Where can I buy foam or padding for benches

[madmum]

HI, I am trying to locate some foam or padding for 4 benches, I am trying (trying is defo the word) to upholster 4 benches for my wedding in May. All the ones on the internet seem really pricey and this is not the cost cutting exercise I had hoped for.

Anyone know of somewhere local I can get stuff from? Someone told me that there is a place in the Peckham market that used to sell foam? is it still there?

The Fabric shop on lordship lane sells the foam.

(The shop is Called Fabric), otherwise there is Dunelm mill..?
