It's a Gentleman's Dresser. You don't often see them intact these days. They usually are long parted out. In our family, we have the chest and the mirror, but the ornate mirror surround and two smaller side cabinets are long gone to who knows where. Candles were often placed on top of the side cabinet to illuminate the user in the mirror. It looks to me that all the hardware is original and, as you can see, the drawers are beautifully made. Some have only one of the smaller side cabinets placed off to the side. Some also have "Eastlake" style spoon carving on the drawer fronts and top of the mirror surround. In the case of our pieces, my Grandmother followed the trend of the 1930's and painted that beautiful oak pink followed later on with white. I had it stripped and refinished back to the original "golden oak" in the early 1990's. If I had to guess, this piece was original offered through the Sears catalog. You may be able to determine if that's true with a little research.

True, maybe not broadleaf. I jumped the gun, assuming the photo showed a plant larger than grass that had leaves ready to open. There's no scale to the image, like a quarter. A photo of the lawn might answer the question. It's hard to say what to do about it without seeing anything. If there are individual shoots here and there I'd leave them be and let the KBG grow undisturbed. If it is a carpet of weeds that might require some action. What state are you in? I assume it is northern since you seeded KBG. In most areas of the country this is the wrong time to seed a lawn. Unless you are in Canada or PNW it is likely that the new lawn will die out in July. If that happens then you will have an opportunity to prep the soil properly before reseeding. Is it a large area?

it would help to know where you are located and to see a closeup of the leaves. Your agricultural extension service has master gardeners who can help, or you could ask at a local nursery (not the nursery in a big box store, please)
