I can only comment on the twill one, I also purchased another one to use in the winter, looks more suede like fabric. The twill is stretchy and fit my chair well.. its a tad big but that's okay. There are 2 big dogs jumping on the fabric, it would stay tucked in otherwise. Seems like it will be durable. The gal I spoke to when ordering was so helpful and great, and to my surprise there was 2 really nice kitchen towels in my order complimentary! Super reasonably priced also. Very pleased with this company !
