Loose covers

Anyone bought loose covers from the likes of Plumbs?

If so, how was it?

Our bedroom chair doesn't go with the room now it has been redecorated. The chair is rarely used for sitting on but is handy for throwing clothes on.

The chair wasn't expensive - it's an IKEA armchair which is still available but in awful colours- but a replacement would be about £3/400 so I wondered if Plumbs (or similar) would be a good alternative.
