The hybrid rocker or Glider as it is properly known, masquerades as an armchair with the added benefit of a gentle rocking motion. I guess they are used most in nurseries for nursing mothers, but don't let that stop you.
Custom Design Presidio Glider, Serena and Lily
The absolute ultimate example of this design form is the Eames RAR Rocker. I have already stated my love of this chair here. So I won't say more than this...it has always been, and always will be my dream to have one of these beauties.
