In this review, we will compare the two flagship mattresses of Bear and Casper. The two companies were founded within a couple of years of each other in 2015 and 2014, respectively. Both companies have excellent reputations for customer service and quality and offer mattresses that are made in the USA.

Bear and Casper ship their mattresses compressed in a box right to your door. Both companies offer sleep trials and limited warranties. But the differences in their flagship mattresses are also significant.

Both Bear and Casper make a multi-layer combination polyfoam and memory-foam mattress at a similar price point. Depending on your needs you may like one more than the other based upon your sleep positions, body type, and how hot or cool you sleep.

Bear offers a unique breathable Celliant® Cover that uses infrared technology approved by the FDA for promoting rapid recovery in athletes in their memory foam 3-layer mattress. Casper provides a zoned layer with two different firmness levels for greater support and alignment in their 4-layer memory foam mattress.

In this review, we will be comparing the original Casper all foam construction mattress to the Bear Mattress. Read on as we go into a detailed comparison of these two flagship mattresses.

Mattress Construction Comparison


The Bear’s 10-inch foam mattress is constructed of three layers of responsive foam topped with a breathable polyester Celliant® cover that acts as an FDA-approved wellness device promoting restful sleep, circulation, and enhanced recovery times for athletes.

  • The bottom support layer is 6.5 inches of high-density polyurethane support foam for durability and stability.
  • The middle layer of the Bear is 2 inches of softer responsive transition foam for pressure relief and balanced support and alignment of the spine.
  • The top layer of foam is 1.5 inches of cooling graphite-gel memory foam designed to disperse body heat and keep you cool throughout the night.
  • The Celliant® breathable cover is one inch of stretchable fabric with infrared threads woven in to help speed healing and recovery time for muscles.

The firmness of the base layer of foam combined with the softer responsive layers makes this a medium-firm mattress. Because of the newer graphite-gel memory foam, you will not feel the sinking in the sensation of more traditional memory foam mattresses. All the foams in the Bear mattress are CertiPUR-US Certified.


Casper popularized the bed in the box trend back in 2014; their  combination foam mattress is 12 inches high.

  • The 6-inch foundation layer creates durability and support for the other layers. (Casper also offers a hybrid mattress choice made of steel pocket coils for this base layer).
  • The second layer is a two-inch Zoned support transition layer which means it gives firmer hip support and is softer and more responsive for the legs and shoulders. Zoning gives more pressure relief to the shoulder area to optimize spinal alignment.
  • The third layer just below the top layer is two inches of responsive high-density memory foam that helps with cradling and conforming to your curves without too much of a sinking-in sensation. This layer helps with motion isolation.
  • The top layer of foam is a bouncy, responsive two-inch open-cell proprietary comfort foam for air circulation that keeps you cool. This layer offers surface comfort and pressure relief.
  • The Casper mattress cover is 100-percent polyester.

All the foams in the Casper mattress are CertiPUR-US Certified.

Firmness Comparison

The firmness level of a mattress is measured on a scale of 1 to 10, with one being the softest, and ten being the firmest. The perceived firmness level of your mattress is highly subjective and depends on your size and weight and sleeping style. If you are petite, a mattress may feel firmer to you because you will not sink in as far as much as a heavier person. While a more substantial person will sink deeper and perceive the very same mattress to be softer than a smaller person.

Sleep positions will also be a factor for choosing the firmness level you desire in a mattress. Combination sleepers will find both the Bear and Casper to be supportive and comfortable.

The Bear and Casper signature mattresses have been constructed to be medium-firm, making both mattresses versatile and popular with couples and most sleepers of average size. If you know that you like a soft, plush feel, you may find both of these mattresses a bit on the firm side. If you weigh over 230 pounds you may find these middle-of-the-road mattresses a little too soft.

The Bear has a firmness level of 6.5 to 7 depending on your size and shape, on a scale of 1 to 10 with ten being the firmest. Bear is a versatile mattress with a medium firmness level that makes it an excellent choice for couples. If you are very petite you may find the Bear slightly firmer than you like.

Casper’s 2019 version is a bit firmer than it was in the last two years going from a four in 2018 to a five to 6.5 out of ten firmness level for its 2019 model. Again, how firm the Casper will feel to you will depend on how you sleep and how much you weigh. With the zoned layer of foam, you will notice a difference in softness depending upon how high or low you position yourself in the bed and what position you sleep in. Heavier sleepers may find the Casper a bit too soft.

Sleep Experience

When you are choosing a mattress, it is essential to consider several elements:

  • Temperature Control: Does the mattress have a way to keep you cool if you sleep hot? Foam mattresses tend to absorb and hold heat.
  • Motion Transfer: If you sleep with a partner, and you are a light sleeper, it is crucial to find a mattress that reduces motion transfer for uninterrupted sleep.
  • Responsiveness: Does your mattress support your curves and allow your shoulders and hips to sink in enough for spinal alignment and support? How fast does the shape return when you move?
  • Resilience and Bounce: Is your mattress easy to maneuver on, or do you feel like you’re stuck in the mud?
  • Edge Support: Edge support refers to the reinforced edge of a mattress and how well it resists wear and sagging. Foam mattresses usually do not offer reinforced edge construction.
  • Off-Gassing and Smell: What types of chemicals are in your mattress and how long will it take for them to dissipate once you unbox your new mattress?

Temperature Control

Bear has created a soft Celliant® breathable cover. Just below the breathable cover is one and a half inches of cooling graphite-gel infused transition memory foam designed to dissipate unwanted body heat. Most customers report that the Bear is cooler than other all-foam mattresses.

Casper has dealt with the problem of heat retention in foam mattresses by using a breathable open-cell technology for the top layer of foam. This special foam is designed with tiny pores to release excess heat, so you sleep cool and comfortable.

Both of these mattresses have solved the problem of the heat-trapping characteristics of foam with newer technologies that will keep sleepers cool.

Motion Transfer

Foam mattresses are generally excellent at trapping motion in the denser foundation layers. You won’t feel your partner moving throughout the night. Bear has a six-inch high-density foam base that makes it highly stable and quiet. Casper has similar stability with its core structure but has slightly more bounce to the top layer of foam than Bear. Sensitive sleepers may notice a partner moving throughout the night more on a Casper mattress than on a Bear mattress.


Responsiveness used to be a problem with memory foam which would mold into one body contouring shape and take a long time to recover. With the newer combination foam layers, the Bear signature mattress is quite responsive. The top layer hugs the body but not so much that you find it difficult to change positions.

With the Casper mattress, the responsiveness of the top layer of foam is springy and fairly easy to push into. The Casper has gentle cradling support and easy maneuverability without feeling stuck or sinking in too far.

Resilience and Bounce

The Bear mattress has enough spring to keep you from sinking in when you try to maneuver into different positions. The feel is more of being on the surface of the bed than in the bed.The Casper’s top layer of foam is responsive and bouncy enough for unhampered maneuverability making it suitable for sex while still being very supportive for sleep.

Edge Support

Edge support is especially important for couples who will be sharing the mattress and need to utilize the full surface. One problem with foam mattresses is that they tend to lack adequate edge support in contrast to more expensive hybrid and spring construction mattresses.

The Bear mattress has no reinforced edge support around the perimeter of the mattress construction, which can lead to sagging and break down over the years. However, the 6-inch high-density support foam at its base helps this mattress maintains its shape.

The Casper mattress has edge support that is relatively good for a foam mattress. Because of the high-density polyfoam support core, you will get full use of the sleeping surface for a long time.

Off-gassing and Smell

Bear and Casper mattresses have little to no smell according to customers and will off-gas slightly for the first 48 hours. Both of these companies use CertiPUR Certified materials and are safe for home use.

Casper and Bear use construction materials that are free of Polybrominated Diphenyl Ethers (PBDE) flame retardants, mercury, lead, and other heavy metals and free of formaldehyde.

Prices, Sizes, and Value

Both the Bear and Casper Signature mattresses are high quality and a great value for the price but Casper is a slightly higher price point than the Bear due to it’s zoned foam layer and slightly thicker foam profile.

Twin XL$640$695
California King$940$1,295
  • Bear is slightly less expensive but it has a lower foam profile and less edge support.
  • Casper has slightly more durability due to thicker foam. If zoning is an important consideration this extra layer may be worth it for you.
  • The Bear offers a unique healing and recovery element with its patented Celliant cover which can be a plus for athletes or people with joint stiffness.
  • With only $100 difference, price is not the determining factor between these two mattresses. Comfort and support and individual preferences are the deciding factors.

Bear vs. Casper Mattress – Which One Should You Buy

Even after considering all these factors, it can be challenging to decide whether to choose the Bear or Casper mattress. Which one is right for you? They are both designed for a wide range of sleepers and have a lot to offer, so we’ve created a list of differentiators.

Bear is a safe pick at a reasonable price point. The neutral foam feel is accommodating and comfortable for most sleepers, especially those who like a slightly firmer mattress. The Infrared cover makes it especially suitable for athletes.

Casper is one of the most recognized companies for a bed-in-a-box mattress. Casper is an excellent choice for value shoppers. Casper is good for couples because of the neutral quality of the foam. Casper is especially useful for medium to small sleepers looking for a medium firmness at a moderate price.

4. Are a side sleeper over 230 lbs

You may find just the right level of softness, support, and responsiveness for a comfortable night’s sleep.


Buy the Casper mattress if you:

3. Want zoned support or are a side sleeper

Zoned support means additionally supportive and responsive foam under shoulders and hips in all positions.
