Sofá (Greater Leys OX4)

Its an old sofa (+15 years) - firm and solid, no sag in the seats and no damage to the visible part of the sofa. At some point i tried to tip it upside down and broke the left back leg off. My son fixed that and it is very solid and stable, but the material underneath the sofa is badly torn (so he could reach leg) - its perfectly usable as is/cant see the torn material, but if you have reupholstery skills this would be a great one. I am not sure about the fire safety label (it probably had one when I got it, but don't want to try and turn it upside down again - same reason I can't actually take a photo of the damage.
