I have one from DS2 but bought it when preg as had horrible bad back and has been godsend with DS3's pregnancy BUT...
...found it difficult in early days feeding with both DS2&3 the arms got in way while trying to latch on my big baby. Almost bought another chair in desperation (sound like I'm made of money don't I but was just having a rough time establishing feeding with each of mine and the credit card was calling in middle of night!)
Wanted on of those specially designed BF chairs from Mothercare (but you can also by them direct) which are very low and have no arms. In the end went for a cheap dining chair and a pile of books in early days!
But for me the glider was fantastic when (big) got babies got bigger and I could feed with them in a more sitting up position. And if you do get one, make sure you get the footstool as well I'd recommend...
