This is my 3rd mattress topper this month! I have one in a queen and two in the twin sizes. Absolutely amazing! It will not disappoint you! Very easy to unpack and place on the bed. I didn’t take a picture of this one bc I was just too excited, but I may just undo the covers and post a separate review! It is long and wide enough. Definitely the best !

This is the BEST memory foam mattress topper I've ever had. I bought a 2 inch in a twin for a cot we were using as an extra bed and everyone went crazy over how comfortable it was. I loved it so much I purchased this one for my full size bed, but in a 3 inch. It is a total game changer. I want one for every bed in the house. These toppers are excellent quality. They come rolled up, but take no time before they are to size. They do not have a bad odor like most others tend to. I have had improved sleep and it has helped my hip and back pain so much. I wake up feeling better. The 2 inch is great, but I'm loving the 3 inch thickness. It seems to support me a bit more. It's such a great value and worth every penny! I LOVE this topper!

Size: Twin XL
Style: 3 Inch
Been using for 3 full months, didn't want to rush the review due to mixed reviews. I bought the twin xl size, and I weigh 200lbs give or take for reference. Did not have any of the durability or smell issues that other buyers reported. It is a medium firmness, I still think it feels soft, compare to a hospital style mattress. Definitely hardens if it's very cold, like most foams, so that is to be expected, but it's definitely not a true memory foam, bounces back to shape within 3 seconds of getting off it, and does not pass the "shake" or bounce test for spilling liquids like most true memory foams would. Cleaning instructions say to spot treat only, so definitely cover with mattress protector. Mine has some minor sweat stains after 3 months of use in hot weather. Gross, but not the fault of the manufacturer. All in all... good mattress topper, good value for the price, my girlfriend enjoys it also, although she prefers super firm bedding materials typically.

I’ve been looking for a replacement for my super soft 2 inch Walmart memory foam topper that I love and have had for years but because it’s been years I don’t know the brand to get another lol. I was eyeing this topper and got it on Black Friday deal which is exactly what I recommended whoever reading this to do. This topper is very dense, not hard but dense, I got the 3 inch full size and it’s definitely not as soft or slow to puff up as my old Walmart memory foam topper, one review before I got it said this topper is “medium- soft” I’d say it’s more medium and the surface is a little rough but the middle is softer, I live in a warmer area so it’s not the foam reactiving to the environment either it’s just not the softest topper in the world. I think because it’s so dense, not hard but dense, it makes my bed a little firmer and it’s definitely made my platform bed taller. It’s a very ok topper, not the softest or the hardest, get it on sale. I don’t “sink” in but I find it is slightly conforming to your body, it’s nothing crazy like a water bed, it’s just overall an ok topper.

I have bought a many mattress toppers over the years and most had many merits. This is by far the most noteworthy one I have purchased. I have Sever rheumatoid arthritis and struggle to find a reasonably firm mattress that is also rigid at its base and not too soft it worsens thing. I have given up on spring mattresses and use a combination of a traditional futon mattress along with some kind of topper to create the ideal bed. I have tried 4 different memory foam type toppers in the last 4 years that were all good in their own ways. They are somewhat Superior to down or quilted ones but not as cushy so I think both have merits. Sometimes I stack two toppers on my futon mattress. I have stacked three including a down topper. I’m happy to say this is No longer necessary. This topper is enough on its own so far. I’m hesitant to say it’s the best topper I’ve tried but that is looking to be the case. I can’t exactly explain why it’s so good but it might be the thickness and nature of the memory foam. All I know is I wake up refreshed but I don’t want to get up in the morning for good reasons. I used to wake up in pain. This is the opposite, so much So that I lazily drag my laptop into bed to do work for the first hour of the day. Not because I wake up in pain , which is the norm for me. I do it because I’m that comfortable. For someone who wakes up with crippling joint pain more days than not I can see that this is making a notable difference in my sleep. I can only praise this mattress topper as I use it with a futon mattress. I imagine it would be a welcome addition to anyone. It it has been a game changer for me.

Got the 3" Queen. Opening it up it was as wrinkled looking as a newborn LOL and had me a bit worried, but it fluffed up brilliantly in a few hours. This foam is one that feels a little firm at first, but softens when you lay down on it as your body heats it up, so don't be fooled by how firm it might seem at first - it is, but then it softens and you sink into it and it's so soft and supportive at the same time. I have 3 herniated discs and my old mattress and toppers were starting to break down (they had a good 12 year run, they earned their retirement lol) and got this and a new mattress. I've used lots of toppers - tried many over the years to help with my back and also shoulders, and this one is an amazingly good quality - it's what you want, supportive without totally collapsing it's just brilliant. I'm on the plus side so went with the 3" thick one, but folks of a regular healthy weight would do just fine with a 2" one. Fabulous purchase and worth every penny!

For those who have seen some of the review pictures of the topper wrinkled and too-short looking, that is only what it looks like immediately out of the vacuum sealed package. We waited just 10 minutes to let it air out, & it already looked full and covered my king size mattress. Comfort related, the mattress topper is too soft and squishy for me, but my husband loves it. Because the topper is thick and we already had a thick mattress, it makes my bed too high for my 5 yr to climb up on without jumping. This topper is best for one person, or if 2 people sleep on each side of the bed. I would not recommend if you and your spouse sleep side-by-side or if your youngest sleeps in the middle. If two ppl are laying down next to each other, they will sink down and upper body will be at an incline with legs up higher (it isnt comfortable). It is harder to move around. my youngest has woken up sweating since we put it on, even though it is supposed to be cooling. Do not get the 3 inch if your mattress is already somewhat new and soft. It would work only if your bed is rock hard before you get it. I now wish we had gotten the 1.5 or 2 at the most, in addition to the egg crate design (we got that one for my older son and it is so much better). My husband still loves how soft and fluffy the topper is. He usually wakes up with bad neck pain, but hasn't had an issue since we used the topper. He has gotten the best sleep in a long time. I have bad back pain and had a previous back surgery, so maybe that is why I don't like it. just beware if you are already in pain. If you like supper soft that molds around you, this is for you. If you like soft but some firmness, the 3 inch is not for you.

It gets warm, perhaps not as warm as some but I’m used to that and I’m ok with it. It puffed up immediately and had a slight offgassing odor. It’s looks good and has no flaws to see. I left it in an unused bedroom for a couple of days and it quickly lost the smell. It felt firm at first so I was concerned about too firm but no, when it warms up with me in it ..sinks a lot. I was concerned at first and not too sure about that but it’s working out well. Laying down in bed at night is very comfortable. I think I would prefer less of the sinking in where my heavier parts are, but. Gel does that. I weight 129 lbs and I’m short so, if you’re a larger sized person, it might sink in too much and you would need a denser topper. Overall I’m pleased and I’m keeping it and sleeping on it. If I decided in a few weeks down the road , that I would be better off on another topper, i’ll adjust my rating.
