I am interested in possibly purchasing 4 of the above. My concern is stability. Given the restocking fee and the return shipping costs I am reluctant to buy all 4 without sitting in one first. I live in Phoenix Arizona. Do you have a dealer locally who stocks the item. I thought of purchasing just one if we could put three on hold? I would hate to purchase one, like it, and then find out there are no more available. Given that you are likely ship these all the time what would you estimate the return shipping cost would be from 85014?
