We bought too many of these and need them gone!!!! LifeStyle, now Rhythm Healthcare, has this Euro-style rollator that goes for $394 on Amazon. Their version of the upright walker has a bar on top that keeps this rollator sturdier than your typical upright walker. With the 10 inch front caster and 8 inch rear wheel, getting over threshholds or other-than-perfect terrain is a breeze.
