I have been researching mattress toppers for months now. My requirements were not have to “wash and then dry in the sun”, no chemical smells, accurate description, skirted not elastic straps, washable and able to dry in dryer.I received the topper today and it’s definitively as described. I am laying it out until tomorrow to see if it puffs up some more. I stayed at a hotel this weekend. The beds had a toppers on them and this solidified my decision why I paid a higher price for a quality mattress topper.I can already tell it’s going a make a huge difference. I have quality mattresses, just old bones. Of course, now everyone in the family is going to want one. Will update my review to reflect sleeping on it for awhile. But so far very pleased.It isn't as fluffy as i wanted it to be l, but it does relief some of the hardness my bed has. I probably should have purchased a thicker one, because I need a little more relief from my hard bed than this can provide. But it came preached, neatly packaged, and it seems to be really good quality.I liked this product very much it’s fill is just right soft,and comfortable keeps u warm in Winter and to me works well all yr round I went back and ordered a second one some the filling bunches in the quilt and this did not that’s a plus especially when you wash it all stays in the right placesI used a bed that had this mattress topper on it when I was visiting my sister and really liked it! I have a firm mattress at home and bought this topper for it after returning from my visit. It really adds a lot of comfort for me, especially at pressure points! Love it!I like that it is thick and it is cool. Comfortable but I thought it would just envelope me in comfort but that could just be my bed underneath which is too firm.I initially bought it for my mattress and my rotator cuff issues. I sleep so much better now. Bought 2nd one for guest bed and I have one more to go!I have a Casper mattress (king size), which I wish I never got because it's way too firm. This is coming from someone who used to leave the bed to sleep on the floor when I couldn't sleep. So yeah it is really firm. I immediately got a 3" foam topper from Amazon, which helped, but it's extremely hot and still not comfortable. To top it all off, I have to use a waterproof mattress pad because of my dog. I use a "breathable" bamboo one also from Amazon. I was pretty sure the heat was from the 3" foam topper, despite that being labeled "cooling"For a year I have been struggling with a too-hot, uncomfortable bed, but I cannot afford to buy another mattress. We had already returned one before this and it was an ordeal.Ok so the Comfort Boost is definitely a mattress TOPPER, not just pad. I would say it's both. When I opened the box, I thought I'd toss it in the dryer to fluff it up, but it took up the entire dryer so that didn't really do anything. I suspect if I wash it, I will have to hang dry it or take it to the laundromat. It will fit in my washer (no agitator) but my dryer is too small for the king size.For the first night we tried just putting this over the mattress, with the waterproof pad over it. We both had an awful night's sleep and both woke up with lower back pain. My husband always has aches and pains but I woke up multiple times with very abnormal pain for me. As soon as we got up we put the 3" foam topper back on, with this over it, then the waterproof pad. The waterproof pad and the tight fit of the sheets thanks to all the layers squishes this down a bit. But it felt comfortable. That night, I was back to no back pain. My husband was so upset from the night before, he slept in the recliner in the living room. He was reluctant to go back to the bed. I have used it a few nights now and noticed that it DOES help with the heat from the foam topper. So my 3 stars come from that aspect of it. I would give it 5 stars for cooling. Even with the waterproof mattress pad, the bed is no longer too hot.It seems like a really great, quality product, but on it's own it really didn't do much of anything like to add a pillowtop feeling. Despite it looking like it has quite a bit of loft. I had to add another entire product from the same price point back in. Also luckily my favorite sheet set is really deep pocket and fits over all this, my other sets do not.The fabric is nice and everything was clean and crisp, with no smell. May require a trip to the laundromat to wash and dry the king size.Fit my queen size bed perfectly. Very thick and comfortable. Love it!
