Do you have a good back support pillow for when you nurse in bed or otherwise sit in bed for long chunks of time? I'd love recommendations!

Our plan is for lo2 to sleep in a bassinet in our room for the first few months at least, and we don't have room for a glider in there, so I'll most likely be nursing in bed a lot. I never really got the hang of side-lying with lo1, so I'll most likely be sitting up. I occasionally also work in our bed as well (our room is the only place I can "hide" from lo1 to work if she's home since otherwise she just wants mommy to play) and it kills my back, so I already could use something, besides just a mess of pillows, to help make it more comfy! I think I had one of those "husband" style pillows in college, but just a random one that I didn't love...
