Outdoor couch upholstery required

Wanting to get the cushions on the outdoor couch reupholstered. Don't have fabric yet, can supply if required. Looking for a simple result - don't require the piping as per current cushions. Just looking to get more life out of the couch as the current cushions are ripping with age. The inners are ok though. There are 8 soft back cushions, and 6 squarer seat cushions. All currently have zips that could be reused?
