There is NO REASON to pay the inflated prices for the other mattress toppers on the market that are exactly the same. The one we ordered is 3" thick, memory foam, soft (but not extremely so), and fit our full/queen perfectly. I have extreme pain from chronic disease, and this topper alleviates all of it. It sleeps cool, which is a plus considering my fiancé and I cuddle up together in our sleep. After sleeping on it over a month and a half, it is extremely durable, and hasn't shown signs of any wear and tear. It makes zero noise. It did take about an hour and a half to "fluff up" to full size once it comes out of the box because it is memory foam and ships compressed, but it didn't have any strange odors except maybe some mild plastic odor from the packaging around it. I would highly recommend this, and I have tried the 300$ competitors. You won't regret this purchase.

Bought it for my granddaughter. She was so happy with it. She is in college and lives on campus. The mattress’s are not comfortable at all and getting rest was so hard for her. She has thanked me over and over. I am 100% satisfied . College bed size is twin x-long

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 really like this twin sized mattress topper. When I first bought it, I was worried it was too small for my twin bed. However, after 24 hours, it fully expanded to the correct size. It turned my hard memory foam mattress into a soft cloud, and I really love it. I got the 4 inch kind, which I was hesitant about because I thought it might be too cushy, however, I’m very happy with it. It did take a couple of days for the chemical smell to dissipate, but now it’s fine, and I absolutely love it. It makes sleeping on my side easier. I also bought a softer memory foam pillow to complement the softer mattress topper. Others in the reviews have mentioned that the topper can rip easily, and this is true— it is heavy but delicate, so when you lift it to place it on the bed, be careful not to let it tear. However, now that it is on the bed, it is fine. This was a great and relatively cheap investment. I have had the topper now for several weeks, and still love it.

I bought this to ease the stiffness of my mattress and it’s perfect. No smell, comes up to size overnight and fits well. I hesitated to order it for fear of having to pack it up and send it back. Nope, it’s staying

I couldn't find a twin bed that was the right size to replace a cheap spring mattress. Figured I'd try a topper in the meantime. Now I don't have to buy a new mattress! I bought the 2" model, which is very comfortable. I can only imagine the 3" would be more comfortable. The cover saves you $ and time. Well worth it.

Just got this. I wanted something fast and they have the same day delivery( which is awesome) but there weren't many same day to chose from. I prefer a 1 or 1 and 1/2 inch but when you put it in the search all sizes come up. I've been using the toppers for about 8 years when i traveled at first and then on my home bd because it may have been a little too hard or soft? i'm bad at figuring if something is too soft as today beds are hard and soft. Anyways.. The packaging was nice. I was surprised it fit in that tiny box and it was really hard to get out tho I've only used it one night I fear it's too tall. The taller ones ( imo) don't add the same support? I still feel I sunk in too much and still have pain and had a hard time sleeping tho it was definitely cooler than regular memory foam. I may order one I don't sink into as much but the majority of people who aren't super picky will probably love this. Edit to add before I had gone to sleep last night I was adjusting it better on the bed and it tore in a small area. I've never had one tear except one previous one I bought and it was 6 months old and then after that it tears everywhere! One day?!? I'm now wondering if it was a brand new one ( even tho it was packed up well) it never had the slightest smell like all new ones have even if I didn't notice when I turned I could smell it but after a few weeks you don't notice but a 1 day ( going on 2 sorry) should have a slight smell ( all new things do) and it shouldn't rip for ages...
