One of the most important and natural things to do in life is sleeping. Of course, we all want to get the best sleep possible. It doesn’t have to be so difficult: the only thing you are supposed to do is to lay down and close your eyes. Yet, in order to get a good night sleep (and be fresh in the morning) we all need one important thing, a good mattress. Mattresses make a huge difference on your sleep: they dictate if you wake up refreshed or not. Having a bad mattress can cause you problems with your back – you’ll have to deal with the pain. Because we care about your health and your sleep, we decided to make a review of one of the best rated memory foam mattresses on the market, the Zinus Sleep Master Ultima Comfort.

The pioneer in the mattress industry is Zinus, Inc. They are committed to provide their customers comfort and support at an affordable price. The company provides us with a memory foam option that offers pressure relieving comfort, high density base support form and durability. The materials used in this mattress are certified by CertiPUR-US meaning that no harsh chemicals were used during its production. Thus, both you and the environment are safe. To keep the mattress at optimal parameters for longer, Zinus avoided the use of petroleum, by using a Bio Foam natural plant oil.

For those who have problems with allergies, the memory foam has in its structure and density less dust mites compared to other mattresses and can have even less when you add a hypo-allergenic cover made especially for mattresses.

The Zinus Sleep Master Ultima Comfort can solve your back and hips problems thanks to the properties of the memory foam. The materials used for removing the odor come as a plus in the favor of your health.

It’s very easy to use, they recommend to open the package within 72 hours and leave it for 48 hours to return to its original form. After that, it’s good to go.

Zinus Sleep Master comes available in three profiles: 8 inches, 10 inches and 12 inches. Some of the customers said that the 10 and 12 inches mattresses are more soft to medium vs the 8 inch which is more medium to firm. Zinus has some other great models besides Sleep Master like, Spa Sensation, Night Therapy and Slumber One. As for sizes, the mattress can come in queen, king, California king, short queen, full, twin xl and twin.

What is it made of?

This Zinus has three separate layers of foam: three inches of memory foam, three inches  comfort foam and 6 inches of support foam with a high density base.

The first layer creates a level of softness and is the layer that adapts to the body. The second layer has the job to relief your body from pressure and reduce pain. The thrid and last layer supports the upper layers of foam and retains the mattress’s shape. This base helps on the durability and overall comfort of the mattress. The cover is made of high quality fiber and foam. This brings an extra layer of support and softness to the mattress, while also reducing the level of heat retention. In this way this Zinus mattress achieves breathability.

Before you decide on buying a mattress, you should pay attention on the firmness, comfort, paint relief and support, off gassing and intimacy. If you were also wondering if the Ultima Comfort Mattress will be compatible with your bed frame, the answer is yes. The only thing that you should pay a bit of attention is that your bed should have a solid frame. Also the slats have to be no more then 3 inches apart, and to be constructed of wood or metal.

The Sleep Master has a great shipment program; depending from where you buy it, they send it from the manufacturer directly to the consumer. This brings the cost of the mattress down and you don’t have to deal with other stores. The disadvantage is that you can’t test the mattress before you buy it. In this way you are not really sure if it’s comfortable and if it gives the support they say it will provide. Kind of tricky.

Trial period, guarantee and warranty

Trial period: The company doesn’t offer a trial period for this matters, but you can return it in 30 days, with some additional fees.

Guarantee: There is no definitive guarantee and if you wish to return the mattress, it will come with some charges.

Warranty: Comes with a 10 year warranty and if you experience some defects as a result of faulty manufacturing, you can contact the company and they will either repair or replace your mattress.   


One of the top competitor for the Zinus Sleep Master mattress is Signature Sleep. Both mattresses offer comfort and support for all the average sleepers. A small difference is that the Sleep Master has a longer durability than the Signature Sleep mattress.

Another competitor is Tempur Pedic; again, both of the mattresses are all covered of foam, but the Sleep Master is much more affordable than Tempur Pedic.


Overall we believe that this memory foam mattress offers a medium comfort and support for the average sleeper. It comes with a CertiPUR-US certification and has no motion transfer or off gassing. If you are questioning yourself whether the Zinus Sleep Master Ultima Comfort Memory Foam Mattress is right for you or not, check out our list of the most important aspects. One of the things you should appreciate is the fact that is more affordable than other foam mattresses that you can find on the market. Others refer to the fact that it brings comfort and support for a good night sleep.
