What You Need to Know about Casper Mattresses

Mattress Type and Components:

  • Casper offers memory foam mattresses. The company lists three different models in its current lineup:
    • The Essential is constructed with a top layer of polyfoam and a bottom layer of memory foam in the comfort system, and a support core made of high-density polyfoam. The cover is an unspecified knit.
    • The Casper has a comfort layer with three separate components: a middle memory foam layer placed between top and bottom layers of polyfoam. The support core is constructed from polyfoam, as well. The paneled cover is made from a blend of several fabrics, primarily polyester and rayon.
    • The Wave has a comfort system with four primary components: a top layer of ‘Flo Foam’ pillow top polyfoam; a second layer of blended synthetic and natural latex; a third layer of memory foam; and a bottom layer of high-resilience polyfoam. The support core is constructed from high-density polyfoam, and the cover is a cotton blend.


  • Customers report that Casper mattresses produce little to no noise, and also significantly reduces (but does not eliminate) motion transfer.
  • The mattresses are relatively lightweight, making them easier to rotate as recommended.
  • Customers report that Casper offers responsive, helpful customer service, and the company does not charge shipping fees for deliveries or returns.
  • The price-point for The Casper and The Essential is bel0w-average compared to other memory foam models.


  • Compared to mattresses with comfort layers made entirely of memory foam, Casper mattresses — which feature both memory foam and polyfoam in the comfort layer — have received average to below-average customer ratings for motion isolation and conforming abilities.
  • Some reviews indicate the mattress sleeps hot (despite marketing claims suggesting otherwise), and weak edge support is another common complaint, particularly among owners that weigh 230 lbs or more.
  • Casper was founded in 2013, and the long-term performance of The Casper mattress has not been accurately assessed; additionally, The Wave was and The Essential were introduced in 2017. 
  • The price-point for The Wave is above-average compared to other memory foam models.

Sleep Trial and Warranty Information

Trial Period and Guarantee: Casper offers a 100-night, risk-free sleep trial.

  1. Within 100 nights of original purchase, owners may elect to return the mattress and receive a full refund, including shipping fees. Casper will arrange for couriers to come pick up the mattress from the owner’s home, at which time it will either be recycled or donated to charity.
  2. Please note: Casper mattresses purchased on must be returned to Amazon within 30 days of the original purchase.

Warranty: Casper offers a 10-year nonprorated warranty for all mattresses:

  1. Warranty coverage kicks in on the original purchase date
  2. The 10-year limited warranty will only be provided to customers who purchase their mattress directly from Casper or an authorized seller of Casper products.
  3. During the warranty coverage period, Casper will replace or repair a defective mattress. Casper will cover fees for returning a defective mattress to the company, but the owner will be required to pay fees for having a replaced or repaired mattress shipped back to them.
  4. Mattress owners must pay the difference if their defective mattress is replaced with an upgrade model.
  5. In the event that a defective mattress is repaired or replaced with the same mattress model, the original warranty coverage will continue. If the mattress is replaced with an upgrade, then a new warranty will be issued beginning on the date that the upgrade is purchased.
  6. The warranty will be voided if the owner uses the mattress for something other than its intended purpose. It will also be voided if the owner does not provide a proper foundation to support the mattress. According to Casper, proper foundation options include the following:
    • A foundation and modern box spring with wooden slats that are no more than 4″ apart.
    • A flat platform bed.
    • A slatted base made of wood with slats that are no more than 4″ apart.
  7. A Casper mattress warranty covers the following product defects:
    • Indentations in the foam that are 1″ or deeper that do not result from improper foundational support.
    • ‘Any physical flaw’ that causes the mattress to split or crack beyond normal wear and tear.
    • Manufacturing defects that affect the cover zipper.
  8. The warranty will not cover the following:
    • ‘Normal increase in the softness’ of the comfort layer that does not affect its ability to alleviate pressure.
    • Replacements or repairs due to changes in the owner’s sleep preferences.
    • Burns, cuts, tears, liquid damage, stains, and other forms of damage that do not occur during manufacturing or shipping, and are directly caused by the owner or someone else using the mattress.
    • Replacement of other components of the Casper sleep system unless they are also defective.
    • Any mattress that has not been purchased directly from Casper or an authorized seller of Casper products.
  9. The warranty is only available to the original purchaser of the mattress. Anyone who purchases or acquires this mattress second-hand does so ‘as is’, and will not receive warranty coverage from Casper.

Casper Mattress Sleep Ratings

CategoryCriteriaCasper RatingWhat Casper Users Say
Customer SatisfactionBased on data collection, this is an overall customer sentiment regarding the Casper mattress.72% (All Three Models)Casper has earned an average satisfaction rating, due to mixed reviews regarding mattress performance and inaccurate or misleading product marketing.
Durability Memory foam is engineered to provide a comfortable, conforming sleep surface that retains its original shape over time, but indentations are to be expected.GoodOwners report that Casper models perform fairly well after long-term use, but the company has only been in business for three years, and the Essential and Wave models are less than a year old; as a result, the long-term performance of these mattresses has not been accurately assessed.
Motion IsolationMemory foam mattresses have been touted for superior motion isolation, which means that motion does not occur throughout the mattress when someone gets up or shifts their position.FairOwners indicate that The Casper and The Wave mattresses isolate motion to some extent, but not as effectively as comparable foam mattresses. The Essential isolates motion to a much lesser extent. 
Sex Many memory foam users report that these mattresses are not very conducive for sex due to the lack of responsiveness, which can create a feeling of ‘fighting’ the mattress.FairCasper mattresses on the whole have a little more bounciness that those with comfort layers made entirely of memory foam, but sinking and fighting feelings have been reported by some owners of The Casper and The Wave mattresses. 
ConformingMemory foam mattresses are engineered to conform to the sleeper’s figure, creating a cradle-shaped impression that aligns the spine and targets pressure points.GoodCasper mattresses feature a tiered comfort layer designed to balance firmness and contouring, but owner reviews indicate other mattresses — such as pure memory foam and latex models — conform closer and alleviate more pressure. The Essential offers below-average conforming compared to the other two Casper models.
Temperature NeutralityMemory foam retains more body heat than other mattress materials, and users often ‘sleep hot’ as a result.FairCasper mattresses are advertised as ‘sleeping cool’, but and above average number of owners report high levels of heat retention that cause them to sleep uncomfortably warm.
Off-gassingSome mattresses emit particles when they are unpackaged, accompanied by unpleasant ‘off-gassing’ smells that can last for days.FairOwners report moderate off-gassing with Casper mattresses and smells dissipating within a few hours to a few days after unboxing.
Edge SupportBecause of their construction, memory foam mattresses often feature little to no edge support.FairSimilar to other foam mattresses, Casper owners report issues with sinkage with sitting or sleeping close to the edge.
NoiseMemory foam mattresses create little to no noise, due to their lack of springs, coils, and other metal componentsExcellentAccording to owners, Casper mattresses produce virtually no noise when bearing weight.
Ease of Moving and RotatingMemory foam mattresses tend to be lighter, which makes them easier to move. They never need to be flipped, since only one side is designed for sleeping.Very GoodThe Essential and The Casper mattresses both weigh less than 75 pounds, making them relatively light compared to other memory foam models; The Wave, on the other hand, weighs more than 100 pounds.
