These covers are great.  I bought them to cover dining chairs with a curved back (they curve inward to wrap around the back of the person sitting in them).  I picked these because they’re stretchy and I thought they have a better chance of fitting my chairs than covers that are not elasticized.  They are perfect!  They protect my chairs from food spills and they have the added bonus of being the delight of my cats who love to hire under the skirts these covers create on my chairs.   They’re perfect!
