These covers are giving me time to find the right replacement chairs for my recently painted dining table.  
Pros: They arrived quickly and slipped over my smaller, dark parsons chairs easily.  Even though I can't tuck them in at the back of the seat, they have a more tailored, neater look than the ones I had to buy for my larger parson chairs.  
Cons: I noticed the ones used most often slip a bit on a corner now and then; but are easily adjusted.  And an issue for some might be upside down print  on the back.  Neither issue is a real problem for me.   I like them a lot. They're serving their purpose and I recieve compliments on them. I recommend them and Wayfair.
