The Casper and Purple mattresses are often compared to each other due to the price similarity and brand recognition. However, the similarities tend to end here.
Casper’s been making mattresses for a lot longer than Purple and has a tried and true reputation for a great bed at a fair price.
Purple, on the other hand, made a huge splash upon arrival—with viral marketing campaigns, a proprietary design that’s only partially foam, and a bed that promises to feel like no other.
So is different better? Or will Casper beat flash with value and a better product? We’re going to take a look at both mattresses today—comparing features and specifications with overall value.
At the end, we’ll figure out which mattress does hold up.
$595 - $1,195
5 - 10 Years
The Casper is perfect for side-sleepers, those looking for a softer overall mattress, and those looking for a slightly cheaper offering.
$699 - $1,299
The Purple is perfect for those who shift positions during the night, need a cooler bed, or want the unique Purple experience.
Firmness and Support
Both the Casper and Purple mattresses are excellent choices for those who are looking for cradled pressure points and a bed that doesn’t swallow you whole during the night. How they accomplish this task, however, does vary.
The Purple mattress focuses on a special material called Hyper-Elastic Polymer that we’ll be getting into in a minute. Here’s the short of it—the material promises support where needed and firmness to keep you from sinking into the bed.
Thus far, the new material hasn’t been reported to have any issues with elasticity, and most adherents to the Purple brand love the unique feel of the bed. However, not everyone likes the feeling of sleeping on a grid, so we strongly recommend trying out a friend’s Purple mattress or taking advantage of the 100-day trial period offered by the company.
The Casper mattress uses layers of foam like many other bed-in-a-box offerings and aims to be more supportive as you sink deeper into the bed. This results in a bed that works pretty well for average body types—although this becomes an issue with sleepers outside of the bell curve.
Smaller sleepers may find the bed to be a bit too hard for comfort, and larger sleepers will probably feel too swallowed by the product and have difficulty tossing and turning during the night.
Your mileage will vary, but in the end? We’re giving this one to Purple. The material simply doesn’t change as much when you change the amount of weight on the bed. Large or small, thick or thin—the Purple mattress will always feel the same.
You’re going to notice a considerable improvement over a spring-based mattress by choosing either the Casper or the Purple—and both come very close to achieving the best isolation you can expect with a mattress.
The thick and four-layer foam build of the Casper means that there are a lot of places where movement can be absorbed. However, the plush feel of the Casper in comparison to Purple means that there’s a slight edge to be given to the Hyper-Elastic Polymer.
Purple beds—by design—are bouncier and quick to retain their original shape. You’re not going to see a night-and-day difference between the two beds, but if you’re going to go with one over the other precisely in the motion isolation department, the Purple wins again. There’s just no beating that fancy Purple grid.
Construction and Materials
Like we mentioned earlier, the Purple mattress is built with what the manufacturer is calling Hyper-Elastic Polymer. They’ve got a slick website and clear explanation here and promises that their material bounces back and keeps bouncing for many years and decades to come.
This grid system also provides a fair amount of coolness in comparison to the Casper and other all-foam mattresses—which is important to note if you tend to sweat in the night.
Casper mattresses come with a specific layer of foam that they’ve dubbed Zoned Comfort. Height and size depending, if you lay on the mattress as designed, you’ll be laying on firmer foam at the hips and softer foam at the shoulders. For side sleepers, the development gives Casper a major boost against Purple’s unique design.
Since not everyone is a side sleeper or will enjoy the feel of sleeping on a Purple, this one’s too close to call.
Off-Gassing and Smell
Foam mattresses have a reputation for smelling pretty terrible right out of the box—but Casper performs more admirably than most.
Casper provides a detailed explanation for any off-gassing and smells you experience on their website. You can expect any odor from your new mattress to fade away after a few days or so.
Unfortunately, the Purple fairs worse in this category by a long shot.
The foam in the Purple mattress causes the bed to suffer from the same off-gassing that you could expect with other mattresses, but the problems don’t end there. Due to the design of Purple’s proprietary grid, buyers are often surprised to find white powder hidden in the folds of their new purchase.
This problem is incredibly prevalent. Enough, in fact, to warrant Purple putting an explanation up online to inform buyers that the powder is non-toxic and won’t cause any issues to users. Since they’ve chosen a grid-like system, shipping a flattened bed requires power to keep the grid from sticking and causing issues upon arrival.
Still, the smell of the new foam is only amplified by the powder and smell of the Hyper-Elastic Polymer, so if off-gassing is a particular issue for you, waiting a few days before sleeping on your new purchase may be the wisest choice.
Both the Purple and the Casper mattresses offer a variation on their flagship products to keep prices down and allure prospective buyers to the product line. While Purple products cost more as a whole, the queen-size bed for both run at virtually the same price.
- Average Price of A Queen-sized Casper Mattress: $995
- Average Price of A Queen-sized Purple Mattress: $999
- Average Queen-sized Mattress Price (Foam): $860
Who Should Buy A Casper?
When it comes to Casper vs Purple, the mattress that’s right for you will depend on your sleeping habits and personal desires for a bed.
With the built-in Zoned Comfort feature and a softer feel overall, the Casper is better for side sleepers who need their pressure points cradled throughout the night. Similarly, if you like more of a sunken-in feel for your bed, the Casper is probably a better fit.
The Casper is also great for people that either don’t like the feeling of sleeping on a grid or perhaps prefer the feel of an all-foam mattress over anything else. The Casper also comes in cheaper offerings if you’re willing to venture for a different bed than the standard. There are many options and very few wrong answers here.

Who Should Buy A Purple?
The Purple bed—much like its advertising—is more for those looking for a unique sleeping experience. If sleeping on 15 patents worth of purple gel-like grid doesn’t sound like your cup of tea, we’d give the Purple a pass. For those that do love it, however—it’s hard to go back.
All that aside, those who shift positions multiple times during the evening will see better results in the Purple and its ability to retain shape almost instantly. If coolness during the night is another major point of contention for you, the Purple mattress is a great fit.
If you’re willing to put up with the initial smell and a premium price for higher-end models, it’s hard to go wrong with the Purple. If you'd like more information, read our review.
