ZINUS 8 Inch Ultima Memory Foam Mattress, King, Fiberglass Free, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, White

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.

My old mattress was hard as a rock and hotter than the desert. I was desperate to find a new mattress and I’ve had Zinus years ago. This thing is medium to soft, relieves pressure in all the right spots, but doesn’t cave in like some memory foam. It’s not as soft as I expected, but I think that’s a good thing. The support is great. Not noisy, no motion transfer, looks professionally made. It expanded to 12” in about 10 minutes. I slept on in after about 2 hours and it was perfectly fine. Not “hard as a rock” like others say. I had no odor issue with mine but the box and plastic did have an odor.

I'm writing this in regards to the mattress not just for a regular bed, but a sofa sleeper, as there were hardly any reviews for this set up.At the beginning I was hesitant to go with a 6 inch foam mattress for my sleeper sofa, but I'm glad I did for several reasons (one was a surprise bonus).I saw the recommended 5 inch which was almost $100 more than this one was and I thought this was simply because 5 inch is the typical sofa sleeper size, it's not a better mattress per say. I also thought, hey, this is foam, it compresses, it should fit anyways. I'm glad that I went with the 6 inch. Here's why:1: Less expensive than the 5 inch one recommended. Saved some money, that's always good. 👍2: Base foam is 4 inch instead of 3.5 which makes it a tad firmer, but enough that you don't feel the bars in the sofa, and I mean you don't feel it AT ALL. I was the most skeptical about these claims, but man alive, I'm a believer now. This alone makes it worth every penny. But the top layers are the memory foam and cooling memory foam which helps in the summer months and isn't too bad in the winter. Regardless, it's very comfortable and gives you a tad more memory foam.3: Here's the surprise bonus. You know how the basic mattress sofa sleepers come with give you no support when you sleep, and that transfers to the folded up couch as well? Ours was actually compressing so much in couch mode that it was like sitting in a hole where the cushions for the couch sink in so you felt the wood like a bar under your leg in the front, and were in a small pit to get out. Once we got the new mattress it bulges a bit since its a tad too big which makes the couch extra fluffy. It's now supporting the cushions like it should, and instantly became a comfortable couch. Not sitting in a hole is nice, go figure.Here's my thoughts on a few things that are important to know:1: Yes the cushion does take a full 24 to 48 hours to reach the full 6 inches (closer to 48 hours). After about 24 hours though it's comfortable enough to sleep on and was at about 5 inches expanded. Had to test this out with a guest immediately as the mattress arrived a little over a day before he arrived. The guest loved it by the way, and said it was extremely comfortable after sleeping on it for 5 days.2: Getting the 6 inch is 1 inch too big for most sleeper sofas. When you fold it up the first fold is a little tight, but again, it's foam so it WILL fold. Just takes a tad more pushing to get it into that first "lock" position where the leg bar pushed down. After that, the second part that fills into the sofa is a breeze just like always.3: Since it's bigger, that means you get a tad bit of bulging in sofa mode. My experience with owning 2 sofa sleepers is, that ends up being a more comfortable sofa (especially for this one) as well as a more comfortable bed.Bottom line is, I'm extremely happy with this and am now even thinking about upgrading our regular bed to this kind of mattress. But it made both the bed and the sofa better and that's simply astounding for a really cheap sofa sleeper.
