I'm looking for some covers for our cushions so they're more to my taste / colour scheme.
I've seen several people have recommended Shein sofa / cushion covers but am a bit confused as to sizings.

We have a Troll GT 540 and I've been and measured all the various cushions.
The sizings on Shein are obviously designed to fit a wide variety of sofas but my question is this:

If a van cushion measures 65cm x 25cm but the nearest size Shein cover to that is 60-90cm x 30-50cm am I going to find there's lots of spare/baggy fabric or have people found that they fit nice and snug?

Thanks for sharing the pics of yours, they look really nice :)
