IMHO this is not great advice. IKEA frames are not hardwood and not high quality. Also, reupholster is expensive - in my area, the labor alone is at least $1k and upholstery fabric is at least $30 a yard and up, 15 yards needed for a sofa. Most upholsterers can give you a general labor and yardage quote based on pictures, but anyone decent will strongly discourage you from reupholstering ikea unless it’s a DIY job.
