Exactly as advertised, love it!
Summary: It puffed up evenly to a full 12” in less than 24 hours, I slept on it the first night and it’s firm.Ordered it Friday, arrived Sunday. My husband helped me carry the box inside and upstairs then I handled the rest.By the time I finished opening the plastic down the second side, it was 11” puffed up all the way around. (Picture shown.)I’m not patient and don’t trust my pups or cat so I put a mattress encasement on it immediately. Kitty had already slightly snagged the mattress cover when I ran downstairs to get the cover (Picture shown of encasement on.) Then I added the fitted sheet. I figured if it stayed at 11” then I’d be ok with that but I needed to cover it so it didn’t get ruined by my pets. It was worth the gamble of not fully getting to 12”.We all laid on it during the day then I slept on it with one dog and cat that same night. Today (24 hours after unboxing) I measured again and it’s a very full 12”.It’s firm. I haven’t really compared others but I did sleep on one that I would consider extra firm. This is definitely firm or medium firm.A couple observations: it was not as firm after opening and I was worried it wasn’t firm enough for me. Also, the edges weren’t very supportive immediately after opening so I was worried I wouldn’t be able to sleep to the edge if needed but as I sit here and type this, I sit on the very edge of the mattress, feet on floor, and notice that I only sink down 3-4”. For reference, I’m about 155lbs. It’s much more firm today, 24 hours after unboxing. So give it time before you fully judge.I definitely received the advertised product. People who mention issues may have a defective product? I plan on buying the identical 12” King size mattress for our guest room because this is exactly what I was in the market for and it lived up to what was advertised and exceeded my expectations!Definitely one of my top 3 purchases this year! (First being the floor vent register booster fan for my bedroom.)

I just moved into an RV and was looking for a mattress for the platform in the bedroom but it’s a special size so there weren’t a ton of options so I very carefully read reviews, looked at stars of different things, and read the description. Despite slim pickings’, I still needed a firmer mattress due to a severe back injury I’ve had and in the very description it speaks of being pain relieving, to which I was a bit skeptical but everything else looked really good so I went ahead and took a chance on it. Boy am I glad I did! It only took about 2 days to decompress fully from the box. It’s quite firm yet soft enough to sink in just a little, like the perfect amount. Now let me touch on this cooling effect and pain relieving factors. WOW! I mean WOW! I have been sleeping beautifully for days now, sleeping without waking up in the middle of the night due to back pain from laying down that long and I normally wake up for the day in a world of pain and have to take my pain meds before I can even sit up and stand up (successfully). I have not woken up with an ounce of pain, I wake up refreshed and ready for the day. This morning I didn’t even have to start the schedule of my 4 times a day medication upon opening my eyes during normal life with my normal what I thought was a great bed, a Serta. The cooling feature is just as wonderful. It feels great, I haven’t gotten the least bit warm as I usually do. So the description of the mattress is spot on, believe every word of it and what a bargain price for all of that!! When it comes time to replace it in my stationary, lived in full time RV, I will never get any other mattress. This mattress literally has everything I’ve ever wanted in a mattress and for such a great price at that. Needless to say, there are no cons whatsoever.

Size: QueenStyle: 8"Pattern Name: Original BoxVerified Purchase
I purchased the Zinus 8 Inch Gel-Infused Green Tea Memory Foam Mattress / Cooling Gel Foam / Pressure Relieving / CertiPUR-US Certified / Bed-in-a-Box, Queen size. It has three different layers of foam and is not a hybrid model. First is the 4.5" high-density base support foam, next is the 1.5" comfort foam, and on top is the 2" gel-infused memory foam. This is the first foam mattress I've ever owned, and I'll never go back to using the old box spring mattresses I've had all my life. The first night I slept on it with only a single sheet covering over the mattress and I was stunned by how nice and comfortable it feels compared to everything I've ever slept on before. The second day I installed the SafeRest Queen Size Premium Hypoallergenic Waterproof Mattress Protector, which is quite thin as it's a mattress protector and not a mattress "pad." I noticed no difference in how it feels in any way with this addition after using the bed all day and sleeping for 8 hours the second night. I believe it's so comfortable because of how your body sinks down into the foam slightly which supports your mass more uniformly than other surfaces can. Don't get me wrong about this, it's still a quite firm mattress so it's not like you sink way down into it. I wish there was some way I could better express just how much I love my new Zinus mattress!!! This is like sleeping on a cloud!
I've read some negative reviews about people who've removed the cover that comes on the mattress to wash it or for whatever reason and then went nuts complaining about loose fiberglass fragments they encountered afterward. I believe the tiny amount of fiberglass material built into the cover is part of the fire-retardant material that makes up the cover. I also believe the warning the manufacturer gives about not removing the cover is their way of being over-cautious about the possibility of customers coming into contact with fiberglass fibers if they do so, and anyone who has removed the cover has NO ONE TO BLAME BUT THEMSELVES for any problems they encounter for failing to follow the manufacturers instructions. I haven't removed the cover on mine but I did open the zipper about 12" so that I could stick my bare forearm inside and rub it around to see for myself if there really was loose fiberglass fiber but I didn't notice any indication of this at all. My recommendation if you ever feel the need to remove the cover to wash it or whatever is remove the cover, deflate the air out of it and then CLOSE the zipper (without turning it inside out) and then arrange it around the center post of your washing machine. This will ensure the inside and outside of the cover won't come into contact with each other. Wash on a delicate setting, no bleach, then after removing it from the washing machine don't put it in the dryer, just lay it out on the floor to dry before putting it back on.
The first picture was taken just 5 minutes after removing the mattress from the box and it's a full 7". 36 hours later it had expanded to the full 8" as can be seen in the second picture. After about 36 hours it was fully expanded and was very smooth and flat with square edges, and it looks almost perfect in every way. I have no idea how long this mattress might last, but after paying only $200 plus $18 in sales tax with free shipping it's easy and cheap enough to replace. I'm still using my old bottom box frame but since the distance between the support slats is a full 6" on my old base, I show in the third picture how I installed (with a few screws) some pieces of 1/4" plywood to the top of it for better support for the foam mattress. I simply bought and installed 3 pieces of 1/4" plywood at 24" x 48". I needed to cut the width of one piece for the foot end of the bed down 4" so that the plywood would break over the supports slat of the old box base. If you choose to follow my example you may need to modify this to some extent depending on the spacing of the support slats of your base.

Comfortable, cool, supportive, totally worth it
Reviewed in the United States on April 5, 2024
Had ordered the queen, in a "new small box". Packaging was excellent. Allowed around 30 hours for the mattress to expand. But it never expanded to the full 12 inches, it was about 0.5 inches short (and remains so, to this day, i.e. after a month) and that is reason for the 4 stars. That being said, we have no other complaints- we have had quality sleep, feel well-rested on waking up. The mattress does provide adequate support (which was a bit of a surprise, since we were accustomed to a spring mattress and I was skeptical about this one, since it is a foam mattress). It is cool and soothing. I believe we made a very good choice.

I got the 12 inch king size and it’s so comfortable. Definitely be patient with it fully firming up/rising. Took about 5 days for the mattress to fully extend and firm up to what it’s supposed to be. It was very soft the first few nights but is a medium feel now. Great deal for the price and very comfy!

Unpack:
I was able to unpack it and place it on my bedframe by myself and it wasn't too bad at all (I'm 5'2). I do recommend getting help if you have stairs. Pretty heavy and awkward, especially if you're a shorter person.
Decompression:
This is what I was mostly worried about. I kept reading that a lot of people were having issues with this mattress reaching its true size; however, I found that it was almost at its true size within the first 24 hours. I still have another 48 hours to go and about an inch of decompression left.
Chemical scent:
I also kept reading a ton of complaints about the chemical scent. I found it dissipated within a few hours. Especially after I put on the mattress protector and my bedding.
Firmness:
I read that some buyers were disappointed at how soft or how firm this mattress is. As a side sleeper, I can't have a super firm bed, but I also feel uncomfortable with a super soft bed, as I sometimes combination sleep. I found this sank moderately at the right spots. I dont feel pressure points, but this is memory foam and that is the best for side sleepers (that's what my research tells me, anyhow). It also helps big dog joints (for those who sleep with their pups). I have a 122lbs Italian Mastiff, and she loves our new bed. My big girl falls asleep so quickly and sleeps all through the night without getting up to adjust herself. Still need more time to see if it continues.
Value:
My last mattress was over $2000. After buying this one at about $460-ish, I cannot believe I spent so much money on my last mattress. I guess I still need more time to form my final opinion, but for now, my gosh! Do I ever feel lucky to have come across this mattress.
What type of sleepers should buy this:
I highly recommend this mattress for side sleepers, as we typically need pressure relief for hips, knees and shoulders. This mattress sinks slightly in those places providing relief that is hard to find outside of the memory foam mattress spectrum.
Combination or stomach sleepers may need something a bit more firm.
1 year update:
It's been nearly one year since I bought this mattress and my pup and I are still in love with it.
It hasn't changed since my last review, except that it eventually reached its full decompression size of 12 inches within the first 72 hours. No chemical scent. Best sleep of my life.
I will never go back to buying mattresses from a department store.
2 year update:
My big girl and I are still loving our mattress. It hasn't sunk in where we both sleep and it continues to be an amazing restful experience for the two of us.
Now, when I sleep anywhere that isn't my mattress, I can feel the difference in quality and I miss my mattress lol.
I will continue to stress that this is ideal for side sleepers. Combination and back sleepers may need something firmer, whilst stomach sleepers may require a softer mattress.
If you're a side sleeper, give it a go! I don't regret this purchase one bit.
