    Overview

    Experience next-level sleep comfort with the Zinus Ultra Cool Gel Memory Foam Mattress—an advanced sleep solution designed to deliver targeted support and all-night cooling relief. This thoughtfully engineered mattress features a triple-layer cooling system, including pressure-relieving gel-infused memory foam, to create a refreshing sleep surface that adapts to your body’s natural contours.

    The standout feature is its 7-Zone comfort layer, strategically constructed to support the unique shape of the human body. Each zone offers a different level of firmness to cater specifically to the head, shoulders, torso, hips, and legs—providing balanced pressure relief exactly where it’s needed most. This zoned design works independently across your body to ensure optimal spinal alignment and personalised comfort throughout the night.

    Encased in an ultra-soft, breathable Air-Cool knit cover, the mattress promotes airflow while offering a plush, gentle touch. Beneath the surface, Zinus' proprietary Green Tea Support Foam enhances the sleep environment with hypoallergenic and odour-resistant properties—ideal for sensitive sleepers seeking a cleaner, fresher rest.

    Whether you’re a hot sleeper or simply seeking superior comfort and support, the Zinus Ultra Cool Mattress delivers a cooler, cleaner, and more restorative night’s sleep, night after night.
    7-Zone Support System

    Engineered with seven distinct zones that provide softer support for shoulders and firmer support for hips and knees, enhancing alignment and overall comfort.

    Cooling Gel-Infused Memory Foam

    Regulates temperature and draws heat away from the body, ensuring a cool, comfortable night’s sleep.

    All foams certified by CertiPUR-US®

    Meeting the CertiPUR-US® standards for being made without ozone depleters, PBDEs, TDCPP, TCEP, mercury, lead or other heavy metals sometimes found in foam. Additional to the contents, the emissions and durability are analysed by independent, accredited testing laboratories.

    Pressure-Relieving Foam

    Layers of high-quality memory foam contour to your body, reducing pressure on joints and supporting natural spinal alignment for improved sleep posture.

    Not for me
    I have to start the return process, this is the worst sleep I’ve ever gotten. My back pain is though the roof and I need to switch back to my previous mattress that had a huge divot and two springs broken.

    Good Cooling But Way Too Firm
    I’ve had my ultra cooling mattress for about a month now. I’ve paired it with linen sheets for extra breathability and feel like it does a great job at not getting too hot while I sleep. But so far that’s been where the positives have ended. The mattress is very very firm. I thought it might take a little break in period but a month and some change in and it’s still brutally firm. Im a side/slight stomach sleeper and I’ve noticed that since getting the mattress I wake up feeling tired still and I have had pain in my back that definitely wasn’t there before. I’ve ordered a topper for it to hopefully bring some relief for my sleep but overall I’ve been pretty let down by the mattress. I can’t say I’d recommend it and unfortunately will probably be avoiding Zinus as a brand moving forward.
