Cushion pads for handmade cushion covers?

[PixieofCatan]

I'm crocheting some cushion covers and wondered if anybody could recommend some cushion inserts, I'm looking at these from Argos if anybody can say anything about them/has used them:

But I am open to suggestions!

I haven't used the Argos ones but my mum gets all of hers from Dunelm Mill. They have all sizes, different fillers (the duck feather ones are mums favourite) and you can buy them singularly.

Dunelm for me as well, lots of different sizes and fillings.

I ordered some of the Dunelm feather ones earlier in the year - good quality and very good value.

Dunelm for me too.

Okay, thank you all :) Any experience with the ones that aren't feather? My rats like to rip things apart and whilst I will try avoid them going near my cushions I also know that it'll inevitably get chewed and I don't fancy having to clean up feathers!
