lumiere2568 Ignore furniture in the picture...that won't be in the finished room. :)

pcmom1 What kind of activities will be happening here? Guys, gals or both?

For a hang out, fusball table? Tv on low console, with those rocking sit low to the floor chairs. At the end of the room under the two windows, a day bed would fit that could double as sofa.

I imagine your teens have ideas of their own also.

Carolyn Albert-Kincl Design I'd put a 36"-42" round table with 4 chairs in one half of the room. Then I'd fill the other end with a small sofa against the 7' wall with a sturdy coffee table in front of it. Opposite the coffee table I would place 2 slipper chairs. Add colorful pillows and artwork, plus area rug in sofa/slipper chair area (5x8').

It would be good to remove the ruffled valances. They're not necessary and will not be appreciate by the teens who might prefer simple bamboo shades or wood blinds.

Carolyn Albert-Kincl Design Almost needless to say, you would hang a TV on an articulating art on the wall where the desk is now. Place small bookcase or chest under it.

Jamie Herzlinger I have teenagers and my house is the hangout. I suggest low sectional seating, and very little furniture. They want to play games on the television and watch movies. Roche Bobois has great sectional seating by Kenzo which is what I used. If you go to JAMIESHOP.COM you can look at their entire line and at over four hundred manufacturers that are for designers only, but thru JAMIESHOP.COM you are able to purchase from them at wholesale!

Jayme Hobbs If it's also for a media room/I'd get a stream lined (narrow in depth/width) computer table/ if video games/get one of two easily moveable "game" chairs for kids. A Futon may work/or a smaller love seat vs a sofa. With only a 7 ft. depth to the room/measure things first and use masking tape or something to imagine it there in the room...will be hard to walk around anything that sticks out very far/unless it's on the 7 ft. wall. Good luck!

greenthumb2 look at net chairs. they are so comfortable! :=) I will post a link.

you'll have to search for these to find a deal but they are super comfortable.

Right, they don't go with your room design but that is an easy fix. color and yes, the valances should go, or dye them something crazy to match the "new teen" look.

greenthumb2 could put two tall computer tables up against the wall where the current desk is now. But that would mean $$ for more chairs and $$ for two more tables. yard sales, thrift stores for some accessories but don't scrimp on the chairs, unless of course you find a deal!

specks31 Add floating shelves or wire-suspended shelves for games and books in light-colored wood, but no dark wood or white paint. Hanging chairs are great, any kind in solid colors. Swiveling arm chairs are also good. Anything with movement will help the room feel lighter. And definitely remove the valances. Geometric furniture and open-backed storage towers will make it all feel more modern. Will your teens do their homework here? If so, use track shelving with a bigger shelf on the bottom for a desk, and don't forget hooks for backpacks.

Custom Home Planning Center Unlike the older folks this is a great bet for those 20 and less.

lumiere2568 Thank you for all the great ideas! Valances will go to help open up the room and the old mini-blinds will be replaced. I like the beanbag and sectional ideas. TV on an articulating arm is a definite so it could be viewed from anywhere. You've given me a few fresh, new ways to think about this room that has always been painful for me to decorate. Again, thank you!

karelina How about asking the teens? They'll more likely buy into the space if they have input into the decoration and what's needed.

Carolyn Albert-Kincl Design I bet they've already been asked, but I'd love to hear what they said!

judyg Have nothing to add except "yeah" to you for making a space for your kids to bring their friends. Best to have them under your nose, so whatever it takes. :>) Need this, though.

mpoulsom these chairs are kind of cool too....but love the big bean bag chairs up above! and a fun cool hanging light fixture! Gotta have the mood lighting! :)
