Cushions replacement for rattan set

[Bedofroses85]

Hi,
a few years ago I bought a rattan set for our conservatory. It’s called Tuscany Richmond and it’s the typical corner seating with square cushions for sitting and rectangular for the back and a couple of benches. After so much use the cushions are looking quite bad and are uncomfortable. Covers are washable but inserts have almost disintegrated.

Can any of you help with ideas to replace them? At the very least the inserts?

I originally bought from an online company not longer trading and can’t see an easy option to just buy a replacement set without spending almost as much as what I paid originally for the whole thing!

Thanks in advance

What are the inserts made of? Could you fill with made to measure foam, purchased inexpensively online?

I've seen replacement sets on amazon, wayfair and gardenista. I haven't bought as we rescued ours so can't personally vouch, but might be worth a starting point for looking anyway.

this company were v helpful when I replaced my sofa foam recently

Thank you so much for the ideas! Yes I can purchase foam and will also look at the sets from Amazon as the covers are not looking great even after washing them!
