We have a Mother's Choice Coco. It's not your typical frilly bassinette, and not on cheap plastic castors, which were the 2 main reasons that DH saw it and straight away said "that's the one". We were never intending to move it around the house, so didn't bother with one on wheels, but on the few times we did move it from room to room, it was light and fairly easy to carry. It's got a rectangle mattress and is a bit bigger than some others and our DD stayed in it for a good 5-6 months.
