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!

I bought this for the guest bed and it seems to be quite comfortable. I've had it for several months but it's not used that much, so I can't speak to how well/ long it will hold up. It fits the bed perfectly and doesn't slide around. I would recommend it so far.

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.

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 LOOOOVE this mattress topper. I bought this over a year ago it’s still so nice. I sleep so well, it’s the perfect thickness, puffiness and support. I sink into bed every night and it supports everything perfectly.

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.
