90. This couch holds an odd contraption of metal and wood. It's a 20-foot-diameter circular platform that is tilted heavily to one side. Beneath it you can discern mechanisms that seem to attach to a large crank not far away. Above the platform hang metal weights on thin chains, which in turn are attached to discs and belts that are attached to other winches. It seems as though turning the winches turns and tilts the platform and sets the weights to moving. This could be a training couch for combat. Certainly it would take a great deal of concentration to fight on the couch; perhaps it's a training couch for monks or spellcasters.
