for people who sleep with a partner. The Nectar has a generous trial period and comes at a price-point that can’t be beat. If you’re on a budget, this might be the bed for you.
In terms of sleep position, the Nectar has a slightly firmer surface which will be more comfortable for stomach sleepers and individuals over 230 pounds. The plusher surface and zoned transition layer in the Casper adapt well to side sleepers, cushioning pressure points and ensuring proper spinal alignment. While the Casper is markedly more comfortable for side sleepers under 230 pounds, the Nectar has a medium-firm feel that is suitable for almost any body type and preferred sleep position, making it easy to find a compromise when sharing the bed.
Both mattresses excel at pressure relief, which is a common characteristic of all-foam beds. Each offers a balance of sleeping “in” and sleeping “on” the bed that works well for back sleepers. In terms of materials and construction, you can expect both mattresses to have a similar lifespan.
The Nectar and the Casper are both great choices, and neither one is technically better than the other. We can make recommendations based on the strengths we’ve found during our testing process. However, while we’ve found each mattress to stand out in different areas, everyone will interact differently with a mattress. The choice is ultimately up to you!
With all memory foam in the comfort layers, the Nectar mattress performs very well on motion isolation, helping limit disruption when sleeping with a partner. The polyfoam transition layer and high-density polyfoam base layer give the mattress added edge support. Overall, this is a good choice for people who share the bed.
The Casper has more bounce due to its polyfoam comfort layers, and the mattress succeeds in boosting airflow thanks to the open-cell foams. The mattress’s zoned transition layer provides adequate pressure relief and spinal support for side and back sleepers, especially those who weigh less than 230 pounds. If you like the feel of memory foam but you value being able to easily switch positions, this is an attractive option.
While both beds are priced affordably, the Nectar comes at a slightly lower price-point and offers a longer sleep trial, which might be appealing to indecisive shoppers.

Both the Casper and the Nectar are also available in brick-and-mortar stores.
Nectar backs its mattress with a 365-night sleep trial, which is much longer than most competing online mattress brands. After sleeping on the mattress for 30 nights, customers can return it at any time during the trial period if they are not satisfied. Nectar will provide a full refund, minus White Glove and shipping fees. Unopened mattresses are eligible for an immediate return.
Casper offers a 100-night sleep trial. Customers who aren’t satisfied with the mattress during this time can return it for a full refund. Casper does not impose a mandatory break-in period, although the company recommends giving the mattress 30 nights to allow time for the body to become accustomed to it.
Since both companies do their best to donate returned mattresses, they must be in appropriate condition and must have been used with an appropriate base. Soiled, smelly, stained, moldy, or otherwise mistreated mattresses are not eligible for return.
The Nectar mattress comes with a lifetime warranty covering workmanship and manufacturing defects. For the first ten years, Nectar will replace a defective mattress with a new one at no charge to the customer. After this, the company will repair and re-cover or replace your mattress and waive the transportation costs if the mattress is deemed defective.
Casper offers a 10-year limited warranty (3 years for trade customers) against defects in materials or workmanship. For mattresses that are deemed defective, Casper will repair or replace the mattress at the company’s discretion. Customers may choose to pay the difference to receive a more expensive replacement model.
The warranty terms for both mattresses are quite similar, covering physical flaws that cause degradation, splits or cracks in the foams, manufacturing defects in the cover, and visible indentations greater than 1.5 inches (Nectar) or 1 inch (Casper), unless these are the result of using the mattress with an improper base. Warranties do not cover comfort preferences, normal increases in foam softness that do not affect the pressure-relieving qualities of the mattress, or mattress that have been neglected, misused, abused, burned, cut, torn, spilled on, or stained. Warranties do not cover mattresses purchased used, as-is, etc.
