The Yaasa Mattress is a hybrid bed containing both pocketed coils and foam layers. It’s available in two firmness levels: “soft,” which measures medium-soft, or 4 out of 10 on the firmness scale and “firm,” which measures medium-firm, or 6 out of 10.
In addition to the Yaasa Mattress, Yaasa sells another mattress option called the Yaasa ONE. Like the Yaasa Mattress “firm” option, the Yaasa ONE is a hybrid bed that rates 6 out of 10 on the firmness scale. The Yaasa ONE sells at lower price points, however, and has a 10-inch profile compared to the Yaasa Mattress’s 11-inch profile.
Beyond mattresses, the Yaasa company sells an adjustable bed frame, pillows, sheets, a mattress protector, blankets, an adjustable desk, and an office chair. Yaasa primarily sells products directly to consumers online. They also sell items in their showrooms, which are located in Santa Barbara, Chicago, and Minneapolis, as well as in some retail stores.
This review focuses exclusively on the Yaasa Mattress. In it, we reveal results of our mattress testing, analyze the materials and construction of the bed, and provide information to help you determine if the Yaasa Mattress fits your needs.
The Yaasa Mattress is a hybrid bed. It contains two comfort layers: a soft, uppermost layer made of memory foam and a transition polyfoam layer that sits beneath it. The bed also contains two support core layers: a 6-inch pocketed coil layer atop one inch of polyfoam. These four layers give the mattress an 11-inch profile, which fits standard sheets.
The memory foam, polyfoam, and pocketed coil combination give this bed a feel that is both conforming and responsive. Although the Yaasa Mattress doesn’t conform to the body as closely as some all-foam beds, its memory foam comfort layer does give a “hugging” sensation.
Sleepers considering the Yaasa Mattress may choose from two options: one medium-soft and one medium-firm. The medium-soft option rates 4 out of 10 on the firmness scale, while the medium-firm option rates 6 out of 10. Both contain the same layers, measure the same thickness, and cost the same amount.
The Yaasa Mattress’s memory foam layer is infused with titanium. This metal infusion is intended to have a cooling effect, counteracting memory foam’s tendency to trap heat. A phase change material cover also provides a cooling effect, transforming body heat into a lower temperature.
Both firmness options of the Yaasa Mattress are constructed with two foam comfort layers and a support core containing a layer of pocketed coils atop polyfoam. Phase change material covers the bed, providing sleepers with a temperature neutral sleeping surface.

Prices for the Yaasa Mattress align with what is average for high-quality hybrid mattresses. Generally, hybrid beds cost more than all-foam mattresses. This price difference stems from differences in the costs of materials. Coils tend to cost more than foam.
The Yaasa Mattress comes in two firmness options (“soft” and “firm”), and both options are priced identically to each other at each size.
Sleepers who are interested in a Yaasa Mattress but find these beds beyond their budget might want to consider the Yaasa ONE. The Yaasa ONE is another hybrid manufactured by Yaasa. It costs $400 less at each price-point. Unfortunately, the Yaasa ONE is somewhat less durable and pressure relieving than the high-quality Yaasa Mattress.

Both the “soft” and “firm” Yaasa Mattress options isolate motion well as a result of multiple construction elements.
The uppermost memory foam layer of the Yaasa Mattress is soft and conforming, so it absorbs motion. The pocketed coils are individually encased, so they do not spread motion the way innersprings do.
Motion isolation is most important to people who share a bed with a partner, children, or pets. When a mattress isolates motion well, sleepers are not likely to be disturbed by movements coming from others on the bed.
Due to the construction of the Yaasa Mattress’s comfort layers, the mattress relieves pressure well. The memory foam comfort layer is soft and conforming, contouring to the body’s curves. Below it, the transition polyfoam layer provides a mixture of softness and support, ensuring that heavier parts of the body don’t sink down to the support core.
When a mattress relieves pressure well, sleepers are less likely to experience pain or discomfort while lying on it. A pressure-relieving mattress evenly distributes a person’s body weight and promotes spinal alignment, so pressure points don’t form.
Soft: 3/5, Firm: 4/5
Like most hybrid beds, the Yaasa Mattress succeeds at keeping sleepers cool throughout the night. First, its phase change material cover absorbs body heat and transforms it to a cooler temperature. Then, titanium in the memory foam comfort layer helps counteract foam’s tendency to trap heat. Finally, the pocketed coil layer allows for more airflow than foam, which also distributes body heat and keeps the bed cool.
The two Yaasa Mattress firmness options do perform slightly differently when it comes to temperature control. The “soft” firmness option is somewhat less effective at staying cool than the “firm” option. That said, both models rate positively in terms of coolness.
Soft: 2/5, Firm: 3/5
The “firm” option of the Yaasa Mattress has stronger edges than the “soft” option. Most sleepers find the “firm” option has strong enough edges to allow for full use of the surface of the bed. These edges don’t put most sleepers at risk of rolling off the bed when sitting or lying near its edge.
The “soft” Yaasa Mattress doesn’t have firm enough edges for all sleepers, however. Some sleepers might find they do not want to sleep on or close to the edge of the “soft” Yaasa Mattress because doing so causes the edges to buckle or fold.
Most sleepers have no major problems when moving on the surface of the Yaasa Mattress. Although the mattress does “hug” the body a bit and provide a conforming feel, it is also fairly responsive. Sleepers don’t sink into the bed so deeply that they have trouble getting out of bed or rolling over, which can be an issue on ultra conforming mattresses.
Ease of movement is important for a few reasons. When a mattress inhibits movement, sleepers might not sleep as soundly because attempting to roll over could wake them up. Difficulty moving on top of a mattress can also be troublesome during sex.
The Yaasa Mattress rates positively for sex, largely because its surface is fairly easy to move across. People using the mattress don’t usually find difficulty in getting on and off the bed or changing positions.
The mattress would rate higher for sex if it had better edge support, however. Some people might find that they must avoid the edges of the “soft” Yaasa Mattress during sex, lest they fall off the bed because of buckling edges.
Compared to other mattresses, the Yaasa Mattress off-gasses an average amount. Customers can expect to smell an odor when they first unbox the mattress. As the bed expands and airs out, the odor will dissipate. Any smells should become undetectable within a day or so.
Off-gassing occurs when volatile organic compounds (VOCs) escape from newly manufactured products. Generally, hybrid mattresses like the Yaasa off-gas less than all-foam beds. This difference is due to the beds’ materials. Coils tend to off-gas less than foam, and they also allow for airflow that can help off-gassed odors dissipate more quickly.
Side Sleepers: Side sleepers of all body weights rate the Yaasa Mattress highly. This bed’s transition layer promotes spinal alignment in side sleepers by keeping heavier body parts from sinking down to the support core. With spinal alignment maintained, side sleepers experience pressure relief instead of pressure points.
Side sleepers weighing less than 130 pounds tend to prefer the “soft” Yaasa Mattress and rate it exceptionally well. Side sleepers weighing between 130 and 230 pounds like both the “soft” and “firm” mattresses, depending on personal preference. Sleepers weighing over 230 pounds require the additional support provided by the “firm” mattress option.
Back Sleepers: Back sleepers across the weight spectrum find that the Yaasa Mattress provides adequate lumbar support and pressure relief. Since the Yaasa Mattress feels both conforming and responsive, it gives back sleepers the “hug” of memory foam without allowing them to sink into the mattress too deeply, which can create discomfort.
Back sleepers weighing under 130 pounds can choose between the “soft” and “firm” mattress options. People who prefer more “hug” will enjoy the “soft” option, while those who like a firmer feel will prefer the “firm.” Back sleepers weighing over 130 pounds should opt for the “firm” option. The “soft” option isn’t firm enough to support most back sleepers in this weight range.
Stomach Sleepers: Like side and back sleepers, most stomach sleepers rate the Yaasa Mattress highly. Stomach sleepers require a firmer bed, and the “firm” option of the Yaasa Mattress is able to offer adequate support to stomach sleepers of all body weights.
When stomach sleepers lie on a mattress that’s too soft, their body can sink in too deeply, putting pressure on the neck and back. For this reason, only stomach sleepers weighing less than 130 pounds should opt for the “soft” Yaasa Mattress. Those over 130 pounds require the additional support the “firm” option offers.
