I'm not really in the market for anything, I can certainly help you pick out something though!

A nice sectional could fit well in your room, maybe something like the Ikea Vallentuna.

Great, do you need any advice on any other furniture?
t will be us3ful for me. 
Sure, another good option could be the Zinus Classic at Amazon, it goes great with a medium to small sized space.
should i buy a double door dfridge or single door feidge? 
I'd recommend a fridge with two doors as it's a more logical layout and allows you to easily access items.
