Wayfair was the only place I could find matching 36" wide shelving units in different heights. I ordered two of each so I could place the same size together front to back for greater depth. They will be used for basement storage. I received the shelves within a few days and they are very good quality. Glad I spent the extra money for the higher shelf capacity (250 lbs). They were easy to put together and manageable to move. The pricing from Wayfair was better than from other vendors, and the free shipping definitely made a difference. I look forward to further purchases from Wayfair.
