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.

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.

Answer a few questions to find the right mattress for your unique needs

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. That being said, some heavier stomach sleepers may find the bed too soft for their needs.
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.

Yaasa Mattress Review Breakdown
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.

Mattress Prices and Sizing
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.

Trial, Warranty, and Shipping Policies
Availability
The Yaasa Mattress is available for purchase online via the Yaasa website. It is not sold on Amazon.
Yaasa Mattresses are also available in-person at Yaasa showrooms located in Santa Barbara, Chicago, and Minneapolis. Yaasa also partners with some retail outlets to sell their mattresses, but they don’t list the names or locations of these partners online.
Shipping
Yaasa ships for free within the contiguous United States. Online orders will not ship to Hawai’i or Alaska, but customers may call to make arrangements for orders to ship to these locations. Yaasa does not ship internationally.
Once your order is placed, Yaasa will email you with shipping information. This email will include a tracking number and estimated delivery date.
Customers who take advantage of free shipping are responsible for setting up their bed and disposing of their old mattress. Those who pay extra for white glove delivery and old mattress removal, however, will have these tasks done for them.
Additional Services
Yaasa offers white glove delivery, which they call “in-home delivery and setup.” This service is only available in the contiguous United States. An adult must be home at the scheduled delivery time, and workers will set up the delivered items.
White glove delivery costs $199 for customers purchasing the Yaasa Mattress and adjustable bed frame. The service is also available to customers who don’t purchase the bed frame, but customers must inquire to learn the cost.
Old mattress removal is also available for an additional fee. Only customers paying for white glove delivery can opt to also purchase old mattress removal. Customers must inquire about the fee.
Sleep Trial
The Yaasa Mattress comes with a 100-night sleep trial. Customers must try out the mattress for a minimum of 30 nights before initiating a return. After 30 nights, the mattress may be returned within 100 nights of when it was delivered.
Customers must take the Yaasa Mattress out of its box in order to be able to return it. If the mattress remains in the box for over 20 days after delivery, the sleep trial and warranty may be void.
Once a return is initiated, Yaasa will make arrangements to have the mattress donated or recycled. Customers do not have to pay to have the mattress returned. Tags must still be on the mattress in order for it to be accepted as a return.
Warranty
The Yaasa Mattress comes with a 10-year limited warranty. Only the person who originally purchased the mattress may use the warranty. The warranty may also be void if the mattress is left in its box for 14 or more days after delivery.
The warranty covers damage to the foam or coils that happened during normal use, along with body impressions deeper than 1.5 inches. If the mattress was damaged by a person or not kept on a solid bed frame, the warranty may be void.
Customers should email [email protected] to make warranty claims. During the first five years of the warranty, Yaasa will completely replace the mattress with a new one. During years six through ten, they will provide a credit. The credit operates as follows:
Years 6 – 7: 60% of original purchase price
Years 8 – 9: 50% of original purchase price
Year 10: 30% of original purchase price
