It's called the PEDRALI L002T/BA ARCHED FLOOR LAMP and you can purchase it here: http://www.nostraforma.com/en/pedrali-l002tba-arched-floor-lamp-p-16447.html

What look are you aiming for? I have a traditional bedroom with charcoal bedhead, dark almost black real wood bedsides and clear sealed hard wood floors. Search dark grey or charcoal bedhead in the photos here on Houzz. There are a good number of looks to inspire.

To be honest - they are both pretty dominant for a 2.7 m stud - I like the idea of multiple hanging of similar lights. You could also purchase something less expensive and think about it until you find the perfect piece - sometimes we need to live in the zone before we see what it needs. One tip re budget - if someone walked towards you with $7000 in one hand and the light fitting in the other - which would you choose - a good temptation tester !

In children bedrooms it is a good idea to make your decor items double duty by being a form of storage or a desk etc. the obvious things are duvet covers, storage baskets, cushions, curtains art. 11 year old taste will change quite rapidly so think about keeping the basics plain and using the decor items. 11 year olds are often over franchise designs so are more driven by colour and feature walls which can be changed as she gets older is also a good way for a refresh. It is wise to give her some choice but make sure they are preselected by you and that you can live with them.
