For anyone wanting a visual, see here: https://i.imgur.com/iUlSEU7r.jpg (Arholma on right, Froson on left) Stuffing the Arholma seat cushion into the Froson cover reduces its area by about an inch, while the back cushion cover's area is increased past the cushion about an inch. More on reddit.com

You take the old cushions to an upholster so they can be redone. It's close to impossible to find cushions for old pieces of furniture. They will cost you about 65 a piece. More on reddit.com

Outdoor cushions do seem to be ridiculously expensive! I just recover a lot of my cushions myself. My best project cost-wise was when I found a huge outdoor furniture cover at Ikea in the clearance bin for $9; I carefully took it apart at the seams, cut it to fit the 4 cushions I needed, and because I unfortunately don’t sew, used my hot glue gun instead. Turned out great and the fabric is higher quality than many replacement cushions I’ve seen for too much money. I’ve also just bought upholstery fabric by the yard and cushion foam at Joann or Hobby Lobby and it’s still much cheaper. More on reddit.com

I would recommend cushions made from fabric by sunbrella or another brand that has a crypton treatment. These will be water, stain, and fade resistant. I got some cheap custom ones made at coversandall.com. I think they have sunbrella fabric s as an option. You can do any size or shape and reuse your old foam insert or just buy some medium density foam at a craft store. Lots cheaper than buying new cushions. More on reddit.com
