Leesa Sleep is an Arizona-based mattress and bedding retailer with a focus on community giving. For every 10 mattresses the company sells, it donates one bed to a charitable organization.

The Leesa Oasis Chill Hybrid Mattress is one of the brand’s best options for hot sleepers who prefer a surface that hugs their body closely. While the mattress lets sleepers sink into the surface, its cooling features combat heat retention, and a zoned core provides targeted spinal support.

This hybrid model comes in Plush and Cushion-Firm, which correspond to medium soft (4) and medium (5) on our 10-point firmness scale. While both are best suited to side sleepers, certain factors may influence which is ideal for you.

Below, we’ll break down what makes the Leesa Oasis Chill Hybrid Mattress unique, including its materials and construction, how it performed during our tests, and relevant pricing and policy information.

TEST LAB RATINGS

How the Leesa Oasis Chill Hybrid Scored

▲ Great 8.0–10 ● Good 6.0–7.9 ▼ Fair 5.9 or below

Motion Isolation▲8.0/10

Thanks to the Oasis Chill Hybrid’s thicker-than-average comfort system, it absorbs more vibrations than many comparable hybrid mattresses. The three foam layers and pocketed coils significantly limit the spread of motion.

In our evaluations, team members could barely feel when their testing partner changed positions on the other side of the bed. Sleepers who are sensitive to their partners’ movements may find the Oasis Chill Hybrid a great solution.

Colin Simpson, Product Research Manager: Hybrids don’t always isolate motion well, but this bed impressed us during kettlebell drop and motion measurement tests. The foam does an excellent job at absorbing movement.

Pressure Relief▲8.5/10

Like many hybrid models with generous comfort systems, the Oasis Chill Hybrid provides significant pressure relief. Its three foam layers cushion the surface and mold to a sleeper’s body to redistribute their weight. This combination creates a plush feel while preventing pressure buildup around key areas like the hips and shoulders.

Jeremy Klein, Product Testing Manager: The foam in this model is incredibly adaptive, so it molds to your body’s shape. It’s also really good at dispersing weight evenly — you really don’t feel much impact under your hips on this bed.

Temperature Control●7.0/10

As its name suggests, the Oasis Chill Hybrid is billed as a cooling mattress, and our temperature readings showed that the surface stays cooler than many models with close-conforming comfort systems.

The construction includes multiple pieces of cooling technology including a moisture-wicking cover as well as gel and copper infusions. Memory foam tends to sleep warm, but these additional components help counteract heat retention to keep you cool. The coil core also keeps air flowing freely.

Logan Foley, Executive Product Director: There’s quite a bit of body-hugging foam in this model, which is usually a recipe for heat retention. However, the cooling tech works as advertised, and this bed is cooler than you’d expect.

Edge Support▲8.0/10

Due to the Leesa Oasis Chill Hybrid Mattress’ thick comfort system, our testing team noted mild to moderate compression along the mattress perimeter.

The Cushion-Firm’s medium (5) feel contributed to a slightly more supportive perimeter. Most team members were comfortable sitting or lying along the edges, though those over 230 pounds felt much more secure in the center of the bed.

The Plush version’s medium soft (4) feel limited the space our testers were comfortable using. The instability made them feel like they could slip off if they got too close to the edge.

Brad Nehring, Product Testing Manager: If edge support is important to you, it makes sense to get the Cushion-Firm model instead of the Plush. It’s stronger at the edges and better at springing back to its original shape.

Ease of Movement●6.5/10

The Leesa Oasis Chill Hybrid Mattress is slightly more challenging to move on than the average hybrid model. Hybrid mattresses are often quite responsive due to their bouncy coil cores. But because of this model’s thick foam comfort system, our testing team barely detected the bounce of the coils.

Due to the plusher feel, testers also sank relatively deeply into the foam layers, impeding their movement. This was more pronounced on the Plush option than the Cushion-Firm. Additionally, the memory foam retained body impressions for a moment when testers moved, making position changes more difficult.

Mary Fenton, Head of Product Content: The Plush was pretty hard for me to move around on without feeling trapped. I had more luck with the Cushion-Firm, but I found both beds compressive rather than bouncy.

Durability●7.5/10

Pocketed coils make for a fairly durable support system, so the first part of a hybrid mattress to break down is usually the comfort system. The Leesa Oasis Chill comes in two firmness options, but neither design is particularly firm. You can expect a lifespan of six to seven years from either model.

HANDS-ON TESTING

Testing Team Takeaways

To test the Leesa Oasis Chill Hybrid Mattress, we had three people on our testing team take the bed home and test it for one week. Here are their initial observations.

“The Oasis Chill Hybrid was a major win for me. I honestly couldn’t decide between the two firmness options because I got great support on both. If you’re prone to hip soreness, this bed is worth thinking about.”

“This bed was kind of a mixed bag for me. I got solid support on my back and side, but the surface is pretty huggy, and I had a tough time switching between sleeping positions without getting stuck.”

“I think the Oasis Chill lives up to its name. It’s not the coolest hybrid we’ve ever tested, but it does a really great job at keeping air moving considering how conforming the foam is.”

Side Sleepers

The Leesa Oasis Chill Hybrid Mattress is best suited to side sleepers. Its three foam comfort layers let a side sleeper’s hips and shoulders sink in deeply, preventing pressure points from forming. Meanwhile, the zoned core adds extra support around the center of the bed to keep your spine aligned. 

Thanks to its medium (5) feel, our testers of all weights felt comfortable sleeping on their sides on the Cushion-Firm option. Those over 230 pounds noted that their hips and shoulders could use a bit more support, but they didn’t feel like their spinal alignment was significantly affected. The Plush option’s medium soft (4) feel relieved pressure build up exceptionally well for side sleepers under 130 pounds. Our testers above 130 pounds preferred the Cushion-Firm’s extra support.

Back Sleepers

The Leesa Oasis Chill Hybrid Mattress’ combination of contouring and zoned support works well for some back sleepers.The memory foam molds to your lumbar region to ease back pain and enhance comfort, while the support core’s zoning reduces hip sagging.

Our testers found the Cushion-Firm to be the better option for back sleeping. Most testers under 230 pounds felt comfortable lying on their back on this model, but those under 130 pounds were more enthusiastic about the surface’s balance of contouring and support.

Stomach Sleepers

According to our team, stomach sleepers under 130 pounds may enjoy the Oasis Chill Hybrid. Its thick comfort system cushions the front of a stomach sleeper’s body. The zoned core also provides enhanced support around a stomach sleeper’s midsection, reducing the risk of back strain.

That said, both of the Oasis Chill Hybrid’s firmness options were too soft for most of our testers. Those under 130 pounds could lie relatively comfortably on their stomach on either model, but they sank in more deeply than they would have liked. Testers over 130 pounds didn’t get the support they were looking for from either of the Oasis Chill Hybrid’s options, with those over 230 pounds finding the Plush version particularly uncomfortable.
