I looked for a really long time for the right platform bed.  Finally found this one and it is perfect.  The foundation and material are very well made.  The back is enclosed and has a zipper.  The slats have worked fine for us but we just moved to 2 twin xl  adjustable frames (to make a king) from Brooklyn beds which fit perfectly.  Only adjustment we made was moving one of the slats for the motors.  Not they we needed the slats anymore, but we thought keeping them in place could/would keep the frame more stable.  So relieved after some of the posts on other platform beds NO bed bugs or cheap material issues.  Thoroughly happy with this purchase!
