This thing is solid, comfortable, and makes for a very flexible layout in the back of the van.
When it's just me and a bunch of gear, the solo bed is a fantastic option to maximize space and versatility. I secure it to the ceiling of my Adventure Wagon interior, or to the cutouts in my FVC bed when used below, with FVC cam straps with L-Track anchors and it works great.
I have a cam strap at the top and bottom set to the perfect length to keep the bed level, and then a third strap in the middle that I can quickly tighten to fold the bed up out of the way and then loosen to drop it back down.
This is a great product for a minimalist sleeping setup or to add bunks for kids above or below a full sized bed. I also have been exploring using it without the mattress for storage and just strapping pelican cases directly to it using the L-Track cutouts with FVC cam straps.
Overall: a super versatile product that I continue to find more uses for. I'd recommend having one in your quiver.
