Great hanging seat and perfect size!  I ordered the biggest size and it's perfect for my girls, age 12 but tall at 5'5".  I'm 5'10" and can also sit comfortably.  The bars under the seat can get a bit uncomfortable so we added a soft blanket under the cushion and it's fine now.  Nice quality and sturdy.  Large but the open nature of it doesn't look overpowering in their bedroom.  They love it!
