I love this bed topper! You can use it on any type of mattress, it soft and helps with my back I have scoliosis and this works amazing and helps. I don't even need a pillow because it's so cushioning and comfortable. It doesn't overheat you so you don't and overheat at night. And overall this week quality is amazing as well as the durability.

So far so good. When I got it I thought I might have to return it because the memory foam insert was about three inches wider then it should be. But it has not been an issue once I placed it into the topper and put the pad on the bed. The topper is made like a fitted sheet with ample room to fit the memory foam insert and my 10 inch mattress easily. So it keeps everything in place. I have had no issues at all. The two inch topper is very soft and the added 2 inch memory foam insert makes it very comfortable.

The hardest part is finding a flat surface big enough to let it get air and expand. Easy to put on the bed after it expands and airs out. The quality seems good it's soft and helped make my bed more comfortable.

The Queen Duel Layer Mattress Topper is comfortable. I placed it on the bed before laying on it for over 24 hours. I'm able to get a good nights sleep.

I am very pleasantly surprised by this pad. My dogs ate the expensive top layer of my Sleep Number bed, so I was looking at a ridiculous price to replace the original. I was skeptical this would be thick enough of a cushion to go on top of the air chambers and still be adjustable for head and foot rise. Works perfect, and is very comfortable. Buy with confidence!

Thanks for inventing anf creating this product! I throughly enjoy ours!

Love this! So comfortable, good quality and a great price. Only downfall is that my sheets also slip off on the corners now even the ones that have the straps to keep them on. It has added a lot of bulk to the mattress. Was easy to put on and it does stay on well however.
