First, let’s take a look at the background and credentials of the Zinus company.

Brand background

The company Zinus was formed in 2004, and by 2006, they had released a proprietary compression packing method. The method allowed them to efficiently ship their products in a new and unique way, leading them to be revolutionaries in the “bed-in-a-box” market.

Zinus invented several new technology-based products in the memory foam and gel space, including their proprietary BioFoam.

Zinus is about two key things: innovation and affordability. Each of their products is unique in some way, but everything is affordable and fits right in line or exceeds anything else you’ll find on the bed-in-a-box market.

The Zinus Ultima Comfort Memory Foam Mattress can be purchased in thicknesses of 8, 10, or 12 inches and in bed sizes from twin to king. We’ll be highlighting the 8-inch option today.

It’s important to note that each level of thickness will come with its own ratio of the foam layers that we’ll discuss below, and the listed levels of thickness for each individual layer will come from our focus on the 8-inch version.

Layers of Zinus Ultima Comfort Memory Foam 8-Inch Mattress

Now, we’ll examine each layer of the mattress, from the cover down to the support base.


The cover of the Zinus Ultima Comfort Memory Foam Mattress is made of soft knitted jacquard fabric, meaning that the textured pattern is woven into the mattress itself instead of printed on the surface.

The cover should not be removed to be washed and can be spot-cleaned if needed.

Comfort Layers

The ratios of the various types of foam are a bit part of what makes this mattress an outstanding choice; it is designed and engineered to perfection.

Underneath the knitted jacquard cover lies two inches of luxurious memory foam — the perfect amount to let your body sink in just enough to feel right at home.

Beneath the initial layer of memory foam is two inches of trademarked Comfort Foam, which is infused with the aforementioned and proprietary BioFoam. This ensures that instead of the traditional petroleum included in the foam, there is some natural plant oil to keep your mattress fresh and eminently comfortable.

Support Layer

At the bottom of the mattress, beneath the combined four inches of memory foam and Comfort Foam is another four inches of material.

This four inches is entirely made of high-density base support foam. It is much thicker than the layer above, almost resembling an egg crate. The high-density nature of this foam allows for much more rigid support, ensuring that the cushier layers of foam won’t have too much give.

That said, it’s still foam, so it gives enough to keep this mattress ultra-comfortable. You’ll feel like your sleeping among the clouds, instead of just lying on top of them.

The Zinus Ultima mattress also performs adequately when it comes to the edge test. The edge test is a measure of how well the mattress holds up when someone is sitting on the perimeter of the bed for an extended period of time — or if you’re pushed to the edge by a child or pet that jumps in the middle of the bed during the night.

The amount of high-density foam that supports the entire mattress is conducive to impressive edge support, too, so there are no worries there.

Our Test and Reviews


This mattress is a 7 out of 10 on the firmness scale. While memory foam mattresses are known for sleeping firm, the combination of memory foam and Comfort Foam allow for just a bit more give than folks who typically sleep on more traditional, purely memory foam mattresses might be used to experiencing.

Sleep Hot

While many memory foam mattresses sleep quite hot, we’re happy to report that you won’t experience that discomfort with the Zinus Ultima Comfort Memory Foam 8-Inch Mattress.

The aforementioned BioFoam that is infused with natural plant extracts allow for a cooler foam that doesn’t retain quite as much heat as traditional memory foam. That’s good enough to get this mattress an 8 out of 10 — outstanding for a mattress that is entirely made of foam layers.

Motion Transfer

The Zima Ultima Comfort Memory Foam 8-Inch Mattress fits with a long line of memory foam mattresses that handle motion extremely well.

The density of all three layers of foam — especially the high-density base layer that has four inches of the extra-dense foam — gives this mattress a 9 out of 10. You’d be hard-pressed to find a mattress that handles unwanted motion better than this one.

Is the Zinus Ultima Comfort Memory Foam Mattress right for you?

  • If you have a restless bed partner or your kids are constantly jumping into bed with you, then you need a mattress that is highly-rated in the motion transfer category. And that’s the Zinus Ultima.
  • Looking for an affordable, memory foam-based mattress to provide the perfect combination of support and comfort while not sleeping hot? You’re in the right spot.
  • If you’re sold on getting a “bed-in-a-box” and avoiding shopping in a furniture store, then the convenience — and free shipping — of this Zinus product is right in line with what you’re looking for.

Final Thoughts

Overall, the Zinus Ultima Comfort Memory Foam 8-Inch Mattress is a top-flight pick when it comes to a mattress that is both comfortable and affordable, with supportive memory foam to boot.

The extremely soft, comfortable cover and the two inches of memory foam beneath it will cradle your body as you fall asleep. You’ll sink just enough into the two inches of Comfort Foam beneath the top layer, as your body is supported enough to avoid painful pressure points but sinks enough to allow for complete relaxation.

The four inches of high-density foam on the bottom will help your mattress hold shape and stay true to form as you enjoy years of perfect sleep.

And don’t forget just how affordable this mattress is, clocking in at under $300 for the king size and under $200 for all other sizes.

If you want a firm memory foam bed with a little bit of give that doesn’t sleep hot and will arrive right to your door, all at an unbelievable price, than look no further. The Zinus Ultima Comfort Memory Foam 8-Inch Mattress checks all of those boxes — and then some.
