3 Seater Leather Sofa (Matlock DE4)

SCS sofa approximately 6 years old. I’ve sat on it every day, so one end is slightly lower than the other as can be seen in the picture. Approximately 2m long (I measured including the arms)seat height approx 38cm. Front to back - including the back is about 97cm, seat front to back is approx 59cm
It is in fairly good condition, it does come from a household with cats. (In case anyone is allergic).
The only reason I’m getting rid of it is because I’m getting a knee op soon and need a higher seat. Still has its fire tag on.
Collection only and the back comes off to make it easier to move, but it is quite big and would require 2 strong people to move it.
