After searching for months & reading reviews from comparable products till I was sick of looking & comparing I finally ordered this & was somewhat nervous that it wouldn't be as good a product as pictures online & boy was I ever wrong & in for an amazing surprise! Watched the videos over & over before I made my decision & this is the BEST decision I've ever made in my whole life! I needed to soften up a brand new Beauty Rest mattress I just bought at Rooms To Go for a guest room & I'm still in shock & amazed at how well made it is & how beautiful it is & I honestly can't say enough good stuff about this product! I'd give it a 20 if I could it's that good of a product! It's even more beautiful in person & is everything they said it'd be & then some! It's like laying on a cloud & the 4 inches brought my mattress up to a much better height also! This is well worth the money & as soon as I can afford it I'm going to get another one for my own $1,000 mattress which is already a pillowtop but nothing like this! I'm so happy I found this & btw it's also made in America which is another plus & explains why it's such good quality! If you're having any doubts at all about getting this topper & pad take it from me you won't be disappointed! If you're looking to soften up a mattress & like the luxury of pillowtop you can't go wrong with this one! Visco Soft has a great reputation & they answer your call (a real live person) & are happy to answer any questions you have. I am so happy I found this company & I just can't say enough good things about this product! It comes vacuum sealed & both are in separate bags & as soon as you cut the seal it expands into a beautiful cloud of comfort! I'm 72 & was able to do it by myself with no help & I still can't believe how wonderful & amazing this is! Don't waste any more time looking at other products. I did all that for you myself & I can tell you after ordering 3 other ones that aren't near as nice or well made & way more expensive you will not go wrong ordering this! It looks exactly like it shows online & you will not be disappointed! If you're concerned about an odor it has a very small odor in the foam when you first open it but it goes away after 24-48 hrs. I put the foam on my mattress & left it for 2 days to let it air out & then put the pad on over it & there's no smell & it's beautiful! Take my advice & get this & I guarantee you will love it! I took pictures but not sure how to upload them to show you. I can only say this is the best decision I've ever made.

I wanted this mattress topper because I’m sleeping on a pretty firm mattress that would give me some pressure points on my shoulder and hip (I’m a side sleeper). I chose it over other comparable toppers because I really loved the plush cover/fitted sheet that also straps around the memory foam layer so it could keep everything from sliding all around. Even though I was worried that it would be too soft for me, I pulled the trigger. As it turns out, it is more plush than I would ideally like for sleeping, but I have decided to keep it on my bed anyway. I spend a fair amount of time sitting/relaxing in my bed during the daytime, and it’s sooo comfy for that! Like cocooning in a cloud of feathers. Unfortunately that translates into some low back pain for me in the mornings. That’s probably partly because I’m a side sleeper in addition to the softness of the sleep surface. Overall I definitely recommend it. The company was really helpful to me when I reached out with a question, and the topper/cover are really nice and feel very high quality. 4 stars is only because I wish it was firmer for my personal taste.

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.
