Nectar and Casper are two online mattress giants that nevertheless have quite different profiles. Founded in 2017, Nectar is a young disrupter that sells one mattress but has risen quickly to the top of the industry due to their advanced design, year-long sleep trial, and “forever” warranty. Meanwhile, Casper has been recognized as a leader in the mattress start-up sphere since 2013 for their innovative mattresses and standard-setting policies.

Although Casper currently has three mattresses for sale, this guide will just focus on comparing the Casper Wave to Nectar’s flagship mattress. Although they’re both multi-layered all-foam mattresses that target similar groups of sleepers, these mattresses contain key differences that better accommodate certain needs and preferences. In this guide, we’ll go over what these are, break down each mattress’ features and construction, and outline what you should pay attention to when making your final decision.

Mattress Construction Comparison


The Nectar is an all-foam mattress made of four layers, each one in a different variety of foam, that total 11 inches. The top-most comfort layer is made of one inch of quilted memory foam at 4 PCF. Gel-infused and topped with a temperature-regulating cover, it’s designed to keep the sleeper cool as well as cushioned. Another three inches of gel-infused memory foam, made of semi-open foam at 3.5 PCF, provides the sleeper with weight-distributed contouring and support, as well as additional cooling properties.

Underneath the two memory foam layers is the transition layer, 1.75 inches’ of adaptive hi-core 9.2-grade polyfoam, giving the mattress more contouring, support, and bounce. Finally, stabilizing the entire mattress is a base layer made of 5.25inches of 2.2 PCF polyfoam, breathable enough to let airflow through the mattress.

Casper Wave

The Casper Wave is made of five foam layers, totaling 13’ inches. At the top is a comfort layer made out of polyfoam. Plush and responsive, it’s designed to keep the sleeper cushioned and comfortable. Underneath the comfort layer is a layer of natural and synthetic latex foam, which is naturally cooling and breathable enough for maximum airflow. This is followed by a third layer of memory foam, designed to provide pressure point relief and contouring.

The fourth layer is made of gel-infused polyfoam. This layer is filled with gel pods that provide targeted support to the sleeper’s hips and core. Finally, a support core of dense polyfoam makes up the base layer. This layer is made with precise contouring that provides the sleeper additional zoned and targeted support. All of this is encased in a wool-infused cover that’s meant to keep the sleeper cool throughout the night.

Firmness Comparison

How comfortable you’ll sleep on your mattress depends largely on its firmness. Since everyone has a different preference and different firmness levels work for different weights, there’s no one right level of firmness. Instead, we rank all mattresses on a scale of 1-10, with 1 being the softest and 10 being the firmest. Generally speaking, soft mattresses (1-3) are best for side sleepers and those 130 pounds or lighter, medium-firm mattresses (4-6) work well for sleepers of most positions and weights, and firm mattresses (7-10) are best for back and stomach sleepers and those who weigh more than 230 pounds.

Both the Nectar and the Casper Wave fall in the medium-firm category, with the Nectar scoring a 6 and the Casper Wave scoring a 4.5-5. As a result, they should both suit the needs of most back, stomach, side, and combination sleepers who weigh between 130-230 pounds. Since firmness doesn’t affect how much support your mattress provides, the one that works best for you boils down to feel and personal preference. If you want slightly more firmness, you should opt for the Nectar, while the Casper Wave should be your choice if you want a plusher feel.

Sleep Experience

After firmness, the sleep experience offered by a mattress should be the most important determining factor in finalizing your purchase. This isn’t one factor, but a combination of different elements that dictate how hot you sleep, whether you’ll be able to feel your partner moving around, how responsive the mattress is, and much more.

Temperature Control

The temperature control of a mattress affects how hot or cold you’ll get throughout the night. As with all foam mattresses, both the Nectar and the Casper sleep somewhat hotter than an all-latex or innerspring mattress. The Nectar aims to fix this by infusing its foam layers with cooling gel, while the Casper Wave addresses this issue with its breathable wool-infused cover, latex layer, and “high-airflow perforations.” When it boils down to temperature control, we’d rate the Casper Wave higher than the Nectar.

Motion Transfer

Motion transfer refers to the ability of the mattress to control how much you feel your partner moving around on the other side of the bed. The less you can feel, the better the mattresses’ motion isolation. Because both the Nectar and the Casper Wave are made with multiple layers of foam, they both offer better motion isolation than mattresses made from latex or springs. Comparatively, though, the Nectar comes out on top.

While the Casper Wave’s latex layer contains some bounce that can lead to more motion transfer, the Nectar’s upmost layers total four inches of memory foam, making it better at motion isolation than the average foam mattress.


The responsiveness of a mattress refers to how readily the mattress conforms to give your pressure points proportional support. Due to the high contouring abilities of foam, memory foam mattresses offer superior responsiveness, which is true for both the Nectar and the Casper Wave. That said, the Nectar edges out the Casper Wave due to the amount of memory foam it uses in its comfort layers: 4 inches of memory foam, compared to 2.5 inches of responsive foam separated by 1.5 inches of latex in the Casper Wave.

Resilience and Bounce

Bounce refers to how quickly a mattressgoes back to its original thickness when you take off weight and pressure. This affects things like motion transfer and how easy it is to have sex on the mattress. Bouncier mattresses offer less motion isolation but are better for having sex. When it comes down to bounce, the Casper Wave is the clear winner due to its layer of latex. Meanwhile, the Nectar is built with exceptionally thick layers of memory foam, so it offers more conformity (with less bounce).

Edge Support

Edge support, as the name suggests, refers to how well the edge of a mattress can support your weight when you sit or lie there. Foam mattresses offer notoriously low edge support, and both the Nectar and the Casper Wave are no exception. That said, the density of the foam used in the Nectar does lend some support, so we’d put it slightly above the Casper Wave when it comes to this feature.

Off-gassing and Smell

Brand-new mattresses often release a noticeable odor during unpackaging which can stick around for anywhere from a few hours to a few days. This is called off-gassing. Both mattresses’ off-gassing processes can take from a few hours to a few days, so we’d rank them around the same when it comes to smell.


Shipping, Trial, Warranty, and Returns

The shipping, trial, warranty, and return policies offered by a brand should not be discounted when you’re shopping for a mattress. These policies affect everything from how soon you’ll get your mattress, to how long you’ll get to test it out for and how easily it can be returned if it doesn’t work out.

Prices, Sizes, and Value

While the sleep experience offered by a mattress should be the most important factor in determining which one is best for you, price shouldn’t be ignored. You should look for a mattress that is within your budget, worth its value, and proportionally priced for its size.

Twin XL$569$1,595
California King$1,099$2,795

The Casper Wave is the more expensive mattress, having a price-tag around 2.5 times that of the Nectar. If you’re looking for the more affordable foam mattress, then the Nectar is the more worthwhile choice. Nectar’s year-long sleep trial and “forever” warranty (compared to the Casper’s 100 nights and 10-year warranty) also make it an excellent pick for its value. That said, the Casper Wave does solve two key issues with most foam mattresses better than the Nectar: temperature regulation and bounce. Whether this is worth the extra money depends on how important these elements are to you.


Nectar Mattress vs. Casper Wave Mattress – Which One Should You Buy?

Even after considering all these factors, you still might not know whether the Nectar or the Casper Wave is the better choice for you. To help you decide, we’ve narrowed down each option’s biggest defining features below.

Buy the Nectar mattress if you:

1. Want better motion isolation

The Nectar’s dense layers of memory foam are highly responsive and conform to the sleeper’s body, which makes it great at isolating movement. If not being able to feel your partner’s movements on the other side of the bed is important to you, then you should go with the Nectar.

2. Require more edge support

Although most foam mattresses offer poor edge support, the Nectar’s layers of dense foam lead to less sinkage on the perimeter than average.

3. Want a mattress that conforms more

The Nectar’s four inches of memory foam in its topmost layers make it the better choice when it comes to conformity. These comfort layers contour well to the body, so you should opt for the Nectar if you want a mattress that more closely cushions your pressure points.

4. Need a year to try out your mattress

At 365 nights, Nectar offers a far longer sleep trial than most mattress companies, so if you need more time to decide whether your bed will work out, this is a good choice.

Buy the Casper Wave mattress if you:

1. Want a plusher mattress

Both the Nectar and the Casper Wave are in the medium-firm category, but the Casper Wave is plusher by 1-1.5 levels. Therefore, if you want the support of a medium-firm mattress but with a softer feel, you should opt for the Casper Wave.

2. Want more temperature regulation

The Casper Wave is made with a breathable wool cover, a layer of latex separating its top-most foam comfort layers, and perforations that allow for high airflow. This makes it great at temperature regulation, and a good choice if you want to sleep cooler throughout the night.

3. Want more bounce

Due to the layer of latex in its top layers, the Casper Wave is by far the bouncier mattress. This makes it a good mattress for sex, and there’s no issue with sinkage or restrictive conformity.

Casper Wave

Both the Nectar and the Casper Wave are excellent multi-layered foam mattresses that address a lot of the issues typically found with this material. Both mattresses offer superior cooling properties, as well as higher-than-average support. If price is your biggest concern, then you should go for the Nectar, which is half the price of the Casper Wave. Otherwise, which mattress you should choose will boil down to a handful of preferences, as well as how much you like the qualities inherent to foam mattress. Do you prefer the high conformity, “hugging” feel, motion isolation, and low bounce of memory foam? Then the Nectar will better suit your needs. If, on the other hand, you don’t like these qualities and want a plush mattress that has better cooling properties, bounce, and edge support than an average foam mattress, then you should go for the Casper Wave. Either way, they’re both great choices if you’re the type of sleeper who works best with foam mattresses.
