I am sleeping more comfortably since using my TempurPedic topper. I am having to update my sheets, though, as the ones that I have been using do not accommodate both the mattress and topper. Overall, it is helpful for my comfort and improved sleep.
Comfy, the mattress top moves with night bed movement. If there was a way to secure the mattress top to the bed with elastic or something then it wouldn't be a problem for me. I have a thick mattress so standard sheets don't hold it in place either. Other than that the mattress is very comfortable. It's now on my pullout because returns are not allowed. Make sure you calculate the inches needed to have a proper sheet set that will secure the topper to the bed while you move at night.
The wife and I decided to buy one of the TEMPUR-Adapt + Cooling Toppers to help with back pain. We used it for about a month and then we had to remove it from the bed because it was making out back pain even worse. So what sucks is I spent almost $400 on something that made my back worse and I can't return it so it will just sit in my storage til I can find someone that might want it. So if you are buying this topper thinking you might need something softer to alleviate some back pain, think twice because it just makes it worse.
I have a full size mattress, so I purchased a full sized topper. It is too short and too narrow.... my feet hang off the bottom and the topper does not cover the entire mattress. A horrible very disappointing purchase.
The mattress is everything they say it is comfort-wise, one might even call it dreamy. However, don't waste your money on the cooling pad, it didn't help to mitigate the heat. the mattress is comfortable enough that I'm trying out cooling mattress toppers from other manufacturers,
Does not offer the support of the tempurpedic mattress. The cooling cover does work well, worth the extra money. However, the topper is so soft it just does not offer the same comfort as the full mattress. If I had known this, I would have ordered a different topper.
