I don't usually write reviews about the items I order online, but I feel the need to this time. I received my Dosaze topper last week, and having slept on it four nights now, I notice I'm sleeping through the night, and no more morning aches and pains when I get up in the morning. I had a minor knee injury a couple of years ago and noticed how my knee would be sore in the morning---that pain has almost completely disappeared. Never thought my mattress would be aggravating it, but the topper seems to have improved my knee immensely! Highly recommend this mattress topper!!!

Love it! Finally a good nights sleep which I'm haven't had in months, do to a hip injury. Great on my overly firm mattress. I like that I don't sink and I can easily turnover and move about, as I am usually a restless sleeper. Hurray for heavier density foam & cooling gel for my overweight body. Im not getting overheated as I have gotten on other mattress toppers. I'm sure the cooling gel helps but I also have a 3/4" cotton mattress pad on top. I hope to be able afford bamboo sheets in the future. But for now, I just care that I'm getting much needed sleep. Although cost is a big factor for me, I was willing to spend a little more for a chance at a good night's sleep. After the initial 24 hour airing out time, which to my surprise, there was minimal chemical smell; I was able to sleep on it. And to an asthmatic person that's very important. I've only been sleeping on the topper for a couple of weeks, so I will update my review later to let you know how the topper is holding up.

My Sealy Posturepedic was reaching the end of its life - it had started to lose support and I started waking up with allover body pains. Since this is 2020, it isn't an ideal time to go mattress shopping. Realizing I needed to do something, I finally pulled the trigger and ordered this topper. I let the topper air out for ~30 hours beforehand. It probably could have used a full 48 hours of breathing because I occasionally still smell a faint chemical smell, but I was anxious to try it out. Because I needed more support, I knew that simply placing the topper on top of an already sagging mattress top likely wouldn't make much difference. Following the lead of another reviewer, I flipped my non-flippable mattress first (a one-sided pillowtop mattress that is hard on the underside). That was the perfect suggestion to provide firm support and a nice cushion. The topper's corner straps are adjustable and snugly grip the mattress; I've never experienced any sliding or movement whatsoever. Despite claims of cooling, I do feel a bit warmer at night with this topper. But it's a fair trade for a more comfortable bed.

I have 3 herniated discs in my lower back. Pain from too soft a mattress caused me to overshoot on the firmness of a new one. Eventually I had aches from the new one being too firm. I sleep mostly on my side or stomach. Lots of choices in foam toppers and reviews are all over the place on them along with prices. I chose this one after finding reviews on it here and elsewhere from others my size (5'10" and 210lbs) with the same pain issues. Foam smell out of box was minimal - I aired mine out in the garage for about 8 hours in front of a fan. It fits mattress as it should. When laying on it, in any position, I never feel I have bottomed out or fully compressed the foam anywhere - in other words, I do not feel the mattress it sits on. I am back to sleeping well again and am very happy with the price to performance of this so far. Durability unknown, but based on reviews I believe to be accurate, I expect to get a few years out of this.

Ok. So I wanted to write a legitimate review as I almost did not buy this product because of the bad reviews. I was terrified that my apartment would smell musty or chemically and that I would be unable to fit the topper back in the box to get my money back. I researched an article that said to set a bowl of vinegar next to the topper while it was out-gassing to absorb the odor and, if that didn't work, to cover it in baking soda and then vacuum it up. I received the topper on a Friday evening. I placed it in the stairwell of my apartment building with the cover unzipped and pulled back. I flipped it over on Saturday evening, pulling back the cover to let it air out. Sunday was D Day. Did I just waste a lot of money that I will never be able to get back and be stuck with a queen-sized piece of smelly junk to get rid of? Nope. The topper is great. Never smelled a thing. Never had to resort to the vinegar baking soda tricks. Not sure if people aren't pulling back the cover while letting it out-gas or if they got particularly smelly toppers while mine is pristine and lady-like. Whatever the case, for the price, I'm very much enjoying this product. Not too soft, the cooling feature mostly works, the straps were not super flimsy like some of the reviews said, standing next to a ruler it DID reach a full 3 inches, and last but not least, there may be an 1/8th of an inch gap on one side of my mattress, but the size difference is not as dramatic as some would have you believe. I'd recommend this product to my friends!
