Maybe two chairs with a table between and a floor or table lamp? Or a four seat game table? Do you need a little office space?

Before you fill the corner, are you committed to those veritical blinds? If not, I would work on new window treatments first.

@suzyq We don't need office space we have an office however, a chair or two with a side table isn't a bad idea! Thank you

I love to sit in my bay window and read. If you have a good view, put a bird feeder outside and a comfy chair and a table to hold your teacup in the corner.

Keep us posted on the changes you have planned. All sounds great.

Get a small area rug to define the space... then maybe a couple of arm chairs and small table

Yes, a small round game table and chairs would be great;)

You have lots of space and a lovely room but the rest of the room looks very dark i.e. dark floor and furniture, you may wish to introduce a much larger lively colored rug on which all the sitting room furniture seating can be arranged comfortably, then place a smaller version of the rug, possibly round, in this corner. Light colored window treatments will also offset either two armchairs and an end table or a small round games table with two to four chairs such as Margo suggests. No clutter. If you have a good electrician two beautiful wall sconces would complete the ensemble.

A couple chairs

Eliminate those verticals. A natural grass weave or woven wood shades would lightened up the environment!

The obvious answer is a nice full palm.

A nice window seat with extra storage beneath

Margo posted one of my favs - storage benches, game table, chairs and a place for some books.

I like Margo's picture, If you get a game table like that, you should hang a light above it to define the space. Even if you don't play a lot of games. It would be a cool place to hang out with your laptop or for entertaining and extra seating.
