Rated 5 out of 5 by I sleep! I was about to buy a new mattress, even though mine is only a few years old. Tired of waking up sore and stiff, and finding new bed prices staggering, I decided to try a topper. I did have a good memory foam topper before. At least I thought that. I was waking up in the middle of the night, drenched. I actually thought I was hitting menopause early! ( I'm 48). Anyway, I ordered this one based on the isocool technology to avoid the "sleeping hot" syndrome. It works. I'm no longer in early I wake up refreshed and with no soreness or stiffness. A fun footnote: my dog, who sleeps at the bottom of my bed, used to get up and move or turn 15 to 20 times a nite. He does not budge now. Almost worth it to see his happy face! The only drawback worth mentioning is the smell. I aired it out for two days as recommended by others. It took most of it away, but I do still have a residual smell. I think it's from the isocool thing, not the foam. Anyway, way worth getting. February 12, 2012
Rated 5 out of 5 by Comfort, Wow! After waking up with my hands going numb or a crick in my neck, I decided to research a new mattress or mattress pad. I had a friend tell me about one she bought that helped her but that one seemed cheap. I found this one online and yesterday went to the local JCPenney and checked it out. We bought it and brought it home. I'm glad it was early in the day. I've seen in other reviews there was a smell issue with the foam, but ours had no odor to it at all that I could detect. And I have a nose like a coon hound. The foam mattress part was very tightly bound and I thought it would never plump to the original shape. After 6 hours and some pulling and massaging, it was almost perfect. The cost was well worth the product. Last night I had the most wonderful night of sleep I've had in a long time. No limbs falling asleep, no neck pains and I barely felt my hubby moving around, a great plus! We both slept like babies. Thank you JCPenney!! February 21, 2012
Rated 5 out of 5 by its like sleeping on a smushy cloud... :) I was a bit skeptical when I first bought it, I've heard a lot about how they don't last/go flat fast, but this one is better! It stays cool so I never Ever sweat at night, and its so thick I just sink into it. Not the kind of sinking like 'oh know I'm being eaten by the bed!' but a comforting, body contouring feeling that makes all the aches of the day go away. July 30, 2014
Rated 5 out of 5 by Comfortable Glad I purchased the Iso-Cool mattress topper. It arrived quickly & I was able to put it on my bed after a couple of hours. I unrolled & aired the foam outside over my swing because it does have an awful smell/completely gone after airing. It has been so comforable sleeping on it for the past 3 weeks. I sleep better & wake up with much less back & neck pain as I can expect with corrective surgery for 3 ruptured disc & scolosis from T12 to S1 & uncorrected scolosis & 2 riuptured disc C4 to C7. So I would think it would be heaven for anyone without these problems. I know my grandson loves it & says "it feels sooo goood". There is no motion from someone else sleeping with you like there was with my Serta pedic mattress & fiberfill topper. Well worth the price. Added bonus-I have not had any night sweats since sleeping on the Iso-Cool!! September 20, 2013
Rated 5 out of 5 by Just what we needed! After researching many products and reading reviews, I decided on this topper set. The features, sale price and free shipping made it an excellent value. We have had this for several weeks, but I wanted to use it before writing a review. It is exactly as described. The foam is soft, but not too much and it IS cooler, as promised. ( know what I mean!) The cotton topper is VERY nice!! So soft, and cool too. It helps keep everything in place. There was a new smell to it, but certainly not that bad! I opened up the foam and laid it out over top of some furniture, turned on the ceiling fan so that air could circulate around and under it. It puffed up/out within a few hours and the odor was completely gone by morning. I washed the cotton topper before making up our bed. It washed/dried perfectly. (It didn't really need it, that's just my preference.) Wow! Way better than the older foam topper! I actually slept for 6 hrs that first night! I have several painful issues and this topper does help to relieve them. Especially my hip pain, as I am a side sleeper. So yes, we are very pleased with it and do recommend this item, if this is what you are shopping for. Just be sure to let it expand and air out per instructions. I just thought of one more thing to add for what it's worth....we received this in only 3 days after my online order. And the manufacture date on it was April 2014. Maybe since it was so new, is why it didn't have the strong odor that others experienced...? July 23, 2014
Rated 4 out of 5 by Great for Preggos I bought this on sale because I was 12 weeks pregnant and our mattress was causing me major pain in my hips. This mattress topper is thick enough and provides enough cushioning that the pain has gone away completely. I'm not sure that we'll continue to use it once I'm no longer pregnant, since my husband finds it to be way to soft for his liking, but I know I wouldn't be sleeping as well as I am now if we hadn't gotten it. One thing that wasn't great about it: the smell. We left it outside to off-gas the petrochemical smell it had. It was fine after a day. June 25, 2014
Rated 5 out of 5 by This topper is DANGEROUS!!! Yes, dangerous! My mattress is an ancient wreck, but I couldn't spend the money on a new mattress right now. The answer - this mattress topper! The perfect thickness, easy to put on, and I didn't notice any smell at all! The only problem? Instead of awakening each morning bent over in back pain, I now fall asleep within 15 minutes of lying on my bed. No matter when! It's like having narcolepsy! I lay down to read and I fall asleep. I lay down to watch TV - yep, I fall asleep! And not only do I fall asleep - I sleep for 6-8 hours or someone wakes me up! From a woman who couldn't get more an an hour or two at a time and then awakened in pain - believe me, this topper is DANGEROUS! December 14, 2011
Rated 2 out of 5 by I did not like this because I felt hotter at night instead of cool. The topper is very heavy and I bought it because I have back problems as well as hot flashes at night. I did not feel cooler sleeping on this mattress so I returned it to the JC Penny store. June 25, 2014
