Lots of ideas....couldn't resist adding my two cents. i copied your photos and did a little cut and paste- it's messy, but hopefully gets the main idea across. i'd put your sofa in front of the large book case, chair by the fireplace, tv on the stand on the wall opposite the fireplace - so you can either look at the fire or the tv. Someone suggested using frames of one color for your photos - an inexpensive way to do that would be to spray paint them all a dark color-black goes with everything. Since your shelves are a medium tone wood, display things that are dark or light so that they contrast against the wood. Limiting your display items pallette to a few values usually helps to unify things. (I think that's why so many people want to paint the shelves or put inserts in the back to help your nice things read more clearly...some get lost). If you want to "splurge" -you may consider having a carpenter make a few solid tall cabinet doors to provide a visual break in the shelving. I'm showing 3 doors - 1 on the right side of the fireplace and 2 on the left to leave two open vertical shelves for display on each side - with things arranged to frame the fireplace as the focal point. To add some height to your big vases, consider stacking some books beneath them. Enjoy experimenting untill you get something you're happy with - good luck!

Just a quick note to thank you all for sharing your thought, ideas, experience and time. I especially want to thank Bluenan and decoenthusiaste for being with me through the all process for the last 6 months or so..., just wanted to post few photos of the results (https://www.houzz.com/discussions/any-ideas-for-final-touches-to-this-living-dinning-room-dsvw-vd~569586) as I feel it is not only me who created this space but it is your creations as much as mine. It may not be perfect or according to the the "Rules", but it is Me and my family. Each and every piece was chosen by me in different parts of the world and each one of them has a unique story behind. I am very pleased with my space. I love it! I am very blessed. .... and so I am off to my new project now... Back to school.... that's really going to be hard ;) Thank you all, once again.

Hi snan - to address your questions: 1 - yes, the lamps work very well. With regard to the height of the larger lamps: do you know how high they would be? If the bottom of the lampshade is even with the top of the pillows that should work. If they are taller than that I think you will be okay with the smaller lamps. Look back again at some of the pictures above to see what I mean. The thing that will look odd would be if the top of the lamps were taller than your headboard. The idea is that when you are in bed reading a book that you want the light to be able to reflect down. As far as the lampshade size goes on the smaller lamps I'm thinking the shorter ones since they don't seem to drop down as far as the larger ones. 2 & 3-Definitely chair by the mirrored bedside locker with one white locker on the other side. Without question. The chair to the left of the bed gave the room life. Use the extra white one in a closet or another room. You don't want to overcrowd your room when you are going for a tranquil setting. 4-Absolutely okay to have bedside tables that don't match and look good in the room. Whether or not you like that is a personal preference though. I would only put the mirrored one next to the bed though if you have the chair next to it. It's how they play off each other that makes it work. If you don't keep the chair next to the bed then I would use both white tables beside the bed. It is also fine that the pictures are off-centre to the wall as long as they are centered to the bed. :)

Take out sofa, use beanbags and those blow up seats for their friends. Coloured rugs for tumbling and crawling on. Supersoft teddy bear blankets so they can curl up. Add in one of those soft blanket boxes for toy storage and so you have somewhere soft to perch when you are with them. Paper half way up the wall in the wall paper that kids can draw on, so they can decorate in whatever colour they like and you won't mind. A childs lift up desk, bookcase and some crazy lamps in weird colours. Then close the door, collapse on the sofa that you have moved, breathe a sigh of relief and thank your lucky stars that you have another room for the kids to go to. (Grab wine and pretend they aren't yours for half an hour! ;-) )
