My son purchased 2 rebuilt twin beds last year and had to exchange them due to the smell of urine.  I don't blame the furniture store for the smell, these are rebuilt beds that are wrapped in plastic so I sure they were not aware of it.   They did apologize and replaced both beds the same day.  My son is very satisfied with the quality and price.  I referred this store to my son because I have also purchased a rebuilt bed several years ago and was quite happy with it .  I have plans to purchase  a queen size one this month.
