I bought theses for my third graders based on description and some of the reviews that recommend for this age group.  They are WAY to small.  Getting them for first graders is pushing it!  Also you don't get all the colors shown.  I got 2 greens, 2 pinks, and 2 blues.  The rating is for the small size of the rockers and the fact you don't get all 6 colors.  Returned!
