Casper and Helix are both well-known online mattress companies. Casper launched in 2014 and is one of the leading names in the bed-in-a-box movement. Helix launched in 2015 and became well known for its customizable mattresses and its sleep quiz that matches customers with a mattress.
The Casper mattress and the Helix mattress both offer clear advantages. However, comparing the Casper mattress and the Helix mattress on construction, sleep experience, and product information may help you make the right decision for you.
Each company produces multiple mattress models, but this comparison will take a narrower approach. While Casper also offers the Wave and the Essential, the following comparison will focus on the Casper. Helix produces quite a few mattress models, including:
- Dusk Luxe
- Twilight Luxe
- Dawn Luxe
- Sunset Luxe
- Moonlight Luxe
- Midnight Luxe
For the sake of this comparison, we’ll focus exclusively on the Midnight.
Mattress Construction Comparison
The Casper mattress used to be 9.5 inches high, but was recently upgraded to be 12 inches high. The mattress features four layers of premium memory foam for cooling, comfort, pressure relief, and alignment. Specifications on the exact thickness and density of the layers are not currently available.
The top layer of the Casper mattress is composed of open-cell comfort foam designed to provide greater airflow and promote a cooler night’s sleep.
The Casper’s second layer uses high-density memory foam that contours to the body for pressure relief.
The third layer is a transition layer. It uses Zoned Support to offer targeted support to key parts of your body. The foam is soft under the shoulder area, relieving pressure. However, it is firm under the hip area to support spinal alignment.
The base layer uses dense foam for extra support and durability. If you select the hybrid version of the mattress, however, the base layer uses springs instead of foam to add bounce and breathability.
The Helix is a 10-inch tall hybrid mattress that pairs three layers of foam with a layer of support coils. The comfort layer uses Memory Plus Foam, which is Helix’s proprietary foam blend designed to provide contouring and cushioning, thereby relieving pressure. This foam has a density of 2.5 PCF (pounds per cubic foot).
The transition layer uses high-grade polyfoam. This layer is intended to provide both support and cushioning.
The next layer of the mattress uses hundreds of wrapped coils to contour to the body without excessive motion transfer. This layer also features a reinforced edge. The base layer of the Helix mattress uses DuraDense foam for added support and durability.
The Helix mattress’s cover is composed of polyester, which offers stretch. The cover also aims to allow enough airflow to promote a cooler night’s sleep.
Mattress firmness is often one of the key determining factors in how comfortable a mattress feels. Firmness refers to how soft or hard a mattress feels, and it also plays a major role in spinal alignment.
While mattress firmness is a personal preference, factors like weight can also play a role. Sleepers over 230 pounds may benefit from a firmer mattress that prevents them from sinking in too deeply, while sleepers under 130 pounds may need a softer mattress in order to sink in at all.
The materials and construction of a mattress can affect its overall firmness. Materials like foam are often soft. However, when layered, they can also be used to create firmer mattresses.
A 10-point scale is commonly used to rate mattress firmness. Soft mattresses fall on the lower end of the scale, while firm mattresses are assigned higher numbers. It may help to think of a 1 as sleeping on a cloud and a 10 as sleeping on concrete. This scale provides a convenient tool to judge a mattress’s firmness and compare your options.
The Casper mattress is a medium-firm option, rating between 6-7. Because it falls in the middle of the firmness range, it may appeal to a variety of sleepers.
The Helix mattress is also medium-firm, rating around 6.5. Like the Casper mattress, the Helix’s firmness should be able to accommodate a variety of sleepers.
Sleep experience encapsulates several key factors that can impact the quality and comfort of your sleep. When selecting a mattress, it is important to consider how it will perform in areas like temperature control, motion transfer, responsiveness, resilience and bounce, edge support, and off-gassing. We’ll show you how the Casper mattress and the Helix mattress compare in these areas.
Temperature control refers to whether or not a mattress traps heat. Memory foam mattresses frequently trap heat near the body, which may be uncomfortable for some sleepers. Mattresses that offer better airflow or cooling technology may be more comfortable for those who tend to sleep hot.
The Casper mattress isn’t excessively soft, so it can prevent you from sinking in too deeply and therefore reduce heat retention. Additionally, the Casper mattress has a top layer of open-cell polyfoam allow for better airflow.
The Helix mattress features a cover designed for breathability. The innerspring layer used in hybrid mattresses like the Helix can also allow for greater airflow than most all-foam mattresses.
While each mattress approaches temperature control differently, both the Casper mattress and the Helix mattress offer a cool, comfortable night’s sleep.
Motion transfer occurs when one partner moves and that movement is felt across the surface of the bed. If you have a partner who moves around a lot during the night, this can lead to sleep disturbances.
Memory foam often absorbs motion and therefore prevents motion transfer. Like many other memory foam mattresses, the Casper mattress performs well in motion isolation.
While the Helix mattress offers good motion isolation, the addition of springs may lead to slightly more motion transfer than all-foam mattresses like the Casper.
Responsiveness is how a mattress adjusts to the weight of your body parts to provide appropriate cushioning. A responsive mattress will allow your wider, heavier body parts, like your hips, to sink in. Because it adjusts to your shape, a responsive mattress can help promote spinal alignment.
The top two layers of the Casper mattress offer contouring, while the Zoned Support transition layer provides the necessary softness and support to promote proper alignment.
The Memory Foam Plus comfort layer of the Helix mattress offers contouring. The transition layer offers support and ergonomic cushioning. The wrapped coils further cradle your body. These features create an appropriately responsive sleep surface.
Both the Casper and Helix mattresses may be able to provide sufficient responsiveness to promote healthy spinal alignment.
Resilience and Bounce
Foam mattresses may take some time to regain their shape after weight is removed. Resilience is how quickly this happens. When a mattress regains its shape quickly, it’s said to have “bounce.” Resilience and bounce can contribute to how easy it is to move around on the mattress surface during the night. They can also facilitate sexual activity.
The Casper mattress’s top layer is composed of polyfoam, which offers greater resilience and bounce than many memory foam mattresses.
Since the Helix is a hybrid mattress, it may outperform the Casper mattress in resilience and bounce. The wrapped coils in the Helix mattress provide bounce like a traditional innerspring mattress, which is generally superior to that of an all-foam mattress.
As is standard with all-foam mattresses, the Casper mattress lacks reinforced edges. This means that the foam may compress when you sit or sleep near the edge, which can create a feeling of instability.
The Helix mattress offers edge support in the coil layer. This edge support can make it easier and more comfortable to sit or sleep near the edge of the bed.
Off-gassing and Smell
Since both the Casper and the Helix mattresses contain foam, either mattress may emit a slight odor when first introduced to your home. While the odor isn’t harmful, some people may find it displeasing. The odor should dissipate within a few hours to a couple days, as long as the mattress is left in a well-ventilated space.
Shipping, Trial, Warranty, and Returns
A mattress is a big purchase, and the delivery fees, shipping methods, old mattress removal, trial length, return cost, and warranty length may all be important factors to consider. While Casper and Helix are identical in these factors, it is still important to know what you’ll get for your money.

Prices, Sizes, and Value
Price can be a determining factor when selecting a mattress. You may need to select an option that still leaves you extra money to spend on a base, sheets, pillows, and other sleep accessories. Here is how the Casper and Helix mattresses compare on price.
The Casper mattress and the Helix mattress are quite similar in price. While the Casper mattress is less expensive for the twin, twin XL, king, and California king sizes, the Helix is less expensive for a full size mattress. The Casper and Helix come in at the exact same list price for a queen size mattress.
Both companies frequently offer promotions. Codes can often help you save around $50 on the Casper mattress. Helix may offer more valuable codes, saving you around $100 on the Helix mattress. Because of these discounts, you may be able to purchase the Helix mattress for slightly less than the Casper mattress, but the savings would not be significant.
Casper Mattress vs. Helix Mattress – Which One Should You Buy?
Since the Casper mattress and the Helix mattress share so many similar features, it might be hard to decide between the two. Considering all the factors can help, but the following list of differentiators can give you a quick overview of the most significant differences between these two mattresses.
Buy the Casper mattress if you:
- Prefer an all-foam mattress: The Casper mattress is composed entirely of foam, so it is an appropriate option for customers looking for an all-foam mattress.
- Value motion isolation: The Casper and other all-foam mattresses offer strong motion isolation. This means that if your partner tosses and turns during the night, you’re less likely to feel it with the Casper mattress.
Buy the Helix mattress if you:
- Prefer a hybrid mattress: If you are looking for a hybrid mattress, the Helix can fit the bill. It uses a combination of foam layers and an innerspring layer to offer comfort, support, and alignment.
- Want extra resilience and bounce: The use of innersprings in the Helix mattress may provide extra resilience and bounce. This could aid sexual activity or changing position during the night.
- Want edge support: If you like to sit or sleep close to the edge of the bed, you might benefit from added edge support. Edge support can make the edge of the bed feel more stable. Since the Helix mattress offers reinforced edges, it can be a good option for anyone looking for edge support.
The Casper and the Helix mattress are very similar in price, firmness, responsiveness, and more. The main difference between the two mattresses is their construction. The Casper mattress is an all-foam mattress, while the Helix uses a hybrid design. These different construction methods lead to the most notable differences between the mattresses. The Casper mattress may offer better motion isolation, while the Helix mattress offers greater edge support and may provide extra resilience and bounce. Both mattresses have advantages, so you will need to consider what features are most important to you in order to select your mattress.
