Trading Places is the neatest consignment store I've been to in Boise. It has two locations and both have very high-quality used furniture of all types. The prices are very reasonable, and the employees are very friendly.
I have never consigned any furniture, so can't rate the procedure for that, but as a retail establishment, it is great! If you are in the market for some "new" furniture, but don't want to pay "new" prices, check this store out! You won't be disappointed.
