Looking for help selecting one more chair to go with the furniture we have ordered:

Sectional couch: https://www.castlery.com/us/products/todd-extended-sectional-chaise-sofa?material=light_gray&orientation=right_facing

West elm chair: https://www.westelm.com/products/mid-century-leather-show-wood-chair-h1423/?pkey=cliving-room-chairs

My husband would like a swivel chair with ottoman (otherwise we would have just ordered 2 of the west elm chairs and called it a day). But he wants to be able to turn the chair towards the living room, or to the right to look out the picture window. I created a mock up of the layout we're thinking (furniture is FPO so ignore that) but its to scale:

Just not sure if getting another tan leather chair would work or risk the leathers not matching and looking weird? What style? Not sure what direction to go in order for them to all go together and not clash in look and style. Thanks!
