Not sure is anyone is interested, but posting anyway... our first real mod is done to accommodate our 18 pound furry traveling companion... she demands to sleep at the foot of our bed, but the twins in Ollie aren't big enough. So added a 18x30 cushion between the beds for her. The support is light weight, fiberglass covered nidacore. It's stiff, flat, strong and weighs a little over two pounds. The support can serve as a table if desired, and the cushion can serve as a back support up against the kitchen counter when watching movies. The support stows under the mattress when not in use. It's short enough so that we can still get out of bed easily at night.
