I assembled these myself, but would say 2 would be a lot faster and eqsier.. I also put it in a corner. The left part and middle meet in the corner, so you can move this about and does not have yo be straight across. Massive amount of hanging space. Far more than you could have in a wardrobe! I used this for a temporary measure, however have not felt the need to change at the moment. You can of course use this as a temporary open option or in conjunction of separate sliding doors as I have in another room. Versatile and cheap
