AMAZING. The non-toxic new smell airs out in a couple of days. It has made our meh mattress into an incredibly inviting luscious not too hard not too soft but just right cloud of comfort. It looks great, attaches easily, has no bumps, and supports our 70 year old backs. Plus, in a queen sized bed, I can’t feel my husband rolling around at night anymore. I recommend this, and I am sensitive to odors of new products—not this one. Plus it dissipates quickly. We love our ViscoSoft 4” Pillow Top Memory Foam Mattress Topper! Thinking of getting another for our other bed.

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.

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 bought a new, low end, extra firm beautyrest mattress 6 months ago which had great reviews saying it was good for back. Having disc, neck and vertebrae issues, I got it. It had a huge lump like it was folded when I got it. It was rock hard and felt like I was sleeping out in my driveway on asphalt. My back was getting ripped apart on it and I never felt worse. I could barely walk after 5 months on it. I couldn't afford to buy another mattress, so I figured I'm gonna try one more topper and if it doesn't work, I'm gonna have to go back to a waterbed mattress. I got a couple different mattress toppers, and I also already had a 4" memory foam one. All of them left me in horrible pain. I finally researched everything I could, and decided I'd be willing to spend a little more one last time and I could use it on a waterbed if it don't work. I don't know how long this is gonna last, but this topper changed everything. My bed, which was crushing my sciatic nerve cuz it was rock hard, is now comfortable and actually feels soft, but is firm still, unlike the other cheap 4" topper that felt cheap too. This topper has been having my back. I got some Beckham hotel pillows with it for my neck. I pray to God it lasts a long time cuz that mattress was a cheap piece of scrap and a huge disappointment for a beautyrest. I am so glad I got this. Trust me, all memory foam mattresses toppers aren't created equal. I highly recommend it. I like that it has the polyester topping too which is the main reason I got it. I need the down alternative cuz it's the best with the combination instead of just the foam. The price went up a lot since I bought it. I think they should put the price down, but seriously, as long as a person sleeps each day, I'm done with cheap mattresses. Your health is worth it. It'll save you $$ from chiropractor visits.

I purchased a new (very expensive) mattress that ended up being way too hard for me. I purchases one topper but it really didn't help, so then added two mattress pads that still didn't give me much help. I finally bit the bullet and decided to try this topper, based in part on the fact that it was a cooling topper. I sleep very hot and live in a climate with almost year round air conditioning so I am desperate to get cool at night. Health problems also contribute to my needing a bed that can cool me down. This topper set up is very heavy. I got the 4 inch version which came with the memory foam topper and the pillow top pad. Once you attach the pad to the topper and then pull the skirt around your mattress, it never moves. I had no issue with it slipping at all. I also had no issue with any sort of chemical odor or smell. I have severe allergies and migraines and after I unboxed it and let it sit out for several hours, I was able to sleep on it that night without any problem. The 4 inch topper set up completely solved my hard mattress problem. It basically turned my rock hard mattress into a new pillow top bed. It was like getting an entirely new mattress. It gave me the 'snuggle into the bed' feeling I had been looking for. I have back and should pain issues if a bed is too soft or hard and I now wake up without any back or shoulder pain. This won't be the item for you if you want something hard or very firm. But if you like a pillow top feeling, then look at this. I also have not over heated in it since I got it. It's not super cooling, but I don't wake up sweating, either.

I waited to do a review until we slept on this for a week. I am not getting paid for this review, just your average person. This is the best purchase! I have bone on bone knee pain and I have not slept this good in so long! I am not even using a pillow because this mattress topper forms around you and your joints will thank you! Recommended this to a friend and she also can't believe how comfortable this is.
