foam pad for seat cushion (Headington OX3)

This is to go inside a cushion cover on a small occasional chair. It is covered with the stretchy stockinette stuff which upholsterers use. It's quite firm, in clean condition. It's too thick and firm for the chair it's on, so has to go. 48 x 47 x 11cm. Might be helpful for an upcycling project or for use by someone who needs a quick fix for an armchair with a very low seat.
