Our Modern Space Shopping Cart & 360° Swivel Wheels | Foldable Collapsible & Lightweight | Perfect for Groceries Laundry Utility Cart - Black

I was gonna suggest using a box or basket while sitting on the floor! And OP could potentially sit on a skateboard or one of those "mechanic creepers" (the rolling boards mechanics use when they get under a vehicle), a lot of which look like they convert between a stool and basically a bigger skateboard. Edit to add: for moving stuff from room to room, a tiered chronic illness cart like the RÅSKOG from Ikea or a wheeled shopping basket like this one from Amazon, or even just a wagon might do the trick like this foldable one from Amazon.
