I love this thing. I'm 5' 3" and it is big enough for me to feel that it is surrounding me, but I imagine someone taller than 5' 5" might think this is average or small. It was a bit complicated to put together but the directions were clear. I had accidentally left the inside bag out for several days and it expanded so that made it harder, so I recommend that you keep this in the box until your ready to put it together.
