Saatva and Casper are two of the most recognized names in the online mattress world, but they offer fundamentally different sleep experiences. Saatva’s flagship is a classic innerspring hybrid with a plush pillow top, while Casper built its brand on balanced all-foam and hybrid models. Deciding between them comes down to core preferences on feel, firmness, and construction. This guide breaks down the key differences to help you choose the right mattress for your sleep style and budget.

Saatva vs. Casper At a Glance

Construction and Materials

The biggest distinction between these two brands lies in their core construction. One is a classic hybrid, the other features modern foam layers.

Saatva Classic

The Saatva Classic is a luxury hybrid innerspring mattress built with a “coil-on-coil” system. It starts with a base layer of tempered steel support coils for durability and airflow. On top of that sits a second layer of individually pocketed coils that respond to your body’s curves to provide targeted support and reduce motion transfer. The comfort system includes a plush Euro pillow top, providing a cushioned surface over the responsive springs. The entire mattress is wrapped in a breathable organic cotton cover.

Casper Original & Wave Hybrid

Casper offers both all-foam and hybrid constructions. The popular Casper Original features three zones of targeted support, with softer foam under the shoulders and firmer foam under the hips, waist, and lower back to encourage spinal alignment. Its top layer is a perforated foam designed for breathability. The Casper Wave Hybrid advances this concept with “Zoned Support Max,” using gel pods under the waist and lower back for even more targeted support. Both Casper models aim for a balanced foam feel that avoids the quicksand sensation of traditional memory foam.

Firmness, Feel, and Sleeper Types

Saatva offers more customization with three firmness levels, while Casper focuses on a universal, medium-firm feel.

The Saatva Classic comes in Plush Soft (around a 3/10), Luxury Firm (6/10), and Firm (8/10). The Luxury Firm is the most popular, providing a balance of contouring and support suitable for most back, side, and combination sleepers. Its coil-on-coil design gives it a responsive, buoyant feel where you sleep “on” the mattress rather than “in” it. Strict side sleepers often prefer the Plush Soft, while stomach sleepers and heavier individuals may need the Firm option.

The Casper Original has a medium feel, typically rated around 5/10 on the firmness scale. The Wave Hybrid is slightly firmer, closer to a 6/10. Both mattresses have a gentle, conforming feel. The foam adapts to your shape to relieve pressure points, but it’s responsive enough to prevent feeling stuck. This balanced profile works well for side and back sleepers, though some stomach sleepers may find their hips sink a bit too much on the all-foam Original.

Performance Features

Cooling

For those who sleep hot, the Saatva Classic has a clear advantage. The dual layers of innerspring coils allow for significant airflow throughout the mattress, pulling heat away from your body. Casper’s perforated foams and breathable covers are designed to mitigate the heat retention common in all-foam beds, but they cannot match the airflow of a coil-on-coil system.

Edge Support

Saatva excels here. The perimeter of the Classic is reinforced with a high-density foam encasement, creating very firm and stable edges. You can sit or sleep near the edge without feeling like you might roll off. Casper’s mattresses, particularly the all-foam Original, have softer edges that compress more under weight. The hybrid models offer better edge support than the foam version, but they still don’t feel as robust as the Saatva.

Motion Isolation

This is where Casper shines. The foam layers in the Original and Wave Hybrid are excellent at absorbing movement, so you’re less likely to be disturbed by a restless partner. While Saatva’s pocketed coils are much better at isolating motion than older innerspring designs, some movement can still transfer through the spring system. Couples who are very light sleepers will likely prefer Casper.

What You’ll Actually Pay

Saatva’s pricing for its Classic model is generally in the premium range, often starting around $1,300 for a Queen and going up. The Casper Original is more affordable, sitting in the competitive $1,000 to $1,500 range. The Casper Wave Hybrid is a luxury option, often priced significantly higher than the Saatva Classic. Remember to check for current pricing and promotions.

An important distinction is delivery. Saatva includes free white-glove delivery, where they set up the new mattress and remove your old one. Casper ships its mattresses compressed in a box and delivery to your door is free, but in-home setup is an additional fee.

• Saatva Classic (Queen): Typically in the ~$1,800 – $2,200 range. Includes white-glove delivery and mattress removal.
• Casper Original (Queen): Typically in the ~$1,200 – $1,500 range. Arrives in a box.
• Casper Wave Hybrid (Queen): Typically in the ~$2,500 – $3,000 range. Arrives in a box.

Which Should You Buy?

Your choice depends heavily on your preferred mattress feel and primary needs.

• If you want firmness options and a traditional feel: Go with Saatva. Its three firmness levels, responsive coil support, and durable edges make it a versatile choice for almost any sleeper who prefers a classic innerspring bounce.
• If you are a side sleeper or prefer a foam hug: Choose Casper. The Original’s zoned support foam is excellent for relieving pressure on the shoulders and hips, and both models excel at isolating motion.
• If you sleep hot or need strong edge support: Saatva is the clear winner. Its coil-on-coil construction provides superior airflow and a reinforced perimeter.
• If you want to try a mattress in San Diego: You can test the Saatva Classic in person at our Yawnder showroom in Encinitas. Casper does not have a showroom in the area.

Frequently Asked Questions

Do Saatva and Casper mattresses need a box spring?

The Saatva Classic can be used with a box spring if it is in good condition, but a platform base or slatted foundation works just as well. Casper mattresses are designed for a firm, flat surface and should not be used with a box spring; a platform or slatted base is ideal.

How long are the sleep trials and warranties?

Saatva offers a 365-night sleep trial and a lifetime warranty. Casper offers a 100-night trial and a 10-year limited warranty. Always confirm the latest details on their websites before purchasing.

Which mattress is better for heavy people?

The Saatva Classic, particularly in the Firm model, is generally a better option for individuals over 230 pounds due to its dual-coil construction providing more durable support. For even more robust support, Saatva also offers the Saatva HD mattress designed specifically for heavier sleepers.

Does Casper smell? Does Saatva smell?

Casper mattresses, being foam and shipped in a box, may have a slight “off-gassing” odor upon unboxing that typically fades in a day or two. The Saatva Classic is not compressed in a box and uses materials with minimal off-gassing, so it arrives with virtually no smell.

Bottom Line

For shoppers seeking a premium, durable mattress with customizable firmness and a traditional feel, the Saatva Classic is an outstanding choice. Its superior edge support, cooling, and free white-glove delivery provide excellent value. For those who prefer the gentle contouring of foam, prioritize motion isolation, and are primarily side or back sleepers, the Casper Original and Wave Hybrid are strong contenders. Given its innerspring construction and multiple firmness options, Saatva is the more versatile mattress that will suit a wider variety of sleepers.
