Casper Mattress Ratings

The ratings – based on 230+ consumer reviews gathered using an unbiased, accurate methodology – show how Casper mattress rates in comparison to the average mattress.

Owner satisfaction B The Casper mattress has 80% owner satisfaction. Learn more.
Durability / longevity B Long-term owner data is limited but suggests that the mattress has better than fair longevity (at least 6.5-year lifespan) on average. More.
Support B- Support appears to be no worse than average, but some large people and couples may find it inadequate.
Less (back) pain B- While about 11% of owners (1 in 9) report reduced back pain, about 7% (1 in 14) report new back pain since sleeping on their Casper mattress. (See mattresses and pain relief for general analysis.)
Conforming B A highly conforming mattress is one that molds and contours to the sleeper's body resulting in a cradling, cloud-like, pressure-point-free sensation. Casper performs above average, but better conforming beds are available – namely those with more memory foam content.
Easy to move on B- The mattress does not tend to conform to a degree which makes moving on the bed and getting up off of it difficult. About 5% of owners (1 in 20), usually large people, report difficulty of movement.
Motion isolation B Casper to a significant extent prevents one person's movement from disturbing another person on the bed, but it does not eliminate such disturbance. Consumers coming from a memory foam or pocket coil bed are most likely to be disappointed with Casper on this issue.
Edge support D As is often true for foam-based mattresses, support near the far edge may be inadequate for sleeping or sitting, especially for larger people.
No initial off gassing C+ About 8% of owners (1 in 15) report a significant and enduring unpleasant initial off gassing odor. More.
No sleeping hot C+ Significant and bothersome heat retention is reported by about 6% of owners (1 in 17). More.
Good for sex B- The Casper mattress has some spring but little if any bounce. (See mattresses and sex for general analysis).
No noise A Like other foam-based mattresses, Casper is silent.
No topper needed B- About 7% of owners need to add a topper to the mattress to improve softness and comfort. Learn more.
Fast break in C+ About 12% of owners report an extended break-in period.
Easy to maintain C+ The Casper is one sided and no flip. Rotating it (head to foot) on occasion may be necessary to prevent and minimize sagging / wear.
Easy to lift, handle, move B- The mattress weighs 55 to 103 pounds depending on size which is about 15% lighter than the average mattress. There are no handles.

Casper Company Ratings

The ratings below – based on consumer experiences and the evaluation of Sleep Like The Dead – show how Casper compares to the average mattress manufacturer.

Warranty C Casper provides a 10 year non-prorated warranty. The company appears to honor all legitimate warranty claims. (See mattress warranties: what you should know.)
Return policy A Casper provides a 100-day, no-fee, 100%-money-back trial period. No preparation for return shipment is necessary, and a courier (if available in your area) removes the mattress from your home to be recycled or donated. There is no minimum amount of time the mattress must be kept before being eligible for return. When buying from Amazon there is a 30-day return window and the mattress must be returned to Amazon.
Customer service A Overall, customer service is regarded by consumers to be excellent.
Marketing accuracy D+ A central claim by Casper is that their mattress is "perfect for everyone" and "universally comfortable." But at least 20% of customers would likely disagree with this claim. And about 6% of customers would disagree with the claim that the mattress "keeps you cool."
Access to customer reviews A- At its website, Casper allows filterable and easy access to all customer reviews posted there, including those that are negative.
Integrity of customer reviews B+ This refers to how closely customer ratings appearing on Casper's website correspond to customer ratings at independent sources.
Specs disclosed B By openly disclosing mattress specifications, a company allows consumers to know what they are paying for and helps them to comparison shop. Layer thickness and density are available upon request but do not appear to be on the Casper website.
Time in business C- Casper began in 2014 which is recent but nevertheless earlier than the start date of most of its main competition. Buying from a newer, less established company comes with increased risk because the kinks have likely not been worked out. Also, the company has not shown the staying power to be available in the future to give customer service and to process warranty claims.
BBB rating A+ Casper Sleep has an "A+" with the Better Business Bureau. Five complaints have been filed against the company.
SLTD rating B SLTD (Sleep Like The Dead) company rating for Casper is determined by averaging the above company ratings.

Casper Firmness Analysis

In April 2016, Casper altered the design of their mattress to be softer. The firmness of the previous design was established as medium-firm for owners on average, but the firmness level of the new design is less clear. Available owner experience data suggests that it is more medium than medium-firm (after break in) on average.

In other words, on a 1 to 10 scale with 1 being very soft and 10 being very firm, Casper appears now to on average be regarded as a 6 or 6.5. This firmness level suits most owners but not all. Beyond break-in about 9% of owners find it too firm and about 7% find it too soft. About an additional 15% find the firmness to be acceptable but not ideal.

It should be noted that in early 2017 Casper changed the top comfort layer from latex to regular foam. Casper says that this change has not altered the firmness level of the mattress, but owner experience data will need to be gathered to confirm this.

Casper Specifications Analysis

The following discusses the construction of Casper, its thickness and its weight.

Top Layer

The top layer consists of about 1.5 inches of regular foam.

Middle Layer

The middle layer consists of 1.5 inches of memory foam. The memory foam has 4 lb/ft density.

Base Layers

The transition or top base layer consists of 1.5 inches of 2.5 lb/ft density foam. The bottom base layer consists of 5 inches of 1.8 lb/ft density foam. The densities of these two foams combined is slightly higher than the base layer(s) densities of both foam-based mattresses on average and Casper's main competition on average.

In general, higher density foam used in the base layer(s) is a durability / longevity strength as softening and loss of support tend to be less likely to occur with the use of such foam.

Total Thickness

Casper is about ten inches in total thickness. This is about 1.5 inches thinner than the thickness of the average mattress but similar to that of its main competition on average. A thinner mattress is lower and therefore may be somewhat more difficult to get on and off for people of average or greater height.

Casper weighs 55 to 104 pounds depending on size which is about 15% lighter than the average mattress. A light mattress may have the disadvantage of not staying firmly in place on its base but the advantage of being relatively easy to move, lift and handle.
