A good bean bag chair can last up to a decade at least! If you buy an average-sized one for a child then you may have to take into consideration the fact that your child will outgrow the chair. With multiple children in the household, there should be a pretty good turnaround. If the chair is more of a size that your child can grow into, then it will probably have a longer shelf-life! Overuse and over-washing a removable cover can wear the material thin. Also, after about 10 years of use, the filler may go completely flat unless replaced with new beads.
