The classic innerspring mattress dominates the sleep market, and for good reason. It has the springy, responsive quality that, for many people, is what a mattress should feel like. Today, many innerspring mattresses feature a coil base topped with another material such as memory foam. The category is known as a hybrid mattress, and it’s increasingly popular because it combines the responsiveness and support of innersprings with the contouring comfort of memory foam.

Saatva Classic Innerspring
Our flagship luxury mattress is expertly engineered with coil-on-coil construction for durability, a layer of memory foam for enhanced back support, and a cushiony Euro pillow top for extra comfort.
Here, we break down the key differences between two leading hybrid mattresses: the Saatva Classic and the Casper Hybrid.
Comfort is a tricky thing. What feels good to one person may not feel all that great to another. Most manufacturers place their “comfort levels” on a numerical scale, with 1 being the softest and 10 the firmest—though it’s important to note that no two manufacturers’ scales are exactly the same. Overall, what makes one hybrid mattress more comfortable than another is a function of the type of springs, how they are arranged, and the materials and construction of other layers in the mattress.
Do I have a choice of comfort levels?
Saatva Classic: Yes (plush firm, luxury firm, and firm)
The bottom line: More comfort levels equals more chances for you to find your best mattress match. The Saatva Classic hybrid comes in three comfort levels: plush firm (the softest), luxury firm (medium), and firm. The Casper Hybrid comes in one comfort level option, medium-firm.
What kind of springs are in the mattress?
Saatva Classic: A “coil on coil” system, consisting of a steel coil support base, plus a second unit of individually wrapped comfort coils
Casper: Individually wrapped coils
The bottom line: The most important feature when it comes to the performance of a hybrid innerspring mattress is—surprise!—the springs. The Saatva Classic is made with “coil on coil” construction. A steel coil support base, made with tempered, recycled steel, provides durability and resistance to sagging. A second layer of individually wrapped comfort coils in the top portion of the mattress adds contouring ability and reduces motion transfer (so one bed partner isn’t jostled when the other shifts position or gets up during the night). Both sets of coils are encased in foam for increased edge support, better durability, and more sleep surface.
The Casper Hybrid also features foam-encased coils that provide contouring support and minimize motion transfer. The biggest difference between the two brands is that the Casper Hybrid contains only a single layer of coils.
What kind of lumbar support does the mattress have?
Saatva Classic: Patented Spinal Zone active wire and a ½-inch layer of memory foam in the lumbar region
Casper: Firmer foam in the center third of the mattress
The bottom line: Both mattresses offer extra lumbar support in the center third, where most people’s body weight is concentrated. The Saatva Classic takes a two-pronged approach to lumbar support. The first is a patented Spinal Zone active wire that strengthens the center third of the bed to ensure this part of the mattress is firmer. The second is a layer of memory foam in the lumbar region to add pressure relief for the low back and help maintain healthy spinal alignment. The Casper Hybrid has an area of firmer foam in the center third. (Here’s how to find the best mattress if you suffer from back pain.)
What does the mattress do to keep you cool?
Saatva Classic: Breathable organic cotton and Certi-PUR-US®-certified foam
Casper: Breathable foam
The bottom line: Hybrid mattresses naturally sleep cool because innersprings allow for easy air flow. Additionally, the Saatva Classic features breathable organic cotton in its cover and cooler-sleeping eco-friendly foam with a more open-celled structure than traditional foam. Casper describes its foam as breathable.
You’re going to be spending a lot of time—and money—on your mattress, so you want one that’s built to last. Beyond mere comfort, you’ll need to consider the factors that affect mattress quality and longevity, such as coil thickness, edge support, and eco-friendly materials.
What is the coil gauge?
Saatva Classic: 13 gauge in the support layer of coils, 14.5 gauge in the top layer of coils
Casper: The company does not disclose coil gauge.
The bottom line: Coils come in different thicknesses, known as gauge. The higher the gauge number, the thinner and more flexible the coil. The lower the number, the thicker and more supportive. A premium mattress should have a coil gauge between 12 and 15. Saatva’s base layer of coils is made of thicker tempered steel for durability; the individually wrapped comfort coils are thinner and more flexible so they can respond and contour.
Casper does not disclose the coil gauge of its hybrid mattress, which like Casper all-foam mattresses is designed to be compressed, folded, and rolled to fit into a shipping box. For coils to provide optimal spinal support, they need to be strong and durable—but we believe that strong, durable coils can’t be easily compressed.
What kind of edge support does the mattress have?
Saatva Classic: Foam-encased coils
Casper: Foam-encased coils
The bottom line: Edge support makes it possible to sit or lie on the edge of the bed without the mattress collapsing. Saatva and Casper both use a foam border for solid edge support.
What is the flame retardant made of?
Saatva Classic: Natural plant-based thistle
Casper: Woven silica sock
The bottom line: When it comes to mattresses, toxic ingredients are most likely to turn up in fabrics and components treated with fire retardants, such as covers and foam padding. Saatva’s fire barrier is made from all-natural material—thistle pulp woven into a mesh—without the use of harmful chemicals. Casper uses a woven silica sock that does not contain any flame retardant chemicals.
Is the mattress cover organic?
Saatva Classic: Yes
The bottom line: The Saatva Classic mattress is covered in 100% organic cotton treated with Guardin®, a plant-based antimicrobial that inhibits bacteria and prolongs the life of the fabric. The main ingredient in the Casper Hybrid cover is polyester. (Here’s what you need to know about organic mattress components.)
When you’re buying a new mattress, cost is often one of the biggest factors. But to determine whether you’re truly getting the most for your money, look beyond what’s printed on the price tag to value-adds such as comfort guarantees, delivery policies, warranty terms, and customer service.
How much does the mattress cost?
Saatva Classic: $599 for a twin, $749 for a twin XL, $999 for a full, $1,099 for a queen, $1,499 for a king or Cal king
Casper: $745 for a twin, $845 for a twin XL, $1,245 for a full, $1,395 for a queen, $1,695 for a king or Cal king (at time of publication)
The bottom line: The Saatva Classic costs less than the Casper at every size. That means when you purchase a Saatva, you’re getting premium components like a strong, durable coil-on-coil base and breathable organic cotton at a significantly better price.
How is the mattress delivered?
Saatva Classic: Free white-glove delivery
Casper: Free shipping via UPS or $149 for in-home delivery and setup
The bottom line: Saatva does all the heavy lifting for you—from delivery and setup of the Saatva Classic mattress to the removal of your old mattress. The Casper Hybrid is delivered to the customer’s doorstep, but setup is your responsibility. A boxed queen-size Casper Hybrid weighs 106 pounds. Casper offers an in-home delivery and setup option for an additional $149.
How long is the risk-free trial period?
Saatva Classic: 120 days
Casper: 100 days
The bottom line: The best way to be sure if a mattress is right for you is to sleep on it for a while. With Saatva, you get an extra 20 days to decide. If you change your mind at any time during the trial period, Saatva will exchange it for another mattress or take it away for donation or recycling. In the case of a return, you are responsible only for a $99 transportation fee. Casper will arrange for returned mattress pickup through a local charity or recycling party at no extra charge.
How long is the warranty?
Saatva Classic: 15 years
Casper: 10 years
The bottom line: The Saatva non-prorated warranty period is five years longer. Here’s how it works: If a mattress is deemed defective during the first two years, Saatva will replace it with a brand new mattress, free of any charges. After that, the company will repair and recover the mattress for the cost of transportation ($99 each way). Casper offers a 10-year warranty and waives shipping costs associated with mattresses returned under the warranty.
