The Best Casper Pillows For Side Sleepers, Reviewed
Casper Essential Cooling Foam Pillow
What We Like
- Firm memory foam provides consistent support for side sleepers.
- Cooling gel and breathable cover help regulate temperature.
- Contouring shape aids head and neck alignment.
- Machine-washable cover simplifies maintenance.
Trade-offs
- At 5 inches high, it may be too thick for some.
- Firm feel may not suit those preferring a soft pillow.
A firm, 5-inch profile of memory foam gives side sleepers the consistent loft they need for proper spine alignment night after night. The cooling gel layer and breathable cover work together to pull heat away, which is a relief if you tend to sleep hot. This combination of reliable support and temperature management makes it a straightforward, no-fuss choice that delivers on core promises.
This pillow uses a solid memory foam core designed for side sleepers, which provides consistent firm support and proper neck alignment without needing adjustment. Unlike pillows with shredded or adjustable fill, its fixed shape means you cannot customize the loft. Reviewers report that the foam and cooling cover work together to allow decent airflow, making it a straightforward choice for hot sleepers who want a firm, set-it-and-forget-it feel.
Casper Hybrid Snow Pillow
What We Like
- Sleeps cooler for 12+ hours with Snow Technology
- Foam layers ensure shape, no fluffing needed
- Removable cover makes for easy care
- Balanced feel suitable for all sleep styles
Trade-offs
- At 6 pounds, it's heavier than the 3.5-pound Original Pillow
The Casper Hybrid Snow Pillow uses Snow Technology to sleep cooler for 12+ hours, a clear advantage for anyone prone to overheating at night. Its foam layers and fiber core create a balanced feel that holds its shape, so no fluffing is needed, and the design is noted as ideal for side sleepers. This combination makes it a focused choice for prioritizing temperature regulation.
The trade-off is in the profile. At two inches tall, it offers a notably lower loft than something like the Casper Essential Cooling Foam Pillow. While great for keeping cool, that lower height might not provide enough lift for side sleepers who prefer a more pronounced cradle for their head and neck. It’s a focused solution, sacrificing some plushness for its advanced cooling performance.
Casper Original Pillow
What We Like
- Pillow-in-pillow design adapts to head and neck movements
- Breathable cotton cover aids temperature regulation
- Machine washable and designed to resist clumping
Trade-offs
- Two-inch height is a medium loft
- Weighs 3.5 pounds
Its down-alternative fill adapts to your movements, making the Casper Original Pillow a versatile choice for people who shift between side, back, and stomach positions. This pillow-in-pillow construction pairs a supportive inner core with a softer outer layer for gentle contouring. A 100% cotton percale cover promotes airflow to help regulate temperature, and the entire pillow is machine washable for easy care.
With a height of two inches, this pillow offers a medium loft. For side sleepers who prefer a firmer, higher support, the Casper Essential Cooling Foam Pillow provides a five-inch profile. The Original’s strength lies in its adaptability across all sleeping styles.

Casper Hybrid Pillow
What We Like
- Balanced foam and fiber feel all night
- Consistent shape requires no fluffing
- Removable cover for easy care
- Supportive profile ideal for side sleepers
Trade-offs
- Weighs only 1.0 pounds
- No cooling features mentioned
The Casper Hybrid Pillow combines foam layers with a fiber core for balanced support all night, which is why Casper calls it ideal for side sleepers. Its outer foam layers maintain a consistent shape without needing fluffing, so it stays ready for use each morning. This makes it a straightforward choice for anyone who wants a reliable, maintenance-free pillow.
At just 1.0 pounds, this pillow is notably lightweight. The focus is on balanced support rather than plushness or cooling, as seen in other Casper models like the Hybrid Snow Pillow. It’s a simple pillow designed to do one job well.

How We Evaluated Casper Pillows
Our evaluation started with manufacturer specifications for materials, dimensions, and care instructions across the full Casper pillow lineup. We then studied expert round-ups and professional reviews to understand the performance differences between models, especially regarding support for side sleeper pillows. Finally, we analyzed patterns in verified owner feedback, looking for consistent comments on durability, temperature regulation, and comfort over time.
The key criteria were support and loft for spinal alignment, cooling features for temperature management, and overall feel and maintenance. This research-based approach provides a detailed comparison, but personal comfort preference remains the final deciding factor.
What To Look For In Casper Pillows
Casper offers several distinct pillow constructions, each with different benefits for side sleepers. The right choice depends on your need for support, temperature regulation, and whether you stay in one position all night.
Side sleepers generally need a firmer, higher-loft pillow (around 5 inches) to keep the head and neck aligned. Consider material feel, cooling technology, and ease of care when choosing among Casper’s models.
Support & Loft
Side sleepers need consistent support to bridge the gap between the neck and mattress. A pillow that is too soft or low allows the head to tilt down, straining the neck and shoulders. The ideal pillow height for side sleeping is typically between 5 and 6 inches, which helps maintain a neutral spinal alignment. Casper’s firm memory foam options, like the Essential, provide this consistent, non-collapsing support, while their Hybrid models offer a balanced foam-and-fiber feel.
Temperature Regulation
Many side sleepers find that pressure points, especially around the face and shoulders, can create heat buildup. A pillow that sleeps cool enhances comfort throughout the night. Look for integrated cooling technologies, like the gel infusion in the Essential or the proprietary Snow Technology in the Hybrid Snow model. Breathable covers, like the percale cotton on the Original, also promote airflow. For those who consistently sleep hot, prioritizing active cooling pillows is a key consideration.
Feel & Maintenance
The feel of a pillow, whether it’s firm memory foam, a balanced hybrid, or an adaptive down-alternative, is highly personal and affects how quickly you settle into sleep. Some prefer the dense, contouring feel of foam, while others like the plush, moldable quality of microfiber. Maintenance is also practical; most Casper pillows feature a removable, machine-washable cover, but the inner core’s care instructions vary. Consider how much nightly fluffing you’re willing to do versus preferring a pillow that holds its shape.
- Check the pillow’s loft measurement against your shoulder width.
- Read owner feedback on whether the pillow’s firmness softens over time.
- Verify if the entire pillow is washable or just the cover.
- Note the pillow’s weight, as heavier models can be harder to reposition. Consider if you need a pillow that works for side sleeping exclusively or for multiple positions.
Choose a pillow firm enough to prevent your ear from touching the mattress when lying on your side.

Frequently Asked Questions
Which Casper pillow was sold at Costco?
Casper has occasionally sold exclusive versions or bundles of its Original Pillow at Costco warehouses and online. These are typically value packs that may include two pillows, but the core design and materials match the standard retail Casper Original Pillow available elsewhere.
What are the differences between the Casper Essential and the Casper Original pillows?
The Casper Essential is a firmer, solid block of cooling gel-infused memory foam designed for consistent support, ideal for dedicated side sleepers. The Casper Original uses a softer, pillow-in-pillow design with down-alternative microfiber fill that adapts to movement, making it better for combination sleepers who change positions.
Is the Casper pillow worth it?
Casper pillows can be worth the investment for side sleepers seeking specific support and cooling features not always found in basic pillows. Their use of quality materials, thoughtful design for alignment, and inclusion of machine-washable covers offer good value in the mid-range bedding market, especially when paired with a compatible Casper mattress.
What is better, Casper or Purple?
Casper and Purple pillows serve different needs. Casper focuses on foam and hybrid designs with an emphasis on alignment and cooling for side and back sleepers. Purple’s Grid technology offers a unique, highly responsive feel that some find pressure-relieving. The “better” choice depends entirely on your preferred feel and sleep position; trying both brands’ sleep trials is the best way to decide.
Can you adjust the loft of a Casper pillow?
Most Casper pillows, like the Essential and Hybrid models, are not adjustable, their loft and firmness are fixed. The Casper Original’s two-chamber design offers some adaptability through compression, but for truly customizable loft, you would need to look at dedicated adjustable pillows where you can add or remove fill.
The Bottom Line
For side sleepers who want firm, consistent support and tend to sleep warm, the Casper Essential Cooling Foam Pillow is our best overall choice. If you prioritize all-night temperature control above all else, go directly to our best for hot sleepers pick, the Casper Hybrid Snow Pillow. For combination sleepers or those wanting a plusher, adaptive feel, the Casper Original Pillow is the most versatile option. Ultimately, ensuring the pillow provides enough loft to keep your spine aligned is the single most important factor for side-sleeper comfort.
