10 Inch Green Tea Cooling Memory Foam Mattress [New Version], Full, Fiberglass Free, Medium Firmness, Cooling Gel Foam, Certified Safe Foams & Fabric, Mattress in A Box

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!

The Zinus 12-Inch Green Tea Cooling Memory Foam Mattress (New Version) is an outstanding choice for eco-conscious sleepers who prioritize cooling technology and safety. While marketed as "Medium Firmness," user feedback consistently highlights that this "New Version" leans significantly toward the very firm side of the spectrum. Key Features and Performance Cooling Gel Integration: The top layer features cooling gel-infused memory foam, which is "super effective" at regulating body temperature and preventing the "sleeping hot" issue common with traditional memory foam. Fiberglass-Free Construction: A major highlight of the "New Version" is the fiberglass-free inner cover. It uses a safer fire retardant, providing peace of mind for those worried about skin irritation or indoor air quality. Certified Safe: The foams are CertiPUR-US certified, ensuring they are made without harmful chemicals, and the fabric is OEKO-TEX certified to be free from harmful substances. Mattress in a Box: The convenience of shipping is high; it arrives compressed and expands quickly, though it is recommended to let it air out for 48–72 hours for full expansion and scent dissipation. The "Firmness" Factor Despite the "Medium Firm" label, this mattress provides high-level support that may feel rigid to side sleepers or those who prefer a "sinking" cloud-like feel. Best for: Back and stomach sleepers who need spinal alignment and a solid surface. The Challenge: If you are a side sleeper, you may find the lack of "give" around your shoulders and hips uncomfortable without an additional topper. Final Verdict If you are looking for a durable, safe, and cool mattress that offers heavy-duty support, this Zinus model is a top-tier budget pick. However, be prepared—this is a very firm mattress that prioritizes support over plushness.

TLDR: Great mattress considering its thickness. Good support. Adequate combination of firmness and softness. I had a very good experience with another 14 inch mattress from Zinus before (I had to give it up because of moving), so when I needed a thinner guest mattress I thought I should give this one a try. I have been sleeping on it every night for the past 2 weeks and I haven't had any back pain issues so far. It is firmer than my old 14 inch Zinus mattress. Nevertheless, it still does a good job considering it is much thinner and has no springs. The memory foam is comfy and helps with my comfort as I'm a side sleeper. It inflated within a couple of hours, but I let it rest for 48 hours just to be on the safe side. It was in its full thickness after 12 hours though ( I didn't notice any visible change after that). It didn't have any bad/plastic smell either. Pros: * Right balance of firmness and comfort * Fits under my queen bed easily * Detachable and washable cover Cons: * Slightly firmer than what I like, but it is not a deal breaker Verdict: If you have space under one of your beds and want to host a guest, do not hesitate to get this mattress. They'll love it!

Paquete entregado un día antes, genial. Por otro lado, el colchón muy cómodo. La verdad que mejor de lo que esperaba. Excelente artículo y el precio accesible. Lo volería a comprar sin duda alguna.

I’ve actually purchased this mattress twice, one twin and one double, mainly for our kids, and overall I’ve been happy with both. We’ve had the twin for a few years now, and it has definitely softened over time. That said, it’s still holding up and doing its job, especially for everyday use. One thing I did notice is that it was quite supportive at the beginning, and it actually helped with my partner’s back when we first got it. It strikes a nice balance between comfort and support, especially for the price. For a busy household and kids using it regularly, I think it’s a solid option. Just keep in mind that like most mattresses, it may get softer with time.

Having been a loyal Zinus customer for several years, I have consistently found their products and packaging to be of high quality. Delivery and Setup (5/5) The mattress arrived securely packaged in its compressed "bed-in-a-box" format and was in flawless condition. Unboxing was simple, though the King size was heavy and required assistance. The mattress achieved its full loft and final dimensions within approximately 24 hours. Performance and Comfort (4/5) The aesthetic and surface feel of the mattress are excellent. After a week of use, the most significant observation is its therapeutic quality: it genuinely reduces back and shoulder pain, exactly as advertised. However, I have noted that the mattress is less firm than anticipated. Although it does not retain body impressions, it does exhibit considerable sinkage under the weight of a 140 lb individual. This raises a slight concern regarding its durability and how well it will maintain its supportive qualities over an extended period without forming permanent dips.

I’m very happy with the Zinus Twin 8-inch mattress. It was easy to unpack, and it expanded to its full size within a few hours. The medium-firm feel provides good support while still being comfortable for everyday sleep. I use this mattress on a metal bed frame, and I added a plywood board underneath for extra support. With this setup, the mattress feels very stable and supportive, with no sagging. It contours well to the body and helps reduce pressure points, and I’ve noticed less stiffness in the mornings compared to my previous mattress. The mattress feels well made for the price, and there was only a mild odor when first opened, which disappeared quickly. Overall, this is an excellent mattress for the price and works very well with a solid support base. I would definitely recommend it.
