The problem with every rental place I've seen is how expensive they are. You could just buy the furniture outright for the cost of three months rental. Doesn't exactly match the year lease does it? :-/
There is a used market for IKEA furniture, and they're swapped regularly on Craigslist for half price assembled. Sometimes you can even rent for "free" by buying used and selling later. New items can be sold at half price as well. So I haven't had as much difficulty with that, though I wish they had more "modular" i.e. snap together furniture.
So there are some challenges to this endeavor, good luck.
