Zinus is one of the best mattress sellers in the US thanks to the quality of the products they offer at available prices. All products from Zinus are directly shipped from the manufacturer to the buyer, without any distributor or middleman, which is why they are able to offer such low prices on them. However, because of this you are not able to see how the mattress actually feels and whether it is the right choice for you. That makes the purchasing process quite difficult but we are here to help you out by making these detailed reviews. In this review we are going to be talking about the Zinus 12 inch gel-infused green tea memory foam mattress, so let’s get into it!

The mattress layers

This mattress from Zinus is available in different sizes, ranging in thickness from 12, 10, 8 and 6 inches. The thicker the mattress is, the softer it feels. This model consists of four separate layers of memory foam for the utmost comfort and support during sleep. The first layer is a two inch gel-infused memory foam layer that conforms to the body of the sleeper and, thanks to its gel component, improves heat regulation significantly. Beneath it is a three inch comfort foam layer that, as the name suggests, adds comfort to the whole combination. Underneath it are two 3.5 inches thick air-flow high density foam mattresses, out of which the bottom one is the base support layer. These two layers serve to add support and firmness to the mattress, making it a comfortable surface for sleeping.

Quality of materials and certifications

As every mattress from Zinus, this model is made of foam layers that are CertiPUR-US certified for durability and performance, as well as for being clean of chemicals and unhealthy components. The cover of the mattress is made of a high quality knitted jacquard fiber, which is breathable and adds softness to the mattress. The fact that the material is breathable enables the mattress to regulate heat better and to stay fresh for a longer time. The memory foam and high density foam of this Zinus mattress are durable and long lasting, while the gel feature adds on to the quality of the materials.

How it feels and the overall sleep experience

The Zinus 12 inch gel-infused green tea memory foam mattress performs exceptionally well for the price it comes at. It provides great comfort and support while staying cool throughout the night. Many people have the problem of heat building up from the memory foam of the mattress that makes it uncomfortable to sleep on. Therefore, the gel infused layer is a feature that many people choose this mattress for, as its heat regulation is superb. The pressure relieving capabilities of this mattress are quite good as well. Due to the softness of the top layer, the pressure points of the body sink into the mattress up to one inch, creating a nice and soft feeling. The bottom two layers of high density foam are there to provide support so that the mattress is not too soft. This combination results in a medium firmness rated 5 on the scale of 1 to 10. The memory foam is also infused with green tea extract and castor natural seed oil, which makes it stay fresh for a longer time and reduces off gassing. The fact that all materials are CertiPUR-US certified and chemical free means the mattress shows little to no off gassing at all. Even though this mattress provides medium firm support, some sleepers may find it too firm for their preference. Overall, the great structure and the quality of the materials in this mattress offer amazing comfort and support, as well as a cool and fresh sleeping surface.

The price of the mattress varies, depending on the size you choose. Most people go for the 12 inch version of this Zinus model, which comes at 299$ in queen size. This insanely cheap price is a great deal for everyone looking for a mattress on a budget but it doesn’t mean the mattress is poorly made just because it is that affordable. The product comes with a ten year limited warranty that covers only the manufacturing errors. As Zinus uses efficient shipping methods to get your order to your door as quickly as possible, your mattress will arrive compressed in a box, which might damage it after a while. Therefore, it is recommended to take the product out of the box within 72 hours upon receiving the deliver, the sooner the better. It may take the mattress up to two days to extend to its full size and regular shape. There is a 30 days free trial specified for this model of Zinus mattresses so, if you decide that this isn’t the right mattress for you, you can easily get your money back if you return the product within 30 days.


Basically, the Zinus 12 inch gel-infused green tea memory foam mattress is the upgraded version of the regular Zinus green tea infused memory foam mattress. Its only drawbacks are the fact that the maximum weight it supports is 550 lbs and that there is not enough edge support. Sitting on the edge of the bed in the morning may not be the best idea and, if you prefer sleeping near the edge of the bed, maybe this mattress is not the best choice for you! All together, this Zinus mattress offers great comfort and support any average sleeper would find satisfying. Some sleepers found it to be too soft, which depends on your personal preference regarding the firmness of the surface you sleep on. Heat regulation is taken care of really well when it comes to this mattress model, as the gel infused memory foam stays cool throughout the night and provides you a better night’s sleep. With the CertiPUR certification, you can be sure that this Zinus mattress is completely safe for use and contains no hazardous elements at all. Overall, it is a great product for the low price it comes at!
