By the way, thanks for visiting our up-cycling news site
Redoing some seats, figured upcyclers could help me out. Keeping the old ones going is better than buying new.
Found an upholstery subreddit but it’s dead, so posting here.
I live in Hawaii, so my options to order upholstery foam are limited due to shipping. Basically, if it can be found on amazon prime, or home depot /lowes /costco /walmart.
I’m looking at three options for foam:
Replace the whole seat cushion by cutting up a mattress topper.
Topper could be latex
Or polyurethane memory foam
Or bolster the existing sagging foam with a thin <1″ thick of eva foam or also a thin mattress topper. This minimizes the amount of work I have to do, while still making a firmer seat.
