What a wonderful and useful piece of mid-century modern furniture! Comprised of two separate pieces covered in walnut veneer that when combined create an incredible entertainment cabinet or bookcase or desk, corner unit or room divider. It has a lower base unit with a stop on one end and an upper unit with a leg on the opposite end. It expands and even can be put into an L-shape. The lower unit has an opening for hmmmm??? What? Books? Printer? And, a section with dividers for LP record albums! Or files. The upper unit has a top, one shelf, a drawer, and an opening for a turntable! Or printer. Closed it is 49 inches wide. Slid open halfway it is 72 inches wide and provides a knee hole for a desk chair. Slid open all the way it is 95.5 inches wide providing a lot more space for your knees! Plus, enough space above the lower unit for a television or very large monitor. Additionally, if you put the upper unit on the lower unit at 90 degrees it fits in a corner or, since the upper unit is finished on both sides, a room divider. I’m not sure I’ve ever seen such a versatile piece of furniture! It isn’t marked with a maker’s name…..but who cares! It’s fabulous! You should have it.
