Count me as another who absolutely LOVES the HGI adjustable beds.^ I think it is one of the chain's best features.
I have stayed at many HGIs in the last 5 or so years and have only found one that was broken (at HGI 35th St. NYC). I am actually typing this from an HGI where I have spent the last 5 nights so my memory is fresh.
Yeah, I looked into the prices for one and they are a bit expensive at retail ($4,500 for the size I wanted). I assume HGI gets bulk pricing.
