I agree too much pattern and especially all the same. 4 armchairs need a coffee table more tha an ottoman but i would choose a nice simple textured fabric for the chairs and add a rug with some pattern to sit on the carpet. Maybe even a nice light shade of sage for the chairs Maybe a nice oriental rug for some color relief from all the gold carpet then paint the frieplace wall a color from the new carpet.

Your home doesn't have the 'Global Style' appearance that would complement your fabric choices IMO and I would recommend the brown wall be repainted.

I like the idea of 4 swivel chairs, but the one you selected might be too small in scale and not loungey enough for your room. See examples of chairs below. Consider a chair that is 36" x 36".

Looks like you have the room for a wider chair with a higher back. I would also consider a table you can put your feet on than an ottoman.

Cushy and big chairs

Too small ottoman for these chairs

These don't look terribly comfortable and the ottoman is too small

Pitch on these chairs is so more conducive to lounging

A wood tree trunk table is always an option.

Agree with everyone. You are better off with simple fabric for the swivel chairs and patterned fabrics in the accessories such as pillows or a rug.
