A simple picture (even a stylized, human-sized vector drawing) would put debates about whether this pod is too small to bed.
But if a dry and possibly secure pod was what I had available, I'd take it. If I had the choice of one that allowed me to move around more and stretch out, I'd take it. If I had the choice of indoor plumbing, heat, and so on, I'd take it.
