Like a new bed.
Color: White, Size: Queen
Surprising how small the box it was delivered in. As the packaging is removed, the topper grows to full size. Easy to install. Very comfortable to sleep in. Getting into and out of a bed that is four inches taller takes some getting used to.

Overall decent
Color: White, Size: King
It smelled a bit “chemically” for the first few days. The smell did fade and eventually go away entirely. It also still slides off of my bed despite having the straps to hold it in place. Otherwise, I have no complaints. It’s extremely comfortable and adds a few extra inches to the height of my bed.
