Leesa Reserve Hybrid Mattress Review

The Leesa Reserve’s thick foam layers set it apart from other hybrid mattresses in terms of motion isolation. I barely noticed any motion transfer from my sleep partner, and vice versa. – Brad

The Leesa Reserve Hybrid outperforms many competing hybrid models on motion isolation. Thanks to the thick layers of memory foam and individually wrapped coils, our testers found the mattress absorbed movements before they could travel across the bed.

The firm model doesn’t conform as closely, so it may transfer slightly more motion. That said, our testers reported that all three models kept disruptions to a minimum when sharing the bed with a partner.

The medium (5) Leesa Reserve really excels at pressure relief — the foam layers provided deep cushioning for my sore spots, but the zoned coils kept my spine aligned and prevented excessive sinkage around my midsection. – Jeremy

The medium (5) Leesa Reserve really excels at pressure relief — the foam layers provided deep cushioning for my sore spots, but the zoned coils kept my spine aligned and prevented excessive sinkage around my midsection.

Memory foam is known for its ability to evenly distribute weight by wrapping closely around the body. Our testers experienced standout pressure relief from the soft and medium Leesa Reserve Hybrid Mattresses, and this was confirmed by our pressure-mapping tests.

The firm model also performed fairly well in our tests, even though it didn’t conform as closely. This model was preferred by our testers weighing over 230 pounds, who found that the added support and the transitional layer helped cushion the transition to the support coils.

Normally I’m wary of thick layers of memory foam because they tend to get hot, but the Leesa Reserve Hybrid wasn’t so bad. The bed got a bit hot when I slept on it, but it didn’t cause my any serious issues. The coils put in some serious work to keep the bed cooler. – Danny

Using a heating element and a heat gun to take the temperature of the mattress, we found it retained some heat. This is normal for memory foam, particularly high-density foams like those used in the Leesa Reserve Hybrid.

Testers over 230 pounds experienced more heat buildup, especially on the soft model, as the mattress hugged them more closely.

Hybrid mattresses generally outperform foam beds on temperature neutrality, as air can circulate through the coils. While hot sleepers may prefer a mattress with a thinner comfort system, the Leesa Reserve Hybrid is an option if you sleep warm but enjoy the feel of memory foam.

Even though the surface is topped with memory foam, the edges of the Reserve Hybrid were surprisingly strong. The coil core provides a very solid base, and the memory foam layers are pretty dense, making them more resistant to sagging on the edges. – Danny

In our edge support tests, the perimeter of the Leesa Reserve Hybrid held up well under pressure. The mattress has stronger coils along the edges, which help prevent the sides from buckling.

The firm model performed best, with the soft and medium models allowing our testers to sink in a little when sitting on the edge of the bed. When it came to sleeping in the bed, most of our testers felt comfortable using the entire surface.

I noticed a bit of resistance when scooting across the Leesa Reserve. I wouldn’t say the mattress is hard to move on per se, but many of the other hybrids we’ve tested offer more responsiveness and don’t sink as much. – Brad

Our testers had some difficulty changing positions on the Leesa Reserve Hybrid, particularly the soft model.

Hybrid mattresses usually offer good ease of movement, since the coils provide a responsive springboard. However, memory foam conforms closely and has a slow response to pressure, which can lead to feelings of being stuck in the bed.

While still better than the average foam mattress, the Leesa Reserve Hybrid may not be the ideal mattress for combination sleepers.

The foam layers are compressed separately from the coils and had a stronger smell than I’m used to upon unboxing. That being said, the smell faded pretty fast once we laid the foam out. – Jeremy

Our team detected some off-gassing odors after unboxing the Leesa Reserve Hybrid Mattress. Off-gassing occurs when volatile organic compounds (VOCs) are released into the air, and it’s a common occurrence with any mattress containing synthetic foams.

Off-gassing is not considered dangerous, and the Leesa Reserve Hybrid is made with foams certified low in VOCs by GREENGUARD Gold and CertiPUR-US. Additionally, as this mattress contains coils, the odors should dissipate faster than with a solid foam mattress. If you’re sensitive to smell, you may prefer to let the mattress air out in a well-ventilated area before sleeping on it.
