Casper and Tempur-Pedic are two premium mattress brands with a range of choices for their buyers. Casper is fairly new on the market, having started selling mattresses only since 2014. Tempur-Pedic, on the other hand, has been around since 1992 and is often considered the ultimate heavyweight when it comes to premium mattresses.
Despite the major age gap between these brands, lots of buyers struggle to choose between Casper vs Tempur-Pedic since they both offer impressive selections. For the sake of this comparison, we’ve chosen mattresses from each brand that are most similar based on their features and what consumers are looking to get from them to give you the fairest review.
We’ve collected data for the Casper Sleep Mattress and the Tempur-Pedic TEMPUR-Adapt Foam Mattress to give you a definitive comparison and help you make the right choice. Discover what we learned here and finally put a lid on the great Casper vs Tempur-Pedic debate.
Casper is a US-based sleep products company that’s been around for about 5 years. The brand’s flagship mattress – the Casper Sleep Mattress – is one of its best releases yet, and it has recently been updated to a 12-inch height for increased comfort. However, they have had a number of other design winners, like the Wave Model which has made ripples as a contender for best mattress around the web.
The Tempur-Pedic brand has been around for nearly 3 decades and is known as a premium mattress and sleep products brand. Some of their prime choices include the Tempur-Pedic Flex Prima Mattress and the Contour Collection.
Both brands are contenders for best mattress, which is why they’re frequently pitted against one another in Casper vs Tempur-Pedic comparisons.
The Casper Sleep Mattress and the Tempur-Pedic TEMPUR-Adapt Foam Mattress are particularly similar, making it all the more difficult for consumers to choose a new mattress. Both mattresses are available in similar sizes, weights, and construction. However, there are discrepancies with their comfort core.
4-layer memory foam construction
Open-cell hypoallergenic Latex
Shoulder foam designed for comfort, supportive foam in the core and hip region
Both mattresses from Capser and Tempur-Pedic use Polyfoam support cores which essentially increase the firmness of the mattress to result in proper spine alignment. This relieves pain and discomfort during sleep so that you can wake up feeling refreshed and well-rested.
The differences between the mattresses are most apparent with the comfort and cover layers. The Casper Sleep Mattress uses a combination of three different foam types for its comfort layer. The bottom layer of 1.5” latex-like foam provides just the right levels of support, whilst staying comfortable for the body. Essentially, this layer is what responds to pressure, allowing some bounce and cradling your body weight so that it doesn’t sink into the foam.
The second layer of 1.5” 4 PCF memory foam works against pressure, softly holding your body weight so as to reduce pain and discomfort on bony prominences. The last, top-most layer of 1.5” open-cell polyfoam aims to cool the mattress, releasing trapped air so you can enjoy a comfortably cool night’s rest.
On the other hand, the TEMPUR-Adapt mattress features the TEMPUR-ES Comfort Layer – a soft memory foam layer that aims to create the perfect balance between comfort and support. On top, the mattress features a cool-to-touch SmartClimate Dual-Layer removable cover. Boasting premium knit technology, this removable layer lets out heat to maintain a comfortable mattress climate that regulates the production of sweat.
‘Comfort’ is a relative term that changes from user to user. To give you a better, more definitive idea of how these mattresses perform in terms of the comfort they offer, we’ve broken down the comfort section into different factors
Firmness and support
The ideal mattress should combine just the right firmness in order to properly support your body weight. Mattresses that are too soft won’t only let you sink into their foam, but might also prevent optimal spinal alignment during sleep. Holding such a position for extended periods could cause the development of chronic back pain and other similar conditions.
The Casper Sleep Mattress is slightly softer than it is firm, providing a little more ‘give’ to accommodate your weight as you relax into the foam. It uses a 7” support core versus a 4.5” comfort core, which is a relatively close ratio compared to other mattresses. This lets the mattress compress comparatively more, as though hugging you as you sleep.
The TEMPUR-Adapt mattress is likewise softer than it is firm, but the memory foam layer is slightly less dense than the Casper’s comfort core. For that reason, the TEMPUR-Adapt may provide more support during sleep, preventing the foam from compressing too much, and thus keeping your spine in proper alignment throughout the night.
Both mattresses have taken the necessary steps to combat heat, incorporating features that aim to release pent up warmth to cool down the layers. The Casper Sleep Mattress uses a breathable open-cell foam layer to top off the entire construction. With its porous structure, the layer helps make heat escape to help keep you cool and comfortable. The entire mattress is enveloped in a polyester cover that also helps release heat.
The TEMPUR-Adapt mattress offers slightly more intuitive cooling technology. The Cool-to-Touch Premium Knit Technology cover works more effectively compared to the plain polyester cover used by Casper’s Sleep Mattress. Plus, the TEMPUR-Adapt mattress also features a SmartClimate Dual Layer that efficiently encourages the exchange of hot and cool air to keep the mattress well-ventilated and free from pent-up heat.
If you sleep next to a restless partner or if you co-sleep with your kids, then you probably already know how important it is to have a mattress that ranks low on the motion transfer scale. Essentially, this means that any movement that occurs on one side of the mattress is kept isolated, preventing you from having to feel the constant tossing and turning of other you share your bed with.
In this respect, the TEMPUR-Adapt and Casper Sleep Mattress differences become far more apparent. The TEMPUR-Adapt mattress features a low motion transfer rating thanks to its premium support layer that absorbs vibrations and movement to give you a more peaceful sleeping experience.
The Casper Sleep Mattress on the other hand, doesn’t isolate motion quite as well. That’s mostly due to its slight bounce, which was developed to support intimate activity. Nonetheless, it still performs better than most inner spring mattresses when it comes to limiting the transfer of movement over its surface.
Responsiveness refers to how quickly a mattress responds to any changes in pressure across its surface. Mattresses that respond more readily to pressure changes are often preferred because they keep spinal alignment in check as you shift and move throughout the night. If a mattress can’t expand or depress readily to your movements, then your body will be forced into positions and postures that might do harm to your muscles, joints, and bones.
The Casper Sleep Mattress features more advanced memory foam technology that performs better than older foam mattress designs. This means that the layers will respond more readily to shifting weight, providing you excellent support. On the downside, this high level of responsiveness also has an impact on bounce. This is what makes the Casper mattress less capable of isolating movements, thus causing disturbance to other sleepers who share the bed with you.
The TEMPUR-Adapt demonstrates excellent responsiveness, shifting against pressure changes almost instantly. The mattress also returns to its original shape and density within moments after the pressure is removed, which helps to keep your spine and body in proper alignment throughout the night.
Resilience and bounce
There are some individuals who prefer a particularly bouncy bed, especially because it supports optimal intimate activity and performance. Bounce also helps ease the process of shifting positions, letting you move from side lying to back to stomach positions by ‘bouncing’ your weight off of the bed to achieve a little airtime.
In the Casper vs Tempur-Pedic debate, the Casper Sleep Mattress takes the cake in the bounce department. Although far less bouncy than most inner spring mattresses, the Casper Sleep Mattress does respond well to forceful pressure. Of course, that also means that the mattress may not be able to isolate the motion cause by the bounce, nonetheless, it can be ideal for some buyers.
The TEMPUR-Adapt mattress is far less bouncy, although still accommodates quick position shifting with its soft top layers. In terms of supporting intimate activity, it doesn’t dampen movement and still lets you gain leverage by providing ample support that keeps you and your partner from sinking too deep into its surface.
Some mattresses only offer support around the central surface area. As your body shifts and moves at night towards the edges of the foam, the topography might change, causing sagging along the outer edges of the mattress and thus a lack of support. You’ll notice that a mattress has poor edge support if you sit on the borders and feel the need to dig your heels into the floor in order not to fall off.
Casper mattresses in general do not use edge support technology since the brand is dedicated to providing you support for sleeping – not sitting. That said, you might notice some sagging when applying weight to the edges of your Casper Sleep Mattress. Is it a deal breaker? Not really. But you might have to clench your body slightly to maintain balance when you sit or sleep on the edge.
For edge sleepers, the TEMPUR-Adapt might be a better choice. The mattress uses a light, breathable, and slim edge support structure that’s far less robust than what you would see on inner spring mattresses. Of course, being that it is a foam mattress, it does still sag slightly more than a structured spring mattress, but it offers far more edge stability than the Casper Sleep Mattress.
Inflation time, off-gassing and smell
The TEMPUR-Adapt mattress is shipped as is, in an air-tight, sealed, dense plastic cover that keeps it slightly compressed throughout the delivery process. Once unpacked, the mattress will inflate slightly to achieve its actual form and density. In terms of its odor, the TEMPUR-Adapt mattress will unpack with a chemical smell which comes from the adhesives used for the foam inside. Off-gassing can take up to 1 week or longer, depending on your sensitivity to the odor that it emits.
The Casper Sleep Mattress may require a slightly longer period for inflating and off-gassing. Casper products comes packaged in a small box a fraction of the size of the mattress itself, which will require that you unpack and set out the mattress between 24-48 hours for it to expand to its actual size and shape.
In terms of its smell, the Casper Sleep Mattress has a far stronger chemical odor because of its packaging. Some buyers have complained that it could take a month or more to complete the off-gassing process.
Sleep position ratings
(less than 130 lbs)
(130 lbs to 230 lbs)
(greater than 230 lbs)
*Out of 10
The sleep position ratings for both mattresses are nearly identical. Both perform well for light and average weighted sleepers, with slightly lower ratings for stomach sleepers. The main difference lies in the rating for heavier sleepers greater than 230 lbs, for which the Tempur-Pedic mattress definitely outperforms its Casper competitor.

The Sleep Trial is offered by most brands selling sleep products, letting buyers experience their mattress for a few weeks or months before deciding on whether or not they want to proceed with their purchase.
The Casper Sleep Mattress offers a 100-night sleep trial period during which you can adjust to your new mattress and determine whether it suits your sleeping preferences. The item can be returned free of charge within the 100-day period.
The TEMPUR-Adapt mattress comes with a slightly shorter sleep trial at 90 nights which may be more than enough for you to adjust and adapt to your new mattress to make a decision on whether or not it suits your preferences.
Warranty and refund
Both mattresses offer a 10-year limited warranty that covers manufacturer defects and malfunctions. Any parts of the mattress that manifest defects or damages due to manufacturer error are eligible for free repairs and replacements.
The Casper and Tempur-Pedic mattresses both offer free refunds within the sleep trial period, reimbursing the full cost that you spent as long as you place your request for refund within the sleep trial period.
The Tempur-Pedic mattress is delivered in an air-tight, vacuum-sealed plastic and packaging. The mattress arrives in its full size and can be shipped within all 50 US states. The Casper mattress, on the other hand, arrives in a much smaller box, about half human height. These mattresses can be shipped anywhere in the US and Canada.
Neither of the two brands allow buyers to trade-in old mattresses for a reimbursement or discount on a new mattress purchase. However, it is worth mentioning that the Casper brand lets you have your old mattress removed with White Glove delivery without any extra charge. The offer doesn’t apply to standard delivery.
