Here I’ll be reviewing the Zinus 12-inch Green Tea mattress.
I’ll go over the firmness of the bed, what it’s made of, run some tests, compare it against some other popular mattresses, and finally give my pros and cons at the end of the review.
The main feature is that green tea and moisture-absorbing ActivCharcoal are infused into memory foam, which is CertiPUR-US Certified for durability, performance, and content.
Another advantage is an affordable price tag, but more on that later in the article.

The first thing I like to take a look at when I’m reviewing a new mattress is the support level of the bed.
I would say the Zinus 12-inch Green Tea mattress is about 5 out of 10 on the firmness scale.
I generally think of most mattresses as having 6.5 as a medium firmness, so this is definitely to the softer side.
There’s a lot of memory foam in this mattress, which means you’re going to sink pretty far into it.
We’ll take a closer look at the materials a little bit later on in the review.
I will say because of that memory foam, I find myself sinking into the mattress. I’ve laid down on my back and I was sinking pretty deep into the mattress.
Something else that I notice is that because of the memory foam, it did trap a little bit of body heat. It did sleep a little bit hot.
If you are someone that tends to overheat during the middle of the night, you might want to be careful with a memory foam mattress such as this.
As I roll around, change positions, memory foam has a slow response to pressure, so you may feel a little bit stuck.
It’s a slow moving in the layers as you’re changing positions on this mattress. There’s not much bounce to it at all.
One thing that I did notice is that as I was lying on my side, you’re able to sink deep into the mattress.
That’s great for side sleepers because it helps you avoid the formation of pressure points on problem areas like the shoulders and the hips, which can be problems for a lot of side sleepers out there.
The opposite is true for the stomach sleepers who tend to need a firm mattress to support the hips from sinking into the mattress.
I would not recommend the Zinus Memory Foam mattress to the stomach sleepers out there.
Instead of just taking my word on the feel of the Zinus Green Tea mattress, I’d like to run a few tests to give you a more objective look at what this bed is all about.
First up is the pressure map portion of the review.
Just like it sounds, I put a pressure map down on top, lie down in a few positions. The results range from blue for low pressure to red for high pressure.
On my back, my weight is evenly distributed. It’s blue across the board. It’s pretty much what I was expecting and I see out of most bed-in-a-box mattresses. It’s good to see that it is performing up to standard here.
I will say that I did feel myself sinking into the mattress, that contouring around my body, that memory foam is known for, even on my back.
When I roll onto my side, this is where we see a lot of mattresses spike into the yellow or even red range if they’re a bit too firm for side sleepers.
I was really impressed by the Zinus Memory Foam. It’s mostly blue! A little bit of green at the hips, but that’s not too bad. I’d still say that that’s within the acceptable range.
When testing on the pressure map, again, this mattress is a really good choice for the side sleepers out there.
Rolling onto my stomach, weight is evenly distributed like I was on my back. It’s going to be blue, low pressure, across the board here.
However, I would say that I felt my hips sinking into the mattress in this position. If you are a strict stomach sleeper or someone who spends a portion of their night on their stomach, you’re going to want to be careful of softer mattresses such as this.
The next test that I like to run is a bounce test.
It checks to see how much mobility a mattress is going to provide.
If you are a combo sleeper, someone who rolls around, changes positions during the middle of the night, you don’t want to feel too stuck in a mattress.
You don’t want to feel you’re fighting the layers to change positions, cause you to wake up and adjust yourself in the middle of the night.
This is a soft memory foam mattress. You’re going to sink into it. I definitely felt the slower response to pressure of that memory foam.
It doesn’t have any bounce to it, because it doesn’t have any springs or coils. It’s an all-foam mattress.
If you are someone who likes to feel more on top of the bed, you’re not going to get that out of this mattress.
If you’re somebody that likes to sink in deep into a plush feeling mattress, the Zinus 12-inch Green Tea Memory Foam is going to give that to you.
Another test that I like to run that goes hand in hand with that bounce test is a motion transfer portion of the review.
Basically, I put a seismometer down on one side of the bed where you might be sleeping.
That seismometer is going to track how much disturbance is transferred across the bed.
To test that, I dropped a 10-pound steel ball from the heights 4, 8, and 12 inches.
That simulates, if you share your bed with a partner, how much disturbance is going to be felt on the other side of the bed, if they are getting into and out of bed, rolling around during the middle of the night.
I was impressed with the Zinus’ ability to isolate motion transfer.
Because of the thick soft layer of memory foam on top, it does a really good job of dulling that disturbance transfer across the bed.
If you are someone who shares your bed with a bit of a restless sleeper, this can help you sleep through the night.
To give you a better idea of what’s going on with the Zinus Green Tea Memory Foam mattress, I’ve opened it up to see the layers of the mattress.
First of all, the cover is a thin polyester cover. It’s nothing too special there. It is pretty thin, so that should help with breathability though.
I do want to point out that I’m testing the 12-inch version of the mattress. This mattress does come in 6, 8, 10, and 12-inch versions.
How that affects feel?
I would guess the 12-inch is actually the plushest feeling.
With this one, we have on top a really thick layer of memory foam. This is three inches of memory foam. You’re going to sink right into that.
You can see that slower response to pressure.
Memory foam is known for being great at pressure relief, because you get to sink in. You get that contouring feeling around your body.
One thing that I will warn, though, is that memory foam has a reputation for trapping a bit of body heat.
If you are someone that tends to sleep a bit hot, you might want to be careful with memory foam in general.
The Zinus infuses green tea and ActivCharcoal into the foam to neutralize odor and absorb moisture.
Below that, we have a layer of poly foam, which is acting as a transition layer. It’s a firmer layer. It’s got a quick response to pressure, some bounce to it.
It’s transitioning you from that soft comfort layer of memory foam into the support of the mattress.
The support of this mattress is made of two 3.5-inch layers of high-density poly foam, so a total of seven inches of high-density poly foam at the base.
It’s a really firm material. It’s a common material in a lot of bed-in-a-box mattresses. It supports layers of foam on top of it and gives the mattress its shape.
If you’re checking out this review, I’m assuming that you’re also looking at a few other mattresses online, so I want to compare the Zinus Memory Foam against a few of its biggest competitors.
First up is the Tuft & Needle, which is another all-foam bed in a box.
It has a firmer feel than the Zinus mattress does. It uses a Tuft & Needle foam, which is their propriety material. It has a quicker response to pressure than memory foam.
I would say it does a really good job of sleeping cool. I like the Tuft & Needle for the back sleepers out there. In terms of price, it ranges from $350 up to $750 for the king-size version.
Next up is the Nectar mattress, which is another all-foam bed-in-a-box mattress.
This one uses memory foam in a similar way to the Zinus that we’re looking at here. It has a really soft feel that allows you to sink in. It’s great for side sleepers. I also like it for the couples out there.
In terms of price, it ranges from $399 up to $899.
Before I end the review, I want to give you my pros and cons for the Zinus 12-inch Green Tea Memory Foam mattress.
First up, reasons I would recommend it to you is if you are a side sleeper. I like the soft feel.
You can sink into bed and avoid the formation of pressure points at the shoulders and the hips, two problem areas for a lot of side sleepers.
I would also recommend it to the memory foam lovers out there. If you like the feeling of sinking into bed, that contouring around your body, this is going to give you that classic memory foam feel.
Finally, I was impressed with the Zinus’ ability to isolate motion transfer.
If you are someone who shares your bed with a restless sleeper, it’s going to help dull the disturbance transfer across the bed and help you sleep a little bit more through the night.
Some of my complaints with the Zinus Memory Foam mattress include that it lacks bounce.
Because it is an all-foam, memory foam mattress, you’re going to sink in.You may feel like you are a little bit trapped in layers when you’re trying to change the position.
If you are someone that likes to feel more on top of the bed, you may want to find something
that’s more along the lines of an innerspring or a hybrid mattress.
I would also say if you are a stomach sleeper, this is probably not the best choice for you, because of its softer feel.
I felt my hips sink into the mattress, threw my spine out of alignment.
You’re going to want to find something with firmer support to keep those hips from sinking too far into bed.
I will also say that I found that memory foam trapped a little bit of body heat. If you are someone who tends to sleep a little bit hot through the night, you might want to stay clear of memory foam mattresses in general.
If you are interested in purchasing a Zinus Green Tea Memory Foam, I want to give you some of the basic information on the purchasing process.
First up, shipping is free.
It will arrive compressed in a box, so I recommend letting it decompress for a few hours or even overnight before you sleep on it to get the full support and feel of the mattress.
This item is non returnable
In terms of warranty, it comes with a 10-year warranty. I would say that’s about the industry standard for the all-foam bed-in-a-box mattresses out there.
In the terms of price, it ranges from $217 up to $441 for the Califonia king-size version.
Here are some of the most frequently asked questions about Zinus mattresses to help you decide whether it’s the right choice for your bedroom.
Is Zinus a good mattress?
Yes, Zinus makes a wide range of nice mattresses. The most popular model is their Green Tea memory foam bed and it is a classic memory foam mattress. It’s available in a range of heights from 6 to 12 inches.
Do you need a box spring with a Zinus’s mattress?
Like many bed in a box options, Zinus’s mattresses don’t need box springs beneath them to comfortably support the sleeper. During my review I tested the memory foam mattress on a slatted bed frame. I think that will be enough for most people.
Can you sleep on a Zinus mattress before 24 hours?
This is a question I get asked a lot about mattresses that arrive compressed in a box. Basically, when you open the box, you’ll find the mattress compressed in plastic rap and rolled up for easier shipping. When you open the plastic wrap, air will rush in and expand the foam layers.
Just because the foam has expanded and the mattress has started to take shape doesn’t mean the bed is at its full height and support level. I generally recommend people allow their newly unwrapped mattresses to decompress for at least a few hours before they sleep on it.
Another thing people may notice when they unwrap a bed in a box mattress is a distinct smell, known as off gassing. It’s really common to have a bit of a smell since the bed has been in a vacuum sealed plastic for a while. If it’s a big problem for you, I’d recommend opening the windows while the mattress is expanding. And definitely don’t put sheets on the bed until you’re ready to go to sleep.
Can you flip a Zinus mattress?
This is a really common question that I get a lot and the answer is no. You can’t flip Zinus mattresses. Like most mattresses designed today, it has firmer layers on the bottom and softer comfort materials on top so you can transition from pressure relief to support as you sink further into bed. If you are worried about wearing out your mattress too quickly, I would recommend rotating it 180 degrees every six months.
How long does a Zinus mattress last?
It’s tough to give an exact lifespan on all Zinus’s mattresses, because different models are made with different materials, which can break down at different speeds. Not to mention that different sleepers put different wear and tear on mattresses because of how actively they roll around or stay in one place throughout the night.
All Zinus mattresses are backed by a 10 year limited warranty. But in realistic terms, I would say you should probably change out your mattress every 5 to 7 years.
Is a Zinuss mattress good for back pain?
Picking the right mattress for avoiding back pain can be tricky because it really depends on what type of sleeper you are. The most important thing you can do when looking for a new bed to fight back pain is find the right level support for your sleep style.
If you’re a side sleeper, that means something soft enough to let your shoulders sink in for pressure relief, while keeping your spine aligned in a good position. For back sleepers, something in the medium firmness range. Stomach sleepers should definitely go with something a bit firmer to keep the hips up and the back in good alignment.
Why does Zinus use green tea?
Memory foam has been used in mattresses and other types of furniture for decades now and people love its body contouring and pressure relieving abilities. But it does have a few drawbacks, chief among those negatives is that memory foam has a tendency to trap heat and because of this it can start to get a bit of a sweaty feel to it.
Many companies that use memory foam use different types of infusions to help their mattresses sleep cooler. Zinus uses green tea extract infusion to help maintain freshness in their mattresses.
That’s it for my review of the Zinus 12-inch Green Tea Memory Foam mattress.
