Description

Upgrades don’t have to cost an arm and a leg, and the new and improved Ultra Cooling Gel Memory Foam Mattress triples cooling performance to upgrade your quality of sleep without breaking the bank or a sweat. Redesigned from the very first layer up, this new mattress delivers three times more cooling benefits than our standard cooling gel mattress- perfect for sweaty sleepers. So how did we fit so much cooling performance into this new mattress? Supportive base foam is topped with a layer of cooling gel-infused foam to regulate your body temperature for an even cooler night of sleep. Meanwhile our patented 7-zone ventilation system in the top layer allows for better airflow plus the benefit of pressure relief in just the right spots. We wrap all this extra “coolness” in a Cool-to-Touch Soft-Knit cover to add even more ventilation. This performance fabric delivers a cool to the touch feeling to cool you down while you sleep but never chilly. And with our premium green tea infusion now in every layer, this mattress ships nice and fresh to your door- and stays fresh every night after. With our 10-year warranty, unbeatable price and improved construction, this upgraded mattress is the “coolest” choice you’ll make.

    • Unmatched Comfort and Cooling - Best Sleep Ever!
I recently upgraded to the Zinus 14 Inch Ultra Cooling Gel Memory Foam mattress, and it has been a life-changing experience. From the very first night, I noticed a dramatic improvement in my sleep quality. Pros: 1. Ultimate Comfort: The multi-layered construction of this mattress provides exceptional comfort and support. The top layer of ultra-cooling gel-infused memory foam conforms perfectly to my body, relieving pressure points and ensuring a restful night's sleep. 2. Cooling Technology: The cooling gel infusion works wonders in regulating temperature. I used to wake up frequently during the night feeling hot and sweaty, but with this mattress, I stay cool and comfortable all night long. It’s a game-changer for anyone who sleeps hot. 3. Supportive and Durable: The combination of high-density support foam and durable base foam offers excellent support for my back and joints. I wake up feeling refreshed and free of aches and pains, which is something I struggled with on my old mattress. 4. Motion Isolation: One of the standout features is the superb motion isolation. My partner's movements during the night no longer disturb my sleep, allowing us both to enjoy uninterrupted rest. 5. Easy Setup: The mattress comes compressed and rolled in a box, making it easy to handle and set up. It expanded to its full size within a few hours and had minimal off-gassing, which quickly dissipated. 6. Affordable Luxury: Given its high quality and advanced features, this mattress is incredibly affordable. It offers the kind of comfort and support you’d expect from a much more expensive product. Cons: I honestly cannot find any negatives to mention. This mattress has exceeded all my expectations and has dramatically improved the quality of my sleep. In summary, the Zinus 14 Inch Ultra Cooling Gel Memory Foam mattress is a fantastic investment for anyone seeking superior comfort, cooling, and support. It has transformed my sleep experience, and I highly recommend it to anyone in search of the perfect mattress. Five stars! ... show more

    • Comfortable. Best bed for price!
Color: White Size: King Style: 12 Inch
Comfortable bed for a great price! In 2020, I bought my first "bed in a box", the ZINUS Queen 12 Inch Green Tea Cooling Gel Memory Foam Mattress, medium firm, and was pleasantly surprised how truly comfortable it is, although, despite the "cooling gel", I believe the bed sleeps hot. I remedied this with a cooling mattress pad, which, helped tremendously. Wanting to upgrade to a King mattress, I did my research again with ZINUS. I was very hesitate as it did not have the medium firm that I fell in love with the Queen. After much debate and reading the reviews, I purchased the ZINUS King 12" Cooling Gel MEDIUM mattress, although, not quite as firm as I would like, it is still very comfortable and I have slept well in the past 2 weeks that I have owned the mattress. Immediately, I also purchased a cooling mattress pad as I know it would probably also sleep a little warm being a foam mattress. Overall, I think these past 2 purchases are comfortable, inexpensive and provide great sleep each night. In addition, I had no issues whatsoever with the smell or waiting 72 hrs for the mattress to regain its full shape, which it did. ... show more

    • Very Firm but nice
Color: White Size: Full Style: 12 Inch
The only reason I’m giving 4 stars instead of 5 is that these mattresses are next to impossible to return. This is my first memory foam and it’s not the perfect mattress for me. But it’s not like I can return it. That being said, it’s good enough. But I wish for the price it was perfect. I got the 12 inch. It’s a pretty firm mattress. I’d like a little softer mattress. You don’t sink into this at all so if you like firm, this is for you. I do not wake up with any bank pain though. Probably a hybrid would have been a better choice for me. But I still like it. As for the cooling effect…it does not necessarily feel cool to me. But it’s definitely not hot or warm so I’d say it does the job. The feel of the fabric is nice. And it expanded immediately and fast. For those liking a firm mattress I would say this is top choice. I just didn’t know what I liked but that is not the manufacturers fault and it’s still a lovely bed. Just wish there was an easy exchange policy. But that’s the price you pay for a bed in a box verses an expensive store. I definitely would still recommend this bed. Also to the manufacturer, there was a dead baby ring neck snake in the plastic. Interesting. Kind of gross. Wasn’t touching the mattress thankfully. It was an interesting surprise. But you might want to check your warehouse lol. ... show more

    • Good support while still proving padding
Color: White Size: Queen Style: 12 Inch
As we age, nothing is going to make all the aches and pains go away. For the past seven years or so we have been sleeping on a Tuft & Needle mattress. While we liked that mattress, we had come to realize it was a bit too hard in the initial inch or two of compression to avoid causing increased pain in my hips and shoulders. Moving into a new home necessitated buying two new mattresses and, based on the recommendation of our daughter and son-in-law, we decided to try the ZINUS and see if it would better meet our needs. We found a sale and purchased two queen size mattresses at a very good price. We have not been disappointed. The ZINUS mattress we're sleeping on (the identical mattress in the guest room hasn't been slept on yet) is extremely comfortable. It often takes both of us a while to get used to a new mattress, but we were happy after the very first night's sleep. The mattress provides good support for my back while having enough "give" in the first couple of inches to ease the pressure on (and therefore pain in) my hips and shoulders. We are extremely happy with this decision. ... show more

    • Most comfortable mattress I have ever slept on.
Color: White Size: King Style: 12 Inch
From night one this was hands down the most comfortable mattress I have ever slept on. The box stated that I needed to open it within 72 hours. I left it boxed up for a couple of months but it unfolded and expanded quickly. Smells amazing. I highly recommend this mattress.
