We moved from a 4100 sq ft home last spring and that is when my shopping with Wayfair started. With much lass storage space these pull outs are in our bath rooms. One set went into the master back room under the sink and stores so much. Lots of items like hair gel, fingernail polish remover, hair spray and misc items on one side. the other half has my wood glue, toilet cleaners, stain cane, caulk, wall patch and misc items that I use and don't want them mixed with my husbands because then I won't know where he has them and he can not use my stuff. the other bath room got one half and has hand soaps, TP vinyl gloves, candles and misc item. The other single one ended up in a kitchn lower cupboard with pop corn air popper, waffle iron setting on it's side, meat grinder and perhaps a bottle or two of wine. 
Just wonderful helpers.
