This review is being written after 3 weeks of being used: I wanted to get a thorough review from my son on his experience as I purchased this for his dorm bed, which are notoriously not that great. He absolutely LOVES it and says he gets some really good sleep! It fits the bed perfectly and does not move around. The hybrid memory foam and pillow top style of this mattress topper provides the perfect level of softness yet is very supportive. I love that the pillow top portion is washable. I washed it before we moved him in for the summer, and it held up perfectly. The sheets we purchased still fit the bed with no problem at all. I have seen more expensive toppers, and I cannot imagine my son would get any better sleep then what he says he gets right now!

    Purchased the 3" foam topper and it arrived in a timely manner. Items were packed well and setup was easy. Only required unpackaging and spreading the foam and topper on the bed to allow for expansion and to beathe. There was no chemical smell emitted from either the foam or topper. Topper was well made, fit well and was secured in place by elastic corner straps and a deep pocketed elastic skirt. Only downside would be that you will need to measure your mattress depth since it adds height. After sleeping overnight the topper didn't slip, firmness was medium with softness. I had been experiencing sciatic pain and was pleasantly surprised to find that my overall stiffness and mobility was so much better than it had been after awakening. I feel this topper was and excellent purchase and will last and afford us a more relaxing sleep experience.

    I wasn’t sure this was going to work for me, but I tried it. It arrived in a pretty large box, but it wasn’t too heavy to move up stairs, it was pretty easy to unpack and lay out on the bed. I definitely let it lay out for at least 24 hours maybe even 36 if I can remember right. The foam part inflated a little bit after it was put on, then the white topping seemed a bit baggy, but it was ok because it fit great over my deep mattress with the topper. I am overall impressed. It’s extremely comfortable. It’s like sleeping in a cloud! It helps my nerve pain in my legs. I am just curious as to how long the foam with hold up. Overall it was a great price for the king size mattress topper, and I will hopefully be buying another one for another bed that we own.

    Update—— so weirdly enough I wrote this review above right when I put the mattress topper on my bed in August 2024 and was pretty much obsessed with it but now here we are not even six months later I think it’s actually been four months and every time I lay on the mattress topper it’s sunken in where I lay, I do expect it to happen but my back pain is back so clearly this is not working anymore, but it was good while it lasted I guess . I have rotated it two times since I put it on and it still sunken in an enough to
    Cause me back discomfort. Unfortunately I will not be keeping it that long.

    Size: Twin XLStyle: 4 InchVerified Purchase
    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.

    Wow. I feel like I got a $500 mattress pad. So thick and soft and I have had the best two night sleep. No shoulder pain and constant turning when on sides. I have bad disks in lumbar and thoracic, bad shoulders, ouchy knees, tendinitis in several areas and everything calmed down and didn’t need pain killers. Love this new purchase.
