Zinus Lumbar+ Premium Memory Foam Mattress Review: Test Lab Ratings

“Even when team members were moving around a lot on the opposite side of the bed, I didn’t notice much motion.” – Brad

While many all-foam models isolate motion well, the Zinus Lumbar+ Premium Memory Foam Mattress still outperforms a lot of similarly constructed models. Two memory foam layers respond slowly to pressure changes, preventing most motion from transferring. A polyfoam transition layer and core further absorb movement and prevent it from being felt across the full surface.

Motion isolation is usually one of the top things that couples look for in mattress reviews because it can help prevent unnecessary awakenings when one partner moves during the night.

“This bed’s close hug gives that classic memory foam sensation. I didn’t experience any noticeable pressure buildup around my hips or shoulders.” – Logan

Pressure relief is another one of the Zinus Lumbar+ Premium Memory Foam Mattress’ greatest strengths. The medium (5) feel lets the sleeper sink in, while two layers of memory foam respond to heat and weight to mold to their body and redistribute pressure. For side sleepers, this often reduces discomfort around the hips and shoulders.

We used a pressure-mapping pad to visualize the performance, observing even weight distribution across the mattress surface. Team members also noted that they didn’t experience pressure points or hot spots while lying on the mattress.

“I didn’t overheat, but the surface also didn’t feel especially cool. The temperature control was effective but not remarkable.” – Mary

All-foam models with memory foam generally aren’t known for their temperature control, but the Zinus Lumbar+ Premium Memory Foam Mattress performs fairly well comparatively.

Because the Zinus Lumbar+ Premium Memory Foam Mattress’ two layers of memory foam are dense and contour closely to the body, heat cannot air out easily. To counteract that, this model incorporates a cover designed to be cool to the touch and a gel infusion engineered to transfer heat away from the body.

Our temperature readings showed that some heat lingered on the surface, but not a lot. Team members also reported maintaining a comfortable temperature over the course of testing.

“I didn’t feel like I had to stay in the center of the bed, but the perimeter compressed enough that I also wouldn’t sleep along the edges if I could avoid it.” – Brad

The Zinus Lumbar+ Premium Memory Foam Mattress’ edge support was midrange, as we’d expect from most medium (5) all-foam models. Its memory foam and polyfoam compress noticeably when a sleeper approaches the edge, particularly if they weigh over 230 pounds.

None of our testing team members reported that the edge felt unstable enough that they feared slipping off, but they also didn’t feel secure enough to use it extensively.

“Changing positions took some effort, but not enough to limit my movement to a significant extent.” – Mary

Due to its plush feel and close conforming, the Zinus Lumbar+ Premium Memory Foam Mattress does not facilitate movement. Sleepers can sink fairly deeply into the medium (5) surface. Additionally, the memory foam doesn’t regain its shape instantly when they move, so there may be a lingering impression.

While our testers observed some challenges shifting and moving across the surface, they did not report that it meaningfully interfered with their sleep or overall comfort.

“Based on its design, I’d think the Zinus Lumbar+ Premium Memory Foam Mattress should last 6 to 7 years — around average for a foam bed.” – Logan

Based on its design, we’d expect the Zinus Lumbar+ Premium Memory Foam Mattress to have an average life expectancy of around 6 to 7 years, which is similar to other all-foam models. Memory foam can degrade or form lasting impressions over time, which may ultimately impact the comfort.
