After 3 kids and a dog our 10 year old leather sofas are starting to crack, they were expensive new and I wondered is there anything we can to get them back to looking as new again and how I would go about this? Do I go to a furniture restoration, could I DIY this? Ideally I wouldn't like to replace as they are so comfortable and nothing wrong apart from this. First picture is edge of seats where they have worn and the second is the arm rest and how the leather should be.
