  • Un Boxing or Un Packing
Size: Twin Style: 3Inch
I was skeptic at first when I got the mattress topper. Please note to allow a full 72 hours for it to take its shape. I will let you know that leaving it out in the sun helped with the shaping of this mattress pad. Please try to give it a good 72-84 hours before making a decision to return the topper. I will say that I used this for camping and it is pretty comfortable onto of my blow up mattress. ... show more

  • One of the best purchases I have ever made!
Size: California King Style: 4Inch
I’m 25 and have extremely back pain. I would wake up every morning with my full body in pain, ache all over, take forever till I fall asleep… I could go on and on. This has made me feel refreshed and pain free ever time I wake up now!!! So happy I got this. Worth my money!

  • once it fully inflates, this mattress topper is one of the best I have ever tried
Size: Queen Style: 3Inch
I purchased this for a sofa bed, knowing how uncomfortable they can be. We took it on vacation with us since we were staying in a one bedroom, and I volunteered to be the sacrificial lamb to sleep in the sofa bed. the first night was strange as it was still not fully inflated. The second night it was heavenly (it became so apparent I was getting the best sleep in the family, I had people offering to switch places). And when they tried my bed, they did not want to get off it. My original plans were to leave this once my two week vacation was over, however, I've brought it home. This is honestly that comfortable - it now is a topper for the futon in my home office. ... show more

  • Nice quality
Size: King Style: 3Inch
I liked it came in a small box for a King size pad vacuumed sealed 2x3.ft if that .. What I didn’t like is the extra shipping and handling charge of $30 plus more shipping costs to get it here unless you choose to wait longer but still came pretty quick. It’s not oversize by any means so I don’t know why Amazon is tacking that on . This was used in a V berth on a boat over the padded bed area , cuts to shape very easy with a fillet knife to score the cut than I used a Electric Turkey craving knife to saw thru the rest . Turned out really nice . My idea of a very comfortable night sleep on the hook . Money well spent … ... show more

  • Solid Product
Size: King Style: 4Inch
I'm only giving this product 4 stars instead of 5 simply because there isn't much with cooling as it implied. These memory foam products are just hot. I've yet to find one that isn't. But this memory foam is super comfortable and sturdy. I've taking it off and on several times and it's help up every time. Like I said, the only drawback is it's super hot but get a good sheet set and that helps mitigate some of the heat. I recommend this product. ... show more

  • Perfect for RV loft and fold down “bed.”
Size: Full Style: 4Inch
Bought an ‘88 Minnie Winnie and needed a “mattress” for the loft bed. The 4 inch works perfectly, just cut it to size. It’s not just for the dog. But she dies love it, the spoiled brat. I am 5’8 and slept great on it. Working so well that we got another one for the bed that the little table turns into, much more comfortable than just the cushions it came with. I clean for a friend that got this for her bed so I knew exactly what I was getting, they are perfect. They can be easily cut to size with an electric knife. Seriously, do not cut it with anything else. Electric knife, it’s like butter. ... show more

Due lumbar fusion, I must have extra firm mattress, but it caused hip and shoulder to ache. This topper eliminated the aches, and now I get a good night sleep 😴

  • Difficulty moving on a mattress that is too deep.
Size: King Style: 4Inch
Because of a depth issue and cushioning, if a foam mattress is too deep, it will be too hard to move over on the mattress. Whether up or down or toward the middle of the mattress or to the edge, the sinking into the deeper mattress is like falling into a hole and trying to climb out. I don't recommend the 4 inch or deeper. foam mattresses. If you don;t like it and it is opened, it is impossible to pack back up to send back or vacuum pack it again. ... show more
