Purchased in 2022, the mattress was used for about 3 months, and the comforter was used only during the winter. It hasn't been used for about the last two years. Includes: mattress, mattress cover, comforter cover, comforter (thin?), pillow, pillowcase, sweat pad. Also, there is a new, unopened comforter, which is used in the winter with the thin? comforter, inside the cover. There are a few stains, but the usage period was short, so I think they can still be used!
