Eleven Guests In Ten Beds

A small hotel has ten beds. One evening, eleven broghrers show up at the hotel. Not wanting to turn any of them away, the hotel staff comes up witha brilliant solution. He asks the first two brother to lie in the same bed temporarily. he then puts the third brother in the second bed, the fourth brother in the third bed, the fifth brother in the fourth bed, and so on, until he puts the tenth brother in the ninth bed. that leaves the tenth bed free, soo he then goes to fetch the second brother from the first bed and allows him to sleep there.

Describe why this is or is not possible.
