I found a really cool chair from Ikea called Poang. We bought 3 of them as we were updating our lounge furniture. I have one in the nursery, and 2 in the lounge. Everyone loves sitting in them. Best of all, they arent a 'breastfeeding chair and are quite funky, light, easy to move and come in a range of colours and fabrics.

They rock slightly - or bounce, but arent totally upright, slightly reclined but I used to pop a pillow behind my back in the early BF days for correct posture and positioning.
