I’ve just bought a Simba Hybrid Pillow It’s very comfy. I have most of the stuffing in so it’s very deep but none of my pillow cases fit. I can get it in one but it squashed it all up and it isn’t as comfy. I’ve tried a boxwall case but that’s too small. I can see that extra larger pillowcases are available but they’re all long rather than deep. Any solutions?! (Other than sew my own...)
