Bests & Worsts Reviews from Amazon

[Edited 11/24/18 - see bottom] So, we have had this mattress for two years and noticed that it was getting lumpy. We could feel something knotted up under the cover. So I pulled it back to find that the firesock was in pieces and completely degraded. Now, I know what fiberglass looks like, I have worked with it in boats, cars, insulation, etc. This did not look or feel like fiberglass, it looked like fine blonde toddler hair. I started cleaning out the clumps of material that I assumed was some sort of a polyester fabric. I then got a vacuum cleaner involved to get the small stuff up. It was not until a bit of sunlight popped through the window that I realized the air was full of fiberglass particles. At this point I had been working in it and breathing it for at least 30 minutes. So I grabbed a high-power LED flashlight and discover that I was covered head to toe and our bedroom wall to wall in fine fiberglass. I previously had a more expensive USA made memory foam mattress and it was wrapped in what looked like panty hose material. We had slept on it for over 15 years and it had never worn through and it was not fiberglass. I discussed this with a friend of mine who works in the industry and he said that more brands than you might think are using fiberglass, but they are almost always the cheaper or over-seas manufactured stuff. He says that I should steer clear of any model that uses it because it simply will not last as I have experienced with this mattress. He says that fiberglass is cheap and will pass the fire certification test, but unfortunately there are no regulations that deal with the longevity or results of using it in a mattress. I have been ill for days coughing stuff up and feel like I have pneumonia. According to the doctor, it will clear with time but will likely leave some permanent damage. It is not dangerous in terms of coal mining dust or asbestos, but he says there is little research on its long-term effects. So if you have this mattress and it starts getting the lumps from the fire sock breaking down, just toss it in the garbage and move on. DO NOT REMOVE THE COVER! I know it has a zipper, just convince yourself that it does not. I do not remember reading anything about this when I received the mattress. I am looking for the limited documentation that shipped with it to verify if there were warnings about this. [11/24/18] We purchased a new bed, so while I was having this one removed, I snapped photos of the tags and have added them here. As you can see, it clearly says that the inner cover, known as a "Fire Sock", is made of glass. It also says that the outer cover is removable for cleaning. However, DO NOT DO IT! It only says not to remove the inner cover, but what else can you do if it starts breaking and clumping the way ours did? I am still having issues with breathing. I had asthma as a kid and have needed to use an inhaler a couple of times a week since this fiasco. I did find the original paperwork, but it was just instructions on how to allow the mattress to inflate to full size before using. I wish Amazon did not sell these and I am disappointed when I see similar ones at box stores like Wal-Mart. Buyer beware.
