Awesome
Size: Full Style: 3 Inch
So, I needed this in a hurry because my old Sleep Number mattress’ air chambers broke off from the bed and my bed legit broke in half (it’s a long story lmao). Anyway, this foam topper is awesome and just what I needed to sleep somewhat comfortably until I am able to afford a new mattress. Super soft and comfortable, and like other reviews said, it’s like sleeping on a cloud. Nice 👍 ... show more

comfortable matress
Size: Full Style: 3 Inch
This is a great mattress topper for maximum comfort. I bought the 3-in version for a full-size bed for extra squishiness and softness. When it came in the mail, I thought it was pretty small and kind of stinky (like it just came from a factory kind of plastic smell), though. Don't be alarmed if it doesn't look like it will fit. I had to air it out and leave it laid out for about 2 days before putting sheets or blankets on it so it would expand and become a full-size topper (& less smelly). Also, it's pretty sturdy for less spillage or slipping ( but not to the extent of someone jumping on it, of course). I love it so far, though! It feels like it has reduced my tossing and turning at night. ... show more

I like this better than cotton fill type mattress toppers
Size: Queen Style: 3 Inch
For years, our trusty cotton fill topper had served us well, but the threads started to snag against our skin and the stuffing started to bunch up and it became very uncomfortable to sleep on. It was time for a change. After diving into the latest offerings, we landed on this firm yet surprisingly cozy foam topper. It molds to our curves like a gentle hug, but with enough support to keep us comfortably aligned. The difference has been nothing short of impressive We sleep deeper, wake feeling more refreshed, and those nagging aches and pains seem to be dissipating. It's only been a month, but this topper has already transformed our sleep experience in ways we never imagined. ... show more

Very Comfortable, Great Value
Size: Queen Style: 3 Inch
The item shipped incredibly fast. So much more comfortable to sleep on than my mattress previously was without it.

Amazing!!
Size: Queen Style: 3 Inch
This was so worth it. It’s so soft, plush, and cushy. It might be too plush, soft thick memory foam for some people, but not for me. It is also warmish and not cooling, but I’m always cold, and I like that. I don’t like eggshell memory foam toppers, so I got the normal flat 3” thick with no cover. I purchased a terry cloth, waterproof mattress protector to go over the topper and my mattress. Everything is perfect. Seems even thicker than 3” thick memory foam also. Good buy!! I love it. So cozy. ... show more
