While i love the settee, i would put in a lovely credenza and place your mirror over that.

if you need a bench and a mirror, get a larger bend and a larger mirror.

long bench and center the mirror at eye level, no matter what size you choose.

no to multiple mirrors unless they are identical, like four mirrors hung in a sq.

I don't think your current selection lends itself to a galley wall of mirrors. Something like this layout would work. Use battery operated remote control pillar candles.

If minimalism is your style no bunch of mirrors hung together anywhere would be the right choice . Even that mirror really does not work Get one large piece of art and a longer bench under the art and no DESIGNER punched plillow eiher
