Black metal and rattan will be uncomfortable to lean against..either reading or watching TV in bed. I love my padded headboard purchased through an upholsterer in a fabric and with your great blue color you should be able to find a great fabric to cover it with. The pillows are fine.

Even with the windows right there?

I vote for rattan over metal for that room. also consider wood, or like threers suggested -- a padded board. if you do choose a hard surface, note it'll be more comfortable if it's slightly angled back.

Christy B: especially with the windows there! without a headboard, one couldn't sit up in bed, they'd fall into the window frame. overlapping is fairly common. I like how it lends a layered look.

agree with the posts that say upholstered headboard is fine with overlap with window. I would suggest euro shams to go with the other pillows. looks like you have a king bed so you will want 3 euro shams. the inspiration pic above shows 3 euro shams

I think it really depends on what style you like. Personally I love metal frame beds (ours is black metal). We've had it for 9 years and I still love it. It kind of has that vintage look. We just did 2 large euros and we lean against those when we are reading or watching tv. It's worked out just fine. Curtains would look beautiful and add a nice layered look to your room. Love the color you chose for the wall. Your white trim makes it pop!
