Definitely beats sleeping on the floor!
Color: Grey, Size: Twin
I was sleeping on the floor with my dog after she had emergency surgery and this helped me get through those tough couple of weeks. Comfortable and not too heavy. Comes with a bag to store it in and helps make it easier to move around.
