What you get with the Zinus Cooling Gel mattress

Zinus is known for producing affordable mattresses, bed frames, and other sleep products. They have two memory foam models: the Pressure Relief Green Tea mattress and the Cooling Gel mattress. While both models offer 5 different size options with 4 different firmness levels, the Cooling Gel mattress sets itself apart with a layer of foam infused with gel to absorb heat.

Zinus Foam Mattress Review

The Cooling Gel mattress is made with CertiPUR-US® certified foam and consist of anywhere from 2 to 4 layers depending on the firmness level chosen.

A few key characteristics of the Zinus memory foam line that make it a popular choice are:

  • Affordability: Zinus offers high-quality mattresses at some of the lowest price points in the industry.
  • Motion isolation: If you share a bed with a restless sleeper, this fits the bill, as it performs well in this category.

These are the potential weaknesses of the Zinus memory foam mattresses:

  • Durability: With the firm mattress at 6” of thickness total and just 5” of the higher density base foam, you shouldn’t expect the longevity of the thicker, heavier mattresses on the market. Products and materials manufactured in China often have less quality control than in the US.
  • Cooling: Memory foam mattresses, including Zinus, aren’t the best option for warm sleepers. The gel in the newer Cooling Gel model will create initial coolness, but without a route to conduct heat away from the sleeper, the gel will eventually warm.
  • Expansion: Some customers mention that the mattress does not expand to the specified size or takes quite some time to do so.

About Zinus

Brand history

The company was founded in 1979 and expanded to the US in 1984. Zinus is based in Asia with a U.S. Sales and Marketing base in California. Zinus, Inc., encompasses many other mattress brands, such as Night Therapy, Slumber 1, and Sleep Revolution. Mattresses are manufactured in China, with 3 distribution facilities in the US and 1 in Canada.

The Zinus manufacturing facility in Xiamen, China, is a vast operation with over a million square feet of space for production. Retailers for Zinus-made mattresses include Wal-mart, Costco, and Amazon. Zinus mattresses are available directly from their website, and the Green Tea memory foam model is available on Amazon at this time.

Brand reputation

Zinus has earned an A+ rating from the Better Business Bureau. More information about BBB and its mission is available online.

Although you’ll find some negative press for the company online, the great majority of customer reviews of the Zinus brand mattresses are satisfactory. The Amazon reviews are specifically for the Green Tea mattress. Out of nearly 11,000 reviews there, 74% customers rate the mattress at 5 stars.

Customer feedback

Both positive and negative reviewers note that the mattress cover should not be removed to wash, so adding a cover would be advised. Here are some of the other customer-cited pros and cons:


  • Comfort
  • Pressure relief
  • Support (reviews trend on the firm side)


  • Quality of the cover material
  • Need for a solid platform base to prevent sagging
  • Customer service (specifically the lack of delivery information after the product was purchased)
  • Too firm

A look at the Zinus Cooling Gel mattress

The Cooling Gel memory foam model is distinguished by a layer of gel-infused memory foam, called “swirl foam” by the company. This layer ranges from 2” to 4” in thickness and is designed for heat absorption. The ingredients used in the gel are not made readily available by the company.

Zinus Cooling Gel Mattress Layers

Aside from the layer of gel-infused memory foam, the mattress is composed of a knitted jacquard cover, a layer of memory foam, and a base support layer of high-density foam. While the firm mattresses stop there, the medium-firm and plush options, which increase in thickness from the 6” firm up to the 14” plush, include one or two extra layers of high-density foam for added cushion. The base support layer ranges anywhere from 3.5” to 6” depending on the chosen thickness .

Zinus Green Tea Mattress Review


Like other bed-in-a-box mattresses, the Zinus Cooling Gel mattress will be compressed, vacuum sealed, and delivered to your door in a box. The box should be opened, and the mattress removed immediately. The mattresses are compatible with any base, but the platform base is recommended. For an adjustable base, the company recommends either an 8” or 10” mattress.

The company is clear that the mattress cover should be left on and is not to be removed for washing. Like other memory foam mattresses, the Cooling Gel mattress is not designed to be flipped over and rotating is optional.

All Zinus mattresses are manufactured in China.

How the Zinus Cooling Gel mattress performs

Motion isolation

Zinus exceeds expectations in this area. The Cooling Gel mattress includes a 3”-top layer of gel-infused foam on top of other foam layers, which means those sleeping with a restless partner are not likely be disturbed on a Zinus foam mattress.

Edge support

Foam mattresses don’t excel when it comes to edge support, in particular for heavier sleepers, and with the use of lighter-weight foam, Zinus is no exception. A foam mattress can’t compete with coil in this area.


There’s always a price to pay for affordability, and while Zinus competes well on comfort, it shouldn’t be expected to compete with the high-end brands on lifespan.


The Zinus memory foam mattresses rate at a 6 out of 10 for firmness as a group, placing them in the medium-firm range. You do have a wide range of thickness options, and thousands of customers who opted for the plusher 12” models report satisfaction.


The body contouring aspect that foam mattresses are known for typically creates a warmer sleeping experience. The Cooling Gel mattress should help, but it’s not clear in company specifications if the gel foam includes the needed perforation to allow heat to escape. If not, the gel layer will start out cool but eventually reach maximum absorption.


The majority of customer comments note little to no offgassing, even in the early days, making this an area of strength for Zinus.


The Cooling Gel model contains a 3” layer of top foam. Combine that with the base layer of high density foam, and you have a mattress designed strictly for motion absorption and a comfortable sleep. As a result, this area is not an area of strength for this mattress.

How to take care of your Zinus Cooling Gel mattress

Zinus does not publish care guidelines for their mattresses on the website, except to say that the mattress cover is not washable. Follow the standard procedures for cleaning and maintaining any memory-foam mattress when caring for your Zinus mattress.

  • Never soak a memory-foam mattress with any liquid.
  • All spot-cleaning should be done without the use of harsh chemicals.
  • Use mild detergents mixed with warm water or a vinegar-and-water mixture to lightly sponge the affected area.
  • Vacuum all sides regularly using a brush attachment.

This mattress cannot be flipped, but rotating regularly is advisable. When moving your mattress, be careful to lift rather than drag to protect the cover as well as the foam.
