I am looking for new leather sofa with ottoman and loveseat and two chairs.

Can't tell what the square footage is, but I would float a sofa perpendicular to the right side of the FP and a pair of swivel chairs opposite the sofa or FP that could turn to the TV. All of them would surround a large area rug. I assume the TV will be centered on a large wall as the FP is on its wall. Arrange the seating to be centered on both focal points.

Loveseats are not as versatile as chairs. They usually only seat one person because people don't like to sit side by side to converse, and love's offer no space to turn and face the person your are talking with. Try a sofa and four chairs. This arrangement would work for you. These are all swivel chairs, but you could just use two swivels on the TV side of the space so they could turn for viewing TV.

I have this same issue, too. How did you end up arranging your furniture, and how is it working?

I agree with decoenthusiaste. A love seat can be really hard to work with, takes up more space than a chair, and usually only one person uses it at a time. I would rather use two sofas and chairs, or one sofa and chairs. my favorite is two sofas if you have enough space.
