I had to put an extra pillow in-between the v at the bottom if that makes sense the part that ur back falls into and isn’t padded and also a pillow under my bum aswell. I found it easier sleeping on the sofa as well as there was no space to wiggle downwards or sideways xx
btw jo after 2 weeks I started lowering the angle now I still sleep on my back just with a lot of pillows not actually sitting up anymore im pretty sure that’s what the nurse said I could do but cant actually remember? xx
