We are enjoying the adjustable bed, we opted for single controls as we have one on our Queen in our other bedroom and we both are quite synchronized in our sleep choices.  If not opt for the two bed system.  We love the flexibility choices both head and foot, a necessity for us.  It was very easy to set up, the only thing we needed was another 3” height leg extension which can be ordered from the manufacturer.  Without it we find it quite low.  They also have the fasteners to attach the frame to the headboard which we ordered as well.  Great quality and very good price.  Delivery was challenging as it always is coming from the US into Canada, the tracking goes awry when it goes to a third party shipper.  But all in all we are very happy with our choice.
