Very pleased with the 2 drawer filing cabinet. It arrived when Wayfair stated and came flat packed.
The instructions were very comprehensive and I had no problem assembling the unit on my own.
The unit takes A4 sized papers and folders and the large bottom drawer is very spacious. The smaller upper drawer is ideal for paper and smaller items. Both drawers move smoothly on runners and open and close easily even when full. There is then an open spaced area for more paperwork and the top can be used for display or as I have done a filing tray to take daily papers and mail. The unit stand on four castors, the front two which can be locked to ensure no movement in situ.
Overall I am very pleased with the unit, the quality and the appearance. The dark wood complements existing furniture and the steel frame is reassuringly sturdy. 
I would certainly consider a further purchase from this company.
