I now have four.  Two at home.  Two at the office.  Easy to assemble.  Like, 10 minutes.  It is as if the dogs know the beds are for them.  They are greyhounds.  They stretch out.  They lay their heads on the soft sides of the bed, or they are on their back with 'crazy legs in the air'.  Adorable!  They always look comfortable. 

 I also have four people Casper mattresses.  Love them.
