However, the downside is that the products cannot be seen or tried out before purchase, as they are shipped directly from the manufacturer to your door. That is why have put together this review to present you all details of this specific Zinus product, a memory foam inch tri-fold comfort portable mattress or floor mat. Read on to find out all relevant information on this product and determine whether it is a good option for you to invest in!

The Mattress Layers

This 4 inch memory foam mattress from Zinus comes with a great benefit, the fact that it is foldable and thus portable and easily stored.  However, it is only 4 inches thick, which may not be enough to permanently support an adult sleeper. We will get into details regarding comfort below, for now let’s stick to the mattress layers. Within its 4 inches of thickness, this mattress contains 3 layers. The top layer is a 1 inch layer of memory foam with 2 inches of viscolatex responsive foam beneath it. The final layer and the base of the mattress is a 1 inch high density base foam for support.

Quality of Materials and Certifications

This is a full foam mattress, meaning there are no other components besides foam. The foam of Zinus mattresses is CertiPUR-US certified, meaning it is durable and long-lasting. This mattress consists of the latest BIO foam, which is a type of foam that contains natural components such as plant oil and green tea extract instead of petroleum and other commonly used chemicals.

The fact that there are natural oils and extracts in this material instead of chemicals means the mattress do not emit odors and that it effectively absorbs moisture to stay fresh and clean for a longer period of time! Besides foam, the mattress also consists of a jacquard cover, which can be removed and washed easily.

How it feels and the Overall Sleep Experience

As you already know, the Zinus memory foam 4 inch tri-fold mattress is an all-foam mattress that provides the memory foam comfort and support. What makes this mattress so great is how convenient yet comfortable it is. Besides providing a supportive and comfy sleeping surface, it can be folded and easily stored or carried. The dimensions of this mattress equal to 78 inches L x 38 inches W. As a mattress made of foam only, this product cannot offer more than average edge support. However, it does offer great comfort as the memory foam layer conforms to your body and help you get a better night’s sleep. Thanks to the natural components and lack of chemicals, off gassing is reduced to little to no odor at all. Keep in mind that this mattress is only 4 inches thick and cannot be used as a permanent sleeping solution for adults.

However, it is a great solution if you need a temporary mattress for a guest room or you simply need a mattress to your trips, whether you’re camping or travelling farther away. If your child loves going to sleepovers often, this mattress would be a great solution for their sleep, as they will be comfortable at a friend’s house like at their own! The mattress doesn’t have any heat regulating layers but since it isn’t very thick, it doesn’t get too warm. Besides, the micro-fiber breathable cover helps regulate the temperature a bit, as well as protects the mattress from wearing and stains. The flexible design of this Zinus mattress allows you to fold it and store it with ease, without damaging the product. If you’re looking for a permanent sleeping solution, this may not be the most comfortable option but as a temporary fix or a backup mattress, it is one of the best products you will find on the market nowadays.

This amazing memory foam tri-fold portable mattress that can be used as a floor mat as well, reasonably priced. When you think about it, this product is really worth the money, since it is a great solution for travelers, kids at sleepovers or those in need of an extra bed for the guests. Unlike most Zinus mattresses which are covered by a 10 year limited warranty, this product comes with only 1 year of warranty, which may be its greatest flaw. There is also no specified trial period for this Zinus mattress but, if you don’t find yourself satisfied with your purchase, contact the manufacturer within the first month to discuss having it returned. Keep in mind that this may come at extra costs. The product is effectively shipped from the manufacturer to your door and it arrives quite quickly. The mattress comes compressed in a box, which is why it is recommended to take it out within 72 hours of receiving the package. Leaving the mattress compressed for a longer period of time may result in damage. It usually takes the mattresses about 48 hours to expand to their full size and shape but since this mattress is only 4 inches thick, it should expand within few hours and be ready for use! Do not use the mattress until it has expanded to its full length and shape.


To wrap it all up, the Zinus memory foam 4 inch tri-fold portable mattress is a high quality solution that comes with an amazingly low price tag. With natural components and great memory foam, this mattress provides good comfort and support as a temporary sleeping solution for guestrooms, camps or traveling. Its only flaw is that it comes with a 1 year warranty, which is certainly much shorter than other Zinus products on the market. Altogether, this tri-fold portable and convenient mattress is really worth the money and, if you’re in need of a product for the above mentioned purposes, Zinus is the right choice to go for!
