Serta Motion iSeries foundation and iSeries Twin XL Premium iFoam Mattress bed. Twin XL bed. Remote controlled be frame. Zero G setting. Box of extra parts (risers etc). Works well. Look at the photos. Mattress has 2 protective mattress covers on it. Set of Twin XL sheets included it. We used it for a brief time as a hospital (like) bed for my father-in-law. Clean and stain free.
