Extra overhead storage shelves

That sounds really plausible and wouldn’t surprise me. Still can’t figure out how they went together. Very solid

I hope someone shares @JanandDave shelf mod with the factory. This doesn't alter the appearance and provide some more useable storage. It's brilliant....not sure where you live, but I would pay you to make me one. Brilliant!

I did share this post with a person at the factory who will send it to the correct person in the R&D department. They are always trying to figure out how to make the future T@B’s owner’s lives easier

Ikea sells those rails and standoffs for the purposes of using hooks to hang things from the rods (utensils in kitchens, towels, etc.) and as drawer handles.  Instead of being suspended horizontally it looks the same idea but mounting them vertically.  They sell them in lengths from 9 5/8" up to 33 1/4" long so you might have to use two of them to span 6 feet.  Here is a link https://www.ikea.com/us/en/catalog/products/60138759/
