Attaching two Paco Pads/RiverBeds/Landing Pads to make a double-bed
So I've got an NRS River Bed and an Aire Landing Pad (on order, both 3" thick) that will replaced a queen-sized air mattress. But, it would be nice to be able to attach them to one another to get closer to a double bed kind of deal, without them sliding apart.
Has anyone rigged up a system to attach pads when laid side by side? If so, how did you attach them? Was it effective at keeping the pads from sliding apart and creating a gap in the middle? Was it still comfortable?
I was thinking of a couple options:
1) Attach the two pads at the top and bottom using the buckles on the straps through the grommets. This could probably hold them together, but I feel like it might still separate in the middle.
2) Velcro. I was thinking I could glue on a flap to the first pad with a strip of hook-velcro on the underside of the flap. Then glue on a strip of loop-velcro onto the top of the second pad. The flap would go over the gap between the two pads and attach to the velcro on the second pad (see attached image).
