Blow up beds are better

Blow up beds are better. These are barely thicker than a sleeping bag.

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.
