Delivery was faster and more efficient than expected!! This piece was added to complete my home office. Looks as good I had hoped. Takes two strong people to lift it out of the well packed delivery box on to the floor. Quickly I redirected the knobs (very smart on the delivery method of screwing the knobs inside the openings). 
The shelving is fixed — limiting space usage. 
This piece delightfully worked for me. No damages, quality for the price. This was my first Wayfair purchase. I’m very pleased!
