I've been sleeping in my office a lot lately. My home environment is far too noisy. Now I would love a sleepbox but yes I question two things: hygiene and noise. Hopefully it's well ventilated and there's no bugs but oh how I'd love a showerbox attachment. Also, how well does it isolate noise? Airports are noisy places. Does it isolate low frequency as well? If it does, I'd buy one for my terrible apartment.
