These shelves are custom made for a retail store environment. The owner requested floating shelves and three 36" floor standing units. The long one s (111-1/2" in length) were too long in my opinion to remain full floating. So I added some balusters as legs. We felt they matched the decor well and did not detract from the low profile, sleek, look of the other floaters. I later built 6 more floating shelves and installed a 47" LED TV.
