Zinus is one of the most popular mattress manufacturers on the market, offering their products at extremely affordable prices. If you’re wondering how they are able to cut the prices so much, that is because all Zinus products are manufactured in China and shipped directly to the buyer’s door, which means there are no middlemen or distributors of any kind. However, don’t be fooled by the fact that the products are made in China, since they are still very high quality and you definitely get a lot of bang for your buck. In this article we are going to review the Zinus Sleep Master Ultima Comfort 8 Inch spring mattress.

The Mattress Layers

As a fully spring mattress, this product consists of only two layers. The bottom layer is a 7.5 inch layer of hundreds of pocketed iCoil springs that provide support and ensure less motion transfer. On top of it is a thin, one inch layer of comfort foam, just so you’re not directly on the springs. The top layer also includes a foam and fiber quilted cover, which adds a bit of comfort as well. We are currently reviewing the 8 inch Sleep Master Ultima Comfort mattress while you can also get it in 10, 12 and 13 inches. Keep in mind, the thicker the mattress, the more comfortable and soft it is. Therefore, the 8 inch version is the firmest you will get.

The quality of material and certifications

As usual, even though there is only little foam used in this mattress, all foam layers from Zinus are CertiPUR-US certified for good performance, great durability and natural content. Other materials of the mattress include high quality iCoil pocketed springs and a foam and fiber quilted cover. The cover is breathable and helps regulate heat. It comes in white color with the plain design. When it comes to the quality of materials, it is guaranteed that Zinus chooses only the best!

How it feels and the overall sleep experience

As we mentioned above, this is a purely spring mattress with only one inch of comfort foam, which means it is exceptionally firm and supportive. The iCoil springs provide customized support to your body and ensure minimal motion transfer, as they are wrapped individually. The fact that there is no motion transfer means you can sleep peacefully even with a restless partner. The firm support of the springs keeps your spine aligned which is crucial for a good night’s sleep. This helps relieve pressure and helps you get rid of back and neck pain, which is why many customers find this mattress favorable. Thanks to the natural materials Zinus uses in its products, there is only little to none off gassing at all. While in general this mattress provides great support and exceptional comfort, we must remind you that it is very, very firm. If you’re not a fan of firm mattresses, then maybe this product is not the best option to go with.

The thin layer of comfort foam on the top allows you to sink slightly into the mattress while the coil springs do the rest. After months and years of use, customers have stated that this product doesn’t get lumpy and doesn’t sag over time. That means the mattress is highly durable, as it doesn’t change shape and stays firm even after a few years of being in use. Unlike most memory foam mattresses, the Zinus Sleep Master Ultima Comfort provides great edge support, so if you like sleeping near the edge of the bed or sitting there, this mattress will do a great job supporting you. Another thing customers are satisfied about regarding this Zinus mattress is that there are no lumps or unevenness on its surface that may cause discomfort. With this product you will be able to get a good night sleep and feel fresh and relaxed in the morning!

As we already mentioned, you can get this mattress in 8, 10, 12 and 13 inches thickness, the thicker it comes, the softer it is. Since we are reviewing the 8 inch one, or the one that provides maximum firmness, it comes at the price of 161$ in size Twin XL. Of course, the pricing will vary according to the size you choose. The product is smartly shipped directly to your door. As it will come compressed in a box, it is recommended to take the mattress out within 72 hours of receiving the package to prevent it from getting damaged. Keep in mind that it will take some time for the mattress to fully expand and return to its original shape. Even though there is no trial period specified for this product, you can still call the manufacturer within 30 days of purchase to discuss having it returned but keep in mind that extra fees may apply. On the positive side, the product does come with a 10 year worry free, limited warranty for all manufacturing defaults. As we mentioned in the beginning of this review, the product is shipped directly from the manufacturer to your door, which means you wont get a chance to try it out before you buy it. Hopefully our review will give you an idea of what this mattress feels like.


All together, the Zinus Sleep Master Ultima Comfort 8 inch spring mattress provides maximum firmness and exceptional comfort, especially for those who prefer sleeping on firmer surfaces. If you’re looking for a medium firm or a softer mattress, then this option may not be the best one for you. The reason why you should consider choosing Zinus is because you wont be able to find such high quality products for such affordable prices anywhere on the market. When it comes to affordable pricing, Zinus is truly a one of a kind manufacturer. Even after a few years of using this mattress, the customers have reported back with great reviews, stating that the mattress stays firm and does not change shape over time. Therefore, for such a low price you will be getting maximum firmness, great comfort for a good night’s sleep and a durable and long-lasting product to enjoy in!
