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 sleeper types. Because it lands right in the middle, very lightweight sleepers may find it slightly firm and heavier sleepers slightly soft — a normal trade-off for any medium firm mattress.

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 with softer foam layers, and a firmer mattress, the Firm, for back and stomach sleepers and heavyweight sleepers who need enough support in the lumbar region. The Plush is particularly popular among lighter sleepers and side sleepers who prefer deeper body contouring, while average weight sleepers tend to do best on the Medium.

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 combination can significantly improve sleep quality compared to foam mattresses with a traditional memory foam feel, which tend to retain heat.

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 this Casper hybrid cooling performance that far exceeds what an all foam bed can achieve, since the hybrid design allows better temperature regulation for hot sleepers. For hot sleepers who need even more advanced cooling, Casper Canada offers the Casper Wave Hybrid mattress in its Snow version, 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 cover, premium memory foam, and flex coils deliver excellent pressure relief, while the ergonomic zoned support minimizes pressure points for a restorative night.

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 spinal alignment that keeps the spine neutrally aligned, and the Casper Hybrid creates a perfectly balanced sleeping experience. Many sleepers with back aches notice real pain relief, though firmness preferences vary widely between individuals. This Casper 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 every Casper mattress review we publish, we test rigorously for motion isolation — and the Casper Original Hybrid excelled consistently. The individually pocketed springs contain movement at the coil level, so little motion travels 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. That's particularly meaningful for combination sleepers who shift positions throughout the night.

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.

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. That responsiveness is one of the key reasons it suits combination sleepers and senior sleepers who want an easier time moving and getting up.

The Casper Original Hybrid offers high-quality edge support through its reinforced perimeter. The ProSupport foam base creates a firm border that helps you get in and out of bed with no discomfort. There was no sinking, slipping, or rolling off during our testing, a sign the mattress is built for stability right to the edges. Strong edges also prevent excessive sagging and make sitting at the side of the bed comfortable.

This is a meaningful advantage over all foam competitors that often develop perimeter compression over time. Pairing the mattress with a Repose Wooden Bed Frame or compatible slatted foundation further enhances performance, as the ProSupport base works best with even support. For heavier sleepers and senior sleepers who sit near the perimeter, the border holds firm — a reliable indicator of 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.
