Watch the video below to see how the Zoma Mattress performed when put to the test in the Sleep Foundation Lab.
The Zoma mattress is constructed with 3 layers of foam and a stretchy polyester-spandex cover. The cover is designed to wick moisture away from the sleeper, and it is perforated with tiny holes to allow body heat to pass through. Zoma recommends spot-cleaning the cover when needed.
In total the mattress measures 11 inches thick, which is marginally thicker than the average all-foam mattress. The primary comfort layer consists of 2 inches of Triangulex zoned memory foam. This foam is quite low-density, meaning it doesn’t conform as closely. However, it has a quicker response to pressure and sleeps cooler than denser memory foam.
The Triangulex foam is designed with triangle-shaped cutouts that gives it a firmer feel in the middle third of the bed. The aim is to provide targeted pressure relief in the shoulders and added support in the lumbar area. The foam is open-cell, and the grooves in the surface of the foam provide extra room for airflow.
The second layer is made with 2 inches of Reactiv foam, which is slightly firmer. This layer forms a firm cradle that helps the sleeper transition to the support core. It also absorbs motion to reduce nighttime disruptions from a sleeping partner.
Below this is the high-density polyfoam support core. This layer is 7 inches tall and the foam is extremely firm compared to the other layers, forming a durable base that helps keep the spine on an even plane.
Overall, the Zoma Sleep Mattress has a firmness level rated as medium. On a scale of 1 to 10 with 10 being the firmest, this would equate to about a 5. That said, due to the zoned comfort layer, the mattress feels firmer in the midsection and softer in the shoulders and legs. Sleepers under 130 pounds experience light contouring, while heavier sleepers sink in further for a feel that is halfway between sleeping “in” and sleeping “on” the bed.
All of the foams used in the Zoma mattress are certified low in harmful emissions by CertiPUR-US. The mattress is made in the U.S.

The Zoma mattress has a fairly low price-point for a mattress in its category. It’s a relatively new mattress, but based on our testing, we expect it to have a comparable lifespan to competing all-foam models. This makes it a good-value purchase for shoppers looking to invest in a quality mattress. Occasional discounts in the neighborhood of $100, or more during major holidays, may reduce the price even further.
The Zoma mattress is available in all the standard mattress sizes, as well as split king size.

Of all sleeper types, the Zoma is best-suited to side sleepers. The zoned comfort layer is ideally designed to relieve pressure points in the shoulders, which are a common issue when sleeping on the side. Meanwhile, the firmer foam in the midsection helps keep the hips in line with the rest of the body. On the whole, the mattress does a good job of conforming to the shape of the sleeper’s body and promoting healthy spinal alignment in most side sleepers.
In terms of body weight, side sleepers under 130 pounds benefit most from the mattress’s medium feel, while those between 130 and 230 pounds also receive enough support. By contrast, those who weigh more than 230 pounds may find the mattress too plush. Depending on where the individual carries more weight, this may cause uneven sagging that can negatively affect their spinal alignment.
Back sleepers who weigh less than 230 pounds should sleep comfortably on the Zoma mattress. Firmer foam in the middle third of the mattress helps fill in the lumbar area, and the polyfoam base supplies a stable surface to keep the spine aligned.
Due to its medium feel, the Zoma mattress may not succeed in maintaining spinal alignment in back sleepers over 230 pounds. These sleepers exert more pressure on the mattress and usually require the added support of an innerspring core. Despite the zoning in the Zoma mattress, these sleepers are likely to experience too much sagging in the hips. This can lead to lower back pain.
The Zoma mattress’s medium feel is well-suited to stomach sleepers under 130 pounds. For these individuals, the mattress is just firm enough to promote proper spinal alignment while reducing any pressure points that may crop up.
It’s a different story for those who weigh more than 130 pounds. Stomach sleepers generally need a firmer surface in the range of 7 to 8 on the firmness scale in order to avoid excessive sagging in the midsection. The Zoma mattress does have firmer foam in this section, but it’s not quite firm enough to support the hips and this may cause back and neck pain.

The Zoma mattress is available for purchase on the Zoma website or through third-party retailers including Amazon, Wal-Mart, and Target. Shipping is free in the contiguous U.S., with an extra charge for orders in Hawaii, Alaska, Canada, and Mexico.
Zoma mattresses are shipped for free to the contiguous U.S. via FedEx curbside shipping. Customers in Alaska, Hawaii, Canada, Mexico, or other international destinations should contact Zoma directly for shipping rates.
Mattresses are usually shipped within 3 to 5 days of order placement, and they take another 1 to 5 business days to arrive at your home. Customers don’t typically need to sign for mattress delivery but Zoma may require a signature for orders that include an adjustable bed.
As with many mattresses sold online, the Zoma is shrink-wrapped and compressed. To set it up, place it on the foundation, remove the box and plastic, and let it expand. Mattresses can usually be slept on after 4 to 6 hours, but the foam may take a day or two to reach its full size.
Zoma currently does not offer White Glove delivery or old mattress removal.
Zoma Sleep offers a 100-night sleep trial during which customers can return the mattress for a full refund if they are not satisfied. This sleep trial also extends to customers who purchased the mattress in a brick-and-mortar store.
Zoma asks that customers allow 30 nights for their body to adjust to the feel of the new mattress before reaching a decision. In the event of a return between the 30th and 100th night, the company arranges for free pick-up of the mattress. There is no need to keep the box. Where possible, the mattress will be either donated or recycled.
The Zoma mattress is backed by a 10-year non-prorated warranty against workmanship and structural defects. Mattresses that are deemed defective during this time will be repaired or replaced at Zoma’s discretion.
The warranty covers visible indentations of at least 0.75 inch, unless these result from use with an improper foundation or platform. Issues not covered by the warranty include normal increases in softness or decrease in the recovery characteristics, as these do not affect its pressure-relieving qualities.
The warranty shall be void in the event that the mattress is damaged, burned, physically abused, saturated with moisture, torn, cut, or in an unsanitary condition.
Zoma stipulates that the mattress must be used on a solid foundation or platform. If used with a box spring, sleepers should put a piece of 0.75-inch thick moisture-resistant plywood over top. Slatted bases should have slats no further than 3 inches apart. Customers will be asked to provide proof that they have used the mattress with a suitable foundation to qualify for warranty coverage.
Only original purchasers are eligible for warranty coverage. Claims should be submitted to the original dealer, along with proof of purchase. Additional terms may apply.
