Casper Mattress Ratings

The ratings – based on 260+ consumer reviews gathered using an unbiased, accurate methodology – show how Casper rates in comparison to the average mattress.

Owner satisfaction B The Casper mattress has 80% owner satisfaction. Learn more.
Affordable B The mattress is priced $550-$1150, not including a foundation. More.
Durability / longevity B Long-term owner data is limited but suggests that the mattress has an above-average lifespan. More.
Support C+ Support appears to be no worse than average, but some large people and couples may find it inadequate.
Minimizes pressure B+ Casper tends to conform effectively to a sleeper's body, often resulting in above-average distributed support and pressure-point relief.
Less (back) pain B The at least fair degree of support and conforming ability of the Casper result in above-average potential for back pain relief. (See mattresses and pain relief for general analysis.)
Easy to move on / get up off 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 (1 in 14) need to add a topper to the mattress to improve softness and comfort. Learn more.
Fast break in C+ Average break-in time for Casper appears to be about 10 to 15 days.
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 lbs depending on size which is about 15% lighter than the average mattress. There are no handles. More.

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 B Claims made by Casper about their mattress are essentially factual with only moderate hyperbole.
Access to customer reviews A- At its website, Casper allows filterable and convenient access to all customer reviews posted there, including those that are negative.
Integrity of customer reviews B+ This refers to how closely customer ratings at Casper.com correspond to customer ratings at independent sources. In total, ratings at Casper's website are only moderately higher than those found at independent sources. Casper performs better on this issue than its main competitors.
Specs disclosed C+ By disclosing mattress specifications, a company allows consumers to know what they are paying for and helps them to comparison shop. Most specs are provided on the website, but layer thickness and density are not; such information however may be available upon request.
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 less established brand often comes with higher risk because the company has not had the time to smooth the kinks that come with running a new business and selling a new product.
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 their mattress to be softer. The firmness of the previous design was established as medium-firm for owners on average. The firmness level of the new, current design 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.

It should be noted that in early 2017 Casper changed the top comfort layer from latex to a type of regular foam. This change does not appear to have altered the general feel or firmness of the mattress.

Casper's 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.

Compared to its main competitors, the Casper mattress currently appears to have a firmness / support level that is at least slightly better suited for the average person. Of course, your own individual evaluation may differ.

Person Size and Sleep Position Suitability For Casper Mattress

The table below evaluates the Casper mattress for person size and sleep position. It shows what tends to be true for Casper owners; your own personal evaluation may differ.

See the mattress firmness guide for details based on your body type. And people of below- and above-average weight, see the mattress guide for large and small people.

  Average-Sized People
(130-230 lbs)
Heavy People
(230+ lbs)
Light People
(under 130 lbs)
Back Sleep Friendly B+ B- B
Side Sleep Friendly B C+ B-
Stomach Sleep Friendly B C B

Average-Sized People

The Casper mattress is best suited for people of average size (130-230 pounds). Nevertheless, about 7% of average-sized side sleepers report excessive firmness (beyond break-in) resulting in hip and or shoulder pain. Those with a body mass index of 20 or lower appear most likely to report excessive firmness.

Heavy People

Most Casper owners 230+ pounds report that the mattress is adequate. The comfort layer is thick enough to mostly prevent one's shoulder or hip from reaching the firmer layer(s) underneath. However, the support provided by Casper's main competitors may be superior for large people. And overall thickness may be inadequate to prevent bottoming out especially when sitting.

Light People

About 12% of Casper owners under 130 pounds – especially side sleepers – report excessive firmness. According to them, this is likely due to not weighing enough to exert the pressure needed for the bed to conform to their bodies. Those with a body mass index of 21 or lower appear most likely to report excessive firmness.

Casper Specifications Analysis

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


The cover is 100% polyester. Most main competitors use a polyester blend.

Top Layer

The top layer consists of 1.5 inches of a type of regular foam (3.5 lbs/ft density) which is basically similar to that used by nearly all of Casper's main competitors.

Middle Layer

The middle layer consists of 1.5 inches of 3.5 lb/ft density memory foam. Casper's main competitors with the exception of Leesa do not use memory foam in their mattress. The presence of memory foam may be chiefly responsible for Casper being at least slightly more likely to sleep hot than most of its main competitors.

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, 1.8 lb/ft density or higher foam used in the base layer(s) is a durability / longevity strength as softening and loss of support appear to be less likely to occur with its use.

Total Thickness

Casper is about ten inches in total thickness. This is about 1.5 inches thinner than the average mattress but is very similar to that of 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.
