I am currently working on choosing fabrics from a different brand and there are a few factors to consider with choosing fabric that I've learned about. There may be others that some of the pros can share.

• Double rubcount - This defines how durable the fabric is. You want something at least 15,000 for heavily used upholstery like family room sofa. Higher is more durable. I am aiming to get at least 30,000.
• Content - Fabrics like polyester or olefin are usually more durable than fabrics like linen. There are probably exceptions. I've heard that linen is inclined to fade.
• Cleaning code - Determines how you can clean or spot clean fabric.
• Pill rating - Some fabrics have pill rating to determine how likely the fabric is to pill with use.
• Texture - Texture can impact how a fabric performs in a home. For example, some textures will attract pet hair more than others.
• Stain resistance - Some fabrics will list if they are stain resistant or liquid repellant. This might be important if you tend to have a lot of spills.

I see Pottery Barn does list the rubcount on the fabrics, so start there. Looks like both the Crossweave and Velvet fabrics have a very high rubcount listed.

For the record, I have never owned a Pottery Barn upholstery item. I love the look of them, but was not happy with the comfort of many that I sat on in the store and am not impressed with their construction.

Leather or Sunbrella

I've read that olefin pills. I don't know if it's true. But on pottery barn's website the olefin upholstery fabrics have lower durability ratings, 20K. Several fabrics have 40-50K, even 100K ratings.
