I’ve chosen two M&S abbey sofas for the play room. I chose the same for the sitting room, ten years ago, and they’ve lasted well.
But this time I have to choose between memory foam and bounce back for the filling. I have no idea and my local M&S doesn’t have either in stock for me to try sitting on them. I’ve ruled out relaxed fibre for the filling, as I don’t like the slouchy look at all, and want something that will be both supportive and won’t need shaking, pillow style, all the time. But I don’t want too firm either!
