I had a different brand of slip cover on my chair.   Hated it because it was too big, didn't fit right and always came untouched.
After a frustrating year,  I ordered myself a Christmas present, new covers! I have an oversized chair and I was so worried this wouldn't fit,  but it does! So happy!  I can sit down,  get up and not have to look back at the fabric mess cause for the most part this stays in place. 
And it's soft =)
