SOS: Ballad Dining Chairs

Help! Do any of you have the straight-back Louis or the Leonardo chairs from Ballard? I'd love to hear your opinion on the comfort level. One of my clients likes the style of the Leonardo a lot and the dimensions are perfect, but the chairs need to be really comfortable (like long dinner parties comfortable). I'd love any input you have to offer! I wouldn't ask normally, but we've been stuck on the chair situation for a while and could use some info. Please and thank you!

The plan is to pair four of these with a marble-topped Saarinen style table for her breakfast nook.

PS Thanks for all the emails on the Nate Berkus settee. I passed them all along to my old client and she'll be responding to you. xx
