Pillow Recommendations for "Utility" Purposes

Re: Pillow Recommendations for "Utility" Purposes.

Will be using two pillows more or less as "armrests"...so looking for function over form.

My main question is, if going for a leather/fabric combo on the pillows, what kind of fabric and leather should I be focusing on or eliminating from my search?

Thank you.

Leather on Leather will slide, so I always like to have one side suede or a "grabby" kind of fabric vs an all-leather pillow. Suede is best, it doesn't slide on leather.
