Sleep Number P5 Queen Mattress with Flexfit 2 Base

This is a Sleep Number P5 Performance Series bed with Flexfit 1 base. The bed was manufactured less than two years ago but my grandmother bought this new and only used it for about a week. The bed and base with their components are all in perfect working condition and look like new. The bed has two separate air chambers that can be adjusted separately using the remote. You can also use the remote to raise the head portion of the bed as shown in the photo. I am asking $1,300 for the mattress and base together. The air chambers are deflated in the photos causing the mattress to look a bit saggy. SERIOUS INQUIRIES ONLY AND ONLY CASH WILL BE ACCEPTED.
