Absolutely fantastic!
Color: 3 Inch Size: Full
It is a very comfortable mattress. I have a lot of trouble sleeping. I actually slept 7 1/2 hours. I usually sleep 3 to 5. I body wasn't stiff and sore like it usually is either. Great value for the money. Size as expected.

Great addition to your mattress
We bought a new Stearns and Foster queen mattress and wanted it just a little bit softer. This did the trick. Quite inexpensive, works very well and helps provide an excellent night of sleep.

Super comfortable
Color: 3 Inch Size: Queen
I’ve had this mattress topper for a year now and it’s still in really good shape. It hasn’t flattened at all, and it literally conforms to your body. I got the 3 inch thick one. You will get some of the best sleep with this topper. This topper could replace the thought of you getting a new mattress. My fiance says our bed is a trap because you will get stuck in it. Highly recommend buying! ... show more

An ok choice, not the best.
Color: 3 Inch Size: Full
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. ... show more

Perfect for the added comfort
Color: 2 Inch Size: Twin
This works well on my bed. It does shift. I have to adjust it once a week. Other than this, it is perfect.

Lasted less than 2 years.
Color: 3 Inch Size: Queen
While the topper was good for a while, it started to break down and split in the middle. Made it uncomfortable to sleep on eventually causing back problems. Not cooling at all sleeps hot.

Worth the money
Color: 2 Inch Size: Twin
I have a mattress that was just full of springs, so I found this memory foam that I thought was reasonably priced. It works really well! I also felt more comfortable sleeping.
