Bests & Worsts Reviews from Amazon

02/20/2020 UPDATE: I bought this on October 31, 2013, and after getting it, I had several years of great sleep. However, in November of 2019, I decided to wash the cover. I'd not had any accidents/spills/etc to require washing it, but I thought I would after 6 years of ownership. Horrible mistake. When I took the cover off, the top layer of the mattress looked like it had been disintegrating or being eaten by something! I do not have bed bugs or any other bugs. I then noticed that there were all kinds of little white shards going everywhere. I was really perplexed. I put the cover in the wash, and I came to Amazon to see if anyone else had this issue. I saw tons of reviews related to possible fiber glass particles IN the mattress, and I saw some reviews where buyers had called the company and was told not to remove the cover because of fiberglass! After washing the cover, I put it back on the mattress and began shopping for a new one. Due to holidays/etc, it took a little bit longer to get one, but I did. Also, I had a horrible case of sinusitis/bronchitis over Christmas that I think may have been set up by the shards from the mattress going in the room. I've done a complete cleaning of my master bedroom, master closet, and master bath as well as taking the curtains off and washing them. I emailed Zinus, and I was told the following: "We are sorry to hear you are having issues with your purchase. Zinus complies with federal and state fire retardant (FR) regulations without using any harmful chemicals. Instead, we use a chemical-free inner covering woven from glass fibers and not fiberglass that surrounds the foam. Fiberglass are micro-spheres Staple (like rice grain) while the ones on our mattresses are glass fibers, these are filaments woven into the foam it self, which serves as the fire barrier for our mattresses So the outer mattress cover should not be removed, which would expose and damage the inner fire barrier. The use instructions on the mattress label warn against removing the outer mattress cover." ^^HAVING SAID ALL OF THE ABOVE, Below is my original review. Perhaps this review will help you..... Details: I am 5'10", 268 pounds, stocky, and was recently not-exactly-diagnosed with sleep apnea. My doctor believes I may have this issue, but without tests, hard to confirm. I had bought a Serta Plush Firm mattress that basically just got flat on top and was left with firm. So, my review of this mattress is based upon the following: 1) Ease of assembly/setting up: The box they put this in was not exactly super heavy but was awkward to move around. Once I got it out of the box and on the frame it was super simple to set up. Remember: The zippered side goes on the bottom! 2) Inflating: I received the mattress around 2:15 in the afternoon and had on the frame by 2:40 (note: That is only 25 minutes). It was fully inflated in just a few hours and I slept on it that night. If you get the mattress and it arrives after 7PM, let it inflate and sleep on it the next night. 3) Smell: Unlike others I did not have any type of overpowering smell. It just smelled "new." TIP: If you think you may be bothered by the new smell, run your sheets through the washer and use some Snuggle concentrated fabric softener. It's got a great smell and will counteract any "new" smell of the mattress. 4) Firmness: When you first crawl onto the bed it feels a little firm, but then you sink into it and it really does conform to your body. I always lay on my back and watch some TV when I first get into bed at night. The first night I turned the TV off and laid to my left side. I felt the mattress firming back up to conform to my body. 5) Adjusting: With my old mattress I had to toss and turn several times before I finally got to sleep. I ordered this mattress on Halloween and it arrived 2 days later thanks to Prime. Every night since (over three weeks now) I got this mattress I roll over after turning the TV off and I am asleep within 5 minutes! I have not had to toss and turn any night since to get comfortable and fall asleep. 6) Other: With my old mattress during the day I was constantly having to turn my body to try and "pop" the bones around my lumbar area. I'm not doing any of that any more. Also, I would wake up previously and have to stretch my legs and they would just pop from no getting good support. They are not doing that any longer, either. 7) One person said you may not need a pillow and I think another said you will not need two pillows. I am not so sure about the no-pillow option but two will definitely not be needed. I bought a memory foam pillow a few months ago at Belk. It was an Isotonic something or other, and it has relieved all of my neck pain. It was the precursor to getting a memory foam mattress. 8) Heat: I have not had one problem with heat, and I am hot natured. I have bamboo/rayon sheets and they are very breathable and soft. I have an alternative-down memory foam comforter on top of that. I keep my house around 65 year round. 9) Overall: I would recommend this mattress to anyone who asked, and I would purchase again if I had to do all over again. I hope this helps. Any questions? Feel free to comment and I'll be happy to answer! 10/18/2014 UPDATE: Almost one year later and I am still loving this mattress! The side I sleep on has held it's shape greatly. I am thinking about turning it around on Halloween (1-year- anniversary) to see how the other side compares since I have slept on the same side a whole year. As of today (10/18) the mattress is on sale for almost $100 off! You can't go wrong with this mattress. Also, about the heat: I dropped the bamboo sheets as they were crap! Going back to regular cotton sheets was a tad warmer, so just lower your A/C at night and you'll be fine!
