This file cabinet is OUTSTANDING!  Far better than I thought it would be. Took it slow putting it together and it went together easily. Pictured instructions were great help. Two people would make it go together faster for sure, but dont have that luxury. Id buy it again in a heartbeat. The sides are thick solid wood. Tracks for file slide could have thicker but well see how it works out. I like having 5 rolling casters, gives extra support up front... Wise choice if you want a sturdy, EZ to put together filing cabinet. Highly recommended!
