The Wave Hybrid Snow Mattress is available in three firmness levels. Whether you prefer a Plush mattress, Medium mattress, or Firm mattress, you don't have to sacrifice the coolest sleep of your life to keep your body comfortable and supported just the way you like it.

What's the difference?
We've designed three versions of our best-selling Wave Hybrid Snow Mattress, all with quality materials and the same innovative Snow Technology™, Zoned Support™ Ergonomic Foam, AirScape® Cooling Foam, and Gel Support Pods. The Wave Hybrid Snow Medium features the perfect balance of support and cushion, while the Plush version features softer foam layers to relieve pressure points for side sleepers, and the Firm version is made with firmer foam layers to ensure spinal alignment for stomach and back sleepers.

The Wave Hybrid Snow Mattress is perfect for hot sleepers. This innovative cooling mattress features Snow Technology™, including HeatDelete® Bands that pull heat away from your body while you sleep, as well as Cooling Phase Change Material and a QuickCool™ Cooling Mattress Cover that provide a cool-on-contact experience. There are also multiple mattress layers made with AirScape® Technology to promote better airflow.

Step 1: Protect your mattress
We strongly recommend using a mattress protector to prevent damage to your Casper mattress (plus a protector makes cleaning simple—just remove and wash as needed). Check out the Casper Mattress Protector or Casper QuickCool™ Mattress Protector, both of which are waterproof and designed to shield your mattress against stains, dirt, and wear.

Step 2: Keep it clean
No protector? Just spot clean gently with mild detergent and water, and let it air dry.

Step 3: Rotate to maintain
Rotate your mattress 180 degrees every three to six months to ensure it wears evenly. Do not flip it—Casper mattresses are designed with a specific top and bottom.

The Wave Hybrid Snow Mattress is Casper’s most premium mattress, designed for Canadians seeking advanced support and cooling in one sleep solution. It features targeted ergonomic Zoned Support™ with Gel Support Pods for softer support under the hips and firmer support under the lower back, as well as Casper’s advanced cooling Snow Technology™ to help reduce overheating throughout the night. This combination makes it especially well suited for people who experience back pain but also tend to sleep hot, which is a rare find in the Canadian mattress market.

The Wave Hybrid Snow Mattress was also named Product of the Year 2025 in the Mattress-in-a-Box category (based on a survey of 4,000 Canadians conducted by Kantar) and is one of the best-selling mattresses at Sleep Country Canada, where it’s frequently recognized for its premium cooling features and supportive design.

The Wave Hybrid Snow Plush is best for sleepers who want the softest, most pressure-relieving feel in Casper’s most advanced mattress, without giving up targeted support and cooling technology. Its plush comfort layers are designed to gently cushion the body, making it especially well suited for side sleepers, who benefit from extra give around the shoulders and hips.

As a Wave Hybrid Snow Mattress, it still includes advanced features like ergonomic Zoned Support™, Gel Support Pods, Flex Coil Supportive Pocketed Springs, and Snow Technology™, helping maintain spinal alignment and temperature regulation even with its softer feel. It’s a strong choice for sleepers who prioritize deep comfort and pressure relief but still want high-end support underneath.

The Wave Hybrid Snow Medium is best for sleepers who want a balanced blend of cushioning comfort and targeted support, paired with Casper’s most advanced cooling technology. Its medium feel works well for a wide range of sleep positions, making it a strong option for combination sleepers and couples who need a versatile, middle-ground firmness.

It features ergonomic Zoned Support™ and Gel Support Pods to help promote healthy spinal alignment, while Flex Coil Supportive Pocketed Springs add responsive support and airflow. Cooling Snow Technology™ helps regulate temperature throughout the night, making it a great choice for sleepers who want both comfort and consistent cooling performance in a premium hybrid design.

The Wave Hybrid Snow Firm is best for sleepers who prefer a more supportive, lifted feel with minimal sink, combined with advanced pressure relief and cooling technology. Its firmer design is especially well suited for back and stomach sleepers, who benefit from stronger support through the hips and lower back to help maintain healthy spinal alignment.

It features ergonomic Zoned Support™ and Gel Support Pods for targeted alignment, along with Flex Coil Supportive Pocketed Springs for responsive support and airflow. Cooling Snow Technology™ helps regulate temperature throughout the night, making it a strong choice for sleepers who want a firm, highly supportive mattress that still delivers premium comfort and cooling performance.
