What Makes It Great?

Zinus thought outside of the box when they developed this mattress topper. Have you ever heard of a mattress with green tea or charcoal? Now you have! Here are a few other features we love about the Green Tea Memory Foam mattress topper:

  1. Fresh and Clean: Excuse us while we repeat ourselves—we’re pretty jazzed about the proprietary green tea and charcoal blend infused into this topper’s memory foam. Charcoal is known to eliminate moisture, and green tea blocks smelly odors.
  2. Easy on Your Body: This memory foam is decidedly soft and easily conforms to your body when you lie down. It eases pressure off of your joints and bones, which alleviates and even prevents muscle aches and stiffness.
  3. Thickness Options: You can choose from three different thicknesses—an inch and a half, three inches, four inches. This range accommodates all sleeping positions and comfort preferences.

Inside the Zinus Mattress Topper

full mattress topper best green tea infused

Zinus uses the same foam in their Green Tea mattress topper as they do in a handful of their full size mattresses, including the Zinus Green Tea mattress, Cooling Gel Memory Foam mattress, and Memory Foam iCoil Hybrid mattress.

The BioFoam is made mostly with plant oil from the castor bean. It cuts down on the use of petroleum-based products that can cause off-gassing.

The inch and a half version is a single piece of green tea memory foam, but the three inch and four inch versions have an additional two to two-and-a-half piece of high density support foam on the bottom.

The topper doesn’t have a quilted fabric cover like the Zinus mattresses, but it fits nicely under deep-pocket fitted sheets.

Sleep Experience

Side Sleeping

The main priority for side sleepers is pressure relief and spinal alignment. Without both, back pain inevitably develops, since joints and bones take the brunt of your body weight. With that said, the three inch Zinus mattress topper should provide adequate pressure relief. You’ll likely sink pretty deep into the foam, so heavier weight sleepers may want to size up to the four inch version.

Back Sleeping

Back sleepers are the flexible middle child of the sleeping positions. They need a little support and a little comfort, but fare pretty well if they lean in one direction or the other. For example, the three inch version of the Zinus topper will balance out the firmness of an innerspring mattress. Alternatively, the inch and a half version could add the extra oomph needed to make a medium-firm mattress a little more cozy.

Stomach Sleeping

Stomach sleepers need a supportive mattress surface, so their lower back doesn’t arch out of alignment. This usually translates into a firmer mattress topper, and some may even benefit from just a mattress pad. At the same time, they do need a little pressure relief for their ribs and hips. 

The Zinus mattress topper feels really squishy, according to customers, so the inch and a half thickness is the best fit for stomach sleepers, although heavier weight sleepers may need the three inch version to get the same cushioning effect. The four inch version is likely to cause lower back pain, so it should be avoided by stomach sleepers.



  • Affordable: Zinus mattress toppers are some of the most affordable on the market—on par with other value brands like Lucid and Linenspa. Luxury toppers from brands like Tempur-Pedic will cost you three or four times as much.
  • Pressure Relief: The foam used for the Zinus Green Tea Memory Foam mattress topper is designed to eliminate high pressure zones on your body and make you feel like you’re weightless.
  • Cost Effective: Using an extra layer of memory foam extends the lifespan of an old mattress or enhances the comfort of a new mattress, which saves you money in the long run.
  • Freshness: Active charcoal and green tea extract in the foam have a cleansing, antimicrobial effect that neutralizes odors.


  • Temperature: Memory foam tends to retain warmth, which can cause you to overheat in the middle of the night.
  • Availability: Some topper sizes or thicknesses aren’t always in stock. If you don’t see your size on the Zinus website, check Amazon or another authorized retailer.

What is the best mattress topper you can buy?

Generally, side sleepers need a softer feel, and back and stomach sleepers need a medium-firm or firm feel. If you want to transform your mattress, or if you’re heavier, opt for a thicker topper. The material is a matter of preference. Choose from foam, latex, cotton, wool, down alternatives, etc.

Why does my Zinus mattress topper smell?

Memory foam is manufactured with materials that contain “volatile organic compounds” (VOCs). When VOCs break down, they emit an odor called off-gassing. The odor is non-toxic, but if you want to be cautious, shop CertiPUR-US certified foams and let your mattress air out for three to seven days first.

Do you put the flat side or the egg crate side down with a Zinus mattress topper?

Some mattress toppers have a convoluted side, which is a fancy way of saying it looks like an egg crate. This side should face down. The waves in the foam increase breathability. The channels made by the grooves improve airflow, so heat doesn’t stay trapped in the foam.

Should You Buy It?

The Zinus Green Tea Memory Foam topper checks a lot of boxes on the average shopper’s “must have” list: cushioning, conforming, affordable, and customizable by thickness. It can run a little warm, so if you get especially hot at night, take a look at the Swirl Gel Memory Foam Convoluted mattress topper by Zinus. It’s designed with grooves on the bottom that act as outward channels for warm air. The gel-infusion also has a cooling effect
