Welcome mvaldemar! Being new to this I won't be much help to you except to say, beautiful finds!
Does your trunk happen to have tin plating? The reason I'm asking is I have been on the lookout for a chest or trunk for my daughter and came across this last night. The extremely brief description (whether accurate or not) lists it as Victorian (1890's) with pressed tin covering.
I'm sure you'll get responses regarding your chair from those who are very familiar with furniture styles and dates.
Have you found any makers marks anywhere?
