Mazda 2 2019 headrests

Does anybody know where and if I can get adjustable front headrests for my Mazda 2 in the UK?
I’m 5’1” and the headrest pushes my head forward. I like to sit fairly upright for my back, tilting backwards is not an option as not comfortable and restricts my forward vision.
I’ve had to buy a back cushion to push my back forwards away from the headrest, but this is not ideal and I don’t get the benefit from my heated seats.
