It’s like a nice hug.
Size: Queen
I find this mattress pad very comfortable to sleep on. I originally bought it because my mattress was too hard. The mattress pad solved the problem. It’s nicely quilted making it very cushy. I’m very happy with it.

Fixed my aches, real improvement in sleep
Size: Queen
It actually does make my bed feel better.
I was skeptical, but decided to try it because our mattress isnt very old but I wake up with aches in my hips/lower back. When I got it, I thought no way this works. But it does.
It goes in like a fitted sheet, super easy to put on. And I honestly havent woken up with hip or lower back aches since using it. Had it on our bed for about 2 months now.
I read some people say they sleep hotter with it, but I havent noticed that at all. Temperature feels the same as without it.
So glad I tried this before spending money on a mew mattress!

Best Mattress Pad!
Size: Queen
This is the best mattress pad you are going to find anywhere and the price is actually a bargain compared to all the other mattress pads I saw in the stores or online. Thought I needed a new mattress but all I needed was this comfy cover.

Comfortable!
Size: King, Unit Count: 2.0
After vacationing, I wanted to buy the brand of pillows used at the resort where we stayed because they were so comfortable. I landed on these pillows instead because of the reasonable price point. These pillows are every bit as comfortable. They are fluffy and supportive without being too heavy and stay cool. These pillows are comfortable and well made. They support both my head and neck and e long enough to use as a body pillow for side sleeping. I would recommend these pillows!
