I don't want to spend my few free hours driving around flooring warehouses, looking at low-res pictures of furniture on websites like wayfair, etc, I just want to sit/stand comfortably at home and see how things will be at the end and customize it easily.
This could theoretically be a business. If you're gonna be spending tens of thousands of dollars on a renovation, it'd make sense to rent a headset for a few weeks while you decide on everything. And since there's a strong purchase intent, you can sell real stuff (floors, tiles, furniture) through the app as well.
