Set name: Gel 12 inch
I couldn’t be happier with this mattress—it completely exceeded my expectations! The copper-infused cooling gel memory foam really does make a difference, keeping me cool and comfortable all night without that overheated feeling I’ve had with other memory foam mattresses. The medium-firm support is just right: soft enough to contour to my body and relieve pressure, yet firm enough to support my back whether I sleep on my side or back. I also appreciate the thoughtful 3-layer design, which feels both plush and supportive, and it works perfectly with my bed frame. Knowing it’s made with CertiPUR-US certified foam and an OEKO-TEX certified cover gives me peace of mind about safety and quality. Overall, this mattress delivers incredible comfort, support, and value—I’ve been sleeping better than ever and would highly recommend it!

We recently purchased the Essential 12-Inch Copper Infused Cooling Gel Memory Foam Mattress, and it has exceeded our expectations! The mattress offers the perfect balance of comfort and support—medium firm without feeling too hard. It provides excellent pressure relief, and I wake up feeling much more refreshed with less stiffness! Setup was simple, the mattress expanded quickly, and there was very little odor. Overall, this is an amazing value for the price and has significantly improved our sleep quality. Highly recommend!

Absolutely love this mattress! I was honestly surprised by how comfortable it is for the price. It has the perfect balance of softness and support — soft enough to feel cozy, but still supportive enough that my back doesn’t hurt when I wake up. The mattress expanded quickly after opening and didn’t have a strong smell like some memory foam mattresses do. I’ve been sleeping so much better since switching to this one. It also feels very sturdy and doesn’t sink too much even with two people sleeping on it. Overall, great quality, comfortable, and worth every penny. Definitely recommend if you’re looking for a supportive memory foam mattress without spending a fortune!

It’s comfy and not firm at all. I have to say that we already had half the mattress for this topper, which is shown in the picture under this 8 inch mattress topper. It’s definitely not 8 inches. We let it sit out for around 24 hrs and it raised to around 6 inches. That seems to be what most others have confirmed after buying as well. So to sum this up: DO NOT buy this as a mattress. This is definitely more of a mattress topper. But as a topper it is comfy and I do like it better than our previous 4 inch foam topper we had before this. It’s softer and less firm than what we had before. For the price it is well worth it for a mattress topper!!

I've been using this Essential 12" Cooling Gel Memory Foam Mattress (King Size) for several weeks now, and I'm very happy with my purchase. The medium-firm feel is exactly what I was looking for. It provides excellent support while still being comfortable enough to relieve pressure on my shoulders and hips. I used to wake up with occasional back stiffness, but I've noticed a significant improvement since switching to this mattress. The cooling gel memory foam also seems to help regulate temperature throughout the night. I tend to sleep warm, and this mattress feels noticeably cooler than my previous memory foam mattress. Overall, this mattress exceeded my expectations for the price.

UPDATE 2: This seller processed a refund immediately after I updated my review detailing their refund runaround with screenshot of their messages. Coincidentally, my review was then reported and removed. So I am resubmitting it again because customers need to know that this behavior is happening, its unacceptable, and it should be weighed against the tons of "good" reviews for this mattress, which I am not convinced are genuine. If the review is removed again, I'll submit my own report for an investigation into the current reviews that all sound exactly the same and may not be genuine, which is a violation of Amazon seller policy. UPDATE: This seller sent me a message offering me a full refund for the horrible experience I've had with this mattress. When I agreed, they then say they couldn't do a refund but that they would offer me a replacement. I said no and explained that I am aware of how the Seller backend works. They said they would have to reach out to Amazon support to see if there was an alternative method for remitting a refund and would "get back to me." This was 21 days ago, and I haven't heard a word from them. I am an e-commerce director and have come across the refund bait and switch before, offering a refund and then changing it to a replacement so they don't have to give you the money back because in the end, the mattress costs less than what the sale price is. They lose less money vs the refund and still keep the customer quiet. Now, whether what this seller is saying is true or not, I can't say. They sent a PNG that could have been a screenshot of something but it wasn't openable on our end. So who knows. I can only go by what I know from experience. What I can say is that it is possible to remit a refund well past 30 days. END of Update. Had this mattress for 9 months. It sinks terribly after 10 minutes of laying on it. The sinkhole is so bad, I'm completely arched. I have back pain galore. My posture has been ruined. My neck and shoulders always look like I'm some kind of goblin. And I feel like one when I crawl out of this bed. You have to crawl out of the hole. When you get up, you can see the massive sinkhole. There is no support whatsoever. I allowed more than the 72 hour wait period before using it. I allowed it to expand for 5 days. After 3 days, the corners still hadn't expanded. But I was able to get them to expand. The memory foam has no support. It is a true king size and fit my bed correctly. But the quality is horrible, and I'm starting to think most of these reviews are not genuine or authentic. I do not recommend this bed to humans or any vertebrates in the world. Your spine will do unnatural bends and curves while laying on this. I do not know what I did in life to deserve such a bad bed.

Honestly, getting this new mattress was such a clutch move for my apartment. Setting it up was super easy since it comes shoved in a box (though it’s kind of heavy, so definitely grab a roommate to help carry it up the stairs), and it didn’t have that weird, gross factory smell right out of the plastic like a lot of cheap foam beds do. It's honestly the perfect middle ground—super comfy when you faceplant into it after pulling an all-nighter, but it doesn't totally swallow you whole, so your back actually gets some solid support. It also stays nice and chill all night, which is a lifesaver because nobody wants to wake up sweating in a stuffy bedroom, and the bed is so steady that it barely even shakes if someone else is tossing and turning. If you're looking for a thick, massive upgrade from a trash dorm bed without totally draining your bank account, this one is 100% the move.

Recently, I received my king size gel memory foam mattress from Lifement. This mattress provides good support to the back and neck. This mattress is for my son. He loved it. This is thick, durable, springless mattress. Definitely I would recommended this mattress if anyone looking for it.
