I got the split king sized bed frame and they are  all that is advertised.  I am not sure how much I will use to massage feature but that will be decided on my next backache.

I have a bad back and had been sleeping on our reclining love seat to prevent back pain.  We bought these in hopes that it was the fact that in the bed I was laying flat.  Well two nights in and I I am extremely happy.

My side of the bed came damaged as there is a tear in the side of the fabric but that was from shipping not the product or Wayfair.  Also my husband's side was missing a holding pin for the I guess you could call it a motor to move the head of the bed.  I will reach out to customer service to get one sent.

Definitely worth the cost and in fact I have talked my sister into getting a full sized frame.
