Rated 5 out of 5 by from BEST TOPPER PURCHASE EVER I read all the reviews before selecting this topper. The fact that the material is very sturdy was the REAL reason I bought this particular topper. I previously owned a foam topper (egg crate type) and it didn't last. I wanted something that was heavier in material and more durable. So thank you everyone for your comments and reviews. I took the bad reviews with a grain of salt. Sometimes we just get bad products. My topper had no smell what-so-ever. I did open it and let it setup for about 10 hours so the material had time to expand. I don't have money for a new mattress so this was an economical alternative until I could save up enough money. But now I won't need a new mattress for awhile. Great product! Those who are debating on which to buy - don't hesitate - this is a great purchase. A little pricey, but WORTH every penny. PS - the first night I had this on my bed, I slept for 10 hrs. straight and I have a very bad back!!! How's that for a review!!!!

Rated 4 out of 5 by from Improves comfort I'm using this w/ 2 other layers, + a very inflexible mattress, long story. It's a big help. Definitely worth it. One tip if you're using a lot of layers like me, and your fitted sheet won't cover them all or is tight, use a fitted sheet just to cover this pad separately on top. I know that sounds weird and not the best aesthetic choice, but it really improves the "give" and cradling effect, and keeps it from torquing because there is too much surface tension if it is pulled tight, as I was initially doing. I was afraid that not anchoring it to the mattress would mean that it moved out of place, but not so for me. Also, our cat liked to scratch a flat foam pad, but keeps claws off this one, though she enjoys sleeping on it. Finally if you are considering cutting the twin size to make it narrower, don't. I can see by looking at it that it was better to have an inch of uncovered bed on either side than to cut it, which would have compromised its integrity.

Rated 5 out of 5 by from Well worth the money My expensive mattress is only a few years old, but for some reason I just could not get comfortable on it anymore. Instead of spending more money on a new one I've been trying to make it more comfortable with plush, poly/fiber filled toppers, but they loose shape and go flat in areas where you need the support. I wasn't sure about the foam topper because it didn't look comfortable, but WOW! It's like laying on a supportive cloud! I didn't realize just how badly I was sleeping until I got this topper. I wake up refreshed with no aches, pains, or sore spots. I don't flop around all night trying to get comfortable, and the moment I lay on it I can feel the pressure and tension in my body melt away. As for the smell, I have a very sensitive nose, and I found it to be very subtle. I layed it out across my bed so it could fully expand since it arrives compressed, and by the time I was ready to make my bed to get in it (about 5 hours later) it smelt like a normal mattress. I love this topper and can't recommend it enough! I just ordered one for my mom and one for each of my kids. It's money very well spent!!

Rated 5 out of 5 by from So comfortable, no need to buy a new mattress! My husband felt that our current mattress was too firm. He was having shoulder pain from sleeping on his side. Before buying a new mattress, I suggested we try a mattress topper. The Isotonic Memory Foam topper was highly rated. That, combined with the JC Penney White Sale, made it an obvious choice. It arrived with a note suggesting we air it out for several hours before use. We did, and there was very little residual odor. The first night we slept on it, we knew it was the solution to our problem. My husband now comfortably sleeps on his side. I liked our firm mattress and this topper has made it even more comfortable. I was worried that it would make it too squishy, but it didn't. Also, I haven't really noticed that I feel warmer while sleeping on it (a concern brought up by some reviewers). We'll have to wait and see if it feels too warm in the summer months.

Rated 5 out of 5 by from works great! i had bought a new mattress but it is too firm and leaves me with sore shoulders and neck in the morning, so i bought this topper hoping for some relief and so far it has helped. i was worried about the smell, but it did not smell at all, i aired it out for 8 hrs and it was fine and i am very sensitive to smells with migraines and allergies. it came back to it's shape right away too. i slept on it the first night i received it and i noticed relief right away. i also got it on sale so i was very happy with the price! it's nice and thick and we will see about durability, but so far i am sleeping much better and wake up w/o my sore spots from the hard mattress. i am pleased with this product!

Rated 4 out of 5 by from Great Product... I dont know what the other person is talking about. Yes it came rolled in seran Wrap. Others come in plastic packages. And with any type of foam product you have to let it air out. The product states let it air out for about 8 hours and the new smell will be gone. I di that and it was gone. I measured mine as well it is Two inches, not quite sure what instrument the other reviewer was using. It is 2 inches. I have lower back issues. and after the first night I could tell a difference in my lower back the next morning. Please disregard the other review, because the person has not reserahced foam at all. I have a couple of foam pillows and it took about 24 hours for the new smell to go away. ANy foam product will have that smell for a short time.

Rated 2 out of 5 by from Not the Topper for Us I suffer from hip bursitis and have pain during the night. We have a Sleep Number bed and I always keep my side much softer than my wife's in an attempt to alleviate some of the discomfort. After much research I talked my wife into our buying this topper when it went on sale, since I had read in other reviews that it helps hip pain. As others have commented, there was a strong odor at first, but that left after an airing in the garage. Of greater concern is the topper being at least three inches narrower than our queen bed, as well as shorter. On checking the enclosed sheet listing the dimensions of the various sizes, it appears that ALL are a bit smaller than standard bed sizes. I'm surprised more people haven't commented on this. Even so we could have adjusted. But, after eight nights we removed the topper, since my wife was having physical issues because of the softness. And, my sleep was more restless, with no relief from my bursitis. In short, it was a disappointment. We gave the topper to our grandson for use on his bed whenever he is home from college, since he said he likes soft mattresses. Obviously this topper works well for many people, but not for us.

Rated 5 out of 5 by from Awesome Topper - Would Highly Recomment After reading the reviews on this product, I decided to take a chance. I have to say, it totally exceeded my expectations. I got this on sale for half price, and it is totally worth it! It makes my bed extremely comfortable - my husband says we sleep on a cloud now! I followed others' advice and let the topper air out for a day before putting it on the bed, and didn't have any issues with odors. I have chronic lower back pain, and in the two months since we purchased this topper I have to say my pain has subsided. I wake up feeling refreshed, and my back doesn't hurt in the mornings any more! My only issue is that the queen size doesn't fully fit on my queen sized mattress, and while it's not too big of a deal, I'd consider getting a size bigger next time.
