ZINUS 12 Inch Support Plus Pocket Spring Hybrid Mattress, Full, Strong Coils for Durable Support, Pocket Innersprings for Motion Isolation, Mattress in A Box

Short version: My wife and I have had this mattress for over a year now and can say with confidence that it was an excellent purchase- it is still firm and has no sags or dips. I highly recommend it.I have held off on writing a review for this mattress because I felt it was necessary to sleep on it for an extended period of time to give it the most fair and accurate review. My wife and I purchased this mattress over a year ago, in November 2017.After going to all the local stores, from big box to mom and pop, my wife and I found ourselves with a problem: we could tell which mattresses were soft and which were firm, but aside from that we didn't really feel much difference apart from the price tag- almost all of which exceeded a thousand dollars, with some approaching two grand. That's quite an outlay of cash.So, going off reviews on Amazon we took the leap on this Zinus Extra Firm iCoil 12 inch king mattress. We also purchased a steel foundation upon which to set the mattress in our bed frame. The box arrived a little beat up, but my wife and I muscled it into the house and carried it upstairs together. It's a two person job, but not impossible. We set the rolled up mattress on our guest bed and carefully cut away the plastic so the bed would unroll. (Pro tip: Don't stand between the mattress and the wall. You might get pinched) We followed the directions and let the mattress sit undisturbed for 2 or 3 days so it could fully expand. After which time, we moved it into our bedroom.It's now more than one year on and I feel qualified to report on the mattress. It is firm, but not rock hard. This is obviously subjective, so all I can say is that you know a firm mattress when you lay on one, and this is a firm mattress but is still comfortable. I'm a side and stomach sleeper, and my wife is a back sleeper. I'm 5'11", 230lbs, and we'll just say that my wife is plus sized and leave it at that. The mattress supports both of us fine, and a year later has no depressions, dips, sags or problem areas. The last time I did laundry I snapped some photos of the mattress which I have posted above. You'll notice the mattress is still even and flat, even after a year of nightly use.I purchased this mattress myself, with my own money, have no relationship with the manufacturer, and am receiving nothing in return for writing this review. I just know how difficult it is take the leap of purchasing something like this over the internet, so I thought I'd write a review to help people in a similar situation my wife and I found ourselves in last year.This mattress was an excellent purchase, I've recommended it to friends, and if you're in the market for a fairly priced firm mattress, I can recommend it to you as well. Cheers.

Didn't want to review this too soon so now some months have gone by and I am. I am 6'6" and weighed over 300lbs. I like firm beds. Not crazy sleeping on cement beds but ones that don't move around but have a little and I mean little cushion on top. I can't have these pillow top crap things that are SO SOFT. IT MUST BE FIRM>>>FIRM FIRM... I had a bet years ago and I don't remember who made it and I search and searched but I don't know who made it. Today, I was looking at BLACK by beautyrest but I can't see spending 3k for a mattress or more. Even then their firmest was not as firm as I like. What drew me to this bed was it said BIG AND TALL... which is me... and then extra firm. Extra firm, heavy duty... these are my kind of words. I thought I would try it. YES it is really heavy in the box and out, once it is out so be sure to have your frame set up with it ready to go.I am not sure how many months I have owned it now but I can tell you this. It wasn't long after I bought the first one that I bought a second one. That was my immediate pleasure with these. FIRM.... yes it is... a little indenting when laying on it... yes but it is FIRM. My OLD firm mattress I actually had to put a topper on it for it was so firm. This one doesn't need that. JUST RIGHT>I have no back pain and my Eastern King is big and perfect. Can I believe it was 400 dollars. NO WAY... Not at all. Since I have had it I have been paranoid about it grooving or slotting to where I always lay... so I have rotated the bed every few weeks. There is no indent and I would say at 320lbs. that can have a pretty possible outcome with that. Nothing. Fine. I do rotate it though. It is still firm. NO REGRETS. I just can't tell you for the price and even throwing away the price this is a great mattress. I would compare to beautyrest black... forget their silly fancy name... their firmest one.I have two of these kings. They are fun for my daughter to run and dive on. They are soft enough so your neck doesn't hurt but do not get me wrong. They are firm in a a great way. Go and sleep on the black BR beds on their firmest ones for 4k or more... then buy this one... with 4500 extra bucks in your pocket I am SURE you will be quite happy with these mattresses. I am and I MUST HAVE A FIRM BED. Must. No sitting on the edge and it sags.... or sinks in and didn't have a firm bed sleep... then my back is killing me. It is a good mattress regardless of the price. I will NEVER EVER pay high dollar for a firm mattress again.Now, the bad side of this... it is HEAVY. If you have to move it from room to room and you are small... good luck it will be a chore. If you are big like me... it will still be an effort. So my advice is to KNOW what room you want it in... unbox it and unwrap it there and be done with it with no plans on moving it again. Best suggestion... set it and forget it :-) I also bought the frame that came with it. Good combo but the real star is the bed.Will always buy these beds... 400 bucks... give me a break... and firm like a high end mattress... Totally happy. By far the firmest with perfect amount of comfort and for this price is silly. You will see that it is comfortable and firm. Firm, no spunge thing.

This mattress is value for money. I was nervous opening it as I have never bought a mattress in a box. I was also worried that it contained CFCs or would off-gas and maybe contain something toxic; but the mattress expanded fully without any issues and I have been using it for about a month. Nice and firm and I sleep right through the night with it; which is why i bought it! The closest comparable mattress is sold by The Brick in Canada, for about $575 including a box spring; or a $299 new mattress and $165 box spring from Salvation Army. Though i didn't want to give Jeff Bezos yet more money, as he has already collected (I would not say earned) more than $78 billion dollars extra during the plandemic, nor the CCP (yes, like everything else the mattress is made in China) I felt there was little option based on value for money.

The bed came earlier than promised. Setting it up was easy for the 2 of us. Took proper shape almost immediately but we let it expand for 1 night before sleeping on it. No odour at all. The price was really good, and so far it is exactly what it claims to be. I've only slept on it for a couple of weeks, and it is very firm, which my husband loves but I am still getting used to. There are no lumps or bumps or uneven places, and the edges are firm, which was important to me - I sleep on my side, usually with an arm hanging over the side of the bed. I didn't want a mattress that I would roll off of lol. I only gave 4 stars because we've only had it for a couple of weeks. I will update when I can give a more relevant review after a few months. But so far, I would recommend this mattress.

I bought one of Zinus’ memory foam mattresses two years ago and was looking for something firmer for my mom. Ordered this mattress in twin size through prime and received it within 2 days. It’s a spring mattress vacuum sealed in the box. I would say this is an extra firm mattress. Photos included are of the mattress within 5 minutes of unwrapping from the box. Beware it expands quite rapidly - within 5 minutes it was already at 10 inches and at 30 minutes at 11inches in height. Will be letting this expand for a while but lying on the bed so far I have zero issues. Was very hesitant because some reviews said the mattress wasn’t firm enough but trust me, it is. For $200 it is well worth the money.

WE TRIED SENDING BACK AND MISSED IT BY 1 WEEK ! TERRIBLE NOT SUPPORTIVE AT ALL

It got delivered before time. The packing was a little beat up, but I could not find any damage on the mattress which is good. Although it's extra firm, I could use a little more firmness transitioning from a firm foam mattress. But all in all no regrets so far. I like the quality and build so far.
