Received this mattress over 2 weeks ago, it is still setting off the fire alarm in our house. We have the window open and 2 fans going and everytime we turn the alarms on it goes off within an hour.  This is unnerving and worrisome to know the mattress has soooo many chemicals in it.  Gives us headaches just to breathe it for any short period of time.  The mattress itself feels amazing, but the off gassing is a problem might have to return it:(<a data-hook="product-link-linked" class="a-link-normal" href="/Zinus-Memory-Foam-12-Inch-Green-Tea-Mattress-Queen/dp/B00Q7EPSHI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Zinus Memory Foam 12 Inch Green Tea Mattress, Queen</a>

Comfort wise I love this mattress. I have had it for 2 months now. I purchased it for my son because his mattress was to soft. He loves it. I would consider buying one for myself to replace my $2700 King size mattress which was hugely disappointing. The only negative is the smell. I was hoping it would completely dissipate with time. But it still smells, although not as badly as it did when I opened it up. To much hassle to send it back plus it would cost a fortune I'm sure. From the reviews not all of them smell badly, I guess I got  one that did.

I wish I could give this 3.5 stars. But because I only have 1 issue with the product I guess I will round to 4.

This mattress falls between medium soft in my opinion, I was nervous that it would be hard. I will say that it takes a bit for your body and the memory foam to mesh. Once you start to lay down then you feel the foam confirm to you body, but at first impression and feeling it with your hand it does feel hard. But give it some time to break in, and give it sometime for the memory foam to adjust to your body.

The smell that a lot of people have complained about in the reviews was very mild, and not really noticeable at all. So I'm not sure what those people were talking about.

HOWEVER, the one thing that is disappointing is for the first 1-2 weeks I slept on it, I noticed everyday I was waking up hot, and even sometimes in a pool of sweat. I thought I had too many blankets on but it in fact was the mattress. You can literally feel heat underneath you in the area you're sleeping in.  It seems to trap a lot of heat, even though it claims to have gel in the mattress for air circulation. 1 inch of gel seems to not be enough, or just  isn't working well enough. I've also have not good a good-DEEP sleep in this bed yet. I'm always hot when I wake up if not, sweaty. I'm actually now searching for cooling mattress pads, it sucks I have to spend money again but It's fixable.

Besides the overheating/trapping of heat. It's a pretty good mattress for the price.

We took a chance on buying a mattress online and it has turned out well for the most part. Now that we have had it for a couple weeks a review is in order. We love the way this new mattress feels. It shipped on time and has NO Chemical odor. Big plus for this type mattress. The price is great too. The materials and overall workmanship are very good. The bamboo cover and wool layer make this a very comfortable sleeper.
**I do have one complaint: The edges and corners are "soft" and do not fully "inflate" to the same firmness as the rest of the mattress. You wind up with less usable area than the listed size. You have to sleep closer to the center of the mattress than on other type mattresses. The head, foot and sides all droop a bit and that is taking some getting used to. You feel as if your head is a little low and as if you might roll off the side (and I almost have twice).
If you have the option, go up a size from what you are currently using.
All in all - it's a very good product, but it would be a GREAT product if the edges were the same as the center.

The mattress is rated as a firm plush (meaning soft top coat over a firm mattress). However, I can sit on it and sink through the mattress and can feel the bed under my butt (generally, I don't sit on my bed, but I never had this "sag through" effect with my prior firm mattresses). When laying on it, my butt sags into the mattress noticeably feeling somewhat out of alignment and I'm waking up with a rather stiff neck after several weeks (should be enough time for my body to "adjust" to the new mattress). I'm somewhat disappointed as I was anticipating a solid feeling mattress with a cushy top coating on it, which just didn't turn out to be the case.

This is the most comfortable mattress I've slept on in years, however, I'm not blown away by the value.  I'm coming from a few furnished apartments in Australia, and and a nice "Extended Stay" hotel before this.  Before that, I was using a similarly priced 7" latex composite mattress from the Swedish big box furniture store.  THAT was the most comfortable mattress I can remember.

I'm 180 pounds with an athletic build, and a side sleeper.  I find that this mattress has the comfortable medium-firm top that I prefer, and plenty of give to avoid pressure points.  I'm a hot sleeper, and so far it seems pleasantly cool.  What holds me back from loving this mattress is how the bottom layer of foam seems to crush down twards the edges, or when it's pressed on firmly.  It feels like a low-density foam lower layer collapsing away from the pressure on the upper layer more easily than it should.  I don't recall this distinct two-layer sensation with the prior latex-hybrid mattress I owned.  That mattress felt supportive and solid, without the perceptible transition between compressing the latex, then squashier polyurethane layers; in spite of it's similar, though slightly thinner construction.

I bought this mattress expecting to use it for the next two years I'm in my current city, but I question the manufacturer claim of 25 year longevity.  This mattress is a solid choice for the price, and I'm happy with the purchase, but I was hoping for a bit more "solid" a feel.

This is a very comfy mattress for the price. It is on the firm side. The one drawback I noticed is that the sides are not reinforced, so when you sit on the edges, they go down quite a bit. This mattress is also a bit shorter  in length than our other queen mattress. This no problem for my husband and me, but could be a problem for some folks. All in all I'm pleased and sleeping great, but if I had it to do over again, I'd get one of the mattresses from this line with a couple of inches of memory foam on top.

Note: After sleeping on this a week, I decided it was too firm for me. I love it when lying on my back, but I just can't sleep that way. Sleeping on this on my side, there is not enough padding for me and my shoulder starts hurting. This underscores my above comment about getting a mattress with a couple of inches of foam on top.

I want to start by saying I LOVE this mattress. But the odor is awful. I cant even describe it. No amount of febreeze or letting it air is touching it. Its awful. Anytime you lay down its like you just unwrapped it all over again. Im not sure what to do.

Other than the awful smell, I love it. Its very comfortable. Not too firm and not too soft.

This is a fantastic mattress.  First, in the queen size, the box is large and heavy.  It's 5'3" tall and weighs a bit over 90 pounds.  This is not a deal killer by any means, just be prepared.

Once we got it in place, we unpacked it and unrolled it.  For those that have not owned a memory foam mattress before, this is probably 4 inches thick when initially unrolled.  No you did not get ripped off.  Just unpack it and unroll it and give it some time.  I believe they recommend 24-48 hours, but almost immediately you can see it expending.

The gel part of the mattress seems to have caused some confusion.  This is not a liquid gel.  It will not "pop" or leak.  It's a gel that is infused in the memory foam.  It offers support and keeps the memory foam from getting super warm (which was a significant compliant when memory foam mattresses first emerged).

A mattress is a uniquely personal choice.  That said, this is a very comfortable mattress.  It's supportive, but not rock solid.  It just seems to cradle you.  I am a big guy, well over 280, and found this to be supportive all night.

I never got hot, nor did we have a huge odor issue.  Yes, when you first open this, there will be some odor.  It dissipates in a few hours, but people very sensitive may be initially bothered.

This is a great buy, you will love it!

I waited 90 hours to put linens on the mattress to give it plenty of time to air out, however this was not enough time to get rid of the odor. After two weeks the odor was still strong, so I put a mattress incasement on. There is still some odor that comes through. I may return it for this reason. Regarding comfort, at first I had the mattress on a box spring and it was very soft and didn't lend much support. I ordered a Zinus frame and it totally changed the feel. It now is quite firm, although the memory foam confiorms to the body. It is quite comfortable.

We bought this mattress last fall. I purposely waited several months before writing a review. WE LOVE THIS MATTRESS!!!! We stayed at an airbnb last October and they had this mattress. My husband and I stripped the bedding, got on our hands and knees AND flipped the mattress just to find the brand name. The only downside is the chemical smell. The first night sleeping on it I woke up with a headache. The next several nights I slept in the spare bedroom. Meanwhile, I opened all the windows, turned on the ceiling fan, placed bowls of baking soda around the bedroom, etc. Nothing wrong. We just so happen to buy a mattress protector and that did the trick. I've slept in my bed every night since.

I love this mattress topper. I basically like to pretend I sleep on clouds (we have a pillow top mattress plus this 4 inch topper). It's very comfortable, and you can sleep for what feels like days on it. My only issue is that if you (or two people) sleep in the middle of the bed, it bows up on the sides so you feel stuck in the middle of the bed and have to wiggle your way to the side of the bed at times. I had to get a deep mattress pad in order to try to combat this, and it's helped but still seems to be a bit of a problem. That's the only reason I took off a star... Ultimately, I love this topper.

My initial impression of this mattress is actually quite positive.  I'll cover the transaction from as many aspects as possible to include: specific application, shipping time, quality of shipping materials, unpacking the mattress, residual production odor, relative firmness of the mattress and the most subjective impression of comfort.

- The mattress is a twin-sized mattress I purchased for my son's bunk-style bed.  I was forced to choose the 8" mattress due to safety considerations relative to the design of the top bunk bed (there is actually only one bed in the set - the lower area is an under-dresser).  I would have preferred a thicker section of memory foam and less base foam in this mattress thickness design.  The negative critique I have for this particular mattress is that it was as expensive as the 10" mattress with a 2.5" section of memory foam, which comes off as the company maximizing the profit margin on the bunk bed market.

- Shipping time was within the posted shipping window.  It took about a week to get to the Pensacola area.

- Shipping materials were very good.  This is an area where many retailers cut corners.  This vendor did not - the box was a heavy duty tri-wall box, and the mattress was wrapped and rolled in heavy gauge plastic wrap.

- Unpacking the mattress was very straight forward and took less than 5 minutes.  the mattress is essentially placed in a bag and either compressed or vacuumed flat, and then rolled.  The mattress reached full thickness in about 4 hours.

- I had concerns about residual odors due to the fact I have chemical sensitivities and allergies.  This was one of the main reasons I chose the Brentwood - due to the fact it was manufactured in the U.S.A. and made of CertiPur foam.  The bottom line is there was no noticeable chemical smell, residual fumes or any offending odors from the mattress.  I only noticed a very slight odor the moment the mattress came out of the packaging bag, but that immediately dissipated and there was no lingering smell at all.  The mattress has been unpacked for several days and still no odors - meaning I didn't have to do the vinegar water ritual to purge the chemical demons from the mattress.

- This mattress is on the softer side for an adult, but appropriately firm for a small to medium sized child.  In other words - the more concentrated your mass, the more you will sink into this mattress.  Therefore, this mattress will be relatively firm for a child.  I slept on the mattress for a couple hours and did not find it as firm as I prefer - but it was still relatively comfortable.  My son seems quite content with the comfort level and sleeps much better on this bed than he did on his toddler bed.  He would constantly toss and turn on his old bed, but seems to stay in place with this mattress.  I would estimate the memory foam used in this mattress is medium density.  A note that contradicts a comment by one of the other reviewers - there was no need to use a box spring with this mattress in my application.  The mattress I purchased is sitting on slats, and even with my 165 lbs laying on this mattress - the mattress evens out perfectly and you can't tell it's on slats.  I can see the need for a platform if your mattress does not sit properly on an open floor-mounted bed frame.  However, you can save a lot of money by just cutting some quality 2/3" plywood to provide a squared base - unless you want the bed to sit higher.

- Overall, I think this mattress is a good value for the price.  The 8" mattress is comfortable, there was essentially no residual odor, it's made in the U.S.A. and the shipping was timely and free.

The downgrade to 4-stars was due to two factors:  1) the 8" mattress was the same price as the 10" mattress - even with less material (most notably the 1/2" reduction in memory foam thickness - memory foam being the most expensive component of the mattress); 2) the memory foam is medium to low density, resulting in a relatively soft mattress for most individuals over 150lbs (the mattress is softer the more concentrated your mass is).

Beware the smell, other than that, it is an amazing thing to buy a mattress for that price. Very comfortable.

Im happy with the mattress itself. It came in a box as described and inflated fully and evenly. The firmness is just right for my back. The one thing I still have to adjust to is the strong chemical smell, it still gives me headaches. Its slowly wearing off.
 Im giving it 2 stars for how the shipping was handled. I received the package wayyy past the estimated shipping date. Although there was a delay from the carrier, I wish I had been updated during the process. I didn't get any updates regarding the package itself for 10 days as to where it was or if I would still get it. Unfortunately, I had gotten rid of my old bed thinking the mattress would arrive on time. I just wish I had the option to cancel the order and reorder another one.
Be prepared for delays in shipping as well as the strong smell.

I opened the box and put the mattress in my guest room.  I let it rise and air for 3 days before I tried sleeping on it.  It is very comfortable but there is some of that memory foam quicksand feeling to the mattress.  I did not notice any chemical odor after the 3 days (I left the ceiling fan on and the window open a few inches while it expanded.  I like the cool gel and ventilation.  I did not get overheated sleeping on the mattress as I do on some of the memory foam mattresses.  All in all it is a good mattress.  Very comfortable and fits over my box spring.

The good- this mattress is SO comfortable. Im a stomach sleeper and it isn't too soft but not too firm either. It was easy to unpackaged even all by myself. The total weight was about 70 pounds. The price is unbeatable!

The bad- as seen in other reviews, the 12 inches did not fully expand. Youll get about 10 max. I don't know why, possibly because of what it is made out of but this mattress absolutely wreaks. It has sort of a toxic/chemical/burnt smell to it. Not sure how long its supposed to last.

Ill update in about a month so see how its holding up.
