Review: A Good Bed Makes a Good Difference - I don’t typically write reviews for things I like, or don’t like. If I take the time to write down my opinion it’s generally to complain about truly being disappointed or on rare occasions, like this one, truly amazed. Having my expectations exceeded is a rarity, one in which I’m willing to put my time and words to paper - or screen. This, this is one of those exceptional experiences- and I can’t believe it’s over a mattress of all things. Buying a mattress shouldn’t be hard, but it is. It’s made harder by today’s advertising and BS. We no longer know what the best way is to buy the thing we’ve bought our whole life. Are we being ripped off? The answer is of course yes; but how do we solve that? The answer in this case is Zinus. Perhaps embarrassingly, I put more research into my latest mattress purchase than I did my last car. Maybe because it’s such a personal purchase and one you live with for such a long period of time. What you sleep on, and how you sleep, matters. A decade ago I bought my last mattress. It was a good mattress. It was very expensive. It served me well… for a few years. I extended it’s life far past it’s usefulness by adding memory foam and padding and then again by telling myself it was sufficient, for years. After at least a year of restless nights which I attributed to other causes I finally admitted to myself I needed a new bed. What a pain, literally. This began my research into what to buy and from where. If you’re looking at a Zinus then you’ve undoubtedly looked at the other major players in this category. They’ve sprung up all in the last couple of years because of one major reason - mattress sales are a scam. Unfortunately, so are online mattress sales for the most part. After a lot of research which you can do in your own time using Google, nearly all these ‘online mattress companies’ are actually made in the same factory using nearly identical material. They all add in their own exclusive features but they are mostly the same. The major difference being the name on the box it’s shipped in. Zinus is considerably cheaper than the rest. It is nearly identical to the rest. It’s cheaper because they lower their markup. It really is that simple. The big players in this game pretend to offer a great deal but then markup their mattress by 300% or more. Ask yourself why they can afford to let you sleep on it for 3 months, then pay someone to come to your house and take it to the landfill if you don’t want to keep it. They would literally rather pay someone to throw it away than to take it back. That’s how inexpensive it is for them to make them. The markup is so much that their product becomes disposable. This doesn’t mean they are bad mattresses. In fact, all those name brand online retailers sell great mattresses, nearly identical to the Zinus. They are just incredibly overpriced. Now my review - my mattress rant is over. I hope some find it useful. I bought the ‘Zinus Memory Foam 12 Inch / Premium / Ultra Plush / Cloud-like Mattress, King’. With it I also bought the platform bed from Zinus - also because of the incredible price and which I’ll also review. (spoiler, it’s fantastic) The mattress comes compressed in a box of course. That’s how it works. Unlike some other manufacturers it fully uncompresses and is ready for sleep on day 1. There is no chemical smell because it’s not treated with the same nasty chemicals that some other manufacturers put on theirs. I’ve read a lot of ‘explanations’ from the other makers as to why they fill theirs with chemicals, none of which are convincing. My guess, is so that they can sit in warehouses for years and not get moldy. This is without a doubt the most comfortable mattress I’ve ever slept on. If it’s comfortable to you will of course depend on what your definition of comfort is. Zinus makes several different mattresses in varying degrees of firmness. I just happened to luck out buying the right one for me the first time, I think. This one is firm, but giving. It’s the kind of mattress where I can roll around on one side and it doesn’t effect my partner on the other side. You don’t feel movement unless it’s right up against you. At the same time it gives slightly, making it very conforming to your body. One of the most important things to me as a person who is generally hot all the time is that it stay cool, and this does. I didn’t realize it until I got this mattress but I believe one of my issues for such a long time, was being hot. I get no heat from this mattress at all. As an example of just how comfortable this mattress is, having not slept in it yet, I also purchased a very expensive and beautiful down mattress topper along with very beautiful, thick, luxurious sheet set. Ultimately I ended up sending all that back because honestly sleeping on the mattress itself with no other bedding under me save a thin fitted sheet is unbelievably comfortable. You’ll want as little as possible between you and the mattress. I’m not sure what I can say that would be more complimentary than that. I’ve had the mattress for a few months now and it really has been life changing. Not in a ‘save the world’ kind of way - but it has saved my sleep. I sleep well, and for the first time in years. A good bed makes a good difference. I’ve been a tad evangelical about this review only because it’s made such a positive improvement in my life- and for far less money than the alternatives. A few tips: Put your mattress on a VERY firm surface. This isn’t your old traditional mattress, you do not want it on a bed springs. If you can’t buy a platform bed now, put it on the floor. Do not add a bed topper even though your experience with your old mattress may incline you otherwise. Sleep as close to the mattress as you can. No topper, thin sheets. If you don’t believe you can buy a great mattress for hundreds less, buy the more expensive ones first (I did). There is no risk in comparison. Those other brands let you send it back within 90 days at no cost. Buy it, send it back, then buy the Zinus and compare. You can also easily send this back. I’d be absolutely shocked if anyone says they went with the more expensive brand after a comparison. I’m glad you spent the time to read this review. Now, do your research, compare, and buy this mattress. Review: Better than a pillow top - Update: I already own this mattress but love it so much I bought one for the ‘guest’ room at my parents... mainly because I stay with my parents when I’m in town for work and sleep in my childhood bedroom where my parents put their older queen sized mattress that would literally leave my back in the worst pain, was sinking in the middle and just uncomfortable. Maybe I’m more concerned with myself and my comfort, regardless, I bought the 10” queen version of this mattress for Christmas (for my parents but more for me when I’m here) to replace the current... which is where I’m laying and typing this updated review. I’m going to sleep so good tonight. Also, I’m not that selfish... I bought my parents nice things aside from this mattress lol ——————— I bought the 12” full — I don’t know what it’s like to sleep on a cloud but if I could imagine sleeping on its heavenly goodness, this bed is it. It is SO comfortable and I actually sleep solid through the night and I don’t even feel my dogs walking on it as they like to move around during the night and it used to wake me. That top layer is just squishy goodness but underneath lies all the support. Prior to this bed I had a pillow top Serta perfect sleeper, it was a great bed and served its purpose but this bed is better because you don’t have to deal with coil springs. Some people have mentioned an odor... which I did not encounter the first day but after about 2 days I did notice it, however, I figured out what it’s from. The mattress itself is foam and needs time to air out and rise like a loaf of bread because it is delivered compressed. I had my mattress on the floor which doesn’t allow for maximum air flow or the air to flow through/escape as needed... so when I lay on the bed, essentially my body weight is forcing the air back down through the mattress and trapping it not allowing for things to air out or escape anywhere. My advice would be to order base/platform when you order the mattress or before so you can roll your mattress out on it and allow the air to escape as needed to really air out. Unfortunately I ordered mine after (Zinus 18inch smart frame) but UPS delivered it to the wrong address, so I missed out and have been waiting a week for the whole turn around process of getting another. It’ll all work out. This bed is worth it, like I said... make sure it’s on an elevated base to allow ample airflow. I’m hoping the smell will go away once I get it on the platform. ## Features - Elastic - Green Tea-infused Memory Foam With a Soft, Poly Jacquard Cover - INSPIRED BY NATURE - Wholesome and natural ingredients, like green tea and moisture-absorbing charcoal work wonders in a mattress, and we’ve designed this one to control odors, maintain freshness, and envelop your shape so you awake restored and refreshed - CERTIPUR US CERTIFIED - Highest quality foam is CertiPUR US Certified for durability, performance, and content - PRESSURE-RELIEVING FOAMS – Layers of conforming green tea memory foam and high-density Z:Base foam hug your shape to soothe you to sleep ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #14,482 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #69 in Mattresses | | Brand | Zinus | | Customer Reviews | 4.3 out of 5 stars 57,020 Reviews | | Item Firmness Description | Medium | | Item Weight | 80.1 Pounds | | Product Dimensions | 80"L x 76"W x 12"Th | | Size | King | | Top Style | Smooth Top | ## Product Details - **Brand:** Zinus - **Size:** King - **Product Dimensions:** 80"L x 76"W x 12"Th - **Item Weight:** 80.05 Pounds - **Item Firmness Description:** Medium - **Top Style:** Smooth Top - **Cover Material:** Jacquard - **Number of Layers:** 3 - **Fill Material:** Memory Foam - **Weight Limit:** 500 Pounds ## Images ![Zinus 12 Inch Ultima Memory Foam Mattress, King, Fiberglass Free, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, White - Image 1](https://m.media-amazon.com/images/I/71Ax+nGZRDL.jpg) ![Zinus 12 Inch Ultima Memory Foam Mattress, King, Fiberglass Free, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, White - Image 2](https://m.media-amazon.com/images/I/71P0q8qeKfL.jpg) ![Zinus 12 Inch Ultima Memory Foam Mattress, King, Fiberglass Free, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, White - Image 3](https://m.media-amazon.com/images/I/71d-t0AILCL.jpg) ![Zinus 12 Inch Ultima Memory Foam Mattress, King, Fiberglass Free, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, White - Image 4](https://m.media-amazon.com/images/I/71w5-Mzdz7L.jpg) ![Zinus 12 Inch Ultima Memory Foam Mattress, King, Fiberglass Free, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, White - Image 5](https://m.media-amazon.com/images/I/81FihdQvnzL.jpg) ## Available Options This product comes in different **Pattern, Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A Good Bed Makes a Good Difference *by D***. on October 15, 2017* I don’t typically write reviews for things I like, or don’t like.

I went to Sam's Club, Mattress Warehouse, Bedding Barn, yadda yadda, and tried a million different mattresses. All of them were lovely, but none of them were cheap. Is this bed stellar? I wouldn't call it that. But it is a wonderful bed for someone who really doesn't want to spend much more than 200$ on a mattress, and someone who certainly doesn't want to try to haul a huge ass mattress on the top of her little Ford Fiesta. PROS - 1. Cheap. 2. Cheap. 3. Cheap. Seriously, where the hell else are you gonna get a decent mattress for this price? 4. It comes to your house in a box. You open the box, open a bunch of bags, and the mattress gloriously unfolds for you. After having moved sofas and tables and desks and lamps into my apartment, it was MAGICAL to have something normally so bulky arrive and take pretty much zero work to set up. 5. It's a good mattress. I've had it for almost a month now, I sleep well, there's no noticeable comfort issues. Many of the negative reviews I read mentioned that it was too firm, firmer than they were expecting. I think that's because when people think memory foam, they think Temperpedic. See the con section below for more on that, but given all of the complaints about the firmness I was pleasantly surprised with the softness of it. It's firmer than I like, but it does kind of contour to your body. Also, unlike Temperpedic, this mattress doesn't trap all of your body heat! I hate waking up sweaty so this was a huge plus. CONS - 1. Smallest con ever: it smells funny for like, 10 minutes after you get it. Really not a big deal though. 2. Do not expect this mattress to be a Temperpedic. If you've done any research on mattresses, you'll know that cheaper memory foam mattresses use a cheaper, different density foam than the fancy ass Temperpedics. (If you haven't done research yet, I suggest the Sleep Like the Dead website.) The skinny on these mattresses is that they run firm. And yes, this bed is firmer than I prefer. But see the PRO section above for why this doesn't matter to me that much. 3. Now I don't know this first hand, but I have heard that there's really not much you can expect in the way of customer service from this company. And honestly, if you order a bed-in-a-box like this, open it and find out 2 weeks later you really don't like it, what are you going to do? You can't ship it back, because there's no way you can squeeze the mattress back into the box. So I'd suggest trying out a bunch of mattresses, making sure that you're okay with something like this, I would say softer than a firm pillowtop, but firmer than a high density memory foam mattress like Temperpedic. Be REALLY sure you want to buy this before you place an order. ALL IN ALL - This is a good, budget mattress. Generally speaking with mattresses you get what you pay for, but I would say this is a really good deal. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/5062188-zinus-12-inch-ultima-memory-foam-mattress-king-fiberglass-free](https://www.desertcart.vu/products/5062188-zinus-12-inch-ultima-memory-foam-mattress-king-fiberglass-free) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-10*
