We started out with rolling drawers to hold things like syringes and other medical items. 1 set of drawer grew to 3, then 5 and eventually looked like a parking lot for rolling drawers. We decided it was time to do something bigger to accommodate everything in one unit. After lots of searching we found a unit at Ikea that we were able to customize to fit our needs. You can fill the cubies with bins, drawers, leave them as shelves, etc. We combined the flexibility if the Expedit shelving unit with our handy label maker and came out with a very effective medical storage system.
