Saatva vs Casper US: Comparing Construction
Both mattresses have five layers, with significant differences in construction. Comparing the layers can help you determine which innerspring hybrid is more likely to meet your needs.
Top Layers
Casper has a soft, airy knit blend cover with added height for a cozy feel. The Saatva Classic has a 3-inch breathable Euro pillow top with Lumbar Zone® Quilting for more support in the center third where needed the most.
Middle Layers
Both mattresses have zoned support layers and breathable materials. Saatva’s Classic has patented Lumbar Zone® Active Spinal Wire with a gel-infused memory foam lumbar crown for pressure relief and heat dispersion. Casper’s layer of open-cell polyurethane foam improves mattress airflow.
Get extra support in the body’s middle area with the Classic’s layer of Lumbar Zone® coils, which are stronger in the center third of the mattress. The individually wrapped coils, made from 14.5-gauge recycled steel, cradle pressure points to help relieve tension.
Casper’s mattress uses precisely cut foam channels to offer pressure relief and support in the area beneath the waist, hips, and lower back, and a memory foam layer cradles the body’s curves. An added feature of Saatva’s Classic is the high-density foam rails for firmer edge support to increase sleep surface and ease of getting in and out of bed.
Bases
Both mattresses have independent-moving coils at the base. This design is known to support healthy spinal alignment and breathability. With two coil layers in total, the Saatva Classic offers extra mattress durability and airflow for cooler sleep.
How Do Sizes Compare?
Saatva’s Classic Mattress is available in two additional sizes to Casper (twin and split Cal king). The Classic comes in all these standard US sizes:
- Twin
- Twin XL
- Full
- Queen
- King/Split
- Cal King/Split
The Saatva Classic has two height options:
Having a choice of heights is great for those who want to customize the look of their mattress. Split Cal king is the exception; it is 11.5 inches. Casper does not have height choices; it is 14 inches.
What about Firmness and Sleep Style?
Casper is medium-soft, with zoned support and precisely cut foam channels to suit various sleep positions. Rather than only having one choice, Saatva offers three firmness choices for its Classic Mattress:
- Plush Soft
- Luxury Firm
- Firm
The softest of the three options, the Plush Soft is most comparable to Casper. Lighter individuals often prefer a soft mattress for contouring and comfort, while some side sleepers find pressure relief in sensitive areas like the hips and shoulders.
The Luxury Firm is a medium to medium-firm range, which several back sleepers prefer, as do some side, stomach, and combination sleepers. For couples with different preferred firmness levels and sleep styles, this range may be comfy for both partners. The Classic Mattress in Firm may suit certain back, stomach, and plus-size sleepers looking for additional support.

Saatva vs Casper: Pros and Any Drawbacks
Comparing the potential benefits and any limitations of the spotlighted mattresses can help you decide which most closely aligns with your sleep needs.
Zoned Support
Getting enough support in areas like the lower back, hips, and shoulders, where needed the most, may improve comfort for better sleep and help prevent morning soreness and stiffness. Both mattresses have zones to promote proper spinal alignment and offer targeted pressure relief in sensitive areas. Casper does so with precision-cut channels in the foam, while Saatva uses patented quilting and coils to support the lumbar (lower back) area.
Added lumbar support may help some people with back pain sleep comfier. Strong back support has helped the Saatva Classic Mattress earn recognition from chiropractor groups. The American Chiropractic Association (ACA) rigorously tested the mattress for spinal support before endorsing it. The premium mattress also has a Congress of Chiropractic State Association Seal of Approval. Casper’s Dream Max has neither endorsement, although its zoned support encourages proper spinal alignment.
Pressure Relief
Zoned support helps reduce pressure point buildup for certain sleepers, making for greater comfort and potentially better sleep. The dual-coil design of Saatva’s Classic Mattress contours the body’s curves, adapting to your unique shape and sleep style to relieve pressure. Casper also has coils that move independently, although it’s a single layer.
Motion Isolation
While both mattresses get high ratings online for motion isolation, some people find that having more foam, like the Casper mattress, can isolate movement better. That lowers the chances of feeling a sleep partner tossing and turning, helping some couples get uninterrupted sleep.
Built to Order
Saatva mattresses are crafted in the USA and made to order. Each one undergoes a strict quality inspection before shipping. These details show a commitment to quality and customization. The Casper mattress is not made to order but is designed and assembled in the United States. Both brands include internationally sourced materials in the mattresses.
Luxury Comfort
Both mattresses use top-quality materials for a more luxurious feel. The Saatva Classic has a thick yet breathable Euro pillow top, and Casper has a soft, airy knit cover. The multiple foam layers in Casper’s medium-soft mattress give it a hug-like feel. That may feel comfortable to those who like sleeping on an all-foam mattress but want more support.
The Saatva Classic has three comfort levels, depending on what the individual prefers. Plush Soft has a comforting, hug-like feel, and Luxury Firm offers a plush yet supportive feel without excess sinking. Firm has a more traditional innerspring feel that appeals to those who want to sleep on a mattress rather than sink into it. We like that sleepers have choices based on personal preference for comfort and support.

Cooler Sleep
Those who sleep hot may look for a cooler mattress. Both Saatva and Casper use breathable materials throughout the mattress layers to improve air circulation. Both have breathable covers. Open-cell foam helps prevent the Casper model from overheating. Saatva’s Classic has a second coil layer for added airflow.
Price
As luxury mattresses, neither one is the cheapest option available. Saatva’s Classic Mattress is a lower price than Casper. While it will not meet every household budget, the Saatva mattress is reasonably priced, given the premium materials and the opportunity for a luxurious sleep environment.
Sensitive Individuals
The foam in the Saatva Classic is CertiPUR-US® certified. The foam is free of formaldehyde, ozone depleters, phthalates, specific flame retardants, and heavy metals like lead. CertiPUR-US® foam is low in VOCs (volatile organic compounds), reducing a slight scent common with new foam, called off-gassing. Also, the Classic Mattress is GREENGUARD® Gold certified for low chemical emissions.
Casper’s model does not have these certifications, which may be important to those with sensitivities. Both mattresses are fiberglass-free, helping sleepers avoid fiberglass-related issues, such as sneezing. In addition, the Classic Mattress has a hypoallergenic cover with Saatva’s exclusive Guardin™ botanical treatment to combat bacteria, mold, and mildew growth.
Saatva vs Casper for Shipping, Sleep Trial, and Warranty
Shipping
Free white glove delivery across the continental US comes standard with Saatva mattresses. The company’s delivery team sets the mattress up in your chosen room and offers free mattress removal based on its policy.
Casper ships its mattress free across the 48 contiguous US states, with an extra fee to Alaska or Hawaii. The in-home delivery and setup service is an additional fee, with a mattress removal option. While Saatva does not ship directly to Alaska or Hawaii, its team can help you coordinate delivery via a freight forwarder, per the US site.
Sleep Trial
Saatva and Casper both include sleep trials with their mattresses, although Saatva offers a longer one. Saatva is 365 nights from the delivery date, and Casper is 100 nights. Sleeping on the mattress longer gives you more time to decide if it’s right for you.
In the unlikely case that you want to return the mattress within the trial period, both companies offer a full mattress refund, based on their applicable policy, with a few differences. Saatva has a $99 processing fee for pickup, and Casper has a 30-night adjustment period before starting a return.
Warranty
Saatva US includes a generous lifetime warranty with the Classic Mattress, covering material and workmanship defects for as long as you own it as the original purchaser. Casper includes a 10-year limited mattress warranty with its mattress for the original purchaser, covering specific defects. Reading a warranty policy for repair and replacement details can improve understanding of buyer protections.
Comparing Saatva vs Casper: Conclusion
When looking for a supportive luxury mattress, comparing leading brands can provide insights into which one most aligns with your needs. Both spotlighted mattresses offer zoned support to promote spinal alignment and pressure relief, but their construction differs in significant ways.
Saatva’s Classic Mattress stands out with its three firmness options and two height choices, giving sleepers more ways to customize comfort and style. It also has a breathable Euro pillow top, dual coil layers, and Lumbar Zone® Technology designed to support the lower back.
