ZINUS 12 Inch Green Tea Cooling Gel Memory Foam Mattress, Queen, Fiberglass Free, Cooling Gel Foam, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, White

Let me start off by saying that it has been a rollercoaster ride with this mattress. Okay, so why the 5 stars, you ask? Well, I will tell you why.When it arrived, everything was great. It was packaged well. Vacuumed sealed so tight I didn't think it would ever unroll right. I gave it the full 72 hours to inflate. That's when the problems occurred.At 75 hours, the mattress had barely inflated to 8 inches. For reference, I bought the 10-inch. And I know sometimes that the measurements can be a bit off, so I considered it my fault for being such a cheap arse and not forking out for the 12 or 14. My reasoning: I was gonna get a topper at some point and I don't want to be like Princess and tf-ng Pea in a room with a low ceiling.I waited another day. Measured again. No sign of movement. I tried to contact the seller and, well anyone who has tried doing anything on Amazon knows how wonderful that is. Instead of giving me the seller, it sent me ring around the rosy with processing a return. I cannot tell you how many times I made it clear that I did NOT want to send it back and I did NOT want a refund. I only wanted help in trying to resolve this issue myself. I felt it was something that could be fixed. If it came to it, then we could talk about credits or refunds.This went on for over an hour. I finally managed somehow to be taken to the manufacturer's website and, once again went through the drama of "No, I don't want to return it and I don't want a refund. I just want help." I finally reached a human being at some point. A person by the name of Maverick contacted me and suggested I set the mattress on the floor and roll around or walk on it a bit. Apparently, sometimes the memory foam doesn't want to decompress all the way. These actions tend to help.I wrote back to him every time there was movement. 9 inches. 9.5 inches. I was so excited the day after my roommate slept on it that it got all the way up to 10 inches inflated! I immediately fired off a note to Maverick to let him know and to thank him for the suggestions.He was patient and told me exactly what needed to be done and why. It never even occurred to me that sometimes memory foam just "be that way" and you have to sort of give it a boost.All that said, I've been sleeping on it now for about a month. It's probably the most firm memory foam I've ever owned, and I probably could have done well with one a bit squishier, but this is fine. I got exactly what I ordered. I'm not gonna complain about that.I don't see any evidence of fiberglass, as mentioned in another review. Of course, I don't ever intent to remove the protective cover and will instead have one on top of it at some point.It being several inches more shallow than other mattresses I've owned, let me just tell you know... it puts them to shame! My previous mattress, same brand, was a 12-inch and not nearly as firm. It had edge issues where you'd fall to the floor if you weren't careful. I don't see that being an issue with this one. It's fairly sturdy sitting on the edge and I imagine that if I had access to the corners they would be the same #sleighbed. And my previous mattress, you could feel the metal slats underneath every freaking time you turned. It was awful. I had to put sheets of plywood down to keep from being gored in the night. With this mattress though?? I don't feel a dang thing. Granted the slats on this bed are wooden and not metal, even when I pounce on the bed, I don't feel a thing - just snuggliness.I'm waiting for my bed to break if I do that again though - for reference, I'm about 345lbs. Do you have any idea what that does to a bed if you just pounce on it like a lion on the Serengeti? Apparently, nothing (knock on wood). The mattress absorbs the impact. I would be confident with dropping an egg from a skyscraper onto this mattress. That is how awesome it is.It didn't have any sort of weird odor when I removed it from its wrapping. The only thing that sort of made it difficult to get any help was that the date of manufacture was missing from the tag when I was trying to get assistance from the manufacturer. If anyone has to deal with that, just take a picture of the tag anyway to prove that it is blank. It'll help you out in the long run.If I'm ever in the market for a mattress again any time soon, I am definitely purchasing this one - as long as it's available. I can sleep at night. It doesn't aggravate my low back pain or even my hip pain. I'm actually grateful it isn't as squishy as I would like because then my problem would be never wanting to get out of bed. Heck, even with my weight (when lying down) I barely sink into the mattress. And at least now I can wake up in the morning and go about my day without feeling as though my body has been hit by a truck and all I want to do is stay in bed. Very happy with this purchase!

I just purchased this Zinus mattress in an 8" twin for my granddaughter because I am so happy with my 12" Queen. I checked to see when I purchased mine and it was June 1, 2021, so it is 4 years old. I am so happy with this mattress that I still look forward to crawling into my bed at night.Prior to this purchase, I had a very nice pillow top that was super comfy but I woke up with my back hurting probably because I am a stomach and side sleeper. My daughter told me how happy that she was with her Zinus and had also purchased a twin for both of her kids and everyone was happy.It only took 24 hours to get to full capacity and the smell dissipated quickly. I do turn it every couple months since I was in the habit from my previous bed although you can't tell the difference. The mattress is exactly the same as when I first purchased it.I recommend this mattress and for the price, warranty, and for comfort, you can't beat it. My bf has a memory foam mattress that he paid 3K for (insane) and it doesn't feel any feel any different than my Zinus.There is a reason why there are so many 5 star reviews - don't hesitate if you are in the market for a great mattress.

In 8 years, my husband and I purchased five mattresses!! Three were very expensive, one was more mid-range and this one was unbelievably inexpensive. We have had it for six months now and we are both in love with it. I've liked it from day one, but it did take me a bit of time to get to the love part. I think all mattresses take a little getting used to, but now, every night when I crawl into bed, I think of how much I love this mattress! This is the first mattress we've had in years, that doesn't give me low back pain, and it's easy on all the other joints too and we are in our 70's! There was a very faint smell when we first unwrapped it, but it dissipated in a couple of hours. I'm super sensitive to smells, so I know there weren't any odors by the time we went to bed. I also can't sleep on a mattress that traps in the heat so the Green Tea Cooling was an important feature for me. I have never had an issue with it being hot at all but I will add that I make sure all the sheets, blankets and comforters we use on our bed are 100% cotton. (I have found that all synthetic fabrics will retain heat). When you take into account the comfort of this mattress and the price, I believe it is the best mattress deal I've ever come across! I highly recommend it. I found this mattress when I spent several nights at a Hotel in Boulder City, Nevada. I loved it so much that I hounded the Front Desk staff relentlessly until they got me the information I needed to order one. It's definitely one of the best purchases we ever made!
