10 Best Casper Pillows 2025 in the United States

The Casper Original Pillow in king size offers a comfortable medium firmness that suits many sleepers who want a balance between softness and support. Its unique pillow-in-pillow design with microfiber fill mimics the feel of down, providing a plush yet supportive surface. The 2-inch gusset helps with neck alignment, which can be beneficial for side and back sleepers seeking better posture during sleep.

The pillow’s 100% cotton percale cover is breathable and designed to keep you cool throughout the night, a great feature for those who tend to sleep hot. Additionally, the outer layer is removable and machine washable, making it easy to keep clean. The fill is resistant to clumping, so the pillow maintains its shape with just a quick fluff. However, the pillow is not adjustable in loft or firmness, so if you prefer customizing your pillow’s height or softness, this might be a limitation.

It uses hypoallergenic microfiber fill (a down alternative), though some users with very sensitive allergies might still want to verify compatibility. The pillow comes in a convenient two-pack, offering good value, and is backed by a 1-year warranty. This pillow is a solid choice for those who favor a medium loft and a plush feel, providing support, coolness, and easy care without requiring adjustments.

The Casper Sleep Essential Cooling Pillow offers a good balance of comfort and support with its chambered design. This design provides responsive support on the inside while maintaining a plush softness on the outside, which can be quite appealing for those looking for a medium-firm pillow. The pillow is made with a down alternative fill and has a 100% cotton outer shell, contributing to its breathability and comfort. Additionally, the ultra-breathable cover aims to enhance airflow, making it suitable for hot sleepers or those who experience night sweats.

However, the pillow has a fixed loft, meaning it may not be adjustable to individual preferences, which could be a downside for some users who prefer customizable options. Despite this, its cooling features allow it to stand out, especially for those who prioritize temperature regulation during sleep. The pillow is hypoallergenic, which is a benefit for allergy sufferers. It's also notable that the pillow is dry clean only, which might be less convenient for some users.

Weighing 4.3 pounds, it has a reasonable heft that contributes to its stable feel on the bed. The standard size fits well with most bedding, and its plain, white color ensures it blends seamlessly with any bedroom decor.

The Casper Sleep Essential Cooling Pillow in King size is designed to offer medium firmness with a comfortable balance of softness and support. It features a breathable polyester cover and a chambered design that helps keep airflow steady, making it a good choice if you tend to sleep hot or want a cooler pillow experience. The pillow’s loft is moderate, giving enough height for proper neck support without feeling too firm or too flat, appealing to side and back sleepers alike.

While it doesn’t have adjustable fill, the responsive chambered interior provides consistent support throughout the night. Made with polyester fill and a cotton outer shell, it’s lightweight and easy to care for, though dry cleaning is recommended, which might be less convenient for some users. The pillow is also hypoallergenic, which can benefit those sensitive to allergens.

If you prefer a very plush or very firm pillow, or want a fully adjustable option to customize loft and firmness, this pillow might not fully meet those needs. Its cooling features and medium firmness make it a solid pick for anyone looking for a supportive pillow that stays comfortable and fresh in warmer conditions.
