The Sleep Master mattress is high in comfort and great on affordability. Many people who have purchased this mattress were incredibly satisfied with its performance, as evidenced by its average rating of approximately 4.3/5 stars. The Sleep Master mattress comes in a handful of the standard mattress sizes, including Twin, Twin XL, Full, Queen, and King. The variety of choices means you’ll definitely be able to find a mattress size that is suitable for you and your sleeping needs. It only comes in a medium firmness, which is generally the sweet spot for those who are fans of plush or firmer mattresses. This mattress performs very well thanks to its multi-layers of foam that helps to provide support for your body and stability for the mattress as well. What’s great about the Sleep Master mattress is that it comes with an excellent 10-year warranty, which will ensure that your investments are protected. Perhaps, the best thing about this Sleep Master mattress is its quality and affordability. In terms of bang for your buck, it might be harder to find a mattress that packs this much into it at such a reasonable price.

Layers and filling

The layers and filling greatly contribute to the firmness of a Sleep Master mattress. And while it only comes in medium firmness, there are quite a few different layers that help to make this a very comfortable product. The top layer of the mattress is a 2-3-inch memory foam layer. This layer is probably the most important one because it touches your body. It is designed to reflect the contours of your body to ensure an optimal sleeping position. Below this layer, you will find a 2-3-inch comfort foam layer that also helps to absorb your body weight and offers more support. The bottom layer of the Sleep Master mattress is a 4-6-inch, high-density base support foam that helps stabilize the entire mattress and provides overall reliability.

Thickness and firmness

In terms of thickness and the firmness, there are 6, 8, 10, or 12-inch options available. When it comes to thickness, a thicker mattress can be the difference between a great sleep and a bad one. Having one that is sturdy and can withstand the weight of your body while keeping you comfortable is essential. You can find different combinations of the sizes and thicknesses with the Sleep Master mattresses. However, all of them are medium-firm, which makes it the best of two worlds.

Motion transfer

Motion transfer is another important feature of the Sleep Master mattress in that it does a great job of minimizing its impact on your sleep. If you happen to sleep with a partner, you’ve probably experienced some issues when the partner moved or shifted around, and it woke you up. With the Sleep Master Mattress, you’ll be glad to know that these mattresses do a fantastic job of reducing its impact on your sleep. Thanks to its 4-6-inch thick high-density foam, the Sleep Master mattress doesn’t really affect your sleep when someone moves around in it. You’re more likely to wake up if they were to jump up and down repeatedly on the mattress, but for normal movements, you’re going to sleep without getting disturbed!


The noise is similar to motion transfer, and it refers to the sound a mattress will or will not make when someone moves during the night. If you’ve ever had a mattress that creaks after each moment you make, you wouldn’t want to ever hear that noise again. Luckily, the Sleep Master mattress does an excellent job of minimizing the noise in the bed. This is because of the memory foam layers that help to avoid any sounds from your movements.

Temperature regulation

In terms of the temperature regulation, mattresses tend to either be hot, neutral, or cool. The Sleep Master mattress is more on the neutral side. If you sleep in a very warm room or in much more humid climates, you can expect that your mattress will remove any heat to prevent you from sweating. Therefore, it provides optimal sleeping conditions, and you won’t wake up during the night.


While the inner layers many mattresses may be excellent, all of that could go to waste if the cover layer is not comfortable for you. Fortunately, the Sleep Master mattress uses a marvelous and luxurious polyester cover material. In fact, it is actually a knitted jacquard fabric, which is a blend of polyester and cotton. Those two materials combined produce a very soft yet elegant cover that is also washable. You can remove the cover using the zipper that wraps it all the way around.

Inflation time and smell

Like any new product, it can smell exactly of that, a new product! This Smart Master mattress is no different – it has a smell of a new mattress, that was just fine for some people but for others, they complained that it smelled like chemicals. If the scent is too strong for you, one reviewer recommended unpacking the mattress in a room with opened windows and let it sit there for a few days. As for its inflation, since its top layer is memory foam, the Sleep Master mattress will probably need anywhere from 24-48 hours to fully inflate and return to its natural shape.

Edge support

One of the things the Sleep Master mattress could improve on is its edge support. While it’s not terrible because of its medium firmness that won’t allow you to completely sink while you’re sitting on the edge, this Sleep Master mattress does lack any sort of solid and durable edge support. Other mattresses can have its own layer that wraps all the way around the edge of the mattress, but, unfortunately, this one does not have that. Still, it shows impressive results for a memory foam mattress.


Sleep Master Mattress ReviewIn terms of durability, the Sleep Master mattress offers you a real good product that should last you for years. With three impeccable memory foam and high-density foam layers, your back and your entire body will benefit from a great night’s sleep. Moreover, if you do find that you’re having issues with its durability, you can take advantage of Sleep Master mattress’ 10-year limited warranty.


If you’re one who looks for particular certifications with mattresses, the Sleep Master mattress is certified by CertiPur-US for their usage of formaldehyde-free, low-emission foam. That means the foam is made using no chemicals and is also very dust-resistant. Another great here is that that these mattresses meet the smoldering cigarette test (16 CFR Part 1632) as well as the Open Flame Test, or the Federal Flammability Standards (16 CFR Part 1633). This certification ensures that this Sleep Master mattress is graded high on durability, performance, and materials used.


Like many mattresses on the market, the Sleep Master mattress comes with a 10-year limited warranty. However, unlike some other models, it does not come with a trial period. A trial period usually lasts about a month, and it allows customers to return the product with no charge if they don’t like it.

Price tag

Price can often be a key consideration in any big purchase, and the same can be said for mattresses too. If you’re particularly price-sensitive, you’ll be very happy to know that the Sleep Master Mattresses are incredibly affordable. To give you an idea of their amazingly low price, you can get the Twin XL for about $130, the Twin for $145, the Queen for $190, the Full for $265, and finally, the King for $335. Other mattresses, you can easily cost over $1,500 for one, but with these Sleep Master mattresses, they really are a bargain.
