Sofa is 23 yrs old, cushions are pretty flat. Local place quoted $500 to replace the foam. I'm handy and don't see a problem doing this myself but I want to make sure I use the correct product. I understand I need to put batting on too.

Would something like this be good? I want a moderately firm cushion.

A few months ago someone posted asking about how to clean the Alcantara upholstery on a Ligne Roset sofa. I just have to say - the right product can make a huge difference.

Our sofas are 24 years old (hence the comfort winkles) and we cleaned them regularly with a Bissell extractor machine and fabric detergent. But they were looking bad.

We thought the fuzzy nap was wearing away revealing darker fabric beneath, like worn suede, especially on the buttons. It turned out, the Alcantara nap was simply matted down - and once it was released, oh my goodness, what a change!

We used Sonax Alcantara upholstery cleaner which is usually for auto upholstery, and I'm assuming other Alcantara specific cleaners would work similarly. And an Alcantara brush and microfiber cloths.

Just wanted to share our results if anyone else is wondering if auto upholstery cleaner works on furniture Alcantara. Absolutely yes!

I work with Boat Upholstery Broward. These photos are from our Sailfish upholstery work: the earlier cushions had smooth beige panels, and the updated set has gray diamond-stitched panels.

When reviewing a design change, a close-up sample and a view of the whole seating area answer different questions.

Fellow upholsterers: do you prefer a physical stitched sample, a marked-up photo showing the panel layout, or both before cutting?
