Thank you for viewing. I purchased this new here around July of last year and used it for about 10 days, only at night, but I didn't continue using it, so I stored it. I'm selling it now while it's still in good condition. I don't know when the previous seller purchased it. I mainly used the right side of the bed, and I used the left side once as a trial. Everything in the photos is included. Operation has been confirmed.
