In this article we are going to review another excellent sleeping solution from Zinus, a set that includes the Night Therapy Spring 12 Inch Euro Box Top Mattress and a SmartBase. As always, Zinus has done a great job producing a high quality set that is available on the market for prices much lower than average. A full bedding solution such as this one can cost you over a thousand of dollars. However, with Zinus you will get exceptional quality and a full, healthy sleeping solution for less than 800$. Choosing a mattress is a difficult task that includes considering the quality, comfort and the budget. Therefore, keep reading to find out whether this solution is a good option for you!

The Mattress Layers

Within its 12 inches of thickness, this mattress has four separate layers plus additional fiber quilted material in the cover. Going from top to bottom, the first layer is a 1.5” layer of comfort foam, after which comes another 2 inch layer of comfort foam as well. The double comfort foam layer ensures ultimate quality and coziness of the bed. Beneath these two layers is a thin, 0.5 inch layer of high density support foam and, finally, the last layer is the base 7.5 inch layer of pocketed iCoil springs.

The Quality of Materials and Certifications

As with all Zinus mattresses, the foam used in the Night Therapy 12 inch Euro Box Top Mattress is CertiPUR-US certified for finest quality, durability and performance. This certification confirms that this deluxe mattress is of such quality that it can be compared to similar mattresses on the market which go for over a thousand dollars. The cover of the mattress is made of knitted jacquard, with additional microfiber quilted fabric for a soft touch and enhanced comfort. As far as the springs go, they are durable and conform to your body shape easily.

The second item included in the set is the Night Therapy SmartBase mattress foundation platform or bed frame. This bed frame is included in the price and comes with four headboard and footboard brackets, allowing you to attach both a headboard and a footboard to it, thus bettering its appearance and quality. This bed frame provides great support for the mattress and sleeper, as well as adds style to your room interior, while replacing the need for a traditional box spring. The bed frame is 14 inches high, giving you 12.5 inches of under bed storage space for convenience. The durable SmartBase can also be folded for easier transportation or storage.

How it feels and the Overall Sleep Experience

As far as the mattress goes, it is a great combination of foam and spring layers with an additional fiber quilted cover. This mattress falls under the category of firm mattresses because of the strong support provided by the springs and the high density foam. These two layers combined with the double comfort foam layer ensure good pressure relief, allowing you to wake up fresher and happier. Thanks to the high quality pocketed iCoil springs, motion transfer is reduced to minimal, which means you can fall asleep more easily next to your restless partner. The firmness of the mattress also ensures proper spine alignment, making this product a healthy choice for a better night’s sleep. In fact, this Zinus mattress is one of the Night Therapy mattresses, which are clinically proven to help people fall asleep faster and sleep better. Therefore, if you have any sleep related issues, a Night Therapy mattress is the kind of product you need to consider.

When it comes to off-gassing, the customers have reported slight odor coming from the mattress when first being opened, which is natural since it arrives wrapped up in vacuum packaging with no air ventilation. Therefore, you can expect little to no off-gassing that fades away pretty quickly. Finally, in terms of edge support, this mattress is definitely more firm in the middle than it is on the edges, meaning it offers average edge support. It will not sink in if you sit or lay on the edges but it also doesn’t have any additional materials in that area to provide extra support. Therefore, the edge support of this mattress is definitely stronger than that of foam mattresses but not the strongest that Zinus offers.

This amazing sleep solution set comes for the price of 661$ in king size, while it is also available in twin, full and queen size, depending on your requirements. One drawback of this set is the fact that it ships in multiple boxes, which means the items may arrive as separate shipments and you may have to wait for separate packages to assemble your set. Speaking of which, the bed frame is easy to assemble and comes with clear assembly instructions. Once you receive your mattress, make sure to open it within 72 hours to prevent damage caused by the vacuum packaging and let it sit for 24 to 48 hours to expand to its full size and original shape. The mattress comes with a 10 year warranty while the bed frame has a shorter, 5 year warranty. There is no specific trial period listed for either of these products.


All together, the sleep solution set from Zinus that includes the Night Therapy Spring 12 Inch Euro Box Top Mattress and a SmartBase is a healthy and clever choice for those looking for a high quality bedding option within a certain budget. For only a little over 600$, you will be getting a high quality firm mattress that offers exceptional comfort and support, as well as a durable bed frame which replaces a traditional box spring. Overall, this mattress provides great pressure relief and proper spine alignment, as it is clinically proven to help improve your sleep in general. Keep in mind that this is a firmer mattress and if you’re not used to that kind of sleeping surfaces, you may find it strange or different than your usually bedding solution. Therefore, if you’re not a fan of firm mattresses, consider getting a memory foam mattress topper as well!
