Night stands are too traditional and small for headboard so good that you are considering change. Glass/metal or wood tables would work great.

i like pic and the matched colored lamps but I think lamps are too small.

Loveseat at end of bed steals away from headboard. Can you put in another room and replace with a bench?

bedspread: if you want to continue playing with turquoise, the PALEST shade would be grand for bedspread. Also cream or pale grey. White may be too stark.

Thanks for the suggestions. the room is large so I can actually move it around, I bought it as my husband sits, works and watches TV that is opposite to the wall from the bed.

You are close. Maybe, remove non-Zen like clutter. Change bedspread to comforter so it is not laying on the floor. add 4+ pillows to bed, add pillow/throw on sofa, center lamps on nightstands.

Here is a teal and gray room that can be done affordably.

I like your color palette. I do agree with bossyvossy, Your lamps are a bit off scale and need to be larger. I too would move the chaise and perhaps place it where the runner is. I would move the runner at the end of the bed. Is it blue? I think a pale green satin quilt would look nice folding back to expose white or grey sheets. Your zen is just around the corner.
