Yaasa ONE Mattress Overview
Yaasa Studios is an adjustable furniture company based out of Santa Barbara, California. In addition to the Yaasa ONE Mattress, they sell the Yaasa Mattress, adjustable beds, weighted blankets, pillows, sheets, and other bed-related products. Though they recommend purchasing the Yaasa ONE Mattress with the Yaasa ONE adjustable bed frame, customers may purchase the mattress on its own.
The Yaasa ONE Mattress is a hybrid mattress that measures medium-firm, or 6.5 out of 10 on the firmness scale. In this mattress, a layer of contouring memory foam sits above a layer of transitional polyfoam to provide sleepers with both cushion and support. The support core consists of a pocketed coil layer above a high-density foam layer.
This review describes how the Yaasa ONE Mattress performed in our tests, along with feedback shared by owners of the mattress. We’ve included everything you need to know to determine if this is the bed for you, including information about mattress construction, pricing, and details about Yaasa’s delivery options, sleep trial, and warranty policies.

Meet Our Testing Team
- Average-weight side sleepers. The bed’s hybrid construction provides side sleepers weighing between 130 and 230 pounds spinal alignment and pressure relief.
- Lightweight back sleepers. This mattress provides adequate lumbar support to lightweight back sleepers.
- People who are sensitive to smells. The off-gassing odor emitted from this bed is milder and dissipates more quickly than that from the average mattress.
- Shoppers on a budget. Compared to similar hybrid mattresses on the market, the Yaasa ONE sells at a lower price-point.
Not Recommended for...
- Heavyweight stomach sleepers. Most heavyweight stomach sleepers require a firmer mattress to feel supported.
- People who want a highly conforming mattress. Although there is a bit of “hug” to this mattress, it is also responsive. Sleepers who want to feel like they’re sleeping “in” the mattress should opt for something more conforming.
Tuck’s testing team conducted an extensive evaluation of the Yaasa ONE Mattress. Our review and rating process consists of three parts: in-house evaluation, external sleep testing, and data collection of verified owner experiences. To learn more about our review process, read our methodology here.

Sleep Position Ratings
As part of our ratings process, we evaluated the Yaasa ONE Mattress across different body types and preferred sleep positions. In addition to physical testing, we surveyed our sleep expert team and analyzed reviews from verified mattress owners and customers. Our findings are listed in the table below.
|Sleep Position||Less than 130 LBS||130 LBS - 230 LBS||Greater than 230 LBS|
How Is the Yaasa Mattress Constructed?
The Yaasa ONE has a cover made of Tencel lyocell. Tencel lyocell is a sustainable fabric made from pulp found in wood, bamboo, or eucalyptus. It is generally softer than cotton, breathes well, and is biodegradable at the end of its lifespan.
A ¾-inch layer of Cooling Infinity memory foam adds a contouring feel to this responsive bed. This layer has a gel infusion meant to draw heat away from sleepers.
Two inches of high-density polyfoam both cushion and support sleepers.
A transitional layer helps promote spinal alignment by allowing the heavier hips and shoulders to sink in more deeply, while keeping the abdomen lifted and supported. This polyfoam layer cradles the body, promotes spinal alignment, and keeps sleepers from sinking all the way down to the support core.
The support core comprises 6 inches of pocketed coils and a ¾-inch layer of high-density polyfoam. In addition to adding firmness to the bed, the coil layer helps keep the mattress cool. Airflow through this layer helps prevent a sleeper’s body heat from becoming trapped.
Pocketed coils, as opposed to innerspring coils, reduce motion transfer across the surface of the mattress. Pocketed coils allow each individual coil to be depressed separately from the rest.
At 10 inches, the profile of this mattress is average. Customers can expect standard sheets to fit the Yaasa ONE Mattress. The thickness of this bed provides space for a ¾-inch contouring comfort layer, a 2-inch transitional foam layer, a 6-inch pocketed coil support layer, and a ¾-inch high-density support foam layer.

What Are the Firmness and Feel Like?
The Yaasa ONE Mattress comes in one firmness option, which the company describes as medium, or 5-6 out of 10 on the firmness scale. Our testing found this rating to be slightly off. We view the Yaasa ONE Mattress as rating medium-firm, or 6.5 out of 10 on the firmness scale.
Medium-firm mattresses appeal to a broad range of sleepers. Most average-weight sleepers weighing between 130 and 230 pounds can find comfort on a medium-firm mattress.
Many lightweight and heavyweight sleepers can also enjoy a medium-firm mattress. The less a person weighs, however, the firmer a medium-firm mattress will feel to them. Similarly, the more a person weighs, the softer a medium-firm mattress will feel to them.
In terms of feel, the Yaasa ONE falls between being responsive and conforming. It provides a good option for sleepers who want to experience a little of the “hug” associated with memory foam, but don’t want to feel like they’re sinking into the bed.
In the next section, we’ll take a closer look at how the Yaasa ONE Mattress performed in our sleep category ratings. To rate a mattress, we analyze a wide range of data from our testing process, our sleep-testing team, and verified Yaasa owners.
Customers can expect the Yaasa ONE to be of average durability, which is 6-7 years. We came to this conclusion based on the mattress’s construction and materials. Pocketed coils are exceptionally durable and tend to last for many years, though they can develop creaks as they age.
Memory foam and polyfoam are less durable than coils. They can develop body impressions over time and eventually degrade. Regularly rotating the mattress head to foot every 3-6 months can help extend the life of the foam layers by changing which parts of the bed get the most use.
To assess motion isolation, we asked two sleep testers to lie on the Yaasa ONE at the same time. One tester moved around while the other paid attention to any movement they felt transfer across the surface of the mattress.
We determined that the Yaasa ONE is good at isolating motion. Generally, memory foam comfort layers absorb rather than transfer motion. Coil layers tend to transfer motion, though pocketed coils, like those in the Yaasa ONE, are better than innerspring coils at isolating motion.
When our testers unboxed the Yaasa ONE, they did notice a slight off-gassing odor. Off-gassing occurs when volatile organic compounds (VOCs) are released from newly manufactured products. Off-gassing is especially common with polyfoam and memory foam.
Off-gassing from the Yaasa ONE was mild and dissipated quickly, within hours. The mattress didn’t off-gas nearly as much as many all-foam beds do because the coil layer allows more airflow through the bed, which clears out off-gassing odors more quickly.
To measure pressure relief, we spread a pressure-monitoring pad across the top of the mattress and had testers of varying weights lie on top of it and change positions. This pad records and transmits a pressure map to a computer, for us to view.
We found that the Yaasa ONE did a good job of relieving pressure. Generally, sleep testers of all sizes did not experience intense pressure points while on the bed. Both the conforming memory foam and transitional polyfoam layers contribute to pressure relief in this bed.
Our testers found that the Yaasa ONE is good at remaining temperature neutral. With a 6-inch coil layer, air can easily flow through the bed and disperse body heat. Also, the memory foam comfort layer contains a gel infusion, which is meant to help reduce heat absorption.
Still, the foam comfort and transitional layers make the Yaasa ONE less temperature neutral than some other beds. Foam tends to trap heat more than other mattress materials, and some people who sleep hot could feel warm on this bed.
We asked our testers to sit on the edge of the Yaasa ONE to check for sinkage. The more edges sink, the more difficult it is for some people to get in and out of a bed. We also asked testers to lie near the edge of the bed and notice if they felt at risk of rolling off.
Overall, the Yaasa ONE has good edge support. The 6-inch pocketed coil layer brings firmness to the mattress’s edges. Still, the edges did sink a minor amount due to the foam comfort and transitional layers. This sinkage could limit the surface area of the mattress sleepers can comfortably use.
Our internal and external sleep testers agreed that the Yaasa ONE is pretty quiet. Most sleepers won’t be bothered by sounds in response to a partner’s movements or from their own movements on the bed.
Memory foam is known for absorbing sound and being virtually silent. Hybrid beds tend to produce some sound, however, due to the coil layer. Although the Yaasa ONE makes some light sound, the pocketed coils do not loudly creak or squeak like some innerspring mattresses are prone to do.
The Yaasa ONE earns a very good rating for sex, largely because of its responsive nature. Responsive mattresses are springier and tend to facilitate rather than inhibit movement. Although the Yaasa ONE contains memory foam, the layer is thin and not conforming enough to inhibit movement.
The Yaasa ONE also performs well in terms of edge support and noise, and both of these factors help when it comes to sex. Couples do not have to worry about the mattress creating loud noises. Good edge support allows for more of the bed’s surface to be safely used.
Now, let’s discuss our sleeper ratings for the Yaasa ONE Mattress.
There is no such thing as a universally ideal firmness and thickness for a mattress. Since sleepers have different body weights and preferred sleep positions, they also prefer different beds. To eliminate bias from our review, we evaluated the Yaasa ONE Mattress with sleep testers of different body weights and position preferences.
Lightweight Sleepers – Less than 130 lbs.
Lightweight sleepers of all position preferences rated the Yaasa ONE Mattress positively. Lightweight back sleepers rated the mattress higher than those with other position preferences, however. The Yaasa ONE provides adequate lumbar support to back sleepers in this weight group, while also relieving pressure.
Some lightweight sleepers, especially those at the lighter end of the scale, will prefer a softer mattress. Measuring 6.5 out of 10 on the firmness scale, the Yaasa ONE could feel too firm to some sleepers in this weight group.
Average Weight Sleepers – 130 to 230 lbs.
Average-weight sleepers of all position preferences also rated the Yaasa ONE Mattress positively. In this weight group, side sleepers gave the mattress the highest ratings. The Yaasa ONE promotes spinal alignment in side sleepers, keeping them both supported and cushioned.
Medium-firm, or 6.5 out of 10 on the firmness scale, is a firmness level that generally appeals to average-weight sleepers. Average-weight sleepers who prefer a firmer rather than softer bed that’s more responsive with only a bit of “hug” will enjoy the Yaasa ONE.
Heavyweight Sleepers – More than 230 lbs.
Among heavyweight sleepers, those who prefer to sleep on their backs or sides rated the mattress positively. The 6.5 firmness level and transitional polyfoam layer provide adequate lumbar support to back sleepers and spinal alignment to side sleepers.
Stomach sleepers in the heavyweight group didn’t prefer the mattress, however. Generally, stomach sleepers require a firmer mattress that supports the midsection. Otherwise, softer mattresses can put strain on the lower back, hips, shoulders, and neck. As a result, most heavyweight stomach sleepers would probably fare better with a firmer mattress.

How Does the Yaasa Mattress Compare to Other Beds?
With so many similar mattresses on the market, it can be difficult to figure out which model works best for you. In this section, we compare competing mattresses with the Yaasa ONE to help you better determine which bed fits your unique needs.
Yaasa ONE Mattress vs. Yaasa Mattress
The Yaasa ONE shares similarities with the original Yaasa Mattress, but there are also differences. Although the Yaasa was the company’s flagship mattress, it is now considered their luxury model. The Yaasa costs a few hundred dollars more than the Yaasa ONE at each size.
Available in two firmness levels, the Yaasa offers customers more options. The medium-firm Yaasa rates 6.5 out of 10 on the firmness scale, which is also how we rate the Yaasa ONE. The Yaasa also comes in medium-soft, providing another option for lightweight sleepers who might find the Yaasa ONE too firm.
Regardless of firmness level, the Yaasa has a more conforming feel than the Yaasa ONE. Both are hybrid mattresses, but with more memory foam, the Yaasa has more “hug.” It’s also a thicker mattress, measuring 12 inches in height compared to the Yaasa ONE’s 10 inches.
Yaasa ONE Mattress vs. WinkBed
Like the Yaasa ONE, the WinkBed is a hybrid mattress containing polyfoam and coil layers and a Tencel lyocell cover. The WinkBed is constructed differently, however. In addition to pocketed coils, the WinkBed has a microcoil layer and more foam layers than the Yaasa ONE. Overall, it measures 14.5 inches, which is 4.5 inches thicker than the Yaasa ONE.
The WinkBed tends to rate higher than the Yaasa ONE across the board, and that difference in quality is reflected in its price. WinkBed Mattresses cost about twice as much as the Yaasa ONE at every size.
The WinkBed comes in four firmness options, making it attractive to a wider range of people. WinkBed firmness options are “soft” (4.5), “luxury firm” (6.5), “firm” (7.5), and “plus” (8). The “luxury firm” option is most similar to the Yaasa One, which also rates 6.5 out of 10 in firmness.
Yaasa ONE Mattress vs. Tuft & Needle Hybrid
Like the Yaasa ONE, the Tuft & Needle Hybrid is a hybrid mattress. The two beds share a similar feel, which is a mix of responsiveness and contouring. Both give the body a little “hug,” but sleepers generally feel like they are lying “on” rather than “in” the mattress. The T&N Hybrid measures 5.5 out of 10 in terms of firmness, so it will appeal to sleepers who want a softer bed than the Yaasa ONE.
Price is one of the major differences between these two beds. The Tuft & Needle Hybrid costs several hundred dollars more than the Yaasa ONE, depending on the size. This price difference is largely due to quality of materials.
Customers can expect the Tuft & Needle Hybrid to sleep cooler and last longer than the Yaasa ONE. The Tuft & Needle Hybrid contains breathable foam and a graphite infusion that is intended to help with cooling.
Yaasa ONE Mattress vs. Brooklyn Bedding Aurora
The Brooklyn Bedding Aurora Mattress is a hybrid available in three firmness levels: soft (3.5), medium (5.5), and firm (7.5). Since the Aurora’s firmness levels differ from the medium-firm (6.5) Yaasa ONE, they provide options for sleepers who want a softer or firmer bed.
In addition to firmness, the mattresses vary both in thickness and feel. The Brooklyn Bedding Aurora Mattress is an above-average profile mattress measuring 13.5 inches thick. At that size, it requires deep-pocket sheets. In comparison, the Yaasa ONE has an average, 10-inch profile.
Although both beds are hybrids, the Brooklyn Bedding Aurora is much more conforming and provides better pressure relief as a result. Sleepers who like to feel “hugged” by their mattress will prefer the Aurora.
Finally, price is a major differentiating factor between the two beds. The Brooklyn Bedding Aurora is made of higher quality materials, which is why it costs more than the Yaasa ONE, depending on the size.
Yaasa ONE Mattress vs. Bear Hybrid
Like the Yaasa ONE, the Bear Hybrid is a medium-firm hybrid mattress. The Bear Hybrid measures 6 out of 10 on the firmness scale, making it slightly softer than the Yaasa ONE. The Bear Hybrid is a good option for sleepers wanting a responsive bed. It is even less conforming than the Yaasa ONE.
Both beds rate highly with average weight side sleepers. One area in which the Bear Hybrid excels is at supporting lightweight stomach sleepers. The Yaasa ONE doesn’t perform quite as well with this group.
The Bear Hybrid rates higher on temperature neutrality, which could be a draw for sleepers who sleep hot. Its Celliant fabric cover is the secret to keeping sleepers cool all night long. Celliant technology absorbs body heat, then converts it into infrared energy. In addition to cooling, this process is said to aid with physical recovery, making the Bear Hybrid a good choice for athletes.
