The pillows have less filling than expected. They are supposed to be firm. Some of the corners are actually empty. I suppose the stuffing might shift to fill the empty spaces, but they won't be firm in that case. I've bought this brand before and did not have this problem. I don't feel like returning, so I think I'll open up an edge and fill up the empty parts with stuffing and then sew them closed. This will fix the problem, but it would be nice if I didn't have to do this.
