Our testers found that the OkiFirm’s graphite-infused memory foam does a good job of reducing motion transfer, particularly when compared to other firm (8) foam mattresses.
However, the firmer foam doesn’t tend to absorb motion as well as softer memory foam might. This means that sleepers who are sensitive to their sleep partner’s movements may experience interrupted sleep more on the OkiFirm than they might on a traditional memory foam bed.

Pros
Cons
The OkiFirm mattress is the firmest of OkiOki’s four mattress models. Standing at 10 inches tall, the mattress rates 8 out of 10 on our firmness scale. With a supportive design featuring a 3-inch graphite memory foam layer and a 7-inch polyfoam core, the OkiFirm works particularly well for back and stomach sleepers.
OkiOki has three other mattresses. The OkiEasy and OkiFlex are hybrid mattresses that use a combination of memory foam and pocketed springs to provide good support for a wide range of sleepers. The OkiSoft is a softer all-foam mattress that works well for side sleepers.
We’ll explore the OkiFirm Mattress in greater detail, taking a closer look at its performance characteristics for different kinds of sleepers. We’ll also discuss pricing, sizing, and shipping policies. Read on to see if the OkiFirm is the best mattress for you.

Answer a few questions to find the right mattress for your unique needs
Sleeping Style and Body Weight
Side Sleepers
The best mattresses for heavy sleepers tend to be firm, while lighter sleepers often prefer a softer feel. Our side sleepers weighing more than 230 pounds appreciated the firm (8) feel of this mattress and felt they got a good balance of support and pressure relief. The OkiFirm’s strong pushback helped them avoid the “stuck” feeling that can result from softer mattresses with deeper contouring.
However, the side sleepers on our testing team who weigh less than 230 pounds felt the mattress was too firm and lacked the usual “hug” of an all-foam mattress. The best mattresses for side sleepers generally feature close contouring and pressure relief, which can help keep the spine aligned. Those who need this kind of support may prefer a softer mattress that conforms more closely to the body.
Back Sleepers
During testing, the OkiFirm performed well for back sleepers weighing more than 130 pounds. These sleepers found that the OkiFirm offered enough responsive pushback through the torso to keep the hips and shoulders from sinking too deeply into the mattress. This helped relieve pressure and improved spinal alignment.
However, the mattress was too firm for our back sleepers weighing less than 130 pounds. These sleepers usually need a somewhat softer mattress that offers enough give to comfortably support the hips and lumbar region.
Stomach Sleepers
The firmness of the OkiFirm worked well for the stomach sleepers on our team. The extra support kept them from sinking too far into the mattress, which can create pressure points and result in aches and pains.
The OkiFirm worked best for our stomach sleepers weighing between 130 and 230 pounds. The graphite foam and high-density polyfoam combination lifted their hips and chest to support a healthy alignment.
Stomach sleepers under 130 pounds also responded positively to the OkiFirm’s subtle contouring and significant support, although some sleepers in this category may find the OkiFirm a touch too firm. Our testers weighing over 230 pounds also gave the OkiFirm good reviews. It is worth noting, however, that stomach sleepers in this weight category may experience slight sinkage around the stomach, making it harder to maintain proper spinal alignment.
Mattress Performance
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.

OkiFirm Mattress Review Breakdown
The OkiFirm Mattress has a 10-inch profile and an all-foam construction. Three inches of high-grade graphite memory foam make up the comfort layer. This foam’s porous composition allows air to pass through, which helps with temperature regulation. A 7-inch layer of high-density polyfoam forms the OkiFirm’s support core. All together, these layers give the mattress a firm feel of 8 on the 10-point firmness scale.
The mattress’ cover is made with phase change material that wicks heat away from the sleep surface. This, combined with the tiny air holes in the graphite foam layer, are designed to help the OkiFirm sleeps cool, particularly compared to other all-foam models.
Shoppers can select from six sizes, including twin XL to California king. OkiOki recommends pairing the OkiFirm with a mattress foundation if the OkiFirm will be used on a metal bed frame. A compatible version is available for purchase for all six mattress sizes. A box spring or a bed frame with slats will also work.

Mattress Prices and Sizing
The OkiFirm mattress has a lower price-point than many other all-foam mattresses. This makes it a good choice for value-seekers who enjoy the pressure relief of a foam mattress but also need something on the firmer side. In addition to the standard sizes, it also comes in twin XL and California king.
