Our cushion inserts are custom made in Vancouver with Canadian sourced feathers.  They are generously filled as we like our cushion covers to be full & firm and we use a heavy 280TC cotton shell - so the feathers won't poke-through.   We fill our cushion covers with an insert that is one size larger.   For example - a 20"x 20" cover will take a 21"x 21" insert etc.
