$300 for this low-profile dark blue upholstered chair is steep, but could be worth it IF the fabric is high-quality and in good condition, which I can't confirm from the pictures. Real nice though.
A quick tip for you: searching "pairs" or "chairs" will most likely give you sets of seating, which in my opinion are always more valuable than singles. That's how I found these two gold leather wing backs. They would very much work with my color scheme, and leather (or faux, like these almost definitely are) is easy to clean. Plus, $150 for the set? C'mon now. Even I can afford that.
Although they won't work in my living room, this is a set of 7 chairs for $25. Wha? They're so fun!
