Hi Alice, I received enquiries like your everyday about how to make a bed softer. The good news is it is much easier to soften a bed than it is to make one firmer. All of our overlays will help to accomodate you with this and the latex overlay is probably the best. Please call us on 03 8585 6685 and we can have a chat about where you can view the overlay range. Warm regards Brett Parnham.
