Rated 5 out of 5 by from LOVE, LOVE, LOVE Did I say yet how much I LOVE this topper? For 2 weeks I all of a sudden woke up with sore lower back every day. I slept on my daughters memory foam mattress for 2 days and was much better. I decided to try a memory foam topper since our bed is only 5 years old. After reading the reviews I decided to try this and its exactly what I was looking for. My husband who thought my soreness was "all in my head" really likes it also . I've been sleeping very well and no longer waking up sore. ***It only took about 1 hour to fully expand and it fit my king bed perfectly, BUT... If your mattress is already thick then you will most likely need deep pocket sheets. I had to buy some after I put this topper on***

Rated 4 out of 5 by from Sure beats purchasing a new mattress! We purchased this topper after reviewing several mattresses and toppers. We made a trip to Kohls and felt the display and determined it was worth a try. Our mattress was a nice quality mattress, but 7 years of use left us achy in the morning and restless at night. This topper absolutely offers some relief and keeps us cooler at night. We've become so used to sleeping on our mattress without the topper that it has taken some adjustment, but I would definitely purchase this item again. My only complaint is that the cover only has cooling effect in the center and I wish the entire cover had the same effect.

Rated 5 out of 5 by from An investment I was hesitant about purchasing this topper because I was concerned that it was a lot of money to spend on something that may not help me, but it was love at first sleep. My mattress is 11 years old, but purchasing a new one just didn't feel like an option. This topper has made my bed feel brand new again. I'm sleeping much more sound. I'm waking up and no longer feeling stiff and sore. It has made me feel alive. I would recommend this anyone looking. As far as other reviews, stating that they foam made them feel hot while sleeping, I have not had that experience. Overall, could not be happier.

Rated 5 out of 5 by from I did NOT want to like this memory foam topper,,,, But I LOVE IT! My husband had been thrashing about in his sleep, and our really good quality mattress was getting older,,but I was not ready to buy a new one yet. Reluctantly I thought, what do I have to lose? Anything to get a good night's sleep! It was amazing. First of all the memory foam kind of keeps you in place so hubby doesn't thrash anymore! That alone would be worth it, but it also had rejuvenated our old mattress AND I honestly sleep soo much more comfortably too! I used to wake up several times a night, no more. It's so comfy!!! I lOvE it!!!
