Zinus has been in the business of manufacturing and delivering mattresses-in-a-box for over 16 years. The company
The company is always looking to improve and innovate its bedding products. In 2007, Zinus launched BioFoam, a material incorporated with seed oil, green tea, and active charcoal to improve mattress freshness for sleepers. In the following years, Zinus developed more technologies to ensure that its mattresses offer utmost comfort.
Zinus offers both memory foam and hybrid mattress, in a wide variety of sizes and thicknesses. The Zinus 12-Inch Green Tea Memory Foam Mattress is one of two Zinus mattress models with green tea-infused foam. The infusions of green tea and ActivCharcoal help keep the mattress feeling and smelling clean, while the high-quality foam relieves pressure for maximum comfort.
Material and Construction
The Zinus 12-Inch Green Tea Memory Foam Mattress is a well-made mattress featuring several foam materials and a durable cover, with the bonus of natural infusions. This mattress offers multiple foam layers that work together to cradle your body and prevent pain in pressure points.
The mattress comprises 4 layers: memory foam, comfort foam, high-density foam, and high-density support foam. The top two layers of memory foam and comfort foam are the comfort layers, while the bottom two support layers provide sufficient lumbar support.
The top layer of this Zinus mattress is made from 3 inches of premium memory foam. This memory foam layer has a density of 3 lbs per cubic foot, which is a great density rating for the memory foam layer’s thickness. This 
The lower density of the memory foam layer means that the material is made from larger, more open cells. This makes the memory foam softer, so it can yield to your body’s shape more easily. No matter what position you sleep in, this mattress will adjust to conform to your body’s unique contours. The low-density rating of the memory foam also gives the mattress more of a plush feel that side sleepers and stomach sleepers typically need to be more comfortable.
What makes Zinus memory foam unique is that it features infusions of natural green tea extract, ActivCharcoal, and natural plant oil. The natural green tea extract in this memory foam helps keep the mattress feeling fresh and clean, since green tea is a well-known antioxidant. Plus, green tea extract has anti-fungal and anti-toxin properties that make the mattress safer for you to use. ActivCharcoal also helps maintain the mattress’ freshness by reducing odors and absorbing moistures. Aside from green tea extract and ActivCharcoal, the memory foam layer also includes an infusion of natural castor seed oil, which is an antibacterial substance as well.
The second layer of the mattress is made from comfort foam. This foam has a high-density rating. This means the comfort foam layer has more material per cubic foot compared to similar foam materials. More importantly, the high density rating of the comfort foam makes it more efficient at providing pressure relief.
The comfort foam layer and memory foam layer work together to provide the perfect balance of comfort and support. Plus, the high density rating of the comfort foam layer also improves its longevity, which is useful since this mattress is going to see plenty of wear and tear. This 2-inch layer of comfort foam also serves as a functional transition layer between the plush memory foam and the last two foam layers, which are firmer in feel compared to the comfort layers.
The last two layers of the mattress are the support layers. Both layers are made from high-density, convoluted foam.
The convoluted foam in the bottom layers of this Zinus mattress has a high-density rating, so it contains more foam per cubic foot compared to other foam materials. The high-density rating, combined with the ridged design, make the bottom layers more flexible and more responsive than flat foam layers. All these features make the mattress more comfortable and supportive.
All these foam layers have the seal of certification from CertiPUR-US. The certification means that the foam meets industry standards for content, performance, and durability. The foam in this Zinus mattress doesn’t contain ozone depleters, formaldehyde, regulated phthalates, and heavy metals like mercury and lead. The foam is also guaranteed to have low emissions of volatile organic compounds. This helps improve indoor air quality, so the mattress is safer to use.
This Zinus memory foam mattress also comes with a knitted jacquard cover. The thin jacquard cover has a soft, stretchy feel and the fabric is more flexible compared to other materials used in mattress covers. The cover’s sides has miniscule holes to encourage more airflow throughout the mattress and improve overall comfort.
For this mattress, Zinus has used its patented smart technology to compress and roll up this memory foam mattress into a box. This makes it easier for you to put the mattress on your bed base. This Zinus memory foam mattress may take 48 to 72 hours to expand.

Comfort and Ergonomics
The Zinus 12-Inch Green Tea Memory Foam Mattress is designed to consistently give you comfort and sufficient 
You’ll feel how comfortable the mattress is even just touching its surface. The mattress’ cover is made from knitted jacquard fabric. Knit jacquard fabric is generally softer and more flexible compared to woven jacquard. This means the mattress’ cover has a more plush feel that matches the softness of the memory foam layer. Knit jacquard fabric also tends to be more breathable compared to other type of jacquard fabric. This breathability, combined with the small holes on the sides of the mattress, encourages airflow and keeps you cool as you sleep. This is especially useful since memory foam tends to feel too warm for some sleepers.
This Zinus mattress has a 3-inch top layer made from memory foam. This memory foam has a low density rating, so it has more give than high-density memory foam. This means the mattress has a softer, more plush feel. The structure of low-density memory foam features larger, more open cells, making the foam more responsive. This means the memory foam will quickly adjust to your body’s weight as you lie on the mattress. You won’t feel any pushback from the mattress; instead, the mattress’ memory foam layer yields so it can follow your body’s contours.
Another great feature of the memory foam layer in this Zinus mattress is that it distributes weight evenly. Memory foam ensures that your weight is equally distributed along the mattress’ surface. This means no part of your body bears more weight than the others, eliminating pressure points. Usually, the shoulders, hips, and heels bear more weight when you’re lying down, so these get more support.
By evenly distributing your weight, the mattress ensures that your body gets total, all-over support. This also makes this Zinus green tea mattress a great choice for all types of sleepers – side, back, or stomach sleepers. This mattress is even a great choice for combination sleepers.
By conforming to your body’s natural curves, the mattress’ memory foam layer also provides more support for your lower back. This allows your spine to remain in a neutral position as you sleep, drastically reducing the risk of back
Memory foam’s ability to cradle the body and relieve pressure is also an excellent benefit for people suffering from chronic pain conditions like arthritis. The mattress doesn’t place any additional pressure on sensitive areas of the body, ensuring maximum comfort.
The second layer of foam in this mattress also contributes to its overall comfort levels. Together with the other foam layers of this Zinus mattress, the comfort layer cuts down on motion transfer across the mattress. Rather than transferring motion, the foam layers absorb the energy created by movement on the mattress’ surface. This way, you won’t wake up if your partner tends to switch positions often as he sleeps. Your partner also won’t wake up if you shift around in bed all night. With this Zinus mattress, you and your partner will get peaceful, relaxing sleep each night.
Another feature that makes this Zinus mattress more comfortable is the fact that it contains infusions of green tea extract, ActivCharcoal, and natural castor seed oil. Green tea extract and natural castor seed oil work great at neutralizing odors and keeping the mattress as fresh as possible. This way, the mattress will feel brand-new and clean even after years of use.
The ActivCharcoal infusion, made from tiny particles of purified charcoal, absorbs moisture and unpleasant odors. All these infusions come in handy if you tend to get sweaty as you sleep. You’ll be as comfortable as possible whenever you’re sleeping on this mattress.
All-foam, memory foam mattresses have a tendency to feel hot for certain sleepers. This Zinus mattress remedies that by having small holes on the sides of its cover. The holes encourage airflow through the mattress and makes it more breathable.
The ridges and valleys of the convoluted foam also improve breathability and ensure that air more easily flows 
You can also count on the Zinus 12-Inch Green Tea Memory Foam Mattress to offer above-average edge support. The mattress has a slightly firmer feel around the edges, which is great if you like sitting or lying down on the edge of the mattress. You won’t roll off the mattress’ edges, and you’ll be able to maximize the sleeping space on the surface of the mattress.
This Zinus mattress is also made from foam that’s CertiPUR-US certified. The CertiPUR-US seal means that the foam layers in this mattress don’t contain any formaldehyde, heavy metals like lead, and other harmful substances. This makes the mattress safer and more comfortable to use.
Durability and Warranty
The Zinus 12-Inch Green Tea Memory Foam Mattress is designed to last through years of regular use. The mattress features layers of high-quality foam, which ensures that the mattress won’t get worn out compressing when you lay down and expanding when you get up.

With proper maintenance, this Zinus mattress may even last you a lifetime. The infusions of green tea, natural castor 
These infusions go hand in hand with memory foam’s natural antimicrobial properties. The structure of memory foam discourages the growth and accumulation of bacteria and mold. This way, you can rest assured that your mattress’ memory foam layer is as clean as possible. Of course, the foam layers’ CertiPUR-US certification indicates that the flexible foam materials meet industry standards for content and durability.
