This is a great sturdy storage unit for small rooms, like in our rustic country cabin. Love the colour blend with our other main wood & electronic pieces. I use it for all my soap-making trays and supplies while keeping things out of the dust. The back is a solid cover but has opening in each compartment (size of a tennis ball to pass)  for stereo/TV wiring etc. But I don't recommend it as the doors will have to remain open to use the remote control. It took us less than 2 hours to assemble. So very happy with my purchase. TY Wayfair
