I also purchased a Landon sofa from Pottery barn and spent $1600. This means that I chose the least expensive fabric but for $1600 I expected better.
My IKEA sofa held up way better not only in terms holding its shape(the Landon sofa down pillows are horrible) but also in the quality and durability of the fabric. My Landon is only 2 years old and the stitching is coming out from the bottom, the pillows are out of shape and the sofa looks like it's at least 5 years old. Their website claims that its better quality cause it's made in the USA (which I totally support) but they don't let you write reviews, on their products .
Wonder why? Well because they can't stand behind their products.
