Go with either the circles or the 6-sided thingies. The other two patterns look too heavy with your black leather.

I like #3 best. The tweed design is nice gives texture and is neutral. It will go with both sofa and chair.

Add the "Pop" with pillows and throws. Stay with the brown, beige and green. Also please remove those cones off the edge of the mantel. Thank you.

I like the second chair and second fabric from left.

I believe when you look at the cones, you see all that they mean, you get what they are. when someone looks at them and does not know what they are, they are just black and red paper cones or megaphones, not an appealing concept? Sometimes decor is about that. Is it something you want to explain all the time?

About the chairs, I love the first one, but I wonder about comfort, i might be comfortable in that size but would guests, also that fabric - at least in that pic would not go with your furniture. The second chair seems like a better fit both for guests and in color. It looks like it would provide a lightness to the space.

Regarding the fabrics, i too like them all, but I am into soft furnishings. If you get one with a pattern, that is what you have til the chair gives, or you invest a large some to recover. Whereas, if you get one of the last two, your chair is still unique, it goes very well with your current color scheme. Lastly, it allows you to change with the seasons and/or styles. Much less to get a new pillows, curtains, throws, lamps, or rugs to keep up to date. right this minute, most of us could give you at least 3 different rooms, throw in a patterned chair it becomes harder to do.

I like the second pattern!
