I've never had a glider, I think that they are ugly and scream nursery, so too hard to re-function gracefully into our decor after the baby phase.
I have used the ikea poang chair, although I admit, it doesn't work that well for nursing a large toddler, more for the under a yr size.
My fav is my LANE leather recliner/rocker. DH and I fight over who will get this chair after it is retired as a nursing chair. So comfy and plush, if the baby spits up, it is easily wiped off, it reclines and rocks. What's not to love?
