I was there a couple of weeks ago, but mainly just spent time in the basic hard chairs/tables adjacent to the bar, so I didn't notice all the stains on those light bright colored chairs near the windows (as it's been months since I visited this lounge and of course it still looked great in the early fall when visited and made my first impression). But, having seen the pictures on another thread of what they look like now, they look bad. Flyertalk member Rustykettel was right. Those hipster colors with cloth covering for the new C lounge was a dumb choice by Alaska.
