The Casper Original Hybrid Mattress Review

The Casper Original Hybrid Mattress is available in three firmness levels: Plush, Medium, and Firm. This review evaluates the Casper Original Hybrid Medium mattress firmness. Ranking 6.5 out of 10 on our firmness scale, this Casper hybrid mattress offers a spot-on amount of bounce and responsiveness — a true medium firm feel that suits a wide range of sleeping positions and medium firm mattresses expectations.

The medium firmness of the Original Hybrid mattress is the most versatile option — delivering the balanced feel that combination sleepers, side sleepers, and back sleepers all benefit from. Casper offers a Plush version for those seeking softer comfort layers, and a firmer mattress Firm version for stomach sleepers and heavier sleepers who need more resistance and lumbar support. The Casper Original Hybrid Mattress Plush is particularly popular among lighter sleepers and side sleepers who prefer deeper body contouring.

The Casper Canada Original Hybrid Mattress is equipped with AirScape Technology and Phase Change Material to prevent overheating. The AirScape Technology is truly one of the most innovative features across Casper hybrid mattresses — working with Phase Change Material to facilitate airflow across the mattress and wick away heat and moisture for a comfortable temperature sleeping environment. For hot sleepers, this AirScape Technology combination is a breakthrough that can significantly increase sleep quality compared to standard all foam mattress or basic foam mattress alternatives.

The Original Hybrid also features a QuickCool™ Cooling Mattress Cover with cool-to-the-touch fibres for immediate surface-level temperature regulation. The combination of the flex coils base (which allows air to circulate through the mattress core) and the AirScape Technology comfort layers gives the Casper Original Hybrid cooling performance that far exceeds what an all foam mattress can achieve. For hot sleepers who need even more advanced cooling, Casper Canada offers the Casper Wave Hybrid Snow Mattress — their most cooling mattress with Snow Technology™ and HeatDelete® Bands.

Many sleepers find the Casper Original Hybrid Mattress to be exceptionally comfortable. From the moment you lie down on the Casper Original Hybrid, you'll fall in love with the cushiony comfort it offers. The breathable mattress cover combined with premium memory foam and flex coils delivers top-tier comfort layers and support for your body. The ergonomic zoned support minimizes pressure points and alleviates pain to provide the most restorative experience.

The Casper Original Hybrid mattress achieves a genuinely medium firm feel that balances contouring and responsive support — a combination that the best hybrid mattresses deliver but many all foam competitors struggle to replicate. Add in proper spinal alignment, and the Casper Original Hybrid creates a perfectly balanced sleeping experience. The Original Hybrid is designed in Canada and made with a blend of materials from Canada and other international partners — a Casper signature foam formulation that reflects the brand's commitment to sleep quality and durability.

The Casper Original Hybrid Mattress is a fantastic choice for couples or those looking to minimize motion transfer. In all our Casper bed reviews, we test rigorously for motion transfer — and the Casper Original Hybrid excelled consistently. The individually pocketed springs of the flex coils system contain movement at the individual coil level, delivering reduced motion transfer across the mattress surface. Our in-house tests confirmed that the Casper Original Hybrid achieves outstanding motion isolation — meaning you will have minimum interruptions to your sleep when a partner, pet, or child moves. For combination sleepers who shift positions throughout the night, this reduced motion transfer performance is particularly meaningful.

The Casper Original Hybrid does not sink excessively. The Original Hybrid's medium firm structure has made this one of the most stable Casper mattresses you will encounter. With minimal sinkage and more bounce from the flex coils to provide cushioned comfort, this Casper hybrid mattress feels just right. As the flex coils increase responsiveness to your body, the mattress recovers and responds quickly — adding to its already impressive comfort layers performance.

Unlike an all foam mattress where slow foam recovery can create a "stuck" sensation, the Casper Original Hybrid's flex coils deliver immediate rebound — making it easy to change sleeping positions without effort throughout the night. This more bounce responsiveness is one of the key reasons the Original Hybrid mattress suits combination sleepers so well.

The Casper Original Hybrid offers high-quality edge support through its Casper Edge Support reinforced perimeter. The ProSupport foam support layer creates a firm border around the mattress that ensures better edge support — helping individuals bed easily get in and out with no discomfort. There was no sinking, slipping, or falling off during our edge support testing, indicating the Casper Original Hybrid mattress is thoughtfully constructed for stability across the entire mattress surface, including the edges.

The Casper edge support system is a meaningful advantage over all foam competitors that often develop perimeter compression over time. Pairing the Casper Original Hybrid with a Repose Wooden Bed Frame or compatible slatted foundation further enhances the edge support performance, as the ProSupport foam base works best with even, solid foundation support. For heavier sleepers who place significant load near the perimeter, the Casper edge support holds firm — a reliable indicator of the Original Hybrid mattress's long-term durability.

Off-gassing describes the temporary chemical smell that comes with unboxing a new foam mattress, and the Casper Original Hybrid scores a solid 7.5 out of 10 here. That's a stronger showing than you'd typically expect from a mattress with this much foam and coil content packed into the box — Best Sleep Society's own testing notes that unlike many competing hybrid mattresses, the Casper Original Hybrid has minimal off-gassing upon unboxing, which is a welcome first impression for anyone setting up the mattress in a smaller or less-ventilated room. Because the mattress still relies on multiple layers of memory foam alongside its flex coil support system, some mild odour is normal and expected during the first few hours after unboxing, but it isn't the kind of lingering smell that requires days of airing out. For most sleepers, this means the mattress will be ready for regular use quickly, with sensitive sleepers still benefiting from letting the room ventilate for a bit before their first night.

Bounce is where the Casper Original Hybrid truly separates itself from Casper's all-foam lineup, earning an outstanding 9.8 out of 10. The difference comes down to construction: instead of relying on foam alone to cushion and recover, the Original Hybrid adds a full layer of individually pocketed flex coils beneath its zoned memory foam comfort layers. Coils respond independently to body weight and movement, and unlike an all-foam mattress where slow foam recovery can create a "stuck" sensation, the flex coils deliver immediate rebound, making it easy to change sleeping positions without effort. That rebound is amplified by the fact that the pocketed coils respond independently to body weight and movement, providing more bounce and responsiveness than any foam mattress can deliver on its own. In practice, this makes the Original Hybrid an excellent match for combination sleepers and couples — shifting positions or getting in and out of bed takes minimal effort, and the springiness doesn't come at the cost of the zoned pressure relief the memory foam layers still provide up top. If you've found all-foam mattresses too slow to move on, this is the kind of bounce that solves that problem directly.
