Queen Medium/Soft Mattress

King Koil Mattress perfectly great mattress! Has always been used with a mattress protector and just got disinfected for the sale. It's 3.5 years old, was originally bought for $2K. My partner and I are moving in and the medium is a little too soft for us. The Flemington has been discontinued, but this is the new model, essentially the same medium firmness mattress details here: https://www.fortywinks.com.au/products/mattresses-bases/comfort-plus-medium-qb-mattress
