Ordered the twin medium memory foam 8-inch mattress for a daybed trundle in a guest room. I tried it for a night and it is very comfortable. The mattress arrived rolled in a box, was very well packaged and with no damage. The mattress inflated to its full size immediately. There was no odor and the cover was perfectly clean. First time ordering a mattress on line so I was nervous. No issues. I will be ordering a 10-inch Sealy for the top side of the daybed.
