I gladly recommend these synthetic cushions. They are of excellent quality, there are cheaper, but better put a little more and have something that makes sense instead of crush and disintegrate. I wore linen covers size 45 x 45 also, and they are perfect for decorating my canapé.Pas one to crash, they are filled, and well bounce. I just have them, but I think they bear machine washing is not possible with the low end because the inner lining completely disintegrates or collects in a corner of the cushion.
