My sofas are still beautiful but after 13 years one base cushion has a worn area . I would like new base cushions or a refill and covers to match would double the life ,but sadly the fabric is no longer available through Duresta ,I have asked for the name of original supplier a porcelain stripe and a dragon design ,fingers crossed it has been a fantastic fabric for me .
