We would sometimes swaddle our son and pop him almost upright into the HAB. We only did it before trying to get him to sleep in the evening so we could then take him out and lie him in bed. He was a shocking sleeper so he had his day sleeps in the HAB and would only go to sleep swaddled in bed with us lying with him. This way we were able to get him down for a little while without us. So, we only did it around the house, mostly even just the bedroom and I didn't feel he was as secure in there so I wouldn't have tried to zip around hands free doing things like that iykwim.
