Size: Twin XL Style: 4 Inch
I have waited 5 months to leave a review. I wanted to make sure that all the bad reviews I read here were real or false. I have degenerative disc disease so I couldn't sleep in my bed with my husband anymore. I was sleeping in a recliner in the living room. I sell on eBay so I had an eBay room. With much discussion with my husband, we cleaned out my eBay room got me a hospital bed off of Facebook Marketplace and I finally ordered this mattress topper. Now it is important to tell you that I spent months researching mattress toppers. I read the good reviews and the bad. If I saw a common thread in the bad reviews then I didn't even think about going with that topper. Then I saw the video that Arzante posted with his 5-star review. I took a second look at this topper again. It was now at the top of my list. I received the topper a few days before my room was ready. So I was able to lay it out for a few days prior to sleeping on it. One thing I saw in several reviews on a lot of toppers was that there was a horrible chemical smell. Mine had no odor at all. That was the first thing I did when we got it opened was to take a big sniff and I didn't smell anything bad. I am a woman in my early 50s and I have horrible hot flashes. I also weigh over 250 pounds. I think it is important for you to know this for the second part of my review. I have read a lot of reviews complaining of the foam making them hot during the night or the foam flattened when used. This is why I wanted to wait 5 months to leave my review. I wanted to make sure I gave YOU accurate information. August in Iowa is unpleasant to begin with, but when you throw hot flashes into the mix it can be downright miserable. My wonderful husband put in a ceiling fan and a window air conditioner in my room. Along with an atomic clock that tells me the temperature in the room and what it is outside. I didn't have much trouble with being hot when sleeping with the topper. I was even using cotton sheets. Now it is Winter in Iowa. There are a few things I have figured out during my 5 months with my topper. Tencel or bamboo sheets are a must-have for those who run hot when they sleep. After the window air conditioner was taken out I did start waking up hot and had to uncover for a while. I am still using the ceiling fan and it helps. This is where the atomic clock comes in. I have also closed the vent in my room to our boiler so I get very little heat in my room. I prefer to go to bed when my room is at around 65 degrees. At times I wake up and my room is 71 - 73 degrees. Most days it is 69 degrees. With a room that cool and bamboo sheets I get chilled when I go to bed, but within minutes I am warmed up and perfectly comfortable. These are some of the things that I do to make sure my foam topper stays in good condition. At least once a month we strip the bed and flip the topper and make sure that what was at my feet is now at my head and the top is now the bottom. The topper is inspected for creases, rips, or tears. I have yet to find one. We also switch the hospital mattress from foot to head and vice versa. One of the things I was worried about using a foam topper was using an adjustable hospital bed. My head and feet are raised. What is this doing to the foam topper? Nothing. It is perfectly fine. This is important to know. When you wash the padded mattress cover DO NOT PUT IT IN THE DRYER!!! Let it air dry. We read the instructions and dried it on low and it seems to have shrunk a little bit. In width not in length. It is about an inch narrower on both sides now. This isn't a huge deal, I don't sleep on the edge of the bed. Also, twin XL sheets are not going to fit perfectly on this bed. We got straps that make the sheets tighter. Deep pocket sheets are not your friend with a hospital bed. This is my take on this topper. It is comfortable. I do feel like I am being cradled when sleeping. I don't move much in my sleep as it is a twin bed and when it is adjusted it is hard to sleep on your side unless you flatten the bed more. My back and hip pain has diminished. It will never go away fully, but I don't have to wrap a heating pad around my lower back for an hour after getting up just to be able to move. This is not a firm topper, nor is it is super soft. I guess for me I am Goldilocks and I found the one that is just right. At the end of the day, it is about your preference. This is perfect for me and if I ever need to replace this topper I will be buying this same one again. ... show more

Size: Queen Style: 4 Inch
This is the 3rd Mattress Topper I have owned, and by far the best. The two piece design incorporates the best of both worlds of memory foam support and pillow top comfort. I must admit when I first got it, it felt a little spongy, and it took several weeks for the mattress topper to fully blossom. I have a very inexpensive $400 mattress and with this VicoSoft 4โ€ memory foam pillow topper, I feel like I am sleeping on a $6,000 mattress or the same mattress at a 5 star hotel. Very smart to extend the trial period. Just be a little patient with it. I donโ€™t know why it needs time to fully blossom. It just does. The magic will happen. Best money I ever spent. ... show more

OMG! I absolutely love this topper. I am short so I ordered the 3โ€ foam or my legs would not reach the floor easily. It is perfect for me and I am thrilled with the way it cushions my bad lower back.

    • Comfort
Size: Twin XL Style: 4 Inch
Very impressed with the comfort. I was having hip pain and I am a woman who is in menopause. My hip pain went away after sleeping one night on this foam mattress. Trigger points obviously were the problem also my arms no longer fall asleep unless they are absolutely tucked under my chest. Which is just a bad habit of mine. Also, after reading one of the reviews I was sold when the woman said her night sweats went away. As long as I don't have a blanket on me only a sheet I do not sweat at night on this topper it is extremely comfortable !!! ... show more

    • Product does relieve hip shoulder and back pain
Size: King Style: 4 Inch
This mattress topper has done a lot to help me with my back shoulder and hip pain. Even my husband has said how much better he sleeps The only thing I do not like about it is that it has a very strong chemical smell even three days later it still hasnโ€™t gotten much better. Before making this purchase, I read all the reviews and the smell was a complaint for a couple other people, but then there were reviews that said their mattress did not have a smell the one that I received certainly does. ... show more

    • We are VERY happy with the pillow top on our new mattress topper from ViscoSoft.
Size: California King Style: 4 Inch
We are using this California king topper in our master bedroom. We saved so much over buying a new mattress. We fall asleep so much faster and stay asleep longer. WE ARE VERY happy with this selection. It is superior to our purchase of 2 previous toppers.
